Based on the notion that certain crimes are so grave that they affect the international community as a whole, the principle of universal jurisdiction, which entitles a State to prosecute offenders even in the absence of any link between the crime committed and the prosecuting state, is one means of facilitating and securing the repression of such crimes. The rationale of universal jurisdiction is to avoid impunity and to prevent those who committed serious crimes from finding a safe haven in third countries. Indeed, universal jurisdiction enables all States to fulfill their duty to prosecute and punish the perpetrators of war crimes. In order to make this principle effective, States are required to establish universal jurisdiction for war crimes in their national legislation.
