V. CHALLENGING ADMISSIBILITY
Article 9
(2) The admissibility of a matter or the jurisdiction of the Court shall be challenged in cases in which the matter is being investigated or prosecuted by the competent bodies of the Republic of Slovenia, or when the charge of the Court refers to a person who has been acquitted or convicted with a final judgement in the Republic of Slovenia, or the criminal proceeding against him has been stayed by final decision or the charge against him has been dismissed with a final decision, and it is not a case in which trial by the Court would be allowed under the third paragraph of Article 20 of the Statute.
Admissibility challenge - State investigation or prosecution
Admissibility challenge - ne bis in idem
