Before an investigation can begin, the Office of the Prosecutor (OTP) conducts a preliminary examination to decide whether there is enough information on crimes of sufficient gravity, providing a reasonable basis to open an investigation. During this examination, OTP analyses whether or not the ICC has jurisdiction (a crime listed in the Rome Statute appears to have been committed by a national of a State Party or on the territory of a State Party, after 1 July 2002); whether an investigation would be admissible (a national court is not already dealing with it); and whether or not an investigation would be in the interests of justice and of the victims (here OTP considers whether, regardless of jurisdiction and admissibility, there is some good reason not to take on this situation).
