The DeKalb County district attorney sought a declaratory judgment against magistrate judges over whether hearsay alone could establish probable cause at preliminary hearings. The trial court declared that the judges had to admit and weigh hearsay, and the Court of Appeals affirmed. The Georgia Supreme Court reversed. It held that declaratory judgment was unavailable because the judges were neutral decision makers, not adverse parties, and the dispute arose from evidentiary rulings in criminal proceedings rather than a justiciable civil controversy. The State also could not use a civil label to circumvent the limited statutory right to appeal criminal rulings. The Court further concluded that existing case law already supplied whatever guidance the district attorney claimed to need, and the newly enacted Evidence Code would expressly provide that hearsay is admissible at preliminary hearings. The majority noted that the State could pursue additional evidence, a new prosecution, or a grand-jury indictment on a case-by-case basis. Justice Nahmias concurred, agreeing with the result while discussing legislative remedies and judicial discipline for systemic incompetence or bad faith. Judgment reversed.
