The U.S. Supreme Court on Friday upheld a federal ban on firearms for people under domestic violence restraining orders.

The 8-1 opinion was authored by Chief Justice John Roberts. Justice Clarence Thomas dissented.

“When a restraining order contains a finding that an individual poses a credible threat to the physical safety of an intimate partner, that individual may—consistent with the Second Amendment—be banned from possessing firearms while the order is in effect,” Roberts wrote. “Since the founding, our Nation’s firearm laws have included provisions preventing individuals who threaten physical harm to others from misusing firearms.”
