A federal appeals court is about to consider a lawsuit challenging Michigan's ban against racial preferences in public university admissions and government hiring.

Civil rights groups and University of Michigan students, faculty and applicants say the 2006 ballot measure approved by voters is unconstitutional.

Critics say the constitutional amendment has created an unfair process where universities give weight to geographical diversity and legacy status but not racial identity.

Supporters say the law reflects the will of the people.

Arguments will be held Tuesday morning at the 6th U.S. Circuit Court of Appeals in Cincinnati. A district judge dismissed a challenge to the law last year.
