While discovery determinations rest with the sound discretion of the motion court, the Appellate Division is vested with corresponding power to substitute its own discretion for that of the trial court, even in the absence of abuse of discretion. Here, the Appellate Division declined to disturb the motion court's determination. Plaintiff failed to demonstrate that its discovery requests would yield information that was material and necessary to its defense against the counterclaims asserted against it.
