Abstract

Climate change is a global phenomenon that has various impacts on human life, including the maritime territories of states. Rising sea levels, coastal erosion, and the submergence of small islands have the potential to alter geographical conditions that have long served as the basis for the determination of maritime boundaries. These changes give rise to legal issues related to territorial certainty, the exercise of state sovereignty, and the management of marine resources. This study aims to analyze the regulation of maritime boundaries under international law and to examine the challenges posed by climate change to the determination of state maritime boundaries. The research addresses two main questions: how maritime boundaries are regulated under international law and what challenges arise in determining maritime boundaries due to climate change. The study employs normative legal research using statutory and conceptual approaches through an examination of various international legal instruments, particularly the United Nations Convention on the Law of the Sea (UNCLOS) 1982. The findings indicate that climate change has the potential to affect baselines, which serve as the basis for measuring a state's maritime zones. Furthermore, issues of vague norms, conflicts of norms, and legal vacuums exist within international law concerning the status of maritime boundaries affected by geographical changes resulting from sea-level rise. This study concludes that the development of a more adaptive international legal framework is necessary to ensure legal certainty, protect state sovereignty, and prevent future maritime disputes.

Abstract

Globalization has encouraged increasing interactions among individuals and legal entities originating from different countries. Developments in technology, international trade, foreign investment, and cross-border population mobility have given rise to various legal relationships containing foreign elements. These conditions create legal issues that cannot be resolved solely based on a single national legal system. In such circumstances, Private International Law plays a role as a branch of law that regulates private legal relationships connected to more than one country. This article aims to examine the definition, scope, fundamental principles, and role of Private International Law in resolving cross-border legal issues. This study employs a normative legal research method using statutory and conceptual approaches through library research. The findings indicate that Private International Law has an important function in determining judicial jurisdiction, the applicable law, as well as the recognition and enforcement of foreign judgments. The existence of Private International Law provides legal certainty and protection for parties involved in legal relationships containing foreign elements. As cross-border relations continue to increase, the role of Private International Law becomes increasingly important in realizing justice and legal certainty in the era of globalization.
