Abstract: What is known as crime against humanity in the statute of the international criminal court is considered as a crime in Iran’s penal code. They have differences in title and contents despite similarities and equality of the action by itself and actions being committed and the collection of actions which are entitled as genocide in statute of the court has other different and special titles such as murderer, etc. in Islamic Penal Code (IPC) and they are special crimes and have their own penalties. Even assuming that there are conflicts between provisions of the articles of associations and laws of Iran, there is no legal and religious objections regarding the agreement of Islamic governments and non-Islamic countries. What the urgencies of the Islamic society demands is signing agreements and treaties with non-Muslim societies which is necessary and urgent. In the statute of the international criminal court, there is no penalty like execution or whipping. Because of the principle of being complementary of the court and the system of acceptability and principals of validity of the done deal and deterrence of punishment and doubled penalty and especially considering the Article 80th of the statute in which protects and supports the competence of national legislation, the possibility of performing a sentence or punishment conflicting with provisions of Islam and Islamic Republic of Iran is too far from reality and unlikely.
