Discrimination is known as an internationally wrongful act. The prohibition of discrimination as a jus cogen in international law is a necessity to protect human rights and fundamental freedoms and guarantee people's dignity, and even in some cases, to maintain international peace and security.

These international reactions did not stop even after the end of the apartheid era, so in 1998, apartheid was included as an instance of crimes against humanity in the Statute of the International Criminal Court (ICC).

In fact, it is the increasing (but contested) use of the term apartheid in Israeli laws and actions in the Occupied Palestinian Territories (OPT) that led to individual criminal prosecution in this context. In other words, although the inclusion of the Apartheid Convention on Israel's action
