Appellate Court Can Exercise Its Own Discretion Re: Scope of Discovery, Even in the Absence of Abuse

The First Department determined, over a dissent, that Supreme Court had improperly restricted the discovery of software code.  The court explained its power to overrule the trial court in this regard and the underlying principle allowing broad discovery:

New York strongly encourages open and full disclosure as a matter of policy … . To that end, CPLR 3101(a) provides that “[t]here shall be full disclosure of all matter material and necessary in the prosecution or defense of an action.”

A trial court is vested with broad discretion in its supervision of disclosure … . Indeed, “deference is afforded to the trial court’s discretionary determinations regarding disclosure” … . However, “[t]his Court is vested with the power to substitute its own discretion for that of the motion court, even in the absence of abuse” … . We have observed that we “rarely and reluctantly invoke” our power to substitute our own discretion for that of the motion court … . We find that this case presents one of those rare instances in which we are compelled to substitute our discretion for that of the motion court. MSCI Inc v Jacob, 2014 NY Slip Op 06239, 1st Dept 8-18-14
