Six years after Alan Gura convinced the U.S. Supreme Court to strike down the District of Columbia’s ban on guns in the home, he again prevailed in having another city gun regulation declared unconstitutional.

U.S. District Judge Frederick Scullin Jr., a New York judge sitting by designation in Washington, ruled on July 24 that the city’s ban on publicly carrying guns for self-defense was unconstitutional. He cited the high court’s rulings in the earlier D.C. gun case from 2008, District of Columbia v. Heller; and another case, from 2010, in which the court extended gun rights to the states, McDonald v. Chicago.
