In Raschel v. Rish, 69 NY2d 694 [1986] the Court of Appeals held that, since the CPLR is "silent as to the number of copies of a summons and complaint that must be served on a person conceivably acting in more than one representative capacity, the guiding principle must be one of notice reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections'" (Raschel, 69 NY2d at 696-697." In any event, "when the requirements for service have not been met, it is irrelevant that a defendant may have actually received the documents" (Raschel at 697).
