LANSING, Mich. (AP) -- The Michigan Legislative Black Caucus is expected to announce a lawsuit challenging portions of the new boundaries approved for districts in the state Legislature.
A press conference has been scheduled for Thursday at a National Association for the Advancement of Colored People office in Detroit.
The lawsuit's primary emphasis will be state House districts, according to Democratic Rep. Thomas Stallworth III of Detroit.
Democrats are upset that maps approved by the Republican-led Legislature and signed into law by Republican Gov. Rick Snyder would force incumbent state lawmakers from Detroit to run against each other in 2012.
It was not clear late Wednesday how or if the suit might address districts representing Michigan in the U.S. House.
