Note: Under federal law, a three-judge federal trial court hears constitutional challenges to federal or state legislative districts or requests for preclearance, and these decisions are appealed directly to the U.S. Supreme Court. Federal appellate courts therefore tend to get involved only when there is no constitutional challenge or judicial preclearance request, or when only local districts are challenged.
Shapiro v. Mack, No. 1:13-cv-03233 (D. Md.), No. 14-1417 (4th Cir.) & No. 14-990 (S. Ct.): a challenge in federal court to the congressional map based on the "essentially non-contiguous structure and discordant composition" of the districts, which the court construed as a partisan gerrymandering claim.

The decision was affirmed on appeal; on June 8, 2015, the U.S. Supreme Court granted plaintiffs' petition for cert., for the 2015 Term. The Supreme Court will hear the issue of whether the case should have been sent to a three-judge court, rather than being dismissed by a single judge; the merits of the challenge will not be heard at this stage.
