Parties are entitled to disclosure of all matter material and necessary to prosecution of the action. Any matter which may lead to admissible proof is discoverable, as is any matter which bears upon a defense, even if the facts themselves are not admissible. The test is one of usefulness and reason. A party asserting that material sought in disclosure is privileged bears the burden of demonstrating that the material it seeks to withhold is immune from discovery. Personnel records are discoverable where the plaintiff alleges a cause of action to recover damages for negligent hiring, retention, or supervision.
