The Michigan Supreme Court will hear arguments this week about whether a redistricting measure can go on the November ballot. It’s the last stop for the contentious proposal.

A Republican and business-backed group called Citizens Protecting Michigan’s Constitution disputed the proposal. They said the measure is a complete overhaul of the Constitution.

Dave Doyle is a spokesperson for the group.

“It creates in a sense, a fourth branch of government. So that’s a wholesale rewrite of the Constitution,” he says.

The Court of Appeals said the complaint against the proposal is “without merit.” But Citizens appealed to the Supreme Court.

Katie Fahey is with Voters Not Politicians, the group that spearheaded the proposal. She says hundreds of thousands of people have supported the measure.

“So it’s really a movement of, and for, and by the people of Michigan who just want to be able to vote on this in November,” she says.

The measure would create a commission of Republicans, Democrats and Independents to draw the state’s legislative district lines.
