On November 21, a 3-judge U.S. District Court struck down Wisconsin’s 2011 redistricting plan for the Assembly, the lower house of the legislature. Whitford v Gill, w.d., 3:15cv-421. Here is the opinion, which was 2-1. The opinion is by Judge Kenneth F. Ripple, a Reagan appointee. It is co-signed by Judge Barbara Crabb, a Carter appointee. The dissent, which is 40 pages, is by Judge William Griesbach, a Bush Jr. appointee.
The plaintiffs are voters who identify with the Democratic Party. Because this was a 3-judge court, the state’s only appeal is to the U.S. Supreme Court, which is very likely to accept the case. Thanks to Rick Hasen for the link.
