Groups wanting to stop the spread of casinos in Michigan say they'll file a lawsuit to try to halt a fall referendum that would allow more gambling halls.
The lawsuit by a group called Protect MI Vote says the ballot question is illegal because it would change the Michigan Constitution and state law. The group plans to ask the Michigan appeals court Wednesday to block the secretary of state from approving petitions submitted by another group called Citizens for More Michigan Jobs.
Opponents of casino expansion are American Indian tribes and others who own casinos in Detroit and elsewhere in Michigan.
Backers of the casino referendum include ex-House Speaker Rick Johnson and ex-legislator and state budget director Mitch Irwin. Spokeswoman Emily Palsrok says the critics just don't want competition.
