The University of Michigan has won a significant decision in a lawsuit challenging a campus ban on guns.
The state appeals court says the university can regulate the possession of guns. In a 2-1 opinion, the court says a 2001 ban doesn't violate the U.S. Constitution.
The court also says the Ann Arbor school and its other campuses aren't covered by a state law that prevents local governments from putting limits on guns.
Judge David Sawyer disagreed. He says the university is exceeding its authority by adopting its own restrictions.
