Following Saelzler v. Advanced Group 400 (2001) 25 Cal.4th 763, this decision affirms summary judgments in favor of the companies that owned the parking lot around the 49ers’ stadium and provided security there on game days. One fan punched the plaintiff twice in the face, dropping him to the ground and seriously injuring him, in response to plaintiff’s having kicked a beer bottle inadvertently striking the assailant’s car. Plaintiff could not establish a non-speculative theory of causation–i.e., that any negligence in providing adequate security caused plaintiff’s injuries which were suffered in a 2-3-minute interval with no forewarning.
