A polycentric system of international criminal justice: reconfiguring accountability in a transforming global order

The global order is undergoing significant transformations with far-reaching implications for international criminal justice. These shifts pose an existential challenge to core crimes accountability while re-shaping its pursuit. As the liberal order recedes, the International Criminal Court (ICC) faces a crisis driven by absolute sovereignty’s reassertion, weakened multilateral governance and increasing political and coercive pressures from powerful states. Simultaneously, these developments promote decentralised accountability, fostering the emergence of a polycentric system of international criminal justice. Trends in re-nationalisation, hybridisation and regionalisation align accountability with a more pluralistic, fluid global order. In this context, the ICC is not obsolete but requires a redefined role. While no longer the apex of international criminal justice, its existence remains crucial to addressing the risks of decentralised accountability. The Court, particularly its Office of the Prosecutor, should reconfigure strategies around positive complementarity, repositioning itself as a co-ordinating hub within this polycentric system.
