Article 21 of the statute of the ICC as evidence of use of unwritten law by jurisprudence

Abstract: The present work aims to investigate the use, in a comparable way together with the rules of international law, of the unwritten rules, through the jurisprudence of the international criminal justice. A discourse that arises from art. 21 of the statute of the International Criminal Court (ICC), where during the work that the judge has carried out in the international criminal tribunals, has shown that it has been based on an interpretation not only literary of the conventional law, of the statute but also to a broader interpretation formed at an international level and putting in the forefront the final objective, which is the fight against impunity and the protection of victims, who turn to international criminal justice to find their reasons.
