The book discusses the Principle of Universal Jurisdiction and proposes the way forward in combating international criminals. It also discusses the challenges that the principle faces in its implementation especially in the context of Africa. Though the Principle has its merits in terms of eradication of impunity, it also has practicle challenges. It is however equally important to note the role of emerging ad hoc International Courts/Tribunals as well as The International Criminal Court. They have significantly contributed to the effort in the fight against grave violation of Human Rights in general and International Criminal Law in particular. These combined efforts together with the national courts will, inevitably, in the near future bring to an end the violation of Human rights and will make the world a better space for living.
