CINCINNATI (AP) — A special three-judge panel focused on issues of camping, protests, free speech and executive power on Monday during arguments in an appeal of a lawsuit brought by Occupy Nashville protesters arrested on War Memorial Plaza in October 2011.

The panel hearing the case in at the U.S. 6th Circuit Court of Appeals in Cincinnati and made up of judges from around the country questioned whether Tennessee officials acted properly in imposing a last-minute curfew for the plaza and in arresting those who refused to leave War Memorial Plaza in Nashville in October 2011.
