A federal judge told D.C. to stop enforcing its concealed-carry gun law, which requires people to have a “good reason” in order to get a permit from police to carry guns.

This may seem like deja vu … and that’s because it isn’t the first time a federal judge overturned District legislation on guns. The previous ruling prompted the D.C. Council to pass a law designating where licensed owners can carry handguns in public. They have to demonstrate they have a “good reason to fear injury to his or her person or property” or “any other proper reason for carrying a pistol.”

And it’s this legislation that U.S. District Judge Richard J. Leon ruled today is likely unconstitutional because it is “inconsistent with the individual right to bear arms under the Second Amendment,” and that the plaintiffs “will suffer irreparable harm absent preliminary injunctive relief, and that the equities and the public interest weigh in plaintiffs’ favor.” He granted the plaintiffs’ request for a preliminary injunction, meaning the D.C. Police can’t enforce the law.

The plaintiffs in the case are the shooting group Pink Pistols and Matthew Grace.

“We thank the Court for its probity in this matter, and shall continue to move forward to safeguard the natural rights of our members and the public to exercise their rights,” Pink Pistols spokesperson Gwendolyn Patton said in a release.

The D.C. Police referred comment to the Office of the Attorney General.

“We’re reviewing the ruling and considering an appeal as well as a motion to stay the injunction,” says OAG spokesperson Robert Marus. “this ruling is opposed to a ruling in a different case on the same constitutional question, which a separate federal judge handed down in March.”

A.G. Karl Racine has since come out with a statement confirming he will appeal the judge’s decision. “We believe that the District’s gun laws are reasonable and necessary to ensure public safety in a dense urban area, and we will request a stay of this decision while we appeal.”
