Snyder

MEMORANDUM *

Adam Snyder and Jade Santoro appeal the district court’s grant of summary judgment in favor of the City and County of San Francisco (“the City”) and former Deputy Chief of Police Alex Fagan, Sr. Plaintiffs filed suit against Defendants under 42 U.S.C. § 1983 . Plaintiffs allege that Defendants are liable for the off-duty conduct of Officers Alex Fagan, Jr., David Lee, and Matthew Tonsing (“the officers”), who physically assaulted Snyder and Santoro on November 20, 2002 over a bag of steak fajitas. Plaintiffs allege that the City is liable under Monell v. Department of Social Services, 436 U.S. 658 , 98 S.Ct. 2018 , 56 L.Ed.2d 611 (1978), due to the San Francisco Police Department’s policy or custom of inadequate disciplinary procedures. Plaintiffs allege that Fagan, Sr. is liable in his individual capacity because his conduct as a supervisor bears a sufficient causal link to the actions of the officers. Defendants moved for summary judgment and the district court granted the motion.
