(Subscription required) Reversing an appellate court decision, the state Supreme Court denied prosecution immunity Thursday to Riverside County sheriff’s deputies from a lawsuit by the widow of a man who was shot and killed by a neighbor and whose body was left exposed for hours. The ruling only addressed one of the county’s defenses, but one that has been successfully employed by state government agencies in a host of lawsuits over the years: absolute immunity under Government Code Section 821.6.
