The Supreme Court has broad discretion in supervising disclosure and resolving discovery disputes. Pursuant to CPLR 3126, a court may impose sanctions where a party refuses to obey an order for disclosure or wilfully fails to disclose information which the court finds ought to have been disclosed. Although public policy strongly favors that actions be resolved on the merits, a court may resort to the drastic remedies of striking a pleading or precluding evidence upon a clear showing that a party's failure to comply with a disclosure order was the result of willful and contumacious conduct. The willful or contumacious character of a party's conduct can be inferred when, without a reasonable excuse, there is a repeated failure to respond to demands or to comply with the court's orders.
