State of California v. Superior Court

In State of California v. Superior Court (1984) 150 Cal. App. 3d 848, the Court held that where a statute commands an investigation, the scope and manner of the investigation is discretionary. There, the failure to revoke a license was immunized, even assuming such failure proximately caused damages of the kind sought to be avoided by the statute that authorized or commanded the investigation. (Id. at pp. 857-859 & fn. 8.)
