Mr. Longstreth’s practice concentrates in administrative procedure, antitrust and litigation, primarily involving regulated industries. His litigation experience includes numerous federal court and agency proceedings at both the trial and appellate levels, many of which have resulted in reported decisions. He has argued in numerous appellate courts, including multiple times in the D.C., Fourth, and Ninth Circuits, and has been counsel in a number of U.S. Supreme Court and court of appeals proceedings for petitioners, respondents, intervenors, and amicus participants.
Recent successful representations include argument on behalf of a group of electricity sellers defending against refund claims in excess of $100 million, resulting in a decision affirming an interlocutory agency order, and materially supporting the dismissal of the claims in full. The case settled thereafter for a nominal amount. He represented a habeas petitioner on appeal whose certiorari petition was granted in May 2016. He has also handled a number of appeals of agency decisions in the district courts, most recently overturning a Coast Guard rule, which led to substantially increased payments to his clients and recovery of attorney’s fees under the Equal Access to Justice Act.
