After colonisation, African political leaders tended to put themselves in the shoes of the coloniser, an approach that created many dictators on the continent. To combat impunity, the international community set up the ICC to prosecute individuals who commit international crimes such as war crimes, genocide and crimes against humanity, because most of them hid behind institutions. Many African states have individually signed up to the Rome Statute, creating the ICC. The ICC operates on the principle that when a crime is committed and prosecuted under its jurisdiction, the alleged offender does not benefit from diplomatic immunities despite his functions. With regard to the cases of the Sudanese and Kenyan presidents, the AU, which also cooperates with the ICC in the fight against impunity, this time saw that the prosecution of these personalities undermined diplomatic duty and practice.
