In Randle v. City and County of San Francisco (1986) 186 Cal. App. 3d 449, the plaintiff charged the public employees with suppression of evidence in a criminal case. The court held recovery of damages was precluded by the immunity provisions of section 821.6. ( Id. at p. 455.) It stated: "That the complaint alleges improper conduct regarding the evidence does not alter the fact that the acts alleged fall within the scope of employment. To hold otherwise would mean that an impropriety which provides a basis for liability would also provide a basis for vitiating immunity from such liability, thus making a mockery of section 821.6." ( Id. at p. 457.)
