The Trump administration’s Justice Department is urging the U.S. Supreme Court to reject a Vietnam veteran’s attempt to collect $35,000 in legal fees for his landmark court victory opening potentially billions of dollars in Agent Orange benefits to thousands of so-called “blue water” Navy service members.

Alfred Procopio, represented by retired Navy Cmdr. John Wells of Slidell, Louisiana, is asking the justices to review a decision by the U.S. Court of Appeals for the Federal Circuit that said he is not entitled to fees and costs under the federal Equal Access to Justice Act. The en banc court in September sided with the Justice Department in a one-line summary decision rejecting Procopio’s fee request.
