Whether a trial court may compel the defense to produce a defense investigator's notes of a witness interview for prosecutorial use when no statute authorizes the discovery.
Holding
No. Courts may not compel production of defense testimonial material for prosecutorial discovery absent explicit legislative authorization.
Reasoning
The court traced California's uncertain discovery doctrine from Jones v. Superior Court, through Prudhomme v. Superior Court, Reynolds v. Superior Court, and Allen v. Superior Court. Although Prudhomme suggested that some limited defense discovery might be permissible if disclosure could not possibly incriminate the accused, Reynolds counseled against judicial creation of prosecutorial-discovery procedures because of their difficult constitutional implications.
The lower appellate courts had developed conflicting approaches to defense-witness statements. Some permitted discovery for impeachment after judicial screening; others treated the witness's testimony as a waiver; still others concluded that even impeachment material may be incriminating because it can help secure a conviction. That conflict demonstrated why piecemeal judicial rulemaking was unsuitable.
Compelled discovery of defense material raises interconnected state self-incrimination, federal due-process reciprocity, right-to-counsel, attorney-client, work-product, and statutory-privilege concerns. A rule that opens defense files when the defendant or a defense witness testifies could chill thorough investigation and penalize the most diligent defense lawyers.
The Legislature, rather than the courts, must initially decide whether and how to create a comprehensive discovery regime. Any resulting statute would remain subject to constitutional review. The court therefore disapproved this order and other judicially created prosecutorial-discovery orders concerning defense testimonial evidence, while leaving intact established rules permitting compelled production of nontestimonial physical evidence.
