The U.S. Court of Appeals for the Third Circuit on Wednesday extinguished a prisoner lawsuit targeting over-detention in Delaware correctional facilities, citing a lack of evidence that state officials were deliberately indifferent to the “consistent problem” of delayed inmate releases.

In a precedential opinion, a three-judge panel of the appeals court sided with a lower court’s ruling that denied class certification in the case and granted summary judgment in favor of high-ranking corrections officials, who had moved in recent years to address the issue.
