The Rome Statute obliges states parties to cooperate with the Court in the investigation and prosecution of crimes, including the arrest and surrender of suspects.[15] Part 9 of the Statute requires all states parties to ensure that there are procedures available under their national law for all of the forms of cooperation which are specified under this Part.[16]
Under the Rome Statute's complementarity principle, the Court only has jurisdiction over cases where the relevant state is unwilling or unable to investigate and, if appropriate, prosecute the case itself. Therefore, many states parties have implemented national legislation to provide for the investigation and prosecution of crimes that fall under the jurisdiction of the Court.[17]
As of October 2024, 68 states have adopted at least one piece of complementarity legislation, 59 have adopted at least one cooperation law, 52 have adopted neither, and 55 have adopted both, whereas 13 have implemented complementarity only and 4 have implemented cooperation only.[18]
