ABSTRACT
Jurisdiction forms the backbone of international law because it determines the authority of States to regulate conduct, enforce laws, and administer justice within and beyond their territorial boundaries. Traditionally, jurisdiction was closely linked to the principle of territorial sovereignty, under which States exercised exclusive control over activities occurring within their borders. However, the rapid growth of globalisation, transnational commerce, cyber operations, international terrorism, and human rights concerns has significantly transformed the traditional understanding of jurisdiction. This paper critically examines the evolution of jurisdiction in contemporary international law by analysing the traditional principles of territoriality, nationality, passive personality, protective principle, and universal jurisdiction. It further explores the increasing expansion of extraterritorial jurisdiction and the legal conflicts arising from overlapping claims by multiple States. The study also evaluates procedural limitations such as sovereign immunity, diplomatic immunity, and the immunity of State officials, while analysing the role of international tribunals such as the International Court of Justice and the International Criminal Court in ensuring global accountability. Special attention has been given to modern jurisdictional challenges emerging from cyberspace, outer space activities, and transboundary environmental harm, where traditional territorial approaches appear increasingly inadequate. Through a doctrinal and analytical methodology based on international conventions, judicial precedents, and State practice, the paper argues that international law is gradually shifting from rigid territorial models towards more flexible and functional forms of jurisdiction. The paper concludes that effective international cooperation and clearer jurisdictional standards are essential for maintaining legal certainty, sovereign balance, and global justice in an increasingly interconnected world.
