In January 2018, Judge Wynn wrote the majority opinion for a three-judge panel which struck down North Carolina's congressional districts on grounds that the state's 2016 districting plan constituted a partisan gerrymander in violation of Article I of the Constitution, and the First and Fourteenth Amendments. After the Supreme Court vacated Judge Wynn's panel opinion for reconsideration in light of Gill v. Whitford, 138 S.Ct. 1916 (2018), Judge Wynn authored a revised majority opinion for the three-judge panel again finding that North Carolina's 2016 congressional districting plan violates the Constitution.
