In Liberal v. Estrada, published January 19, 2011, the Ninth Circuit reviewed the defendant police officers' appeal from the district court's denial of their motion for summary judgment in a suit brought under 42 U.S.C. section 1983 and California state law causes of action. The suit arose out of an incident in which the officers detained the driver and passengers in a car for 45 minutes, searched the car, and allegedly used force against the driver. The ground for the detention and search was that the car had tinted side windows, in violation of California law. The driver, however, declared that the window on the side the police officers saw was rolled down.
The case addressed the question of whether denial of a summary judgment motion based on California Government Code section 820.2 (discretionary immunity) was immediately appealable. The majority opinion concluded that it was. Under federal procedural law, denial of summary judgment based on a state law immunity from suit is immediately appealable. If the immunity is from liability, rather than suit, it is not. The majority ruled that section 820.2 is an immunity from suit. Judge Tashima, in dissent, opined that section 820.2 was merely an immunity from liability.
The court also concluded that the district court correctly denied summary judgment based on section 820.2, because the immunity did not apply to causes of action for false arrest and imprisonment.
The court also upheld the district court's denial of summary judgment as to the section 1983 causes of action on the ground of qualified immunity. Issues of fact prevented the district court from concluding that the officers did not violate clearly-established law concerning the grounds for and length of detention, or the appropriate use of force.
