The quick growth of digital technologies and the increasing dependence of nations on cyberspace have led to a notable increase in cybercrime, creating intricate legal challenges on an international scale. Cybercrime crosses national borders, threatens national security, disrupts economic systems, and endangers individual rights, thus requiring a unified international legal response. In this scenario, the function of the International Court of Justice (ICJ) becomes more significant in developing the legal principles that govern State accountability and global collaboration in cyberspace. While the ICJ does not have direct authority over cybercrime, its decisions are vital in clarifying international legal norms related to cyber activities.

This paper examines the contribution of the ICJ to the regulation of cybercrime through its interpretation of general principles of international law, including State sovereignty, due diligence, non-intervention, and attribution of State responsibility. The study analyses how these principles may be applied to cyber operations that facilitate or enable cybercrime, such as cross-border hacking, cyber espionage, and large-scale cyberattacks. The paper further explores the interaction between ICJ jurisprudence and existing international regulatory frameworks, including multilateral conventions, United Nations resolutions, and customary international law, which collectively seek to combat cybercrime.
