The study introduces a multidimensional solution to impose universal jurisdiction by utilizing firm concepts in international law to enhance the functionality of this principle in international legal practice. Initially, it explores the current classification of the principle of universal jurisdiction in international law to determine its latest status quo. It is prominent to introduce a comprehensive presentation of the structure of universal jurisdiction and its relevant concepts in international law by reviewing international jurisprudence on this principle. Thus, the study reviews its evolution in international legal instruments and how international courts utilise them. In addition, the research analyzes the UN relevant resolutions on universal jurisdiction to draw a global portrait of its legal status in international law. Because of the cosmopolitan humanitarian ends of universal jurisdiction, the research suggests employing the concept of humanness to justify imposing it. In addition, these ends, and the purpose of enhancing international justice, drive the study to introduce the theory of the responsibility to protect (R2P) to justify the utilization of domestic legal rules extra-territorially. Nevertheless, this utilisation might trigger the question of national judiciaries’ independence. The research analyzes this problem to establish the required foundations to strike a balance between the independence of national judiciaries and imposing universal jurisdiction to secure justice.
