On August 22, the Michigan Republican Party filed a federal lawsuit against the new Michigan redistricting commission. Michigan Republican Party v Benson, w.d., 1:19cv-669. The case is assigned to U.S. District Court Judge Janet T. Neff, a Bush Jr. appointee.
The complaint says the party does not oppose the idea of a redistricting commission, but it objects to the Michigan commission because it calls for four Republican members, four Democratic members, and five members who are neither. The Republican Party says that commission members self-identify with their party. Michigan does not have registration by party. The lawsuit argues that if the Republican Party is going to be represented by four commissioners, then the party should have input into who those four Republicans will be.
