Judge Frank Easterbrook, of the U.S. Court of Appeals for the Seventh Circuit, is known for two things: First, he writes some of the crispest, liveliest opinions that the federal bench has seen in decades. Second, he has absolutely no tolerance for nonsense. Both of these traits were on display yesterday, in the Seventh Circuit’s newest opinion in NRA v. Chicago.

Previously, the Supreme Court confirmed that the Second and Fourteenth Amendments prohibit state or local laws from infringing on the right to keep and bear arms, wholly rejecting Chicago’s attempt to preserve its gun possession law. That decision, issued by the Supreme Court, was an irrevocable loss for Chicago. And the city plainly recognized that: just four days after the Court’s issued its decision, Chicago repealed its gun law, yet replaced it with another one.
