What it's about

The Supreme Court dismissed its review as improvidently granted (ended review without deciding the legal questions).

The Court of Appeals for the Armed Forces had found Cox’s claims moot before the Supreme Court took the case.

Question presented

1. Whether this Court has jurisdiction to review the cases in Nos. 16-961 and 16-1017 under 28 U. S. C. § 1259(3)? 2. Whether the Court of Appeals erred in holding that Petitioners' claims were moot? 3. Whether these judges' service on the CMCR disqualified them from continuing to serve on the CCAs under 10 U.S.C. § 973(b)(2)(A)(ii)? 4. Whether the judges' simultaneous service on both the CMCR and the AFCCA violated the Appointments Clause?
