University's Property Disposition Office is governmental function; employee immune from negligence

Mohammed Nawwas purchased a salad bar from the University of Michigan Property Disposition Office.  A university employee was using a fork lift to move the salad bar, when it fell and struck the plaintiff's arm, rupturing his left bicep tendon.  Nawwas filed a "tort" or personal injury action against the University and the fork life operator, but the claim was dismissed due to governmental immunity.  The Court of Appeals upheld the dismissal on appeal, noting that there was no proof of "gross negligence" by the employee and that the Property Disposition Office's functions did not generate the type of profit that would render it a proprietary function rather than a governmental function.
