The Supreme Court closed its term last week by opening the one every Second Amendment lawyer in the country has been waiting for.

On June 30, the justices granted certiorari in Viramontes v. Cook County, consolidated with a companion case out of Connecticut, and agreed to decide whether the Second and Fourteenth Amendments protect the right to possess AR-15-platform rifles and similar semi-automatic firearms. Oral argument comes this fall. A ruling should land by next spring. And when it does, it won’t stay contained to two jurisdictions. Close to a dozen states, including New York, California, and New Jersey, have versions of the same ban on the books, and every one of them is now waiting on what the Court decides in Chicago’s backyard.
