As the majority notes, although other methods of service were available to them, in commencing this action grounded in negligence, strict products liability, and breach of warranty, the plaintiffs relied on Business Corporation Law § 307, which in pertinent part designates the Secretary of State as an imputed agent for service on a foreign corporation unauthorized to do business in New York (Business Corporation Law § 307 [a]; see, Flick v Stewart-Wamer Corp., 76 NY2d 50, 56). Jurisdiction may thus be acquired over a foreign corporation unauthorized to do business New York, such as the appellant, by personal delivery of process and payment of a statutory fee to the Secretary of State at the office of the Department of State followed by specified steps "calculated to assure that the foreign corporation, in fact, receives a copy of the process” (Flick v StewartWamer Corp., supra, at 56), i.e., by delivery of process personally to the foreign corporation outside the State or by sending process to the foreign corporation "by registered mail with return receipt requested, at the post office address specified for the purpose of mailing process, on file in the department of state, or with any official or body performing the equivalent function * * * or if no such address is there specified * * * to the last address of such foreign corporation known to the plaintiff” (Business Corporation Law § 307 [b] [2]).
Where mailing to the foreign corporation is used "proof of service shall be by affidavit of compliance with this section filed, together with the process, within thirty days after receipt of the return receipt signed by the foreign corporation * * * If a copy of the process is mailed in accordance with this section, there shall be filed with the affidavit of compliance * * * the return receipt * * * Service of process shall be complete ten days after such papers are filed with the clerk of the court” (Business Corporation Law § 307 [c] [2]). *9The plaintiffs here purportedly followed the steps set forth in Business Corporation Law § 307 in that someone acting on the plaintiffs’ behalf personally served a copy of the summons and complaint on the Secretary of State, and an affidavit to that effect is included in the record. Several days thereafter, someone acting on the plaintiffs’ behalf sent, by registered mail, return receipt requested, the summons, the complaint, and a notice that service of process was made on VWAG by delivery at the Department of State. An affidavit attesting to the mailing, as well as a copy of the return receipt, are also included in the record. Furthermore, the plaintiffs’ attorney asserted in opposition to the appellant’s motion to dismiss pursuant to CPLR 3211 (a) (8) that "proof of service” was filed with the "Clerk of the Court of Nassau County”, evidently on the thirtieth day after the plaintiffs’ attorney received the return receipt. However, although the plaintiffs specified on their summons, and were thus well aware that the appellant is domiciled and has a particular address in Germany, the required mailing was sent to an address in Englewood, New Jersey, "on behalf of’ VWAG, which address was that of the defendant Volkswagen of America, Inc. (hereinafter VOA), a New Jersey corporation which, like the appellant, is subject to the "long arm” jurisdiction of our courts. Additionally, no affidavit of compliance is included in the record and it appears that the "proof of service” which the plaintiffs assert but do not prove was filed with the "Clerk of the Court of Nassau County” consisted only of the two affidavits of service.
The plaintiffs urge here, as they did before Supreme Court, that VOA is a wholly owned subsidiary and the jurisdictional "alter ego” of the appellant, and that, therefore, service was properly effectuated on the appellant by serving VOA (see, Taca Intl. Airlines v Rolls-Royce of England, 15 NY2d 97). The appellant disputed VGA’s status as a mere instrumentality of it. However, it also claimed, as it does on appeal, that the relationship between it and VOA is, for jurisdictional purposes, irrelevant, because service was not effectuated in compliance with Business Corporation Law § 307. Ruling that the issue of whether VOA was the appellant’s agent for jurisdictional purposes had already been litigated and resolved against the appellant (see, Luciano v Garvey Volkswagen, 131 AD2d 253, 255; but see, Brandt v Volkswagen AG., 161 AD2d 1149; Derso v Volkswagen of Am., 159 AD2d 937; see also, Volkswagenwerk AG. v Schlunk, 486 US 694), the Supreme Court upheld service and denied the motion.
*10I note my disagreement with the majority’s conclusion that the plaintiffs are relieved by collateral estoppel principles of the burden of demonstrating by an appropriate factual showing that the appellant so controls VOA that the latter is for jurisdictional purposes its alter ego. Although some courts have, based on the facts before them and in accordance with then applicable law, resolved the issue against the appellant (see, Schlunk v Volkswagenwerk AG., 145 Ill App 3d 594, 503 NE2d 1045, affd on other grounds 486 US 694; see also, Luciano v Garvey Volkswagen, supra, at 255), courts in this State have also resolved the issue in VWAG’s favor (see, e.g., Brandt v Volkswagen AG., 161 AD2d 1149, supra; Derso v Volkswagen of Am., supra). It is my view that, given these conflicting rulings based on differing factual premises, collateral estoppel, a factual doctrine premised on principles of fairness (see, Kelly v Malone Frgt. Lines, 139 AD2d 566; Samhammer v Home Mut. Ins. Co., 120 AD2d 59, 60) cannot be used here to create a shortcut for the plaintiffs. In any event, while I disagree with this conclusion, I also regard it as irrelevant.
It is true, as the majority notes, that service on a parent corporation can be effectuated, and jurisdiction over the parent acquired, by service in accordance with a statutorily prescribed method on a wholly owned subsidiary (see, Taca Intl. Airlines v Rolls-Royce of England, supra; see also, ABKCO Indus. v Lennon, 52 AD2d 435) so long as the two entities are so closely associated that the subsidiary can be considered a mere department of the parent. Moreover, if certain other jurisdictional facts exist, neither the parent nor the subsidiary need be "present” in New York in order for service on a mere instrumentality to be jurisdictionally effective as to the parent (see, CPLR 313; see also, McHugh v International Components Corp., 118 Misc 2d 489). The majority ignores, however, that service here was not made directly upon the subsidiary but rather on the Secretary of State. Since, unlike corporations which are authorized to do business in New York, the Secretary of State is only the imputed or constructive agent of the foreign corporation unauthorized to do business in New York, "strict compliance with the procedures of Business Corporation Law § 307 is required” (Flick v Stewart-Warner Corp., supra, at 57). Such omissions as mailing by certified mail rather than registered mail and failing to file an affidavit of compliance have been ruled jurisdictionally fatal where service is made pursuant to Business Corporation *11Law § 307 (Flick v Stewart-Warner Corp., supra; see also, Nelson v Abbott Labs., NYLJ, Nov. 12, 1991, at 36, col 1 [Sup Ct, Nassau County, Wager, J.]). It is my view that similarly fatal flaws exist here.
There is virtually no evidence that the plaintiffs complied with the filing requirements set forth in Business Corporation Law § 307 (c) (2) (see, Nelson v Abbott Labs., supra; cf., Flick v Stewart-Warner Corp., supra). More significantly, it is clear that the address to which the plaintiffs sent the requisite mailing constituted neither an address specified by the appellant for service of process nor the "last address of such foreign corporation known to the plaintiff” (see, Business Corporation Law § 307 [b] [2]). Apart from the filing defects which it does not address, the majority here in effect equates service on a corporation pursuant to CPLR 311 (1) (cf., McHugh v International Components Corp., supra) with the service specially authorized by Business Corporation Law § 307. I disagree and conclude that where a plaintiff purports to rely on Business Corporation Law § 307 and elects to "assure that the foreign corporation, in fact, receives a copy of the process” (see, Flick v Stewart-Warner Corp., supra, at 56) by mailing the process documents, it may not do so in care of the address of a subsidiary corporation, even one which is a "mere instrumentality” of or otherwise serves as the jurisdictional alter ego of the foreign corporation (cf., Flick v Stewart-Warner Corp., supra; see, Newman v Searle & Co., 50 AD2d 574). To the extent that the decision of the Appellate Division, Third Department, in Luciano v Garvey Volkswagen (supra), decided before the Court of Appeals decision in Flick v Stewart-Warner Corp. (supra) is to the contrary, I would decline to follow it. Since I conclude that service here was not properly effectuated in accordance with the steps prescribed by Business Corporation Law § 307, it is my view that the appellant’s motion to dismiss pursuant to CPLR 3211 (a) (8) should have been granted.
Accordingly, I vote to reverse the order appealed from, on the law, and to grant the appellant’s motion to dismiss the complaint insofar as it is asserted against it for failure to properly effectuate service upon it.
