The Groups Registry
Welcome to the Groups Registry. It was launched in October 2020, and existing cases are still being added. You can tell us about cases that should be included on this Registry by emailing us at info@exonerationlist.org
This is our third registry. It joins our main archive and our pre-1989 archive of individual exonerations. This new registry focuses on groups of defendants tied together by a common pattern of systematic official misconduct in the investigation and prosecution of these cases that undermined confidence in the defendants' convictions.
