The PRESIDENT: Please be seated. The sitting is open. The Court meets today, pursuant

to Article 74, paragraph 3, of the Rules of Court, to hear the observations of the Parties on the

Request for the indication of provisional measures submitted by Nicaragua in the case concerning

Construction of a Road in Costa Rica along the San Juan River (Nicaragua v. Costa Rica). This

case was joined with the case concerning Certain Activities carried out by Nicaragua in the Border

Area (Costa Rica v. Nicaragua), by two separate Orders of the Court dated 17 April 2013.

Each of the Parties in the present case, the Republic of Nicaragua and the Republic of Costa

Rica, has availed itself of the possibility afforded to it by Article 31 of the Statute of the Court to

choose a judge ad hoc. Nicaragua chose Mr. Gilbert Guillaume and Costa Rica chose

Mr. Bruno Simma. By a communication dated 17 April 2013, Mr. Simma informed the Court of

his decision to resign from his functions, further to the aforementioned joinder of proceedings.

It is recalled that, in the case concer ning Certain Activities carried out by Nicaragua in the

Border Area (Costa Rica v. Nicaragua), Costa Rica chose Mr. John Dugard and Nicaragua,

Mr. GilbertGuillaume. Judges Guillaume and Dugard were each installed as judge ad hoc in 2011,

during the phase of that case devoted to the Request for the indication of provisional measures

submitted by the Republic of Costa Rica on 18 November 2010, and continue to sit for the

purposes of all phases of the joint proceedings.

*

I shall now briefly recall the p rocedure so far followed in the Nicaragua v. Costa Rica

case — case relating to Construction of a Road in Costa Rica along the San Juan River . On

22 December 2011, the Government of Nicaragua filed in the Registry of the Court an Application

instituting proc eedings against the Government of Costa Rica for “violations of Nicaraguan

sovereignty and major environmental damages on its territory”, contending, in particular, that

Costa Rica was carrying out major works along most of the border area between the two countries

along the San Juan River, namely the construction of a road, with grave environmental

consequences. - 9 -

By an Order of 23 January 2012, the Court fixed 19 December 2012 and 19 December 2013,

in light of the agreement reached between the Parties, as the respective time-limits for the filing of

a Memorial by Nicaragua and a Counter-Memorial by Costa Rica. Nicaragua’s Memorial was filed

within the time-limit thus prescribed.

On 11 October 2013, Nicaragua filed in the Registry a Request for the i ndication of

provisional measures in the present case. Nicaragua clarified that it was not seeking the

modification of the Order of 8 March 2011, but rather “the adoption of new provisional measures

linked with the Nicaragua v. Costa Rica case”.

The Registrar immediately communicated a copy of the said request to the Government of

Costa Rica.

Nicaragua, in outlining the facts which led it to bring the present request, states that “Costa

Rica has repeatedly refused to give Nicaragua appropriate information on the road works” and “has

denied that it has any obligation to prepare an E nvironmental Impact Assessment or to provide

such a document to Nicaragua”. Nicaragua contends that,

“[a]s the rainy season enters into its heaviest stage washing even greater quan tities of
sediment and run- off into the river’s waters, Costa Rica has still not provided the
necessary information to Nicaragua, nor has it taken the necessary actions along the
160 km road to avoid or mitigate the irreparable damage that is being infl[i] cted on the
river and its surrounding environment, including on navigation and the health and
wellbeing of the population living along its margins”.

I shall now ask the Registrar to read out the passage from the Request specifying the

provisional measures which the Government of Nicaragua is asking the Court to indicate.

Monsieur le Greffier, vous avez la parole.

The REGISTRAR: Merci.

“Nicaragua, therefore, respectfully requests the Court, as a matter of urgency to

prevent further damage to the River and to avoid aggravation of the dispute, to order
the following provisional measures:

(1) that Costa Rica immediately and unconditionally provides Nicaragua with the
Environmental Impact Assessment Study and all technical reports and assessments
on the measures necessary to mitigate significant environmental harm to the River;

(2) that Costa Rica immediately takes the following emergency measures:

(a) Reduce the rate and frequency of road fill failure slumps and landslides where
the road crosses the steeper hill slopes, especially in locations where failed or - 10 -

eroded soil materials have been or could potentially be delivered to the Río
San Juan.

(b) Eliminate or significantly reduce the risk of future erosion and sediment
delivery at all stream crossings along Route 1856.

(c) Immediately reduce road surface erosion and sediment delivery by improving
dispersion of concentrated road runoff and increasing the number and
frequency of road drainage structures.

(d) Control surface erosion and resultant sedimen t delivery from bare soil areas
that were exposed during clearing, grubbing and construction activities in the
last several years.

(3) Order Costa Rica not to renew any construction activities of the road while the
Court is seised of the present case.”

The PRESIDENT: Merci. According to Article 74 of the Rules of Court, a request for the

indication of provisional measures shall have priority over all other cases and the Court, if it is not

sitting, shall be convened forthwith for the purpose of proceedi ng to a decision on the request as a

matter of urgency. The Parties were informed that the date for the opening of the oral proceedings

contemplated in Article 74, paragraph 3, of the Rules of Court, during which they could present

their observations on t he Request for the indication of provisional measures, had been set at

5 November 2013, at 10 a.m.

I note the presence at the hearing of the Agents, c ounsel and Advocates of both Parties. In

accordance with the arrangements on the organization of the pro cedure decided by the Court, the

hearings will comprise a first and a second round of oral argument. Each Party will have one full

session of three hours for the first round and a session of one -and-a-half hours for the second

round. These are of course maximum speaking times, that the Parties ought not to use if not

necessary.

Nicaragua will present its first round of oral observations on its request for the indication of

provisional measures this morning. Costa Rica will present its first round of ora l observations on

that request on Wednesday 6 November, at 10 a.m.

Nicaragua will then present its second round of oral observations on Thursday 7 November

at 10 a.m., for a maximum speaking time of one -and-a-half hours. Costa Rica will then present its

second round of oral observations on Friday 8 November at 10 a.m., also for a maximum speaking

time of ninety minutes. - 11 -

The PRESIDENT:

Before giving the floor to His Excellency Ambassador Carlos ArgüelloGómez, Agent of

Nicaragua, I shall draw the attention of the Parties to Practice Direction XI, which states, inter alia,

that Parties should:

“[i]n the oral pleadings on requests for provisional measures . . . limit themselves to
what is relevant to the criteria for the indication of provisional measures as indicated
in the Statute, Rules and jurisprudence of the Court. They should not enter into the

merits of the case beyond what is strictly necessary for that purpose.”

So the purpose of this hearing is to provide an opportunity to the Parties to addres s the

request of Nicaragua to indicate provisional measures in Construction of a Road in Costa Rica

along the San Juan River (Nicaragua v. Costa Rica). The Court has already closed the arguments

on the request of Costa Rica for the indication of provisional measures in Certain Activities carried

out by Nicaragua in the Border Area (Costa Rica v. Nicaragua), on 17 October 2013 and it is in an

advanced stage of its deliberation. You will shortly hear from the Registrar of the Court and the

Parties will be convened to this Great Hall for the purpose of the delivery of the Order by the Court

in that case. I shall now give the floor to His Excellency Ambassador CarlosArgüello Gómez,

Agent of Nicaragua. You have the floor, Sir.

Mr. ARGÜELLO GÓMEZ:

1. Mr. President, Distinguished Members of the Court . Good morning. As always it is a

great honour to address you on behalf of my country.

2. I should add at the start that I would have preferred to have had this honour of addressing

Nicaragua’s request for pr ovisional measures that is now under consideration, during the previous

hearings of last October . This is not to say that we do not understand the reasons for having

separate hearings, particularly in view of the fact that Nicaragua introduced its request at a late

stage.

3. This deserves an explanation. This was no last moment add- on. During the previous

request for provisional measures filed by Costa Rica, Nicaragua presented a letter to the Court on

10 October 2013 accepting the facts as generally claimed and indicating that the situation had been - 12 -

immediately stopped once the President of Nicaragua became aware of it, and that steps had been

taken to avoid any recurrence of these events.

4. Our view of the situation was that with this explanation the request for new provisional

measures requested by Costa Rica had become moot and that it might be withdrawn. It was only

after Costa Rica rejected as insufficient the statement by Nicaragua and insisted that the hearings

continue that we determined to f ile our own petition for provisional measures with the intention

that they be pleaded during those hearings . The reason of joining Nicaragua’s request to that of

Costa Rica was due to the fact that Nicaragua wanted to avoid the expense and inconvenience f or

the Members of the Court of having separate public hearings . As can be appreciated from a brief

summary of the procedural history in the short review below, Nicaragua had already made several

attempts to obtain some form of protection of its rights without going through the formal process of

public hearings.

5. Unfortunately this has not been possible and we must inevitably tax the Court’s time.

Effect of the joinder of the two cases

6. Mr. President, the present hearings involve in one way or anothe r two cases presently

before the Court that have been joined by the Order of 17 April 2013. One case was brought by

Costa Rica against Nicaragua ( the Certain Activities case) by means of an Application filed by

1
Costa Rica on 18 November 2010 and the other case was brought by Nicaragua against Costa Rica

(the Construction of a Road case) by means of an Application filed on 22 December 2011 2.

7. For this reason, please allow me to reiterate the statement made in our letter of

11 October 2013 requesting the provisional measures now under consideration. This letter stated:

“Nicaragua would like to point out that although it has filed a case against Costa
3
Rica for the construction of a Road (Road 1856) , the damage done to the River by the
construction of t his road also constitutes an independent aggravation of the dispute
under consideration in the case concerning the Construction of a Road in Costa Rica
along the San Juan River (Nicaragua v. Costa Rica). The damages caused by the road

are an inextricable part of the case concerning Certain Activities carried out by
Nicaragua in the Border Area (Costa Rica v. Nicaragua), as explained in Nicaragua’s

1Available at http://www.icj-cij.org/docket/files/150/16279.pdf .

See the Application of the Republic of Nicaragua instituting Proceedings against the Republic of Costa Rica,
21 December 2011. - 13 -

pleadings, Costa Rica’s road works have caused a surge in the San Juan River’s
sediment load requiring Nicarag ua to take active efforts, including dredging, to
maintain the quality and quantity of the river’s waters.” 4

8. This was also the reason why in my Agent’s speech during the hearings for Costa Rica’s
5
request for new provisional measures in the Certain Acti vities case on 15 October last , I pointed

out the damages caused by the roadwork and the need to put a stop to this day-to-day destruction of

the river system . What I stated in that speech is equally applicable during these hearings for

provisional measures in what Nicaragua understands are joined cases.

Background of the dispute

Certain Activities case: territorial dispute

9. In the Certain Activities case, Costa Rica claims sovereignty over a wetland of

approximately 250 hectares located at the mouth of the San Juan de Nicaragua River which

Nicaragua also considers part of its sovereign territory.

6
10. The area in dispute was demarcated in the first Alexander Award . In the pertinent part

the Arbitrator declares that the initial line of the boundary w as to run as follows:

“Its direction shall be due northeast and southwest, across the bank of sand,
from the Caribbean Sea into the waters of Harbor -Head Lagoon. It shall pass, at its
nearest point, three hundred (300) feet on the northwest side from the small hut now
standing in the vicinity.”

11. On the screen [ tab 1] we can observe that this line crosses the sand bank already in

existence since that time, leaving sovereignty over it on the Nicaraguan side, and then the line runs

into Harbor Head Lagoon, from where, the Award states:

“the boundary line shall turn to the left, or south eastward, and shall follow the water’s
edge around the harbor, until it reaches the river proper by the first channel met . Up
this channel, and up the river proper, the line shall continue to ascend as directed in

the treaty.”

12. For Nicaragua this means that the first channel or caño is located inside Harbor Head

Lagoon and from there it runs into the river proper. For Costa Rica the first channel runs out to the

sea and not into the river.

United Nations, Reports of International Arbitral Awards (RIAA), Vol.XXVIII, p. 220 (MCR, Vol. II, Ann. 9, p. 69). - 14 -

13. This difference of opinion crystallized into the territorial dispute over the 250 hectares of

swampland [tab 1 off].

Certain Activities case: dredging and cleaning of the San Juan and its channels

14. The other claim of Costa Rica in that case is that Nicaragua should cease any dredging

activities in the last 30 kilometers before the r iver reaches the sea, and to cease all activity in any

other part of the river that could cause damage to Costa Rican territory.

15. This question has been at the heart of most disputes with Costa Rica over the San Juan

River for over 150 years. At present, approximately 90 per cent of the waters of the Nicaraguan

San Juan River find their outlet to the sea through the branch of the Colorado River that runs

entirely in Costa Rican territory . Nicaragua’s position is that the Jerez -Cañas Treaty of 1858 and

the Cleveland Award of 1888 make clear that Nicaragua has a right to dredge the r iver and its

channels to maintain the situation in place in 1858.

Provisional measures

16. As a corollary to its Application instituting proceedings against Nicaragua, Costa Rica

also filed a request for provisional measures . The Court decided to o rder certain measures on

8 March 2011. One of these measures was that

“Each Party shall refrain from any action which might aggravate or extend the
dispute before the Court or make it more difficult to resolve.”

Construction of a Road case

17. After this Order on provisional measures was given, Costa Rica embarked on the

construction of an extremely damaging and environmentally destructive road, which its President

hastily authorized by emergency decree. In building the road, Costa Rica bypassed its normal

vetting processes, and failed to carry out an Environmenta l Impact Assessment . The inevitable

result was shoddy design and construction  condemned by Costa Rica’s own Association of

Engineers and Architects 7 amounting to an environmental nightmare. What I want to emphasize

See Ann. 4 to the Memorial of the Republic of Ni caragua in the case concerning the Construction of a Road in
Costa Rica along the San Juan River (Nicaragua v. Costa Rica), 19 December2012. - 15 -

is that the damages to the San Juan River and its protected wetlands caused by the roadwork

prompted Nicaragua to bring a case against Costa Rica before the Court on 22 December 2011.

18. The construction of this road was justified, according to Costa Rica, for security reasons

subsequent to the activities in the disputed territory . On the basis of an emergency decree this road

was constructed without environmental impact assessment and without any elementary

environmental precautions or regard for good neighbourliness.

19. In fact the reckless and unfriendly construction of the road was largely a product of spite.

This is exemplified by the statement of the second Vice- President of Costa Rica, Alfio Piva, who

indicated that since the new road being constructed made the r iver unnecessary for Costa Ricans,

8
he called upon Nicaraguan’s to “eat the San Juan [River]” .

20. The fact that the road was designed and executed without any environmental

considerations, or concern for the risks to the contiguous territory of Nicaragua, has been

acknowledged by the highest authorities of Costa Rica . On 13 December 2011, the President of

Costa Rica, Ms Laura Chinchilla, declared that Costa Rica “ issued an emergency decree due to

national necessity and it is on that basis that we have developed the pro jects. We are not taking

even one step back.” 9 Accordingly, President Chinchilla concluded, Costa Rica has “no reason to

10
offer explanations to the Government of Nicaragua” .

21. Foreign Minister of Costa Rica, Minister Castillo, stated also with Olympia n disregard

that his country is not obligated to give any kind of explanation, “ nor to suspend its work being

carried out as a consequence of an emergency provoked by Nicaragua” and declared : “This is a

sovereign project we are carrying out under a decree that exempts us from environmental impact

studies, that is why we owe no explanations ”, confirming that behind these projects there is no

study for mitigating environmental damage in the zone 1.

Impact of the road

22. The road was cut parallel and perilously close to the right margin of the San Juan River

without any consideration of the environmental consequences even inside Costa Rica, and even in

violation of Costa Rica’s internal law that prohibits such constructions within 50 meters of a river.

This disregard of all caution and legal obligations has been confirmed by Costa Rica’s

Administrative Environmental Court 12 and the reports issued by Costa Rica’s Association of

Engineers and Architects (CFIA) and Costa Rica’s National Laboratory (LANAMME) among

others issued by Costa Rica’s institutions and international experts 13. If no regard was taken of the

Costa Rican environment on the basis of a decree of a dubious national emergency, then what

regard could be expected for Nicaraguan territory and environment?

23. For example, Costa Rica’s Association of Engineers and Architects have indicated that

the destruction of the vegetation along the right bank of the river, together with the creation of

unstable, unprotected slopes and a lack of proper drainage , result in both increased land collapse,

and excessive erosion and sediment run -off into the San Juan de Nicaragua River which aggravate

the obstacles to navigating the river, and concluded that the road construction project may

14
negatively impact the abil ity of Costa Ricans to navigate the r iver . This is Costa Rica’s

Association of Engineers and Architects.

24. The reports of these independent Costa Rican institutions contrasts entirely with the

self-serving conclusions of the reports of the g overnmental institutions filed by Costa Rica

yesterday and on which we will comment shortly.

25. The Court has already had an opportunity of viewing some of the images taken from the

roadwork. A short reminder is on screen [tab 2]. [Tab 2 off]

Juan, Nicaragua, 30 October 2013”.

the San Juan River ( Nicaragua v. Costa Rica), para. 4.15 - 17 -

26. The consequences of this reckless disregard of the environment and of the territory of its

neighbour is noted in the report of ProfessorKondolf, that points out that,

“The poor siting of the road across steep, unstable hill slopes and in close
proximity to the river, was compounded by poor construction practices, which in the
United States and Europe were used in the 1950s but have been illegal for decades.” 15

27. In Spanish we have a saying “para muestra un boton” that loosely translated into English

might read “as an example a button is enough” . On the screen we will shortly see an incident that

occurred 10 days ago that evidences the poor construction practices pointed out by

Professor Kondolf. The incident involves not a small button but a large culvert that was washed

away into the San Juan River after an average rainfall . The persons you will see on the screen

collecting the debris and breaking it up for transportation are personnel from MARENA, the

environmental agency of Nicaragua. The place where the destro yed culvert was found was not

immediately in the area where it had been located . It was some distance from its original

emplacement. On screen we have a short version of the cleaning up of the culvert debris [tab 3].

28. You must have noted that the rem ainder of the culvert s hown on the screen was not

home-made, like many that have been placed along the route (for example, adapted truck

containers), but it was a regular custom-made culvert and that it was washed out quite a distance

from its original emplacement after only a normal rainfall . [Tab 3 off] What would happen to the

more numerous home-made versions during the frequent tropical storms that beset the region? In

any case there are not many left to test the issue. As reported in the Costa Rica n news media,

“The evidence that the bridges and culverts were improperly built is that almost all of them

16
do no longer exist.”

Actions taken by Nicaragua to preserve its rights

29. Mr. President, the mechanisms open for a State to attempt to preserve its rights when it is

faced by illegal activities of another S tate are not only those contemplated in Articles 41 of the

Statute and 73 of the Rules of Court, even if the preservation of its rights are a matter of urgency

and could result in irreparable pr ejudice. There are bilateral procedures, requests addressed to

international organizations and also the possibility for the Court itself to take action proprio motu.

30. Nicaragua has tried all of these approaches before deciding to request these measur es

through the formal mechanisms involved in these hearings.

Bilateral measures

31. Since the magnitude of the roadwork first became evident, Nicaragua has been

requesting that Costa Rica furnish it with an Environmental Impact Assessment.

32. On 29 November 2011, the acting Foreign Minister of Nicaragua sent a Note to his Costa

Rican counterpart requesting information on the road under construction and pointing out,

“(a) that all projects of this nature should have an Environmental Impact Assessment
17
due to their characteristics” .

33. This Assessment has never been furnished to Nicaragua. According to the statements

cited above by the President of Costa Rica and the Foreign Minister, the environmental impact

assessment was never even made. This is r ecognition of a violation of Costa Rica’s international

obligations.

Communications to international organizations

34. In view of this blatant disregard by Costa Rica of its international obligations not only

stemming from general principles of internatio nal law but also on specific Conventions to which it

is a party, Nicaragua took the steps it had ready at hand to try to obtain Costa Rican compliance

18
with its obligations . As indicated in Nicaragua’s Memorial , it proceeded to inform the

Secretariats of these several Conventions about the major environmental threats due to the

activities underway in Costa Rica. Nicaragua sent Notes to Unesco, since it relates to a Biosphere

Reserve recognized by that entity, the RAMSAR Secretariat since it also relates t o wetlands

recognized under this Convention, as well as to the United Nations Environmental Program

(UNEP) and the regional Central American Commission on Environment and Development

(CCAD), since Nicaragua has the obligation of informing them about the da mage and imminent
19
threats to our natural patrimony in the biosphere reserve at Río San Juan . These Notes also

request these international organizations to send an investigative mission to visit the affected area

and assess on the ground the harms and pot ential harms caused by Costa Rica’s violations of the
20
applicable Conventions .

Requests to the Court for ordering measures on the basis of its statutory powers

35. Since this had no effect, Nicaragua proceeded to request to the Court to order measures

on the basis of its statutory powers. When Nicaragua filed its Application instituting proceedings

against Costa Rica for the roadwork on 22 December 2011, it accompanied a Note that stated,

“(a) In its Application Nicaragua has made clear that Costa Rica is carrying out major
construction works along most of the border area with Nicaragua with grave
environmental consequences without producing and communicating to Nicaragua

an Environmental Impact Assessment (EIA) that would permit an evaluation of the
works.

(b) For this reason, Nicaragua has requested that the Court on the basis of its statutory
powers order that Costa Rica produce and communicate to Nicaragua such

document. Given the evident importance of the EIA in the circumstances of this
case, Nicaragua considers that the exercise of these powers by the Court at this
time would be amply justified.”

36. Again, when Nicaragua filed its Memorial on 19 December 2012, in the submissions it

requested the Court

“to order Costa Rica to immediately take the emergency measures recommended by
its own experts and further detailed in the Kondolf Report, in order to alleviate or
mitigate the continuing damage being caused to the San Juan de Nicaragua River and

the surrounding environment . If Costa Rica does not of itself proceed to take these
measures and the Court considers it cannot order that it be done without the full
procedure contemplated in Articles 73 et seq. of the Rules of Court, the Republic of
Nicaragua reserves its right to request provisional measure s on the basis of Article 41

of the Statute and the pertinent procedures of Articles 73 and ff. of the Rules of Court
and to amend and modify these submissions in the light of the further pleadings in this
case.”

37. In a Note dated 19 December 2012 accompanying its Memorial, Nicaragua explained

that it considered,

1Ibid., Anns. Nos. 18, 19 and 21 . Notes sent from the Minister of Environment of Nicaragua and Natural
Resources (MARENA), to the United Nations Environmental Program (UNEP), Central American Commission on
Environment and Development (CCAD) and Unesco, on the 10 December 2011.

2Ibid, Ann. No. 20. Note from the Minister of Environment of Nicaragua and Natural Resources (MARENA), to
the Secretary General, RAMSAR Convention, 28 November 2011. - 20 -

“that the Court has been provided with the necessary information in order to decide
‘proprio motu whether the circumstances of the case require the indication of
provisional measures’, without having to go through the costly and lengthy exercise of
public hearings”.

38. The attempts by Nicaragua to avoid ti me-consuming and expensive formal hearings

came to an end when it received a communication dated 11 March 2013 from the Registrar

informing that the Court was of the view that the circumstances of the case, as they presented

themselves to it at that time, were not such as to require the exercise of its power under Article 7 5

of the Rules of Court to indicate provisional measures proprio motu.

39. Even after this rejection Nicaragua made one further attempt to avoid formal hearings by

using the request made by Costa Rica on 23 May 2013 for the modification of the Order of

8 March 2011. In its written observations to this request of 14 June 2013, Nicaragua asked the

Court to reject Costa Rica’s request and at the same time requested that the Court adapt its Order of

8 March 2011 in order to embrace the situation of the joined cases and particularly to take into

account the situation created bythe roadwork.

40. In its Order of 16 July 2013 the Court rejected Nicaragua’s request indicating that:

“even if the situation invoked in the Nicaragua v. Costa Rica case were to justify the

indication of provisional measures, the appropriate method of sec uring that is not the
modification of the Order [of 8 March 2011] made in the Costa Rica v. Nicaragua
case” .1

41. With this communication it became clear to Nicaragua that the Court would only

consider Nicaragua’s request for provisional measures, if this was made in a formal request on the

basis of Article 41 of the Statute and 73 of the Rules of Court.

Renewal of the roadwork

42. Apart from all other procedural doors being closed to Nicaragua’s attempt to avoid

prejudice to its rights, another perilous situation came looming again. That is the fact that public

announcements have been made by Costa Rican authorities that the roadwork would be continued

at the end of this year . This announcement, coupled to the fact that there will be general elections

in Costa Rica in February 2014, and that repeated statements have been made by the Costa Rican

Government that it intends to finish its term of office with the roadwork finished or in full process

2Order of 16 July 2013 regarding the Request for the Modification of the Order of 8 March 2011 indicating
Provisional Measures, p. 9, para. 28, available at: http://www.icj-cij.org/docket/files/150/17500.pdf. - 21 -

of construction before the new Government is sworn in on Ma y 2014, convinced Nicaragua that it

could not wait any longer for requesting provisional measures.

43. The details of the renewal of the roadwork will be expounded by Mr. Reichler, but for

the moment I would bring to the attention of the Court that the i nformation given here has been

amply and joyfully confirmed by the Minister of Communication of Costa Rica,

Mr. Carlos Roverssi, who stated just last week on Monumental press that: “construction of the

Borderline Trail will continue to a priority piece of work until termination by the current

government and anticipates that it will also be (a priority) for the next (government) ” 2.

44. In addition, he emphasized that “the works will continue forward even though this does

23
not please Nicaragua” .

Question of awaiting the decision on the merits

45. There is an important element that Nicaragua has taken into consideration carefully .

This is the question of what further damage could happen between the filing of this request for

provisional measures and the pos sible dates for the judgment on the merits to be given by the

Court. This date is very difficult to anticipate . First of all, the unforeseeable agenda of the Court

that is subject to urgent requests for advisory opinions and other urgent measures by State parties.

46. Nicaragua has already experienced the impact of these circumstances on the agenda of

the Court in the proceedings in its case against Colombia that made it one of the longest lasting

cases in the history of the Court . Apart from these unforeseeable requests that could disrupt the

agenda of the Court, it is not possible to anticipate if there is to be a second round of written

pleadings in this case. But even in the most optimistic circumstances, it is not possible for the

judgment on the merits to be read before the works on the road are restarted as announced by the

Government of Costa Rica.

47. So, does Nicaragua have to wait at least one more year, after the end of another rainy

season and after the restart of the roadwork without any environmental impact assessment, for a

decision on the merits in order to put a stop to the trampling of its rights? In that case, Article 41 of

the Statute would be redundant.

48. In the case of the Great Belt, the projected bridge would not cause the foreseen damage

until it was completed and this was not anticipated to happen before the judgment on the merits.

The Court indicated that its decision on the merits might imply tearing down the structure and that

was a risk the respondent had to assume . In the present case, the roadwork so far constructed is

causing damage every day of the year and, as indicated in Professor Kondolf’s report, “[i]f work

continues on Rte 1856, its impact will be devastating to the areas directly affected and to

downstream receiving waters” 24. That is to say, to Nicaraguan waters.

Expert reports filed by Costa Rica

49. Costa Rica has filed more than 300 pages of documents containing technical reports that

were not prepared for these oral hearings since they date from before the request for the measures

presently under consideration was made. These documents mostly date from January to August of

this year and could have been furnished earlier and not at the last moment to the inconvenience of

the staff of the Registry and of the other Party. Naturally, Nicaragua does not have the time, in the

three hours of pleadings presently allotted to it, to respond to these documents on which it has

heard no argument yet. Nonetheless, Professor Mccaffrey will address some comments.

50. After tomorrow’s pleadings in which Costa Rica will presumably explain these

documents and base arguments on them, Nicaragua will have an overnight opportunity to address

this issue in the one -and-a-half hours allotted to it for argument . It is obviousl y not possible for

Nicaragua in one-and-a-half hours to analyse and address these extensive documents that have been

prepared during months under careful scrutiny of the Costa Rican representatives.

51. These documents were evidently prepared for fili ng w ith the Costa Rican

Counter-Memorial and reflect this purpose in many ways. They look to the past and not the future

which is the preventive objective of provisional measures . Thus, they have absolutely no

comments on the impact of the future continuation of the roadwork; they have no indication that

any environmental impact assessment has been prepared for this renewal of the roadwork; they

2Kondolf Report “ Continued Impacts of Erosion from Rte 1856, Costa Rica to the Río San Juan, Nicaragua,
30 October 2013”, p. 1. - 23 -

make no attempt to foresee the consequences that would ensue after the next tropical storm

inevitably hits the area. In fact, their only objective is to try to minimize the amount of damages so

far caused by the roadwork.

52. Due to the nature of these documents, Nicaragua reserves its rights to comment and

respond fully to them and the arguments based on them, unt il it has an opportunity to plead on the

merits, be they written or oral pleadings.

Mr. President, Members of the Court, this finishes my presentation. Thank you for your kind

attention. I will continue, simply indicating the order and general subject t o be addressed by the

speakers, which is as follows:

 Professor Stephen McCaffrey will address the irreparable harm caused by the roadwork and the

aggravation of the renewal of the works;

 Mr. Paul Reichler will address the urgent need of the provisional measures requested;

 And Professor Alain Pellet will address the specific standards for granting provisional

measures.

Mr. President, I ask you to call Professor McCaffrey, please.

The PRESIDENT: Thank you very much, Ambassador Argüello Gomez. And I now invite

Professor Stephen McCaffrey to address the Court. You have the floor, Sir.

Mr. McCAFFREY: Thank you very much, Mr. Chairman, Mr. President.

IRREPARABLE PREJUDICE TO N ICARAGUA ’S RIGHTS

Mr. President, distinguished Members of the Court, it is a great honour and privilege to

appear before you again on behalf of the Republic of Nicaragua.

1. Mr. President, Members of the Court, this case can fairly be described as one of death by a

thousand cuts: death of the Lower San Juan River by accretion, by t he slow but steady changes

wrought by sedimentation. The change s may be gradual, but they are no less inevitable, and no

less threatening to past, present and future uses of the river by Nicaragua. The change may be

incremental, but it is no less cumulative. It is accomplished by a continuing incursion into - 24 -

Nicaragua’s sovereign territory, one that results in what amounts to an ever -increasing occupation

of that territory and a slow but inexorable strangulation of the river.

2. That such a result may have been the intent of Costa Rica ’s road project all along is

indicated by the name that Costa Rica chose to give to the road  Juan Rafael Mora Porras,

Route 1856  an appellation apparently calculated to insult Nicaragua, because it refers to the

Costa Rican invasion and occupation of Nicaraguan territory — including the San Juan River and

Lake Nicaragua — during the period when Nicaragua was fully engaged with fighting off the

invasions of William Walker 25.

3. Mr. President, this continuing trespass in blatant violation of Nicaragua ’s sovereign rights

must be stopped. Nicaragua has tried to stop it through diplomatic channels — as the Agent

chronicled for you — but to no avail. Costa Rica has still not so much as provided Nicaragua with

plans or an environmental impact assessment, whether domestic or transboundary, concerning the

project. Nevertheless, as my friend and colleague Mr. Paul Reichler will discuss, Costa Rica now

appears bent on resuming road construction activities in the very near future. Nicaragua therefore

looks to the Court to halt this ongoing insult, so that by the time the Court is able to render its

judgment there will be something left to remedy.

4. My task today, Mr. President, is to address the implications of the fact that Cos ta Rica’s

road project is contributing significantly, and on a daily basis, to the filling in of the L ower San

Juan, to the conversion of those reaches of the watercourse from a river to land and impassable

wetlands and shallows. In particular, I will show that the effects of the road have caused, and

particularly in view of the imminent resumption of work on the road, threaten to continue to cause,

irreparable prejudice to Nicaragua’s rights. Mr. Reichler will then show why provisional measures

are urgently necessary.

Requirements for provisional measures

5. Mr. President, Members of the Court, allow me to turn first to the conditions for the

ordering of provisional measures, which are of course well known. The Court recalled these

conditions in its Order of 8 March 2011 in the Certain Activities case: first, that irreparable

2See CMN in Certain Activities carried out by Nicaragua in the Border Area (Costa Rica v. Nicaragua), Vol. I,
6 Aug. 2012, paras. 2.25-2.27. - 25 -

prejudice be caused to rights of the parties that are the subject of the judicial proceedings ; and

second, that there be urgency, in the sense that there is a real and imminent ri sk that irreparable

26
prejudice may be caused to the rights in dispute before the Court has given its final decision .

6. Finally, the rights requiring protection from irreparable prejudice must be plausible.

7. Mr. President, these requirements are easily satisfied in the present case. The factual basis

for Nicaragua’s Request is the urgent situation arising from Costa Rica ’s reckless and unplanned

construction of a road along the right bank of the San Juan de Nicaragua River and the imminent

resumption of work on it. The unengineered road construction has given rise to a real and

imminent risk that irreparable prejudice may be caused to the rights in dispute before the Court has

given its final decision. This risk will be aggravated greatly by the imp ending resumption of work

on the road by Costa Rica.

Rights of Nicaragua that are prejudiced by Costa Rica’s road project

8. Mr. President, Members of the Court, the rights of Nicaragua that are breached by

Costa Rica’s road project are set forth fully in Nicaragua’s Memorial in the case concerning the

road (Construction of a Road in Costa Rica along the San Juan River) 27. I will not repeat the list of

rights of Nicaragua that are being prejudiced, many irreparably, but will f ocus here on three of the

most important of them in the context of these provisional measures hearings: first, Nicaragua’ s

rights of territorial sovereignty and integrity ; second, Nicaragua’s right to be free from

transboundary harm; and, third, Nicaragua’s right to receive a transboundary environmental impact

assessment from Costa Rica, together with associated information and consultations. I will

illustrate the concrete manifestations of the actual and threatened prejudice with recent slides and

observations. This prejudice will only be magnified by Costa Rica’s imminent resumption of work

on the project.

a. Nicaragua’s rights of territorial sovereignty and integrity

9. First and foremost, Mr. President, the road project is causing irreparable prejudice to

Nicaragua’s sovereign rights, prejudice that will be aggravated if work on t he road is permitted to

resume. Nicaragua is, as the Court knows, sovereign over the whole of the San Juan River. This

point is not disputed by Costa Rica.

10. Mr. President, Members of the Court, the images you now see on your screens, which are

at tab 4 of your folders and were taken just last week, are emblematic of all that is wrong with

Costa Rica’s road project and of the project’s effects on Nicaraguan sovereign territory. You have

in this slide arrows pointing to the remains of a culvert and there is something green there, in the

background, that turns out to be erosion control fabric when you look more closely. It seems to

have failed to achieve its objective because it is washing down this channel into the San Juan River.

The observations by Dr. Matthias Kondolf during his field visit late last month are reflected in his

most recent report, filed with the Court. They indicate that these effects will in all likelihood

continue, and that they will only be made worse by Costa Rica’s impending resumption of work on
28
the road .

11. Dr. Kondolf has shown that the road was constructed so sloppily, and in such haste, that

no amount of superficial make -up can save it. In his report on his recent field visit, Dr. Kondolf

states: “It is urgent that . . . real, substantive measures be taken to repair and relocate the road . . .

These measures will not be trivial, but will require removal of large volumes of fill and their

transport to a stable disp osal site . . .”9 Yet it appears, Mr. President, that that is what Costa Rica

has been doing recently , in other words, precisely the kind of trivial measures Dr. Kondolf

indicates will be ineffective : trying to camouflage a massive, virtually irreparable scar along the

right bank of the San Juan by attempting to make it look better on the surface, when the problems

go far deeper, both literally and figuratively. The fundamental problems with the manner in which

the road was constructed have been catalogued in detail by the University of Costa Rica’s National

28G. Mathias Kondolf, Ph. D., “Continued Impacts of Erosion from Rte 1856, Costa Rica to the Río San Juan,
Nicaragua”, 30 Oct. 2013 (hereafter “Kondolf Report”).

29Ibid., p. 2. - 27 -

Laboratory and Costa Rica’s Federation of Engineers and Architects, as shown in Nicaragua ’s

30
Memorial in the Road case , and referred to earlier by the Agent.

12. Dr. Kondolf’s field visit late last m onth updates these findings. His report states, for

example: “Our field observations in October 2013 (last month) clearly showed that erosion is

actively occurring along multiple parts of the road, and that erosion control and drainage works

31
have been ineffective in addressing the serious erosion and slope stability problems.”

13. It is evident that the culvert itself was not designed and installed according to accepted

engineering standards, which are described and illustrated in S ection 3.1.3 of the Kondolf Report,

entitled “Stream Crossings” 32. If this culvert washed out, which it appears to have done, all of the

earthen fill material depicted in the sketch in f igure 2 at page 6 of Dr. Kondolf’s report in all

probability washed out with it and was ca rried into the San Juan. Dr. Kondolf and his colleagues

estimate that between 87,000 and 109,000 cubic meters of sediment are delivered into the San Juan

from the road project annually under what he calls “normal” conditions, and that “the rates would

be at least 10 -100 times higher during the intense rains associated with hurricanes or tropical

storms, which pass through the region frequently” 33. Thus, while the image of the rogue culvert in

the river is impressive, it is but a tiny part of the figurative tip of the iceberg of sediment and other

debris that is constantly deposited in the river by the road project. The image of the damaged

culvert in the San Juan is emblematic of the incursions into Nicaraguan sovereign territory by the

road project. But it is only a tell- tale sign of the much larger invasion by coarse and fine sediment

from the road.

14. And, Mr. President, it should be borne in mind that the rains can be heavier than they

have been this year. Dr. Kondolf observes: “The fact that so much fresh erosion is visible (and a

culvert has washed out) after a season with less than exceptional rains demonstrates how prone the

landscape is to intense rains.” 34

34Ibid., p. 9. - 28 -

15. These t respasses upon Nicaraguan territory by sedim ent and other debris from

Costa Rica’s road project constitute constant, and irreparable, prejudice to Nicaragua ’s rights of

sovereignty and territorial integrity  prejudice which, again, will only be multiplied many- fold

with the resumption of work. The prejudice is irreparable because neither Costa Rica, nor even this

Court, can un-ring the bell of a violation of sovereignty and territorial integrity. There can be no

restitutio in integrum for such violations. Moreover, each day brings a fresh assault on Nicaragua’s

territory, and thus on its rights of sovereignty and territorial integrity. These assaults must stop

pending the delivery of the Court’s judgment.

b. Nicaragua’s right to be free from transboundary harm

16. Second, Mr. President, Members of the Court, Nicaragua’ s right to be free from harm

emanating from Costa Rica ’s territory is suffering irreparable prejudice on an ongoing basis. The

right of a S tate to be free from transboundary harm originating in another S tate is venerable and

widely recognized by authorities too numerous to list comprehensively here. I will therefore

mention only a few.

17. In its unanimous Partial Award of 18 February 2013, the seven- member Court of

Arbitration in the Indus Waters Kishenganga Arbitration, chaired by a former President of thi s

Court, noted the recognition of this principle in the 1941 Award in the Trail Smelter arbitration 3.

It also referred to what it called “[a] broader restatement of the duty to avoid transboundary harm”

in Principle 21 of the 1972 Stockholm Declaration,

“pursuant to which States, when exploiting natural resources, must ‘ ensure that
activities within their jurisdiction or control do not cause damage to the environment
of other States or of areas beyond the limits of national jurisdiction’” . 36

The principle was stated as early as Max Huber ’s 1928 Award in the Island of Palmas case , and 37

38
again in this Court’s 1949 Judgment in the Corfu Channel case . It was reaffirmed by this Court

in its Advisory Opinion on the Legality of the Threat or Use of Nuclear Weapo ns in a passage

that was quoted with approval by the Court in the Gab ĉíkovo-Nagymaros Project case 40. In the

Kishenganga case, the Court of Arbitration concluded :

“There is no doubt that States are required under contemporary customary
international law to take environmental protection into consideration when planning
41
and developing projects that may cause injury to a bordering State.”

18. Mr. President, Members of the Court, in a moment you will see images on your screens

showing that Nicaragua ’s right to be free from harm emanating from Costa Rica ’s territory is

suffering irreparable prejudice on an ongoing basis. Costa Rica ’s road project is affecting the

San Juan, and in particular the L ower San Juan, every day. The existing sedimentation from the

road project will be very difficult, if not impossible, for Nicaragua to remove with its small

dredgers. More delay in taking protective measures will make it virtually impossible for Nicaragua

to remedy the situation. And the present sedimentation of the river threatens to be exacerbated

considerably by the impending resumption of work, as will be discussed by Mr. Reichler.

19. Mr. President, Members of the Court, you now see on your screens images that show

serious erosion and related problems along the course of the road. [narrative of images of erosion

along road] . We begin with sketches from Dr. Kondolf’s report which, in graphic form,

demonstrate some of the problems that can arise with the construction of roads on slopes. You see

the natural situation in sketch A, a natural hill slope, you see groundwater flowing downhill, of

course, infiltration of water from precipitation into the ground. Then in sketch B you see what the

effect is of cutting that slope, creating what is known as a cut slope, I’ve learnt  the water still

has to go somewhere  and what happens is that it goes down into the road and can undermine,

without proper engineering, the fill prism which you see happening in this photograph, which also

shows some failed erosion control fabric, or perhaps it is plastic sheeting.

The slide now on the screen shows cut slope failures, those are the upper side of the road and

a road that I certainly would not want to drive on, the fill slope also is failing because of erosion. It

appears that roughly a half of the road surface has been removed by this erosion. Again we see an

image illustrating different styles of cut bank failure and lots of erosion. This context view shows

that this is a complex site with multiple cuts and failures, both cut slopes and fill slopes. This slide

displays active failures of cut slopes and fill slopes as well as failing stream fill and please note the

fallen trees where the soil has eroded out from under them. This site has a massive valley fill,

about 20 to 25 metres high, perched just above a house. This fill is failing through a complex set of

rotational slumps and gullies. There is an under -sized culvert, it is visible in the gully to the right

of the house. It is impressive to see the degree of in stability and the severity of erosion that has

occurred in response to the modest rains experienced since construction.

Again we have multiple active deltas forming from erosion from road material, forming

along the San Juan, associated with ongoing fill slope failures and concentrated road run-offs. You

can see the eroding cut slope above leading to that delta, as they call that fan-shaped piece of

sediment on the lower left of the image.

Three years after road construction across steep inner gorge hi ll slopes we have major fill

slope failures continuing to occur. This slide shows pervasive slope instabilities along Route 1856,

which continue to impact the Rio San Juan. And here, again, large poorly constructed cut slopes

and fill slopes are actively failing, resulting in large volumes of sediment delivery to the San Juan,

Route 1856 in the background there with large, actively forming deltas along the river, delivering

significant quantities of poor sediment to the river. And I should emphasize Mr. President, that

when you see these deltas above water you do not see the rest of the iceberg, as it were,

underwater. So there is a projection of that same delta, perhaps four to six metres, according to

Dr. Kondolf and his colleagues, underwater.

This is another large delta. And significant erosion which results in massive amounts of

sediment delivery to the river.

Thank you all for your kind attention to those images. Mr. President, these images document

invasions of sovereignty and territorial integrity of Nicaragua.

20. Mr. President, Members of the Court, as Mr. Reichler will show, Costa Rica has

indicated that it will resume work on the road very soon. Here ’s what Dr. Kondolf’s report has to

say about this prospect: - 31 -

“If work continues on Rt e 1856, its impact will be devastating to the areas
directly affected and to downstream receiving waters. Already we see extensive,
severe environmental damage, with only ‘normal’ rains. There is no question that
when intense rains associated with tropical storms and hurricanes occur, the damage
will be widespread and severe. These effects will be irreversible in that there will be

no way to recover the prior environmental values and intact ecosystem, nor to reverse
the massive transfers of sediment from uplands to the river and other wetlands. The
land and waters will be permanently altered for the worse, with an environmental
legacy that could be likened the effects of massive mining, such as seen in California
in the mid-19th century or extensive logging such as occurred in the Pacific Northwest
of the US in the 1950s and 1960s. The landscapes are still attempting to recover from

these trau42s, and many important species (notably salmon) have not, and never will
recover.”

21. Mr. President, Members of the Court, resumption of work on the road must be stopped in

order to prevent these “irreversible”  that is, irreparable  environmental effects.

22. Mr. President, in the documents it filed yesterday morning , Costa Rica makes much of

what it holds out as mitigation measures on the road project. Unfortunately, these measures are but

a band-aid on an open wound. They do little if anything to stem the tide of sediment and other

debris flowing into the San Juan. In fact, the measures appear to be d esigned to preserve the

road-bed more than to prevent sedimentation of the river, as Dr. Kondolf observed in his report.

With your permission, Mr. President, I would like to read a rather lengthy pair of quotes from his

report that you will find at tab 7 of your folders:

“Our field observations in October 2013 clearly showed that . . . erosion control

and drainage works have been ineffective in addressing the serious erosion and slope
stability problems. Roughly half of the road above Boca San Carlos has now been
covered in gravel, a technique designed to reduce the rate of surface erosion of the
road. However the fill slopes below the road surface are largely unprotected, and are
being actively eroded by water running off the road.

The most common erosion control measure employed along Rte 1856 has been
black plastic sheeting, but most of this has already failed. Many drainage culverts
appear to be undersized, and we observed one that completely washed out and ended
up in the river. ”

I assume that is the one we have already seen this morning.

“. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

In our field visit of May 2013, we observed some surface and gully erosion
control measures had been installed (since October 2012) at some actively eroding

sites. [Then Dr. Kondolf describes some of these measures] . . . While these
measures may reduce surface and gully erosion from the few treated areas during

42
Kondolf Report, op cit supra, p. 2; emphasis added.
4Ibid., p. 2. - 32 -

small and moderate r ains, they will do nothing to prevent massive failures of fill
prisms [that is the part on the downhill side of the road] and cut slopes with
unfavorable rock type and geologic structural orientation, and associated with poorly

designed and constructed fil l slopes. Moreover, the erosion control measures we
observed were deployed only to mostly protect the road surface ; they did nothing to
safely manage the concentrated runoff from the roads . In fact, we observed one of
these sites immediately after an in tense rain, and we observed road runoff being
directed from a new concrete drain into the fill slope, eroding the fill slope itself,
44
which is the foundation for the road .. .”

23. Mr. President, you now see on your screens figure 4, a photo of Route 1856 from the

San Juan River taken on 22 May 2013 showing a concrete -lined ditch discharging flow into road

45
fill, which is the foundation of the road, as Dr. Kondolf explains . This would seem to make the

sedimentation of the river worse, not better.

24. You now see on your screens [further narrative from slides] an impressive looking

concrete-lined trench leading, apparently under the road, although it looks like it leads to the top of

the road, but let us assume it leads to a culvert passing under the ro ad. Now the larger context of

that picture showing that this trench does nothing to alleviate the erosion of the cut slope above the

road.

25. But, Mr. President, there is more involved here than filling up a river bed with sediment

from a badly- constructed road. There are living things in the river. These are affected by this

sediment.

26. The report of Dr. Kondolf shows that there is a serious risk of irreparable harm to species

and the ecosystem itself from the delivery of coarse and fine sediment into the river from the road.

In addition to his findings already quoted concerning what he describes as the “irreversible”

impacts of work on the road upon ecosystems and the environment, Dr. Kondolf states that:

“[i]ncreased delivery of coarse sedi ment to rivers can result in significant changes to
river processes, causing aggradation [or build -up] of the river channel . . .
Aggradation results in burial of important aquatic habitats and consequent loss of
native species, impacts that have been documented to persist for decades.” 46

44
Kondolf Report, op cit supra, pp. 9-10; emphasis added.
45Ibid., p. 10.
46
Ibid., p. 7. - 33 -

27. Ecological sampling conducted in late May of this year and reported at page 13 of

Dr. Kondolf’s report confirms the “negative ecological effects of sediment eroded from R oute 1856
47
upon the Rio San Juan” .

28. These consequences can be quite serious, and there is a clear, scientifically -based risk

that they will be with respect to the ecosystems of the San Juan. Dr. Kondolf notes that the effects

of the delivery of large quantities of sediment into rivers has been “especially well-document[ed] in

North America . . . where logging roads were once constructed using exactly the same practices we

have document[ed] on Route 1856. (These practices are now outlawed in North America.)”

Dr. Kondolf concludes:

“The increased sediment loads to rivers are documented to have caused the loss
of aquatic vegetation, macroinvertebrates, amphibians, and valued fish species, as well

as degraded water quality. These effects have been docu48nted in multiple sites
around the globe in a wide range of ecosystems.”

29. Mr. President, Nicaragua has a right to ecosystems within its sovereign territory that are

undisturbed by conduct and resulting events in Costa Rica. As Dr. Kondolf’s report demonstrates

on the basis of well -documented experience, this right is subject to a serious and imminent risk of

suffering irreparable prejudice before the Court has given its final decision in the case, all the more

if Costa Rica is permitted now to resume work on the road.

30. And, Mr. President, Members of the Court, it should not be forgotten that the territory

surrounding the road includes more than four different protected areas within both countries.

In 2001, the San Juan River itself was designated a wetland of international importance under the

49
Ramsar Convention , of which we have heard so much from Costa Rica. According to Ramsar,

the San Juan River Wildlife Refuge and the adjoining Indio Maíz Reserve form part of “one of the

two most extensive biological nuclei of the Mesoamerican Biologi cal Corridor” 50. The river’s

wetlands support 303 bird species, 26 mammals, and 23 fish species, in addition to a great diversity

52
46 endangered species in habiting the Refuge, including the rare manatee . Mr. President,

Members of the Court, interim measures are necessary to protect these species from irreparable

harm pending the Court’s judgment in the case.

(c) Nicaragua’s right to receive a transboundary environmental impact assessment on the road

project from Costa Rica

31. Mr. President, allow me now to turn to a third right of Nicaragua whose continuing

breach threatens irreparable prejudice, and I refer here to the right to receive a transboundary

environmental impact assessment on the road project from Costa Rica.

32. Mr. President, preparation of an environmental impact assessment, or EIA, prior to

beginning work on a project that may have a significant impact on the environment is now common

practice internationally. The domestic laws of many, if not most, States require that an EIA be

prepared, and this is true of Costa Rica. Unfortunately, one was not prepared prior to the

commencement of work on the project, which was embarked upon without any plans or

preparatory studies, pursuant to the emergency decree referred to by the Agent. What was the

supposed emergency? The cleaning of a small caño by Nicaraguan labourers using hand tools,

work that is now the subject of the Certain Activities case. What is the relationship of the road to

the caño cleaning? That is far from clear, especially since the road stops at the Colorado branch of

the San Juan River, well short of the “area in dispute” in the Certain Activities case.

33. Thus we have, Mr. President, a very curious situation: Costa Rica, which holds itself out

as a paragon of environmentalism, responds to Nicaragua ’s actions along a narrow strip of some

1,500 m in the vicinity of Harbor Head Lagoon 53 by despoiling some 160 km of its own territory,

54
120 of which are along the Rio San Juan . And it does this without any prior study, let alone

notification of Nicaragua.

51
See MARENA, The San Juan River Wildlife Refuge Management Plan, 2005, p. 37 (Ann. 40 to the Rejoinder
of Nicaragua (RN) in the Dispute regarding Navigational and Related Rights (Costa Riv. Nicaragua), 15 July 2008);
see also pp. 119-128 (ibid., Ann. 1) for a table of the numerous animal species found in the San Juan River Wildlife
Refuge.

53CMN (Certain Activities case), Vol. I, p. 44, para. 2.60.
54
See MN, Vol. I, p. 150, para. 5.3. - 35 -

34. If preparation of a domestic EIA is advisable 55, preparation of a transboundary EIA is

now required by customary international law, as this Court is well aware, because you made this

obligation clear in the Pulp Mills case when you said,

“it may now be considered a requirement under general international law to undertake

an environmental impact assessment where there is a risk that the proposed industrial
activity may have a significant adverse impact in a transboundary context, in
particular, on a shared resource” . 56

35. In fact, Costa Rica itself has insisted on this requirement in the Certain Activities case, in

which its Memorial underscores “[t]he necessity of a proper environmental impact assessment in

order to prevent or minimize transboundary harm”, emphasizing that this “is now a well-recognized

57
requirement of general international law . . .” .

36. Costa Rica howeve r breached the requirement to prepare a transboundary EIA and thus

breached Nicaragua’s rights. Among the rights of Nicaragua that Costa Rica has breached by this

failure are the rights to notification and consultation concerning the potential transboundary impact

of the proposed activity 58. Without this information, Nicaragua is left entirely in the dark about

Costa Rica’s intentions, and cannot prepare to protect itself, to the extent that this is at all possible.

This is a continuing breach and a ripe subject of a provisional measures order. At the very least,

Costa Rica must be ordered to prepare a proper transboundary EIA and share it with Nicaragua

before it is allowed to resume any road construction activities.

Conclusion

37. Mr. President, Member s of the Court, it is easy to di scount the seriousness of

Costa Rica’s conduct and its effects on Nicaragua because of the human tendency to think of rivers

as “a convenient sink into which to dump wastes” 59, in the words of a United Nations report, which

55Principle 17 of the Rio Declarati on requires such domestic EIAs : “Environmental impact assessment, as a
national instrument, shall be undertaken . . .” (Rio Declaration on Environment and Development, adopted by the United
Nations Conference on Environment and Development, Rio de Janeiro, 14 June 1992, 31 ILM 874 (1992), Principle 17;
emphasis added). For a full discussion of Costa Rica’s actions in this regard on the national level, see CMCertain

humans have done, unfortunately, “[f]or millennia” . It is not hard to understand why: you put

something in a river, and it goes away, as if by magic.

38. The problem for Nicaragua is twofold: first, the river is indisputably Nicaragua’s

territory. If we were dealing with a land boundary, it would be as if Costa Rica sent 5,000 dump

trucks full of sediment  5,000 being the number of trucks it would take to carry the average

quantity of sediment Dr. Kondolf’s team estimates to be delivered into the ri ver annually 61  and

had these trucks dump this waste over the border into and onto Nicaraguan land. No country or

court would tolerate this.

39. Yet when the incursion is invisible, as compared with dumping across a land boundary,

there was historicall y no comparable sense of urgency or outrage. Our modern understanding of

the dangers of water pollution has changed this. But conceptually, the problem of the “wet

trespass” persists: a territorial violation by dumping into a river somehow may not seem as grave

as the same violation on land, because the material is hidden by the very water it is polluting.

Nicaragua trusts that the Court will recognize the violation as being equally serious, if not more so

due to the multiple ecosystems affected.

40. The second aspect of the problem is precisely that where Nicaragua is concerned, the

waste does not “go away”. It settles in the already slow -moving Lower San Juan River, creating

further impediments to navigation, causing irreparable harm to ecosystems, a nd further occluding

the mouth of the river.

41. Nicaragua trusts that the Court will recognize the violations of its sovereignty and

territorial integrity that have occurred, are occurring, and  particularly with Costa Rica’s

imminent resumption of work on the road, as Mr. Reichler will presently show  will occur, and

that the Court will see fit to grant its request for provisional measures to protect its river, its

sovereign territory, from further irreparable prejudice. Nicaragua’s territorial integr ity has been,

60Ibid.
61
As indicated earlier, Dr. Kondolf’s team estimates that between 87,000 and 109,000 cubic meters of sediment
are delivered into the river annually by the road project under “normal” precipitation conditions. The typical dump truck
holds a maximum of 20 cubic meters of material (MN, para. 3.79). Thus it would take 5,000 fully -loaded dump trucks to
haul some 100,000 cubic meters of sediment. - 37 -

and continues to be violated by Costa Rica. Nicaragua relies on the Court to bring this continuing

violation to a stop, at least pending its judgment in the case.

42. Mr. President, distinguished Members of the Court, that concludes my inte rvention this

morning. Thank you for your kind attention. Mr. President, I would be grateful if you would now

call my friend and colleague Mr. Reichler to come to the podium, perhaps after a break.

The PRESIDENT: Thank you very much, Professor McCaffre y. The Court will now take a

15-minute break and after that I shall give the floor to Mr. Reichler. For planning purposes, in

view of the few minutes I took to open the proceedings, Nicaragua may take a few minutes after

1 o’clock, if needed; certainly not beyond 10 minutes past 1 p.m.

The sitting is adjourned.

The Court adjourned from 11.25 a.m. to 11.40 a.m.

The PRESIDENT: Please be seated. Mr. Reichler, it is now your turn. You have the floor,

Sir.

Mr. REICHLER:

THE URGENT NEED FOR THE MEASURES REQUESTED BY N ICARAGUA

1. Mr. President, Members of the Court, good morning. I will speak today about urgency,

specifically: why the need for the provisional measures Nicaragua has requested is urgent.

2. The Court may be asking itself : if the need for these measures is so urgent, why didn ’t

Nicaragua ask for them earlier ? Nicaragua has had almost two years to do so . It filed its

Application in December 2011. As the Application stated, construction of the road had already

begun, and it had already begun to harm the San Juan River, in violation of Nicaragua ’s sovereign

rights. Nicaragua expressly reserved the right to request provisional measures to stop further

construction, especially if Costa Rica continued to refuse to inform Nicaragua about it s activities,

refused to consult with it about possible transboundary harm to the r iver and its environs, and

refused to furnish it with an Environmental Impact Assessment addressed to that issue. - 38 -

3. Nearly two years have passed since the Application was filed. Throughout this entire

period, Costa Rica has never informed Nicaragua about any of its road construction plans or

activities, never consulted with Nicaragua about ways to mitigate harm to the river or its environs,

and never furnished Nicaragua with an Environmental Impact Assessment. And, during this entire

period, Costa Rica has caused significant volumes of sediments and road construction debris to

continue to be deposited into the river.

4. So why has Nicaragua chosen now to request provisio nal measures? What makes them

urgent now?

5. The answer is this: first, since filing its Application Nicaragua has exhausted every other

avenue available to it, before a variety of international organizations and forums, in its effort to

cause Costa Ric a to comply with its international obligations in regard to notice, consultation,

Environmental Impact Assessment, and the avoidance of harm to Nicaragua ’s sovereign territory.

As Ambassador Argüello explained, Nicaragua had hoped that these efforts would avoid the need

to impose on the Court the burden of holding these hearings . But they have all been unsuccessful,

leaving the Court as Nicaragua’s last recourse to protect its sovereign rights, and to prevent further

harm to the San Juan River.

6. Second , after two years of ongoing discharges into the river, the sediments and

construction debris are accumulating to dangerous levels that have already harmed the river

irreparably, and threaten to cause further irreparable harm if they are allowed to continu e.

Professor McCaffrey has explained this.

7. Third, and this is what most underscores the urgency and immediacy of Nicaragua ’s

request, Costa Rica has recently announced that it will redouble its road construction activities

before the end of this year, so that it can complete construction between October and December of

2014, which is very likely before the Court will have had a chance to issue its judgment in this

case 62.

8. Mr. President, it had appeared that Costa Rica had decided not to complete con struction of

the road. In fact, in the middle of 2012, Costa Rica suspended all new construction activities on the

road . At the time, only the first phase of construction had been completed. None of the five

sections was finished, and work on some of them had not even started. Since then, for more than a

year, there has been no significant new road construction, only efforts to remediate or mitigate the

harmful consequences of the first phase of construction activities . C ontracts to complete

construction of the road were cancelled 64. The need for provisional measures, therefore, was less

urgent.

9. Until now, that is. Costa Rica has now announced that it is resuming full -scale

65
construction, and that it will complete the project by the end of 2014 . Here is the construction

66
schedule publicly announced by Minister of Public Works Dr. Pedro Luis Castro Fernandez .

[Graphic]. These are slides from the Minister’s powerpoint presentation, available on the Internet .

They are at tab 10 of your judges’ folder, in both the original Spanish and English translation.

According to the schedule, Section 1 is to be constructed between September 2013 and

October 2014; Section 2, the construction is to be completed between September 2013 and

October 2014; Sectio n 3, construction is to be completed by December 2014; Section 4 by

December 2014 and Section 5 by October 2014.

10. There appears to have been some delay in restarting the works, resulting from

administrative challenges to the process by which contracts for road design and construction were

awarded, pushing the start-date for the “construction phase” beyond September 67. But Costa Rica

has very recently publicly reiterated its commitment to resume construction activities before the

end of this year; that is, by next month at the latest, and to complete the project by the end of next

year .8

11. It is the imminence of Costa Rica ’s resumption of new road construction activities that

gives particular urgency to Nicaragua’ s Request. Professor McCaffrey has explained that

irreparable harm to Nicaragua’ s rights and the San Juan River has already been  and is still

being  caused by Costa Rica’s hasty and slip-shod road construction in 2011 and early 2012, as

well as the unfinished and unprotected conditions in which the partially performed works were left

for the past year and a half. Even more importantly for present purposes, the evidence leaves little

doubt that even greater irreparable harm to the river and its environs is likely if construction is

allowed to resume. That new construction is now imminent . It will go forward, very soon, if

provisional measures are not ordered. Costa Rica has given Nicaragua no notice about its start -up

plans. But its senior officials have spoken loudly and clearly about them to their domestic

audience.

12. Costa Rica did not stop constructing the road in mid- 2012 because of Nicaragua ’s

protest, or because of the Application in this case . The reasons were given in public statements by

Costa Rica’s highest officials, inc luding its President. Two reasons were stated . First, the funds

appropriated for the project had been exhausted . It could not be completed without additional

69
financing . Second, Costa Rica announced that the first phase of the project had been plagued by

corruption 70. The Minister of Public Works and Transport, who was in charge of the project, was

71 72
forced to resign . Criminal indictments were issued against others .

13. I point this out not to embarrass Costa Rica, which deserves credit for exposing a nd

condemning the corruption of its officials, but because of the implications for the state of the works

at the time they were suspended . With contracts being inappropriately issued, and contractors

buying their way out of proper management and supervisi on of their performance, it is not

surprising that the road was constructed so shoddily, and without regard for environmental risks, as

shown by Professor McCaffrey, and as fully elaborated in Nicaragua’s Memorial.

14. Nicaragua was sufficiently troubled by the ongoing harm to the river caused by the

partially competed works, and by Costa Rica’s continuing refusal to give notice about future plans

for the road, or to provide Nicaragua with a transboundary EIA, that it wrote to the Court on

19 December 2012 suggesting that the Court might wish proprio motu to indicate provisional

measures to protect the San Juan River from further harms. Nicaragua did not then wish to burden

the Court with oral hearings, at a time when new construction activities had been suspended. Costa

Rica assured the Court in June 2013 that it was then engaged only in remediating problems from

73
earlier construction, not in any new construction .

15. But all that has now changed. We are in a new situation . Costa Rica has publicly

announced that it will resume road construction before the end of the year, that is, in a matter of

74
weeks . Maybe sooner . Only Costa Rica knows for sure . It still refuses to provide any

information to Nicaragua about its activities, to consult about transboundary harm and what can be

done to avoid it, or to produce an EIA addressed to the harms and risks posed by the road to the

San Juan River. Nicaragua is forced to rely exclusively on public statements by senior Costa Rican

officials, as reported in the media and on government websites. But these have been clear enough .

The resumption of road construction activities is imminent . And so is the aggravation of the

irreparable harm to the San Juan River and its environs that will inevitably result.

16. Mr. President, let me be clear about what Nicaragua seeks to prevent . It does not ask the

Court to stop Costa Rica from taking appropriate steps to remediate the problems c aused by its

7Written Observations on the Request by Nicaragua for the Modification of the Court’s Order of 8 March 2011
on Provisional Measures in the Case Concerning Certain Activities Carried out by Nicaragua in the Border Area, p. 16,
para. 40 (20 June 2013).

7“Action Plan for Completion”; President of Costa Rica, Government Strong on Comprehensive Development of
the Boundary Strip Guarantees Conclusion of Route 1856, Mar. 2013 (NPM-2). - 42 -

earlier construction activities . To the contrary, based on Dr. Kondolf’s analysis, there are specific

remediation measures that should be undertaken immediately to prevent further irreparable harm to

Nicaragua. These are the object of the second set of measures requested by Nicaragua, which

Professor Pellet will discuss short ly. What Nicaragua seeks to prevent is a resumption of new

construction activities, aimed at building or completing the road. This is the substance of the third

provisional measure that has been requested.

17. Only by preventing these activities now, be fore they restart, can the threatened

aggravation of the environmental and other harm s to the river  and to Nicaragua ’s rights in

regard to it  be prevented. The situation is urgent because the threat to Nicaragua ’s rights is

imminent, and the harm cannot be undone by the Court ’s final judgment. By that time, the road

construction activities will have been completed . Costa Rica itself says that its goal is to complete

the road between October and December 2014 7. We still don ’t know whether there will be a

second round of written pleadings in this case. But even if there is not, the Court has yet to set oral

hearings and it is unlikely that the Court could hold them and issue its judgment before the road is

completed. By that time, it will be a fait a ccompli. The need for provisional measures is urgent

because irreparable harm to the river has already occurred, and additional and even greater

irreparable harm is imminent, and cannot be prevented or reversed by the Court’s judgment.

18. In its Order of 8 March 2011, the Court addressed the meaning of “urgency” in the

context of a request for provisional measures : “the power of the Court to indicate provisional

measures will be exercised only if there is urgency, in the sense that there is a real and i mminent

risk that irreparable prejudice may be caused to the rights in dispute before the Court has given its
76
final decision” . Mr. President, that is the situation we have here. The risk of further irreparable

prejudice, in the form of violation of Nica ragua’s sovereignty and harm to the San Juan River and

its protected environment, is real. It is imminent, as well, because Costa Rica is planning to resume

its harmful activities imminently . And the harm to Nicaragua ’s rights, in the form of continued

75“Action Plan for Completion”.

construction of the road until its completion next year, will be caused before the Court has given its

final decision.

19. In the Nuclear Tests case New Zealand demonstrated that irreparable harm was real and

imminent because France had already carried ou t a series of atmospheric tests, had refused to give

assurances that it would conduct no further tests, and had made official pronouncements from

78
which it appeared that further tests were envis ioned . The Court indicated provisional measures,

finding that there was “an immediate possibility of a further . . . test being carried out by France in

the Pacific” and that “for the purpose of the present proceedings it suffices to observe that

information submitted to the Court . . . does not exclude the possibil ity that damage to New

79
Zealand might be shown to be caused” .

20. In the present case, Costa Rica has likewise refused to give assurances that it will engage

no further in its harmful activity. To the contrary, it has publicly announced that it will resume

construction of the road as soon as possible, and that it will complete the project before the Court

has a chance to give its final decision.

80
21. The latter point is critical . In the Great Belt case , Denmark argued that there was no

urgency to Finland’s request for provisional measures because “according to the planned schedule

for construction . . . no physical hindrance for the passage through the Great Belt [would] occur

before the end of 1994” and “by that time the case could have been finally decided by the Court” 81.

It was not all construction by Denmark that posed a risk of irreparable harm to Finland, only that

portion of the works that would have obstructed passage . The Court accepted Denmark ’s

assurances that there would be no physical obstr uction before the end of 1994. On that basis, it

concluded that “the proceedings on the merits in the present case would, in the normal course, be

completed before that time,” and therefore, that Finland had failed to show that “the right claimed

will be infringed by construction work during the pendency of the proceedings” 82. We are in the

77

opposite situation here. Any construction of the road by Costa Rica will cause still more harm to

the river, and will therefore aggravate the ongoing infringement of N icaragua’s rights during the

pendency of these proceedings.

22. The Pulp Mills case 83also offers useful lessons . The Court will recall that it denied

Argentina’s request for provisional measures to stop Uruguay from commissioning two paper pulp

mills on the Uruguay River. At the time, Uruguay had authorized construction, but not operation

84
of the mills, which would not commence, even if authorized, for another two years . And

Argentina acknowledged that there was no irreparable harm from construction alo ne, only from

85
operation . Thus, irreparable harm, if any, was far from imminent.

23. Moreover, Uruguay had provided Argentina not only with its own e nvironmental impact

assessment, but also with two comprehensive studies done at the behest of the World Bank, which

showed that the two mills could be safely operated without harming the river or its environs 8.

Uruguay also pledged to conduct a further EIA, and subject the mills to additional environmental

87
conditions recommended by the World Bank, prior to authorizing their operation . Finally,

Uruguay agreed not to present Argentina or the Court with a fait accompli. It gave an undertaking

to tear down the plants, or convert them to another use, if the Court determined in its final

Judgment that the plants should not be operated 8. The Court thus found that “their construction at

89
the current site cannot be deemed to create a fait accompli” , and that provisional measures were

not necessary.

24. The Court distinguished that situation from the one in which construction itself cause s

the irreparable harm:

“if it is established that the construction of works involves an infringement of a legal
right, the possibility cannot and should not be excluded a priori of a judicial finding
that such works must not be continued or must be modified or dismantled.” 90

25. Mr. President that is the situation we have here. In this case, unlike in Pulp Mills , the

irreparable harm comes from the construction of the works  that is the building of the road  as

much as, if not more than, by its use.

26. Nicaragua, unlike Argentina, cannot sit tight during the construction phase and hope that

the operation of the facility is unharmful . By that time, still more irreparable harm will have been

done to the river, and still more prejudice will have been caused to Nicaragua’s rights.

27. Also, unlike Argentina, Nicaragua has not been given an undertaking by Costa Rica that

it will un-build the road at the end of the day if the Court determines it is harmful to the river . Nor

would such an undertaking do any good here. The major irreparable damage, from construction of

the road, will already have been done . Un -building it would make things even worse .

Deconstruction of the road would be just as harmful to the river, in terms of massive deposit of

sediments and other pollutants, as constructing it . Only the measures recommended by

Dr. Kondolf and his team, and requested by Nicaragua, would stand any chance of protecting the

river from the sediment and debris that are constantlyentering the river from the road.

28. In this case, unlike Pulp Mills , there is a grave risk of irreparable environmental harm,

not only to the river, but to the protected wetlands on both sides, the importance and vulnerability

of which Costa Rica itself has highlighted. We take Costa Rica at its word in regard to its interest

in protecting these wetlands, at the mouth of the San Juan River, from irreparable harm . Three

weeks ago, Costa Rica’s expert, Dr. Thorne, warned that if enough silt were deposited at the mouth

of the San Juan River, there would be “a significant risk that it would close entirely at times of low

runoff during the next and subsequent dry seasons” 91. According to Dr. Kondolf, that is the same

risk that is exacerbated by Costa Rica’ s road construction activities, and the sediments they drive

into the river, which are carried down to the mouth where they accumulate.

Nicaragua in the Border Area (10 Oct. 2013), p. 6, para. 4.7. - 46 -

29. Mr. President, Costa Rica, as well as Nicaragua, would appear to gain from measures

that reduce the sediment load of the river, and enable it to continue to supply fresh and clean water

to the wetlands, and the flora and fauna that inhabit it, on both banks of the Lower San Juan near its

mouth. Keeping the river from silting up also serves Costa Rica ’s interests in bei ng able to

exercise its right to navigate on the river for commercial purposes. How then would Costa Rica be

harmed by provisional measures requiring it to refrain from further road construction activities

pending the issuance of the Court’s Judgment?

30. To answer this question, we have to hear from Costa Rica on why it is building the road

in the first place. Nicaragua offers no conjecture here. Again, we take Costa Rica at its own word .

According to the President of Costa Rica, and various senior government officials, there is one

purpose for the construction of this road : national defence 92. President Chinchilla has repeatedly

stated that the road is necessary to protect Costa Rica  specifically to protect the disputed area

that is the subject of the Certain Activities case  against a “military invasion” by Nicaragua 93.

The President, and other officials of her government, characterized Nicaragua ’s clearing and

dredging activities in 2010, in regard to the first caño in the disputed area, expressly as a “military

invasion” of Costa Rican territory 9. Route 1856 has been justified as a direct and immediate

response to th is so-called military invasion. Its construction was quickly authorized under an

emergency decree as vital to the protection of Co sta Rica’s territorial integrity and national

95
security . Costa Rica has not sought to justify it on the basis of economic development,

commercial activity, or civilian transportation or communication needs. Its raison d’être is to

facilitate the movement of Costa Rican security personnel to the region, to safeguard against

potential Nicaraguan military encroachments upon the disputed area, and to evacuate civilians in

96
case of a Nicaraguan armed attack . [Graphic] Here, in its own words, is how Costa Rica

explained the purpose of the road as recently as May 2013. This is from a document, produced in

its entirety at t ab 11 of your judges’ folder, both in the Spanish original and English translation.

The document bears the heading : “Position of the Gover nment of the Republic in Relation to

Route 1856.”

“Costa Rica assumed defense of its national sovereigntyand territorial integrity
as a consequence of acts carried out by Nicaragua in the northern borderline area.

That country is the one that militarily invaded Costa Rican territory and keeps
threatening us with a scale-up of the conflict.

At that time, our policemen did not have access to the area in conflict by land,
they could not access it by water, and it was very difficult to do so by air. This

obliged us to take urgent and immediate actions to allow them access to the area. In
addition, the risk of an escalated conflict could result in the displacement of borderline
communities, which required a road to facilitate civil evacuation actions, mobilization
and defense.” 97

31. There are, then, two competing rights at issue in these proceedings . One is Nicaragua’ s

right to protection against harm to the San Juan River and its environment resulting from

Costa Rica’s road-building activities. The other is Costa Rica’s right to construct a road in its own

territory. These rights did not have to come into conflict, if Costa Rica had constructed a road after

careful preparation of plans, following professional engineering standards, and observing its

international obligations vis-à-vis Nicaragua. But Costa Rica did not do any of this, and a dispute

has resulted. The Court will ultimately decide which of these rights prevails over the other, or

whether they can be balanced in a manner that is equitable to both Parties . For present purposes,

however, only one of these rights is threatened with irreparable harm. And that is Nicaragua’s right

to protection of its sovereignty and territorial integrity, and protection of the river from silting up,

from pollution and from other environmental harm . Professor McCaffrey has shown how that

harm is irreparable, and I have explained why it is imminent — such that protective measures are

required as a matter of urgency.

32. The same cannot be said of Costa Rica’s right. Postponing the resumption of

construction activities for another year or so, until the Court issues its judgment, would do no

96

9Ibid., paras. 1-2. - 48 -

irreparable harm to Costa Rica’s right. Costa Rica has already delayed construction for more than

a year due to its own internal difficulties . It has not been the victim of a Nicaraguan military

invasion during this period. Nor is any such invasion likely, or even, to be blunt, remotely

imaginable. Costa Rica’ s interest in having a road to protect its interests in the disputed area

against a Nicaraguan attack is already protected by the Court ’s Order of 8 March 2011, which

requires Nicaragua to refrain from sending military personnel into the disputed area.

33. Mr. President, even uttering the words “Nicaraguan military invasion” or “Nicaraguan

attack” seems surreal. It is difficult to believe that Costa Rica takes this delusion seriously . Yet,

this is what Costa Rica’s most senior officials, including their President, repeatedly invoke as the

reason for constructing H ighway 1856, and the reason for rushing to complete it . This does not

mean, however, that there is any basis for the Court to take it seriously . The evidence shows that it

need not.

34. The day after the Court issued its Order — as the Court is aware — the Commander of

the Nicaraguan a rmy for the southern region issued his own order that explicitly forbade all

military personnel from entering the area 98. This order was issued pursuant Presidential Decree

No. 79 of the year 2009, which gave the a rmy commander authority over all military and civilian

governmental activities and personnel in the remote area of the L ower San Juan River. For at least

two-and-a-half years, until August 2013, Nicaraguan military and civilian personnel faithfully

complied with this order and, more importantly, with the Order of the Court. The Court has been

informed of Mr. Pastora’s activities in the area during late August and September, which

President Ortega immediately put an end to , as soon as he learned of them . Costa Rica has

complained of no other intrusions into the disputed area by Nicaraguan military or governmental

personnel, and there have been none . Nicaragua remains subject to the Court ’s Order, and has

reiterated to the Court its commitment to comply with it. I n short, Costa Rica has a better means

than Route 1856 of protecting itself from the purely hypothetical incursion of Nicaraguan military

forces into the disputed area. It has an Order from the Court.

9Order No. 005 from the Chief of the South Military Detachment for compliance of order from the Chief of S taff
regarding the implementation of special measures based on provisional measures of protection ordered by the
International Court of Justice and ma intenance of the anti -drug trafficking plan, rural, security plan and presidential
Decree 79/2009 at the San Juan de Nicaragua directorateMarch 2011 (CMN, Ann. 36, in the Dispute Concerning
Certain Activities Carried out by Nicaragua in the Border Area (Costa Rica v. Nicaragua)). - 49 -

35. I should also point out another reason for the la ck of urgency, if not lack of need itself,

for the completion of this road. [Graphic] This is CostaRica’s map, from its Written Observations

on the Admissibility of Nicaragua’s Counter -Claims, in the Certain Activities case . It is at tab 12

of your judges’ folder. The disputed area is indicated in the upper right quadrant, near the very top

of the page. T he road is shown as a green line, in the lower left quadrant. As depicted here, t he

road ends more than 25 km from the disputed area . It is a long 25 km. There is no way to get by

land from the end of the road to the disputed area . Nor does Costa Rica have the right to send its

security forces to the disputed area via the river . It would have to build a bridge across the

Colorado branch of the San Juan, which is not included in their road construction project, and even

then it would have to build a road across more than 20 km of impassable swampland that also

happens to be a protected Ramsar site. This is truly, literally, a road to nowhere . It is difficult to

imagine how it would be of use to Costa Rica in self -defence against a Nicaraguan military

invasion of the disputed area, even if one were willing to suspend disbelief long enough to imagine

such a possibility.

36. In the Certain Activities case, the Court will ultimately decide whether the disputed area

belongs to Nicaragua or to Costa Rica . If it decides in favour of Nicaragua, then Costa Rica can

have no interest in protecting that area against a so -called Nicaraguan “invasion”. If it d ecides in

favour of Costa Rica, then Nicaragua will no longer have a claim to the area, and will be bound by

the Court’s judgment, as well as the U nited Nations and OAS Charters and general international

law, to respect Costa Rica’ s sovereignty and territo rial integrity. Nicaragua has already told the

Court it would abide by its Judgment, whatever it may be, and there is no reason to doubt this

undertaking.

37. Thus, Costa Rica ’s right to protect itself by building a road on its territory is not

threatened by the provisional measures requested by Nicaragua. If Nicaragua’s request is granted,

Costa Rica’s right will not be irreparably harmed . In fact, it w ill not be harmed at all, given the

stated purpose of the road. Costa Rica’s security interests are already protected by an Order of the

Court. Should a mythical Nicaraguan military in cursion occur, or should Costa Rica have grounds

for believing that it might, it can come back to the Court for further protection . It has shown no

hesitancy about coming here in the past. - 50 -

38. In conclusion, it is Nicaragua’s right  and only Nicaragua’s right  that is threatened

with irreparable harm. The threat is grave, and it is imminent . The harm is such that it could not

be prevented or reversed by the Court ’s final judgment. The Court’s jurisprudence makes clear

that, when considering the indication of provisional measures, the Court takes the interests of both

parties into account and seeks to ensure that neither party’s right in issue is subjected to irreparable

prejudice pending the final j udgment. Mr. President, Costa Rica ’s right in issue  to protect its

claimed territory from military incursion by Nicaragua by construction of this roa has already

been protected pendente lite by the Court. It is Nicaragua’s right that requires protection now. The

measures requested by Nicaragua would protect that right, without diminishing Costa Rica ’s. As

Professor Pellet will now explain, those measures meet the well -known standards for the issuance

of provisional measures, and should be indicated by the Court.

Mr. President, Members of the Court, I thank you for your kind and courteous attention and

ask that you call my distinguished colleague Professor Pellet to the podium.

The PRESIDENT: Thank you , Mr. Reichler. Je passe la parole à M. le professeur

Alain Pellet. Vous avez la parole, Monsieur.

M. PELLET :

L ES MESURES DEMANDÉES PAR LE N ICARAGUA

1. Merci, Monsieur le président . Monsieur le président, j’ai bien noté que je pouvais

continuer jusqu’à 13 heures 10, cela m’évitera d’engager avec les interprètes une course qu’ils

risqueraient de ne pas gagner.

Monsieur le président, Mesdames et Messieurs de la Cour, il m’appartient de détailler les

mesures demandées par le Nicaragua et d’en établir le bien -fondé (II.). Auparavant, je souhaite

dire quelques mots sur les relations qui peuvent exister entre nos propres demandes et celles dont le

Costa Rica vous a saisis il y a trois semaines (I.). - 51 -

I. Les relations entre les mesures demandées par le Nicaragua et

par le Costa Rica

2. Monsieur le président, comme la Cour l’a expliqué dans ses ordonnances du 17 avril2013,

les deux affaires dont le Costa Rica d’abord, le Nicaragua ensuite, l’ont saisie, sont indissociables.

3. Il reste qu’elles demeurent des affaires distinctes en ceci au moins que celle dont le

Nicaragua vous a saisis, l’affaire de la route 1856, concerne des problèmes de beaucoup plus

grande ampleur  aussi bien géographiquement que matériellement  que ceux liés à la parcelle

frontalière contestée . Dès lors, bien qu’il soit légitime, tant pour la Cour que pour les Parties, de

tenir compte du contexte commun aux deux affaires et, à mon sens, que vous soyez parfaitement en

droit, Mesdames et Messieurs de la Cour, de vous prononcer par une ordonnanc e commune sur les

deux demandes en indication de mesures conservatoires, il convient certainement que vous

appréciez leur bien-fondé individuellement et de manière distincte.

4. Il est fréquemment arrivé, dans le passé, que les deux Parties à un différend porté devant

la Cour aient formulé des demandes croisées en indication de mesures conservatoires. Je pense par

exemple à l’affaire Burkina/Mali 100, à celle du Génocide 101ou encore à Cameroun c. Nigeria 10. Et

c’est aussi ce que nous avons voulu faire dans le cadre du présent différend après que le Costa Rica

vous a saisis d’un incident, qu’il eût pourtant été facile de résoudre par la voie diplomatique.

5. Il nous a semblé que cette «contre -demande», si l’on veut, était justifiée car, en vous

saisissant de l ’incident que je viens de mentionner  aussi regrettable qu’il pût paraître  le

Costa Rica tentait de détourner l’attention des activités polluantes de grande ampleur qu’il mène ou

prévoit de mener à nouveau, incessamment , sur le San Juan, activités qui constituent une menace,

autrement plus grave, à la navigabilité et à l’environnement du fleuve. Pour reprendre une formule

que vous aviez utilisée dans votre ordonnance de 1997 relative aux demandes reconventionnelles

dans l’affaire du Génocide , les deux demandes costa -ricienne et nicaraguayenne relèvent d’«un

même ensemble factuel complexe» 103. Il n’y a donc rien d’incongru à ce que la Cour soit appelée à

examiner deux demandes en indication de mesures conservatoires introduites successivement par

les deux Parties à des affaires que vous avez jointes.

6. Ceci étant, nous le reconnaissons bien volontiers, les délais étaient fort courts et il est

compréhensible que, dans sa sagesse, la Cour ait décidé de dissocier la demande du Costa Rica, qui

nous a réunis dans ce grand hall de justice il y a trois semaines, de celle que nous avons formulée à

notre tour.

7. Outre les considérations pratiques qui suffisent à la justifier, cette dissociation a l’avantage

de lever l’ambiguïté qui avait marqué le précédent de mai dernier. Je me permets de rappeler qu’à

cette occasion le Costa Rica, fidèle à sa stratégie du harassement de la Cour par mesures

conservatoires interposées, vous avait priés, Mesdames et Messieurs les juges, de modifier votre

ordonnance en indication de mesures conservatoires du 8 mars 2011, ce à quoi le Nicaragua avait

répondu par une demande modificatrice du même type. En même temps que vous rejetiez la

demande costa- ricienne, vous avez, dans les motifs de votre ordonnance du 16 juillet dernier,

considéré que :

«27. la demande du Nicaragua tendant à ce que l’ordonnance du 8 mars 2011
soit modifiée ou adaptée [était] sans rapport avec la situation considérée dans cette

ordonnance»,

et que :

«même si la situation invoquée dans l’affaire Nicaragua c. Co sta Rica justifiait

l’indication de mesures conservatoires, la voie appropriée pour ce faire ne saurait être 104
la modification de l’ordonnance rendue dans l’affaire Costa Rica c. Nicaragua» .

8. La dissociation que vous avez opérée 105permet, je crois, de clarifier les choses : certes,

notre demande en indication de mesures conservatoires est liée au même contexte factuel que l’était

celle du Costa Rica ; mais il s’agit d’une demande autonome portant sur le volet Nicaragua

Law 10, l’une d’entre vous donnait ce sage conseil aux avocats se présentant devant vous : «ne dites

jamais : «comme l’a dit mon confrère X ou Y...»». Je suis bien conscient que ce n’est pas de la

bonne plaidoirie et que les rappels de ce genre ne sont, en principe, pas de mise : votre écoute est,

bien sûr, attentive... Mais je me permets de penser que la formule est tolérable si elle est suivie

par : «ceci me dispense d’y revenir». Je dirais donc : «comme l’ont montré de manière fort

convaincante mes collègues et amis, Steve McCaffrey et Paul Reichler», les agissements du

Costa Rica risquent de causer de manière imminente  et, à vrai dire, causent d’ores et déjà  un

préjudice irréparable mettant en péril les droits d u Nicaragua en cause dans l’affaire de la
o
construction de la route n 1856 ; «il n’est donc pas nécessaire que j’y revienne».

11. Cela signifie que, globalement, les deux conditions de fond qui doivent être réunies pour

que vous indiquiez des mesures cons ervatoires sont remplies. Je vais m’employer maintenant à

montrer spécifiquement que ces circonstances appellent plus précisément les mesures provisoires

que le Nicaragua vous a priés de bien vouloir indiquer  et je me réfère à la lettre de l’agent

107 o
du Nicaragua au greffier de la Cour du 11 octobre 2013 ; elle se trouve sous l’onglet n 13 de

votre dossier.

1. La première mesure conservatoire demandée par le Nicaragua

12. Aux termes de sa première demande, le Nicaragua prie la Cour de décider «that

Costa Rica immediately and unconditionally provides Nicaragua with the Environmental Impact

Assessment Study and all technical reports and assessments on the measures necessary to m itigate

significant environmental harm to the River ». Ceci, Monsieur le président, est la première des

mesures indispensables pour préserver les droits du Nicaragua, celle qui conditionne l’efficacité de

toutes les autres.

13. Le Nicaragua a justifié la nécessité d’une telle étude d’impact sur l’environnement , une

(«EIE»), dès sa requête introductive d’instance. Dès cette première étape, il avait demandé

«à la Cour de bien vouloir exercer le pouvoir que lui confère son Statut d’ordonner
au Costa Rica de produire le document en question».

Et nous avions ajouté :

«En tout état de cause, et surtout si cette demande ne donne aucun résultat,
le Nicaragua se réserve le droit de demander formellement l’indication de mesures

conservatoires sur la base de l’artic le 41 du Statut et des procédures pertinentes
prévues aux articles 73 et suivants du Règlement de la Cour.» 108

C’est ce à quoi vise la première demande du Nicaragua, puisque, jusqu’à présent, la Cour n’a pas

donné suite à celle qu’il avait formulée dans sa r equête et sur laquelle son agent avait à nouveau

appelé son attention dans sa lettre au greffier du 19 décembre 2012 soumettant notre mémoire 10.

14. De même, dans le mémoire en question, le Nicaragua a établi que le Costa Rica ne

pouvait écarter d’un rever s de la main l’obligation d’établir une étude d’impact sur

l’environnement et de lui en communiquer le résultat 11, et il en a conclu que le Costa Rica était

dans l’obligation

«Not to continue or undertake any future development in the area without an
appropriate transboundary Environmental Impact Assessment and that this assessment
must be presented in a timely fashion to Nicaragua for its analysis and reaction.» 111

15. Il est clair que le Nicaragua a donc toujours présenté l’établissement et la communicatio n

o
d’une EIE comme le préalable indispensable à toute décision concernant la route n 1856. Il s’agit

111
Submissions, par. 2 iv). - 55 -

là non pas de l’objet de la requête du Nicaragua, mais d’un acte préalable, préparatoire, nécessaire

pour évaluer le bien-fondé de celle-ci.

16. Telle est d’ailleurs aussi la manière dont le Costa Rica lui-même voit les choses :

«States are under an obligation to ensure that such activities within their
jurisdiction and control do not cause damage to the environment of other States or
areas beyond their national jurisdiction 112. Stemming from this obligation, a proper

environmental impact assessment is a prerequisite . A State is obliged, as a matter of
general international law, to assess the extent to which activities within its jurisdiction
will cause ha rm to other States, particularly in areas or regions of shared

environmental conditions, and to consult with neighbouring 113te114bout the
environmental implications of the planned activities .»

Je ne saurais mieux dire, Monsieur le président : l’EIE est une condition préalable, a prerequisite, à

l’appréciation du bien-fondé de toute action envisagée dans des circonstances de ce genre.

17. Telle est aussi la très ferme position prise par la Cour, qui a rappelé, dans l’affaire des

Usines de pâte à papier, l’existence d’

«une pratique acceptée si largement par les Etats ces dernières années que l’on peut

désormais considérer qu’il existe, en droit international général, une obligation de
procéder à une évaluation de l’impact sur l’environnement lorsque l’act ivité
industrielle projetée risque d’avoir un impact préjudiciable important dans un cadre
transfrontière, et en particulier sur une ressource partagée. De plus, on ne pourrait

considérer qu’une partie s’est acquittée de son obligation de diligence, et du devoir de
vigilance et de prévention que cette obligation implique, dès lors que, prévoyant de
réaliser un ouvrage suffisamment important pour affecter le régime du fleuve ou la

qualité de ses eaux, elle n’aurait pas procédé à une évaluation de l’impact s 115 ur
l’environnement permettant d’apprécier les effets éventuels de son projet.»

Tout récemment, le Tribunal arbitral constitué dans l’affaire du Barrage de Kishenganga a

également rappelé avec fermeté l’obligation d’évaluer le risque écologique avant de pr océder à la
116
réalisation de tout projet de ce type .

18. Il s’agit bien d’une condition préalable, préparatoire, conservatoire par excellence, en

l’absence de laquelle aucune action ne peut être décidée ou entreprise  et aucune appréciation du

bien-fondé d’une telle action ne peut être faite en connaissance de cause. Comme la Commission

du droit international l’a noté dans son pourtant très prudent projet d’articles sur la prévention des

dommages transfrontières :

«Toute décision relative à l’autorisatio n d’une activité entrant dans le champ
d’application des présents articles, repose, en particulier, sur une évaluation du

dommage transfrontière possible du fait de cette activité, dont une évaluation de
l’impact sur l’environnement.» 117

19. Dans la lettre qu’il a adressée à l’agent du Nicaragua le 11 mars 2013, le greffier

indiquait que la Cour était d’avis «that the circumstances of the case, as they now present

themselves to it, are not such as to require the exercise of its power under Article 75 of the Rules of

118
Court to indicate provisional measures proprio motu» . Outre qu’il n’est plus demandé à votre

haute juridiction de se prononcer proprio motu, sans avoir été éclairée par les éléments de preuves

discutées par les Parties, les circonstances elles- mêmes ont changé et l’exigence préalable d’une

EIE s’est faite particulièrement pressante du fait de l’annonce par le Costa Rica de son intention de

reprendre les travaux de construction de la route n o 1856.

[Fin de la projection n 1  Projection n 2 : La deuxième mesure conservatoire demandée par le
Nicaragua.]

2. La deuxième mesure conservatoire demandée par le Nicaragua

20. Monsieur le président, la deuxième mesure conservatoire  ou plutôt la deuxième série

de mesures conservatoires  que le Nicaragu a prie la Cour de bien vouloir indiquer est plus

complexe. Ces demandes sont projetées à l’écran en ce moment et figurent à l’onglet no 14 du

dossier des juges.

21. L’érosion des rives du fleuve est continue ; et l’éboulement des pentes de la route

menace constamment. Tout ceci est d’autant plus préoccupant que tout accident météorologique se

traduira inévitablement, si l’on n’y veille, par une aggravation dramatique de la situation.

et 7).
118
Lettre en date du 14 mars 2013 adressée à l’agent du Nicaragua par le greffier (réf. 141600). - 57 -

22. Or, depuis que le Nicaragua a déposé sa requête, pratiquement rien n’a été fait et la

situation s’est au contraire considérablement dégradée, ce que confirme le rapport du

professeur Kondolf de la semaine dernière :

«Our field observations in October 2013 clearly showed that erosion is actively
occurring along multiple parts of the road, and that erosion control and drainage works

have been ine119ctive in addressing the serious erosion and slope stability
problems.»

23. Des mesures conservatoires d’urgence semblent, dans ces conditions, plus qu’amplement

justifiées. L es quatre mesures concrètes que le Nicaragua prie la Cour de bien vouloir indiquer

sont de nature à éviter l’accumulation des dommages causés au fleuve  dont il me paraît

120
important de rappeler à nouveau qu’il est sous souveraineté nicaraguayenne  et ces mesures

semblent relativement aisées à mettre en Œuvre.

24. [Surligner 2 a)] La première de ces mesures s’avère tout particulièrement nécessaire car

comme l’écrivait le professeur Kondolf dès décembre 2012,

«[s]ediment eroded from Route 1856 has already reached the Río San Juan through a
number of pathways» 121.

25. Le professeur de Berkeley n’est pas seul à s’alarmer des risques d’affaissement de la

route. Ainsi, dans un rapport de mai 2012 (mais la situation ne s’est pas améliorée depuis lors bien

au contraire), le laboratoire national des matériaux et des modèles structurels de l’Université du

Costa Rica dénonçait the «high risk of collapsing during the rainy season as a result of nonexistent

drainage structures and instability of a large number of cuts and fills»and stressed that,

«Leaving the Border Trail in full operating condition immediately requires a
major additional investment of resources to build missing drainage structures,

complete and stabilize many cut and fill sectors, and particularly b uild bridges over
Sarapiquí, San Carlos, and Pocosol rivers.» 122

(MN, annexe 4, vol. II, p. 284). - 58 -

26. Ces propositions du laboratoire costa -ricien rejoignent largement les mesures

conservatoires que le Nicaragua prie aujourd’hui la Cour d’indiquer conformément aux

préconisations du profess eur Kondolf  que je n’ai pas le temps de lire ; mais elles se trouvent

sous l’onglet n o15 du dossier des juges. En les lisant, vous pourrez constater, Mesdames et

Messieurs de la Cour, à la fois combien elles sont indispensables, précises, raisonnables, et, autant

que je puisse en juger, relativement faciles à mettre en Œuvre (même si elles doivent l’être

sérieusement).

27. [Surligner 2 b) ] En deuxième lieu, Monsieur le président, le Nicaragua a prié la Cour

d’indiquer au Costa Rica qu’il doit d’urgenc e «(b) Eliminate or significantly reduce the risk of

future erosion and sediment delivery at all stream crossings along Route 1856.»

28. Les vices qui entachent la conception et la construction des nombreux franchissements

de cours d’eau (stream crossings) par la route 1856 (il en existe déjà une soixantaine) en font des

endroits particulièrement exposés en cas de pluies. En conséquence, comme le souligne le

professeur Kondolf, ils peuvent être à l’origine de déversements massifs dans le fleuve et de

pollutions très importantes 12.

29. Ici encore ces observations rejoignent celles du laboratoire de physique des matériaux de

l’Université du Costa Rica qui dénonce «the poor management of this issue [concerning the

stream-crossing] in the project» 124.

30. Dès mai 2012, ce laboratoire costa-ricien faisait les propositions suivantes pour tenter de

remédier à la situation :

«Completing the construction of adequate drainage structures in trail sectors
having a stable gravel platform as a high priority, in order to protect road investment
and functionality.

Building drainages in the other road sectors consisting of a dirt trail. All these
drainage works should be designed according to hydrological requirements in the area
and existing waterbody hydraulic characteristics.» 125

31. Rien n’ayant bien sûr été fait en ce sens depuis lors, les propositions du

professeur Kondolf qui vont dans le même sens et que relaient les demandes du Nicaragua

paraissent faire l’unanimité des spécialistes au moins lorsqu’ils se prononcent à titre indépendant.

Les recommandations motivées du professeur Kondolf figurent sous l’onglet n o16 du dossier des

juges. Comme les précédentes, il me semble qu’elles méritent une lecture attentive.

32. [Surligner 2 c) ] Les deux autres mesures d’urgence que, selon nous, la Cour devrait

indiquer dans son ordonnance sont étroitement liées l’une à l’autre.

33. Dès son premier rapport, le professeur Kondolf avait attiré l’attention sur l’importance de

l’érosion de surface :

«We estimate that an annual and ongoing sediment input of 87,000 to 109,000
cubic meters [reaches the San Juan]. Future erosion and sediment delivery during a
tropical storm or hurricane will likely be greater than the current sediment transfer by
126
a factor of at least ten.»

34. Dans son rapport du 30 octobre de cette année, M. Kondolf montre que l’effet de cette

127
érosion massive se fait sentir immédiatement sur le fleuve et il rappelle combien les pluies

abondantes favorisent cette érosion 128. Il y constate en outre que les choses ne se sont pas

améliorées malgré quelques aménagements de fortune :

«Our field observations in October 2013 clearly showed that erosion is actively

occurring along multiple parts of the road, and that erosion control and drainage works
have been ineffecti ve in addressing the serious erosion and slope stability
problems.» 129

35. Et, conformément à la méthode constamment suivie par l’expert, celui -ci conclut cette

partie de son rapport en faisant un certain nombre de propositions précises et très concrètes, qui

o
sont reproduites sous l’onglet n 17 du dossier des juges. On peut considérer la demande 2 c) que

nous formulons comme une version abrégée de (et une référence à) ces préconisations.

36. [Surligner 2 d)] Par ailleurs, dans son rapport de 2012  et ceci se rapporte davantage à

la mesure 2 d)  le professeurKondolf dénonce

«The evident lack of measures to prepare for the wet season and lack of erosion
control measures along the route has resulted in persistent and serious erosion of bare

soils all alo ng the recently bulldozed alignment and at disturbed rock quarry sites .
Much of this eroded sediment has been delivered to the Río San Juan.» 130

37. Ici encore, ces constatations débouchent sur des propositions de sauvegarde que l’expert

131
consulté par le Ni caragua énonce dans son rapport du 12 octobre 2013 . Elles sont reproduites

o
sous l’onglet n 18 de vos dossiers.

38. Les recommandations du Professeur Kondolf rejoignent celles  malheureusement

jamais suivies d’effet  faites dès mai 2012 par le laborat oire de physiques des matériaux de

l’Université du Costa Rica :

«Expanding the use of erosion stabilization and control practices to the different
project sectors requiring them. Assessing the use of vegetative methods that could be
132
easily applied in several sectors.»

Je note en passant qu’aux fins de la présente instance, la Partie costa- ricienne s’est bien gardée de

133
faire appel à l’expertise considérable réunie dans ce laboratoire...

39. Monsieur le président, les photos qu’ont projetées mes collègue s ne me paraissent pas

laisser de grands doutes sur les graves malfaçons qui marquent la construction de la route ; et les

risques en résultant pour le San Juan paraissent également assez évidents même à un Béotien.

Mais, pas davantage, sans doute, que la très grande majorité des juristes, je n’ai la moindre idée sur

la manière dont, techniquement, on peut supprimer ces risques ou, au moins, en diminuer

l’intensité. Et c’est la raison pour laquelle nous avons reproduit les conclusions du

professeur Kondolf dans le dossier des juges, afin de bien montrer que nous n’avons rien inventé.

40. Monsieur le président, je ne pense pas qu’il faille avoir du principe de précaution une

conception rigide et dogmatique car on risque alors l’immobilisme. Il n’en reste pas moins que les

prévisions à la fois très posées et alarmistes du Professeur Kondolf ne doivent pas être prises à la

légère : il existe, indiscutablement, un risque grave et imminent de préjudice irréparable, et des

mesures doivent et peuvent être prises pour le minimiser. L’indication des mesures

suggérées par le Nicaragua dans le point 2) des demandes formulées dans la lettre de

l’ambassadeur ArgüelloGómez du 11 octobre dernier irait dans le sens de cette minimisation.

o o
[Fin de la projection n 2. Pr ojection n 3 : La troisième mesure conservatoire demandée par le

Nicaragua/The Third Provisional Measures Requested by Nicaragua.]

3. La troisième mesure conservatoire demandée par le Nicaragua

41. Monsieur le président, dans le point 3 de ces mêmes con clusions, le Nicaragua prie la

Cour to «Order Costa Rica not to renew any construction activities of the road while the Court is

seized of the present case.»

42. Cette demande paraît, à vrai dire relever du simple bon sens. Dans votre ordonnance du

8 mars 2011, vous avez, Mesdames et Messieurs de la Cour, enjoint à l’unanimité aux Parties de

«s’abst[enir] de tout acte qui risquerait d’aggraver ou d’étendre le différend dont [elle] est saisie ou

d’en rendre la solution plus difficile» 134 et, toujours à l’unan imité, vous avez réaffirmé «en

135
particulier» cette mesure dans votre ordonnance du 16 juillet 2013 . Certes, cette injonction est

contenue dans les ordonnances relatives à l’affaire Costa Rica c. Nicaragua alors que la reprise de

o
la construction de la rout e n 1856 relève plus directement de Nicaragua c. Costa Rica ; mais,

comme le confirme leur jonction, les deux affaires sont étroitement liées et il n’est pas douteux que

la relance des travaux envisagée par la Partie costaricienne aggravera considérablement la

134Certaines activités menées par le Nicaragua dans la région frontalier (CosRica c. Nicaragua), mesures
conservatoires, ordonnance du 8 mars 2011, C.I.J. Recueil 2011 (I), p. 27, par. 86, point 3).

sédimentation du fleuve San Juan, rendant ainsi impossible le rétablissement de la situation

136
existante en 1858 à laquelle le Nicaragua a droit .

43. Du reste, la mesure que vous avez ordonnée en 2011 et réaffirmée en juillet dernier, n’est

que l’expression d’une obligation plus générale. On peut en effet considérer que les parties à toute

affaire portée devant la Cour sont tenues de ne pas aggraver la situation et de ne pas rendre plus

difficile le règlement du différend. Cette obligation est, en quelque sorte, le substrat, l’arrière-plan,

de toutes les autres mesures conservatoires que vous indiquez.

44. Comme vous l’avez rappelé dans vos ordonnances du 23 janvier 2007 et du

8 mars 2011 :

«la Cour a déjà indiqué à plusieurs reprises des mesures conservatoires ordonnant à
l’une ou l’autre des parties, voire aux deux, de s’abstenir de tous actes de nature à
137
aggraver ou étendre le différend ou à en rendre la solution plus difficile» .

et, vous avez ajouté que :

«dans ces affaires, des mesures conservatoires autres que celles ordonnant aux parties
de s’abstenir de tous actes de nature à aggraver ou étendre le différend ou à en rendre
la solution plus difficile ont été également indiquées…» 138

45. Dans notre espèce, l’adoption d’une mesure rappelant au C osta Rica qu’il ne doit pas

o
entreprendre de nouveaux travaux de construction de la route n 1856 aussi longtemps que votre

arrêt sur le fond n’aura pas été rendu n’est que la conséquence évidente de l’obligation dans

laquelle il se trouve  comme le Nicaragua d’ailleurs  de ne pas aggraver le différend. C’est

aussi, typiquement, une mesure entrant dans le cadre du

«droit pour la Cour d’indiquer des mesures conservatoires, prévu à l’article 41 du
Statut, [qui] a pour objet de sauvegarder les droits des parties en attendant que la Cour

rende sa décision, [et qui] présuppose qu’un préjudice irréparable ne doit pas être

causé aux droits en litige devant le juge et qu’aucune initiative concernant les mesures
139
litigieuses ne doit anticiper sur l’arrêt de la Cour» .

46. En effet, ici, comme, mutatis mutandis, dans l’affaire de la Compétence en matière de

pêcheries, la reprise de travaux de construction de la route par le Costa Rica, en anticipant sur

l’arrêt de la Cour, «porterait préjudice aux droits invoqués pa r le [Nicaragua] et nuirait à la

140
possibilité de leur rétablissement intégral au cas où la Cour se prononcerait en sa faveur» .

47. J’ajoute que votre haute juridiction a eu, à maintes reprises, l’occasion d’ordonner la

suspension ou la non-reprise de certaines activités dans ses ordonnances en indication de mesures

conservatoires 141. Certes, dans deux affaires qui présentaient certains points communs avec celle

qui nous occupe  celle du Grand Belt et celle des Usines de pâte à papier , la Cour a refusé

d’indiquer les mesures conservatoires demandées par l’Etat requérant. Mais, comme l’a

excellemment montré Paul Reichler, la question qui nous retient s’y posait, en réalité, tout à fait

différemment, en particulier parce que le caractère imminent de la menace, qui faisait défaut dans

ces deux affaires, n’est pas douteux dans la nôtre et, faute d’une ordonnance de la Cour, elle se

concrétisera bien pendente litis.

48. A cet égard, je relève que, assurément, il est difficile de préciser la date exacte à laquell e

celle-ci se concrétisera car la reprise annoncée des travaux semble se heurter à des difficultés

142
financières et à des soupçons de corruption . Mais la ferme volonté des autorités costa- riciennes

d’y procéder dès que possible ne fait pas le moindre doute : la date de passation des contrats

nécessaires au début des travaux et celle de leur commencement effectif ont été plusieurs fois

143
annoncées et repoussées, mais ceci n’a visiblement pas entamé la résolution des plus hautes

autorités de l’Etat de procéder aux travaux aussitôt que possible, sans égard pour l’affaire

actuellement pendante devant la Cour. Pas plus tard que la semaine dernière, et je crois important

de le citer à nouveau, le ministre costa-ricien de la Communication déclarait encore :

«that construction of the Borderline Trail will continue to a priority piece of work until
termination by the current government and anticipates that it will also be (a priority)

for the next (government).

In addition, he emphasized that the works will continue forward even though
144
this does not please Nicaragua.»

49. Au demeurant, l’absence de date précise n’empêche nullement qu’une menace de risque

irréparable soit considérée comme imminente et, par conséquent, comme étant de nature à justifier

145
l’indication de mesures conservatoires propres à écarter une telle menace . Monsieur le président

je ne me hasarderai pas à avancer la date à laquelle les travaux de construction de la route

débuteront à nouveau ; mais la décision est prise et, même s’il est impossible de déterminer

précisément la date à laquelle elle se concrétisera, la menace est suffisamment réelle pour que cette

incertitude ne soit pas «de nature à interdire à la Cour d’indiquer des mesures conservatoires» et,

tout spécialement, la non- reprise des t ravaux en question. De toute évidence, à moins que le

Costa Rica se borne à jouer des nerfs des dirigeants nicaraguayens par des provocations pures et

simples, ces nouveaux et désastreux travaux interviendront «avant que la Cour n’ait eu l’occasion

146
de rendre sa décision définitive» . Il est donc plus que probable que, si la Cour n’intervient pas,

«une action préjudiciable aux droits de l’une ou de l’autre Partie sera commise avant que la Cour

147 148
n’ait rendu sa décision définitive » .

50. Et il y a une autre raison  tout aussi décisive que celles que je viens d’exposer.

51. Par une décision préliminaire du 17 janvier 2012, la Cour de justice centraméricaine a

ordonné :

«To immediately suspend the construction of the road that the Government of
Costa Rica i s building parallel to the south bank of San Juan River, so that the

situation does not escalate, thus protecting the rights of each of the parties 149
preventing the occurrence of irreversible and irreparable damage.»

Or, comme l’a relevé la même Cour dans sa décision du 21 juin 2012, dont certains extraits

figurent au dernier onglet de votre dossier,

«These protective measures were not respected by the State of Costa Rica,
violating Article 39 of the Convention on the Statute of the Central American Court of
150
Justice…» ,

ce qui a conduit la Cour de Managua à condamner le Costa Rica «for incurring in contempt of court

by not complying with the precautionary measures ordered by the Central American Court of

Justice on January seventeen, two thousand twelve» and the Court added: «the order to definitively

151
suspend the construction of this road is reaffirmed» . Le Costa Rica s’est empressé de proclamer

qu’il ne respecterait pas cette décision 152.

52. Certes, Monsieur le président, la Cour de céans n’est pas un «agent d’exécution» de la

Cour de justice centraméricaine ; mais les décisions de celles- ci sont obligatoires pour les Parties

en vertu de l’article 39 du traité l’instituant ; peu importe qu’il s’agisse d’obligations «secondaires»

plutôt que «primaires»  elles s’imposent aux Parties. En indiquant la troisième mesure

demandée par le Nicaragua, vous ne ferez, Mesdames et Messieurs les juges, que confirmer, avec

l’autorité particulière qui est la vôtre, la décision prise à deux reprises  et à l’unanimité mais en

vain  par la Cour de Managua et vous ferez ainsi respecter le principe sacré de la res judicata.

53. Monsieur le président, le Costa Rica aime à donner des leçons de bonne conduite et de

moralité internationales. La présente affaire montre à quel point il peut faire fi de ses principes s’il

estime n’y pas trouver son compte :

o
1) la poursuite de la construction de la route n 1856 confirmerait l ’outrage au tribunal  the

contempt of Court  dont il est responsable en faisant fi des décisions dépou rvues de toute

ambiguïté de la Cour d’Amérique centrale lui enjoignant de cesser ces travaux ;

2) la reprise des travaux, annoncée comme imminente, porterait une atteinte irréversible à

l’environnement du San Juan et aux droits que le Nicaragua a entendu faire respecter en portant

le présent différend devant la Cour ;

3) en tout état de cause, il est impossible à quiconque  même à votre haute juridiction,

Mesdames et Messieurs les juges, de prendre quelque décision éclairée que ce soit concernant

tant le t ronçon déjà construit de la route que ceux que le Costa Rica continue à vouloir

construire, en l’absence d’une étude d’impact environnemental sérieuse, préalable et nécessaire

à toute action future et à toute appréciation du fait accompli jusqu’à présent ; et

4) il n ’est guère envisageable de laisser le statu quo produire ses effets catastrophiques en

attendant votre arrêt ; des mesures d’urgence s’imposent dans la ligne des recommandations très

motivées du professeur Kondolf (qui elles -mêmes vont dans le même sens que les

préconisations du laboratoire costa-ricien de physique des matériaux et de la modélisation, que

le Costa Rica tient dorénavant soigneusement à l’écart).

54. Monsieur le président, Mesdames et Messieurs les juges, ceci conclut les plaidoi ries du

premier tour du Nicaragua. Nous vous remercions bien sincèrement de votre écoute  d’autant

plus «méritoire» si je peux dire, que vous aviez déjà dû siéger, il y a peu, pour entendre les

plaidoiries des mêmes Parties sur un autre volet de ces affa ires jointes. Je me permets

respectueusement de dire que je continue de penser  nous continuons de penser  que s’y arrêter

ne vous aurait permis de n’avoir qu’une vue très partielle et fort déséquilibrée des choses. Merci de

nous avoir donné l’occasion de les remettre en perspective. Je vous souhaite un excellent appétit.

Le PRESIDENT : Merci Monsieur le professeur. Ceci met fin à l’audience d’aujourd’hui.

La Cour se réunira demain à 10 heures pour entendre le Costa Rica dans son premier tour des

arguments oraux. Je vous remercie. La séance est levée.

La séance est levée à 13 h 5.
