Washington (CNN) - The Supreme Court agreed Monday to confront another high-profile challenge to affirmative action in college admissions.
The justices will decide the constitutionality of a voter referendum in Michigan banning race- and sex-based discrimination or preferential treatment in public university admission decisions.
The high court is currently deciding a separate challenge to admissions policies at the University of Texas, which did not involve a voter referendum.
A federal appeals court last year concluded the affirmative action ban, which Michigan voters passed in a 2006 referendum, violated the U.S. Constitution's equal protection laws.
It was the latest step in a legal and political battle over whether the state's colleges can use race and gender as a factor in choosing which students to admit. The ban's opponents say classroom diversity remains a necessary government role.
