This book focuses on queer people and their encounters with international law. Traversing a wide range of topics, from trans discrimination and conversion therapy to sadomasochism and abolitionism, this book asks questions about the (im)possibility of freedom and equality for queer communities in the world and the role that different areas of international law have to play in such a pursuit. It considers how queer lives and bodies are rendered legible or illegible to the law through how we define concepts such as ‘gender [identity]’ or ‘private life’. It also reflects on whether legal activism focused on LGBTIQA+ rights can ever reflect the insights of queer theory. The book engages with new issues in international law, such as recent contestation over the meaning of ‘gender’ in international human rights law and international criminal law. It also showcases the diversity of approaches to queering international law that are emerging. While some chapters offer a critique of international law’s violent and exclusionary tendencies, others re-invest in international law as a tool in the struggle for queer liberation by seeking to re-imagine it in queer directions. The questions addressed in this book are wide-ranging and approached differently by the authors. However, all centre on the complex relationship between international law, queer theory, and queer lives and what the future holds for these encounters going forward. This collection of queer encounters with international law will be invaluable to scholars of international law, human rights, and international relations with an interest in critical approaches to these areas, as well as to researchers, activists, and practitioners working in cultural, gender, and sexuality studies.
