Gender-Based Crimes in International Law

Gender-based crimes, particularly those involving sexual and reproductive violence, have been progressively articulated through statute norms, judicial decisions, and institutional policies, reflecting an expanding consensus on their legal recognition in international law. While sexual and reproductive violence have long occurred in armed conflict and other contexts of systemic oppression, the legal recognition and prosecution of these acts have developed unevenly across international statutes and tribunals. This entry provides a structured analysis of how gender-based crimes, specifically those involving sexual violence and reproductive harm, are conceptualized and prosecuted under international law. This entry begins by conceptualizing ‘gender-based crimes’. The discussion then proceeds in two major parts. The first examines sexual violence crimes, including the legal definition of rape from early jurisprudence such as Prosecutor v Akayesu (1998), through to the codification in the International Criminal Court’s ‘Elements of Crimes’. It outlines the various ways these crimes have been prosecuted: as → crimes against humanity, → war crimes, and → genocide. The second part addresses reproductive violence crimes, tracing their recognition and adjudication under → international criminal law. It also discusses the various ways such crimes can be prosecuted: as crimes against humanity, war crimes, and genocide. The entry also examines the procedural framework and modes of liability applicable to gender-based crimes (→ Criminal Responsibility, Modes of). It concludes with a critical assessment, situates the issue within broader scholarly debates, and affirms the centrality of gender-based crimes to the evolution of international law, while identifying key trajectories for future legal development.
