Where plaintiff violated the court's conditional order of preclusion by failing to produce a witness for a scheduled deposition, and failed to demonstrate either a reasonable excuse for the failure to comply or a meritorious claim, the court may deny plaintiff's motion to allow the deposition to proceed. The court is not required to find that the failure to comply was willful.
