Pursuant to CPLR 3126, a court may impose discovery sanctions, including the striking of a pleading or preclusion of evidence, where a party refuses to obey an order for disclosure or willfully fails to disclose information which the court finds ought to have been disclosed. The nature and degree of the penalty is a matter within the discretion of the motion court. However, the Appellate Division is vested with its own discretion and corresponding power to substitute its own discretion for that of the trial court, even in the absence of abuse.
Public policy strongly favors the resolution of actions on the merits whenever possible. Thus, before a court invokes the remedy of precluding evidence, there must be a clear showing that the failure to comply with discovery was willful and contumacious. The willful or contumacious character of a party's conduct can be inferred from the party's repeated failure to respond to demands or to comply with discovery orders, and the absence of any reasonable excuse for its failures.
