The Michigan Supreme Court has heard arguments in a challenge to a proposed November ballot initiative to change who draws congressional and legislative districts every decade.
The justices held a special session Wednesday and asked many questions during 75 minutes of arguments.
The proposal would empower an independent commission to handle redistricting instead of the Legislature, now controlled by Republicans. Critics say the current process results in partisan gerrymandering that hurts democracy.
A group backed by the Michigan Chamber of Commerce says the constitutional amendment is too broad and proposes a general revision that can only be considered at a constitutional convention. Voters Not Politicians says its proposal addresses a single subject.
The state appeals court ordered the initiative on the ballot. Election officials want a ruling by early August.
