This post provides an update on last week's developments in Cooke et al. v. Hickenlooper. This is a lawsuit filed May 17 in federal District Court in Denver, challenging two gun laws enacted by the state legislature in March. In the case, I represent 55 of Colorado's 62 elected Sheriffs, plus one retired police officer. Other plaintiffs, with their own attorneys, include the Colorado Farm Bureau, Outdoor Buddies (which helps disabled people participate in outdoor sports), the Colorado Outfitters Association (trade association for hunting guides), federally licensed firearms dealers, the National Shooting Sports Foundation, and others. We argue that House Bill 1224 (magazine ban) and House Bill 1229 (background checks and paperwork on temporary loans and private sales of firearms) violate the Second and Fourteenth Amendment, and the Americans with Disabilities Act.
