In Datil v. City of Los Angeles (1968) 263 Cal.App.2d 655, the court rejected the plaintiffs' contention that the Tort Claims Act violated due process by granting an immunity from liability for torts to subordinate public entitles, which would result in unequal protection of the laws. The court noted that in all cases which had challenged the act to date, all had upheld its constitutionality. ( Id., at pp. 660-661.)
