CPLR 2001 may not be used to disregard the plaintiff's failure to properly serve the defendants with process. The court's application of CPLR 2001 presupposes that the court has acquired jurisdiction. Thus, CPLR 2001 may be used to cure only a technical infirmity in service. In deciding whether a defect in service is merely technical, courts must be guided by the principle of notice, that is, whether service is reasonably calculated to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections. Defendant's actual receipt of process is not dispositive of the efficacy of service.
