Since October, the Third Circuit has issued three precedential opinions allowing prosecutors to use evidence collected in violation of the Fourth Amendment.

The most recent one was issued Feb. 6 in a case that involved a warrant that didn't include a list of items to be seized because of a sealing order.

The U.S. Court of Appeals for the Third Circuit is following the lead of the U.S. Supreme Court, which has “pivoted dramatically away from suppression,” said Matthew Stiegler, a lawyer with a federal appellate practice in Philadelphia.
