A 9th Circuit panel upheld the roster, and the plaintiff is appealing to SCOTUS. The plaintiff is represented by Alan Gura. Cert petitions are due on December 31, 2018, and the court will decide in the spring whether to grant cert.

Update: the case has been distributed for the justices' April 12 conference.

Update June 11, 2019: there have been no updates since the case was distributed for the April 12 conference. The case is very possibly being held pending the result of New York State Rifle & Pistol Association v. City of New York. If that's what's happening, then once the ruling on that case comes out (in spring 2020), the justices will either decide on cert in this case or kick this case back down to the lower court to be re-decided in accordance with whatever the ruling in NYSRPA v. City of New York is.
