paragraph_text: Establishing the court's jurisdiction
  
  The process to establish the court's jurisdiction may be "triggered" by any one of three possible sources: (1) a state party, (2) the Security Council or (3) a prosecutor. It is then up to the prosecutor acting proprio motu to initiate an investigation under the requirements of Article 15 of the Rome Statute. The procedure is slightly different when referred by a state party or the Security Council, in which cases the prosecutor does not need authorization of the Pre-Trial Chamber to initiate the investigation. Where there is a reasonable basis to proceed, it is mandatory for the prosecutor to initiate an investigation. The factors listed in Article 53 considered for reasonable basis include whether the case would be admissible, and whether there are substantial reasons to believe that an investigation would not serve the interests of justice (the latter stipulates balancing against the gravity of the crime and the interests of the victims).
