A state judge has dismissed a lawsuit challenging the University of Colorado Board of Regents' ban on carrying concealed weapons on the system's campuses, The Colorado Springs Gazette  reported. The suit was brought by three students who said that relevant state law protected their right to carry concealed weapons. But the judge ruled that their legal argument was based on a false assumption that the university system should be considered a locality. Rather, the judge ruled, the Board of Regents has state-granted authority as a state agency, and was within its rights to ban the carrying of concealed weapons. The Colorado ruling comes at a time of increased activism -- with significant legislative support in some states  -- against campus gun bans.
