The resolution of discovery disputes is within the sound discretion of the motion court. Striking a pleading may be appropriate where there is a clear showing that the failure to comply with discovery demands is willful or contumacious, pursuant to CPLR 3126[3]. Willful and contumacious conduct may be inferred from a party's repeated failure to comply with court-ordered discovery, coupled with inadequate explanations for the failures to comply, or a failure to comply with court-ordered discovery over an extended period of time.
