The Principle of Universal Jurisdiction in Light of The Harmonization between National Legislation and International Treaties

The universal jurisdiction. Principle perceived as it is a principle in the international criminal law, included criminal specialized owned by each state to trial the perpetrators of the international crimes. By that law each state pretended that it has jurisdiction of criminal juridical upon persons whom suspected that they perpetrators of specified crimes that known as international crimes, outside the borders of the pretended state, regardless of the basics of criminal jurisdiction which existed in the interior legislation for the states such as the nationality of the accused or his state residency For this principle number of justifications, it is integral for international criminal juridical systems for penalty the perpetrators of international crimes on the national level and it is one of the most important approaches to fight fleeing from punishment of international crimes with high risk that influence upon the whole international society The mention principle faced difficulties such as no existed of mechanisms for implemented it or national legislations that stipulated upon it, and the need of international equivalent and agreement about its existence because it is available in some legislation and nor in others.
