Plaintiffs were injured at a nightclub shooting that occurred during a rap concert featuring performers from rival gangs. Plaintiffs sued the nightclub’s owner on claims for negligence per se and strict liability on an ultrahazardous activity theory. This opinion affirms summary judgment for defendants on both claims. The defendants’ alleged violation of certain provisions of a conditional use permit to operate the nightclub did not support the negligence per se claim because the permit was not designed to prevent the type of injuries that plaintiffs sustained. Hosting a rap concert, even one with performers from rival gangs, is not an ultra-hazardous activity.
