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.I didn’t need a law degree to see this coming. I needed three justices who kept saying so out loud. When the Court passed on a challenge to Maryland’s version of the ban last year, Justice Clarence Thomas wrote separately that he would not wait to decide whether the government can ban the most popular rifle in America. Justice Brett Kavanaugh predicted the Court would take up the question within a term or two. Justices Samuel Alito and Neil Gorsuch said they would have granted review right then. Four votes are what it takes to add a case to the docket. The Court just proved it had them, and it only took a year to prove it.
