A more recent question in international humanitarian law is the discussion about international humanitarian law and its applicability on intra-party violations. Cases such as Prosecutor v Ntaganda have called to question the jurisdiction of the ICC in cases where child soldiers have been victims of sexual violence and sexual slavery. This thesis provides argumentation for expanding the definition of war crimes to also include those crimes that occur in intraparty situations. The risks with the expanded definition are mostly based on the willingness, or unwillingness of the state parties to allow a wider area of jurisdiction in international humanitarian law while the arguments for the expanded definition focus on the victim’s status as either a combatant or hors de combat.
