In Bocanegra v. Jakubowski, published October 27, 2015, the Fourth District Court of Appeal, Division 2 affirmed the dismissal of the plaintiff's claims against an assistant district attorney for the plaintiff's imprisonment and the injuries he allegedly received during that imprisonment. Police officers arrested the plaintiff based on a bench warrant for a person with a similar name. The plaintiff alleged that the defendant assistant DA had information that would show that the plaintiff was wrongfully imprisoned, but did not investigate whether he was the wrong person or turn over the exculpatory information to the plaintiff's defense attorney. When the plaintiff appeared before a judge, he was freed.
The appellate court agreed with the trial court that the assistant DA was statutorily immune from all causes of action except false imprisonment. Government Code section 821.6's prosecutorial immunity applied to those causes of action. The court majority disagreed with the trial court's conclusion that section 821.6 applied to the false imprisonment cause of action. It held that section 821.6 does not apply to a false imprisonment claim that a lawfully arrested prisoner was imprisoned past the time he should have been freed due to negligence of a prosecutor. The majority ruled, however, that the statutory immunity did not preempt the common law immunity that applies to judicial officers and those involved in the judicial process. By prosecuting the action, the assistant DA was acting as a judicial officer. He was thus entitled to common-law immunity. A concurring justice opined that section 821.6 should have immunized the DA from liability under all of the causes of action.
