25.The African Court already applies this methodology, which is well known in international litigation law. ln addition to generally having the "competence of jurisdiction" in the event of a dispute, the international courts and the international instruments creating them often give them the legal basis to deploy their jurisdiction. ln a complex argumentation the ICJ recalled that it has : "an inherent power which aulhorizes it to take all necessary measures, on the one hand, to ensure that, if its jurisdiction on the merits is established, the exercise of that jurisdiction does not prove futile, and, on the other hand, to ensure the regular settlement of all points in dispute... "1a . Professors Mathias Forteau and Alain Pellet saw this as a kind of implicit jurisdiction within the competence of the lnternational Courl of Justicels. 26.Sometimes the international judge, in order to clarify a position or to explore other aspects inherent in its jurisdiction, uses the applicable law rather than the strict rules which conventionally define and frame its jurisdiction. 27.The affirmation of the role of the ICJ in international human rights law provides an example of this. ln 2010, the Court in The Hague rendered its judgmenton the merits in the case of Ahmadou Sadio Diallo - Guinea v. Congo-Kinshasa'6. The Court ruled on claims of violations of human rights treaties. This case showed that, in addition to having general jurisdiction over the rights of States, r' ,\irtlc,rr 7'tsts (ir.ra (,\'crt laulunl v l:rdnct).
