Global Rights Compliance (GRC) is an international legal foundation focussed on bringing perpetrators to justice for atrocity crimes. The organisation has a presence in the Hague, London, Washington, and Kyiv. GRC is an implementing partner of the Atrocity Crimes Advisory Group (ACA). The ACA is a multilateral initiative established by the United States, the European Union, and the United Kingdom to provide strategic advice and operational assistance to Ukraine’s Office of the Prosecutor General (OPG) in the investigation and prosecution of atrocity crimes in Ukraine. As such, GRC in Ukraine works in support of the Office of the Prosecutor General (OPG) by deploying several Mobile Justice Teams (MJTs) which assist the OPG in all aspects of the investigation, case building and prosecution. GRC’s MJTs operate throughout Ukraine in areas of interest to the OPG.
