From the published per curiam opinion, People of the State of Michigan v. Craig Michael DeRoche (PDF):
This case presents a question of first impression, namely whether the Second Amendment to the United States Constitution precludes a prosecution for possession or use of a firearm by a person under the influence of alcoholic liquor, MCL 750.237, where the prosecutor’s theory is one of constructive possession in the defendant’s own home. We conclude that it does.
[T]he government cannot justify infringing on defendant’s Second Amendment right to possess a handgun in his home simply because defendant was intoxicated in the general vicinity of the firearm. Accordingly, the district court did not err in finding that MCL 750.237, as applied to defendant, was unconstitutional.
