Founded in 2001, the GCYILJ provides an authoritative and unique annual survey of developments in global law, governance and jurisprudence. The 2025 Volume marks the Yearbook’s twenty-fifth anniversary and reflects on the endurance of constitutional principles amid global disorder and the pressures reshaping international law, justice, politics, and ethics. Contributions address current systemic crises: geopolitical conflicts, the humanitarian emergency in Gaza, liberal democracies, famine and impunity, multipolarity in international law, international governance, planetary ethics, public-interest litigation before the ICJ, and the ICC’s contested role between Ukraine and Palestine. Alongside these thematic interventions, the volume continues the Yearbook’s hallmark surveys of around twenty international, regional, and quasi-judicial bodies. Its distinctive global outlook and interdisciplinary depth ensure that the Yearbook remains an essential guide to international and global law in a fractured global order.
