25.      Against that background, The Kingdom of Spain wishes to explain that it is for the State
Party bringing a case against another State Party for a false allegation of genocide used
as a basis to justify preventive action to provide prima Jacie evidence that its action did
not fall under the definition ofgenocide as laid down in Article 11. In turn, the respondent State
asserting that its allegation was weIl-founded to justify its preventive action must provide
conelusive evidence in support since this attempted justification involves charges of
exceptional gravity. 15 After adversarial scrutiny, it would then be for the Court to
evaluate all the evidence produced by the two Parties so as to reach its own conelusions. 16
