Universal jurisdiction is a legal principle that allows states to prosecute individuals for serious crimes regardless of where the crime was committed or the nationality of the perpetrator or victim. It is based on the idea that certain crimes are so serious that they affect the international community as a whole. States can exercise universal jurisdiction over crimes like genocide, war crimes, and torture. While the International Criminal Court also prosecutes these crimes, it is limited to crimes committed after 2002 by or on the territories of member states. Universal jurisdiction applies the criminal laws of individual states to bring perpetrators to justice.
