MOORE, Circuit Judge:
Plaintiffs are property owners in Belle Harbor, a seaside section of Queens, New York. Aggrieved by a decision of the Building Department of the City of New York to grant an alteration permit to a builder in the area permitting the conversion of an existing building into a multiple dwelling, they sought to have the permit revoked as contrary to New York law. Their struggles led to a long course of litigation in the courts of the State of New York and, most significantly, to the dismissal of their appeal on constitutional grounds by the New York Court of Appeals “upon the ground that no substantial constitutional question [was] directly involved”. Ellentuck v. Klein, 39 N.Y.2d 743, 384 N.Y.S.2d 1030 (1976). Plaintiffs did not seek review from the Supreme Court of the United States, but rather commenced the instant civil rights action in the federal district court for the Southern District of New York, asserting four separate causes of action against several groups of the principals in the New York land use dispute. The district court dismissed the entire complaint with prejudice on the grounds of res judicata, collateral estoppel, and “principles of federal-state comity”. It is from this order of dismissal that plaintiffs appeal. A meaningful analysis of appellants’ claims is only possible after a more detailed description of the prior proceedings.
I.
On June 14, 1972, defendant Kimball Construction Company (“Kimball”) purchased a three-story-and-basement wood frame building located on Rockaway Beach Boulevard, Belle Harbor, from the Sisters of Reparation of the Congregation of Mary, Inc. Over a period of some twenty years, the Sisters had used the premises as a con[417] vent, primarily as a home for homeless and/or aged women. At the time the building was purchased by Kimball, it contained approximately 24 bedrooms, 10 bathrooms, a large dining room, a commercial kitchen, a laundry room, and a garage.
Prior to making the purchase, neighborhood resident John Kimball, an officer of Kimball Construction Company and an individual defendant in this suit, reviewed records on file at the Queens office of the New York City Department of Buildings.1 According to those records, the building had previously been accepted as a Class “B” multiple dwelling (rooming house) and an alteration application submitted in 1950 showed “existing legal use” as a “Class ‘B’ Heretofore Converted Dwelling”.2
On or about June 30, 1972, John Kimball filed plans with the Department of Buildings in order to obtain a permit to convert the premises to a Class “A” multiple dwelling (apartment house for permanent residents). The proposed conversion was seemingly permitted under the New York City Zoning Resolution, even in the R2 Zoning District (single family detached residences) encompassing the Belle Harbor area, since a Class “B” multiple dwelling constituted a nonconforming use and the Resolution provided for alteration from one nonconforming use to another nonconforming use. New York City Zoning Resolution § 52-61, effective December 15, 1961.
Thus, plans submitted by Kimball were approved pursuant to instructions from Er-ling Karlsen,3 Inspector for the Department of Buildings for the Borough of Queens, and on November 17, a construction permit was issued by Borough Superintendent H. Irving Sigman, a defendant in the first cause of action. Pursuant to the permit, work was commenced on the conversion of the building into a dwelling which was to contain 14 apartments plus an apartment for a superintendent.
Shortly thereafter, the Belle Harbor Property Owners Association, Inc., sought to have the permit invalidated. Several of their representatives met with Borough Superintendent Sigman and with then-Commissioner of Buildings of the City of New York, Joseph Stein,4 to discuss the propriety of revoking the permit. Sigman, by interdepartmental memorandum to Stein, expressed his opinion that the plans had been properly approved, stating that the dwelling had been accepted as a Class “B” multiple dwelling since 1945 and recorded as such in the records of the Department. Sigman also expressed his belief that the resulting condition (i. e., the existence of a multiple dwelling in a neighborhood zoned for one-family residences) might be undesirable, but that, since the conversion seemed in all respects consistent with the law, the issuance of the permit was a matter “over which we have no control”.5
After further communications among all concerned, Stein notified the President of the Property Owners Association that the request to revoke the permit was being denied, but that, as a result of the objections, he was directing that the entire building be equipped with sprinklers and that each dwelling unit be provided with a second means of egress.
Still dissatisfied, the adjacent landowners decided that legal proceedings should be instituted to vindicate their interests.6 At [418] that time there existed legal impediments to suing as an association in the State of New York. Hence, several of the landowners in the area joined in an application to the New York Supreme Court, Queens County, to obtain a declaration that the permit was void.7 The defendants named in the State court suit were Stein as the Building Commissioner, Sigman as the Borough Superintendent, Karlsen as the Buildings Department Examiner, and Kimball Construction Company.
In the State suit, the plaintiffs attempted to prove that, despite the Building Department Records’ indication that the subject building was a Class “B” multiple dwelling, that nonconforming use had been abandoned8 because the previous owners of the building, the Sisters of Reparation of the Congregation of Mary, Inc., had used the building as a convent;9 and given the abandonment which resulted in a conforming use, the new owner had lost the right to maintain the nonconforming use and could not convert the premises to a second nonconforming use under the Zoning Resolution.
After denial of a temporary stay preventing construction, a non-jury trial was held; the complaint was dismissed on the ground that the prior use had been conforming, as indicated by the Building Department records. The property owners appealed.
During the pendency of the appeal, Kim-ball completed the conversion process and received a certificate of occupancy as a Class “A” multiple dwelling and several tenants moved in. On April 29, 1974, approximately one and one-half months after the certificate of occupancy was issued, and at a time when five tenants were residing in the building, the Appellate Division, Second Department, reversed on the law and on the facts. The appellate court stated that it
“[f]ound the evidence overwhelming (e. g., Sisters’ testimony, tax exemptions, combustible permit fee exemption, 1968-1969 telephone directory, other documents, etc.) that from approximately 1951 to 1972 the Sisters operated the premises as a convent and, on a charitable non-profit basis, primarily as a home for homeless and/or aged women. This usage is a conforming usage under R-2 classification (detached residences) imposed by the zoning ordinance resolution that became effective in December 1961. [W]e find that the evidence clearly established that the Class B classification was clearly abandoned by the Sisters’ conforming usage from 1952 until the 1972 transfer to Kimball and that, in any event, in view of the character of the neighborhood, the nature of the conversion, and the dismal assessment of the conversion by Borough Superintendent Sigman of the Department of Buildings of the City of New York, on December 8, 1972, the 1972 alteration permit permit[419] ting the conversion should not have been granted.” Ellentuck v. Stein, 44 A.D.2d 714, 714-15, 354 N.Y.S.2d 705, 707 (2d Dept. 1974).
The decision, which ended with a declaration of nullity of the permit and which ■enjoined further construction under the permit, was not appealed.
Based on the decision of the Second Department, Building Commissioner Jeremiah T. Walsh (who succeeded Stein in that position), by letter dated May 17, 1974 (Joint App. at 99A), directed Superintendent Sig-man to apply to the Board of Standards and Appeals (“BSA”) for revocation of the certificate of occupancy. A letter dated June 11, 1974 requesting revocation was sent by Sigman to the BSA. (JA at 100A).
The BSA set the matter for hearings and, on or about October 1, 1974, approximately five months after the Appellate Division decision, revoked the certificate of occupancy-
II.
The second stage of the dispute commenced at this juncture. About three weeks after the certificate of occupancy was revoked, Kimball applied to the BSA for a variance on grounds of “hardship” pursuant to Section 72-21 of the Zoning Resolution of the City of New York,10 asking for permission to maintain and operate the building as a class “A” multiple dwelling. The Chairman of the Community Planning Board # 14, the local community board having jurisdiction in the area, was notified of the request for the variance. The Planning Board had its own public hearing, and subsequently notified the BSA that it was making no recommendation at all on the subject. The BSA then held hearings on three dates (January 29, February 18, and March 11, 1975), after notice was sent to property owners residing within 400 feet of the property, in accordance with the rules of procedure of the BSA. At the hearings, extensive evidence was presented, much of it informally as is customary in such proceedings. Some 83 adjacent landowners filed objections to the granting of the variance; 11 adjoining landowners submitted consent forms to the BSA requesting that the variance be granted. The owners of the two houses directly adjoining the subject building supported the variance.11
After the somewhat heated hearings, the BSA granted the variance, conditioned on the reduction of the number of residential units to eleven, plus one caretaker’s unit. Three of the five members of the BSA voted in favor of the variance; one voted to deny, and one did not participate.
On March 27, 1975, just two days after the BSA granted the variance, the property owners instituted a proceeding under Article 78 of the New York Civil Practice Law & Rules (CPLR), seeking to annul the variance. After the proceeding was transferred to the Appellate Division, Second Department, pursuant to CPLR § 7804(g), the court confirmed the order of the BSA and dismissed the proceeding on the merits. Ellentuck v. Klein, 51 A.D.2d 964, 380 N.Y.S.2d 327 (2d Dept.1976). In its opinion, the court affirmed the BSA’s finding that Kim-ball was entitled to relief from “unnecessary hardship”, rejecting petitioners’ argument -that the BSA was foreclosed from [420] granting the variance by virtue of the earlier decision of that court which had annulled the building permit. That earlier decision, stated the court,
“related solely to the propriety of the issuance of the alteration permit. . The fact that some of the issues before the board were discussed on an arguendo basis in this court’s prior decision did not preclude the board’s intensive consideration of those factors, based upon additional evidence (including a personal inspection of the premises and neighborhood), and its conclusion that those factors were not as ‘dismal’ as they had appeared to be in the earlier proceeding . . . and, further, that they were outweighed by the elements of hardship.” 51 A.D.2d at 964, 380 N.Y.S.2d at 329.
On March 10, 1976, the petitioners filed a notice of appeal as of right to the New York Court of Appeals, asserting that there were constitutional questions involved. Kimball moved to dismiss.
III.
While the appeal was pending, petitioners learned that Honorable Henry J. Latham, one of the Appellate Division Justices who had participated in the decision confirming the action of the BSA, was a trustee of the Richmond Hill Savings Bank, which, as mortgagee on the Kimball mortgage for the building, had intervened in the BSA proceedings. Richmond had represented to the BSA that it would be irreparably damaged if the variance were denied, and had pointed out that it had acted in good faith reliance on a search and the report of its title insurance company, which confirmed that the property had been “classified in Department of Buildings as a Heretofore converted Class B Rooming House (28 Rooms). No Certificate of Occupancy required — None issued”. This letter was one of the many pieces of evidence which had been before the BSA when it made its decision on the variance.
After the petitioners learned of Justice Latham’s tie to the bank, they filed an affidavit with the New York Court of Appeals detailing the relationship and contending that, because of the relationship, the decision in which Justice Latham had participated, although unanimous, was rendered void.12
On April 6, 1976, the New York Court of Appeals, responding to Kimball’s motion, dismissed the appeal “on the ground that no substantial constitutional question was directly involved”. Ellentuck v. Klein, 39 N.Y.2d 743, 384 N.Y.S.2d 1030 (1976).
Petitioners also moved in the Appellate Division to vacate the court’s March 1, 1976 decision. On April 27, 1976, the Second Department granted the motion to the extent of permitting reargument and adhered to its original decision. Justice Latham again sat on the panel, but he did not participate in the vote.
Petitioners then sought leave to appeal to the New York Court of Appeals, but their motion was denied on May 6, 1976. Ellentuck v. Klein, 39 N.Y.2d 707, 385 N.Y.S.2d 1026 (1976). They also filed an appeal as of right — on constitutional grounds — from the order of the Appellate Division after reargument, specifically challenging, inter alia, the propriety of Justice Latham’s participation in the proceedings. That appeal was dismissed sua sponte by the New York Court of Appeals, again upon the ground that no substantial constitutional question was directly involved. Ellentuck v. Klein, 40 N.Y.2d 844, 387 N.Y.S.2d 1034 (1976).
Petitioners did not seek certiorari from the United States Supreme Court. Rather, they filed a motion in the Queens County Supreme Court, Special Term, requesting an order vacating the final judgment entered in that court. The court, per Justice Lerner, denied the motion, stating that “[t]he decisions upon which this judgment is predicated, having been reviewed by the Court of Appeals, are binding upon this court and leave it no discretion whatever in the matter”. Ellentuck v. Klein, No. [421]*4213754/75 (Supreme Court Queens County, July 23, 1976).
IV.
After the decision of the Queens County Supreme Court, plaintiffs abandoned the State forum. They brought the instant action' in the federal district court for the Southern District of New York, alleging that the actions of the various Building Department officials, the members of the Board of Standards and Appeals, Kimball Construction Company and its officers, the Appellate Division Justices, and Supreme Court Justice Lerner had violated their civil rights. Jurisdiction was claimed to exist under the substantive provisions of 42 U.S.C. §§ 1983 and 1985(3) and their jurisdictional counterpart, 28 U.S.C. § 1343.13 Given the history of the State litigation and the dismissal by the State’s highest court for lack of a substantial constitutional question, the district judge dismissed the entire complaint on the ground of res judicata, collateral estoppel, and comity, holding that “the federal, state, local and administrative claims made by the plaintiffs here were thoroughly litigated in the state forum”. As to the second and third causes of action, we agree with the district court’s conclusion. The first and fourth causes of action require further analysis, and we discuss these several claims separately.
V.
THE SECOND AND THIRD CAUSES OF ACTION
In plaintiffs’ second cause of action, they name the following persons as defendants: the three members of the BSA who voted in favor of the variance, John B. Walsh, Philip Agusta, and Henry M. Carrol, all individually; Kimball Construction Company and [422] its officers, John and Marie A. Kimball; Richmond Hill Savings Bank, Kimball’s mortgagee; and Julius Granirer, an attorney for and trustee of the Richmond Hill Savings Bank who, according to plaintiffs, drew up the mortgage for Kimball’s loan and also represented Kimball on that deal. The gist of this cause of action is that the named defendants “entered into a purposeful scheme and conspiracy and conspired together at various times and places to violate the provisions of the Zoning Law of the City of New York, the Multiple Dwelling Law of the State of New York and the Constitution of the United States . . .” by favoring the interests of defendant Kim-ball. Amended Complaint, ¶ 86, JA at 20A.
According to plaintiffs, the Multiple Dwelling Law of the State of New York prohibits the action taken by the Board of Standards and Appeals. To make their point, plaintiffs make reference to various provisions of the Multiple Dwelling Law, the New York City Charter, and the Zoning Resolution of the City of New York, as well as to the Administrative Code of the City of New York, all relating to the powers of the BSA with respect to wooden frame structures. It is alleged that these provisions were violated by the joint and willful efforts of the various defendants — and that, in furtherance of the alleged conspiracy: the Kimballs filed the application for the variance and later claimed to have made great expenditures; the members of the BSA permitted unsworn evidence to be offered, much of it ex parte ; the Richmond Hill Bank intervened in the proceedings by its letter which was accepted ex parte by the BSA; and the BSA did not require audited statements of expenditures made by Kimball — all to the detriment of plaintiffs’ rights to due process and equal protection. 'Apart from the conspiracy claims, then, the second cause of action attacks the procedures that were followed in granting the variance and the result that obtained. Plaintiffs ask for damages of $1 million, and a declaration that the BSA’s order granting the variance is void, as well as an injunction restraining the BSA from re-granting a variance.
The third cause of action is directed against the five justices of the Appellate Division who confirmed the BSA’s grant of the variance, and against Supreme Court Justice Lerner, who refused to order undone that which the New York Court of Appeals had reviewed. After detailing the history of the actions taken by those courts and the alleged “interest” of Justice La-tham, plaintiffs requested that the federal court declare the decisions of the Appellate Division and the Supreme Court, Queens County, to be void on the ground that due process of law was denied by virtue of the participation of Justice Latham in the procedure.
The papers before the court make it abundantly clear that the due process arguments and the challenge to Justice Latham’s participation were vigorously presented to the New York Court of Appeals.14 It is equally clear that, as a legal matter, a dismissal by the New York Court of Appeals for want of a substantial constitutional question is “tantamount to a dismissal of the constitutional issues on the merits,” Turco v. Monroe County Bar Association, 554 F.2d 515, 521 (2d Cir.), cert. denied, - U.S. -, 98 S.Ct. 122, 54 L.Ed.2d 95 (U.S. 1977) (No. 76-1816); [423] McCune v. Frank, 521 F.2d 1152, 1155 (2d Cir. 1975), and is thus determinative of the issues actually raised and litigated, either by way of res judicata or collateral estop-pel.
Plaintiffs, however, urge that we must not give res judicata or collateral estoppel effect to the New York Court of Appeals’ dismissal in this case. They argue that Article 78 of the New York CPLR, under which the BSA’s decision was reviewed, places a strict limitation on the questions that can be considered by a New York court reviewing agency action15 — and that matter which was not before the agency may not be considered at all. They support their argument by reference to decisions of the New York Court of Appeals which have warned that the constitutionality of legislative enactments cannot be questioned in an Article 78 proceeding. E. g., Friedman v. Cuomo, 39 N.Y.2d 81, 382 N.Y.S.2d 961, 346 N.E.2d 799 (1976); Merced v. Fisher, 38 N.Y.2d 557, 381 N.Y.S.2d 817, 345 N.E.2d 288 (1976); Kovarsky v. Housing and Development Administration, 31 N.Y.2d 184, 335 N.Y.S.2d 383, 286 N.E.2d 882 (1972). Given these pronouncements, plaintiffs argue, the New York Court of Appeals could not have exercised jurisdiction to review their claims of denial of due process, nor of the disqualification of Justice Latham, because both claims presented “additional facts and documents not part of the certified record of proceedings held before the Board of Standards and Appeals”. Brief for Appellants at 35.
If the New York Court of Appeals lacked jurisdiction to render a constitutional decision on the merits, we must of course, accept plaintiffs’ arguments that res judicata and collateral estoppel are inapplicable, and their failure to seek review from the Supreme Court of the United States would be of no moment. But that is simply not the case here.
In Matter of Kovarsky v. Housing and Development Administration, supra, 31 N.Y.2d 184, 335 N.Y.S.2d 383, 286 N.E.2d 882 (1972), the New York Court of Appeals was faced with a constitutional challenge to the enactment under which the respondent agency had acted. The matter was before the court under Article 78 of the New York CPLR — the same provision as was used by the Belle Harbor plaintiffs to attack the decision of the BSA. The New York Court of Appeals, while declaring that constitutional challenges should normally be brought by way of an action for a declaratory judgment, nonetheless proceeded to the merits, treating the proceeding as a declaratory judgment action under the power conferred by CPLR § 103(c) (McKinney 1972). The Kovarsky principle represented the view of the New York Court of Appeals that a court “should not become involved in drawing fine lines of distinction in characterizing the form in which relief is sought”, 31 N.Y.2d at 192-93, 335 N.Y.S.2d at 388, 286 N.E.2d at 886, and has been followed, e. g., Port Chester Electrical Construction Corp. v. Edythe Atlas, 40 N.Y.2d 652, 389 N.Y.S.2d 327, 357 N.E.2d 983 (1976); New York Public Interest Research Group, Inc. v. Steingut, 40 N.Y.2d 250, 254 n.1, 386 N.Y.S.2d 646, 353 N.E.2d 565 (1976); Matter of Fritz v. Huntington Hospital, 39 N.Y.2d 339, 347, 384 N.Y.S.2d 92, 348 N.E.2d 547 (1976), in cases where all necessary parties were before the court and the constitutional matters had been briefed. See also Lombard v. Board of Education of the City of New York, 502 F.2d 631, 637 (2d Cir. 1974). Thus, if the “necessary parties” were before the New York courts, jurisdic[424] tion existed under CPLR § 103(c) to render a decision on the constitutional questions actually litigated.
We must consider, then, who, in fact, were the parties affected by the constitutional issues raised by the Belle Harbor property owners, and whether they were before the New York Court of Appeals.
Chapter 27 of the New York City Charter relates to the powers of the Board of Standards and Appeals. Section 666(2) of that Chapter confers power on the BSA, after public hearings (see § 665(c)):
“[t]o make, amend and repeal rules and regulations for carrying into effect the provisions of the laws, resolutions, rules and regulations in respect to any subject-matter, jurisdiction whereof is conferred by law on the board, and to include in such rules and regulations provisions applying to specific conditions and prescribing means and methods of practice to effectuate such provisions and for carrying into effect the powers of the board.”
Among the powers of the Board is the power to grant variances pursuant to the provisions of the Zoning Resolution of the City of New York, effective December, 1961. Section 72-01(d) of that Resolution also vests power in the BSA to “adopt, amend, or repeal” its own rules of procedure after public hearings. Pursuant to its power to grant variances, the BSA has indeed adopted its own procedures, and is thus the responsible party in a case, such as this, where the procedural fairness of its rule is questioned. The BSA was the respondent in the Article 78 proceeding, represented by the Corporation Counsel of the City of New York. Thus, the “necessary party” criterion for conversion of the proceeding to a declaratory judgment action was satisfied.16 Any due process claim with respect to the procedures of the BSA that was actually litigated was thus resolved against the Belle Harbor plaintiffs, and they cannot be heard to litigate the same cause a second time.
The same is true as to Justice Latham’s participation. Moreover, it is clear that under New York law, if a judge is disqualified, that disqualification strips the court of subject matter jurisdiction. Wilcox v. Supreme Council of Royal Arcanum, 210 N.Y. 370, 104 N.E. 624 (1914). If, in this case, the Appellate Division had no jurisdiction to make a determination in the Article 78 proceeding because it lacked subject matter jurisdiction, that defect would be raisable at any time during the proceeding, even, as in this case, for the first time on appeal. See MacAffer v. Boston & Maine R.R., 268 N.Y. 400, 404, 197 N.E. 328 (1935); Deile v. Boettger, 250 App.Div. 633, 295 N.Y.S. 115 (2d Dept. 1937). Obviously, when the matter was raised before the New York Court of Appeals and the Appellate Division (on reargument), those courts had the jurisdiction to determine if jurisdiction did, in fact, exist. See CPLR § 3211(a)(2) (McKinney 1970). Thus, we believe that the Appellate Division properly considered the question of its own jurisdiction and that the New York Court of Appeals necessarily decided the question when it considered the decision below and, instead of dismissing for lack of jurisdiction, cf., Friedman v. Cuomo, 39 N.Y.2d 81, at n.*, 382 N.Y.S.2d 961, 346 N.E.2d 799, citing Matter of Merced v. Fisher, 38 N.Y.2d 557, 381 N.Y.S.2d 817, 345 N.E.2d 288, found no constitutional question to exist. The matter has been finally resolved against plaintiffs herein.17
[425] We find, in sum, that under the Kovarsky rationale, the constitutional questions that were raised were fully litigated and decided adversely to the Belle Harbor property owners. It follows, then, that were they dissatisfied with the adjudication, their proper course was to seek review by the Supreme Court of the United States. This they did not do.
We have, in the recent past, had many occasions to reaffirm the salutary policies underlying the doctrines of res judicata and collateral estoppel, e. g., Expert Electric, Inc. v. Levine, 554 F.2d 1227 (2d Cir.), cert. denied, — U.S. -, 98 S.Ct. 300, 54 L.Ed.2d 190 (U.S. 1977) (No. 77-218); Turco v. Monroe County Bar Association, supra, 554 F.2d 515 (2d Cir.), cert. denied, - U.S. -, 98 S.Ct. 122, 54 L.Ed.2d 95 (U.S. 1977) (No. 76-1816); Mitchell v. National Broadcasting Co., 553 F.2d 265 (2d Cir. 1977), and we see no need to reiterate those principles in this case. See also Thistlethwaite v. City of New York, 497 F.2d 339 (2d Cir.), cert. denied, 419 U.S. 1093, 95 S.Ct. 686, 42 L.Ed.2d 686 (1974); Tang v. Appellate Division, 487 F.2d 138 (2d Cir. 1973), cert. denied, 416 U.S. 906, 94 S.Ct. 1611, 40 L.Ed.2d 111 (1974). Suffice it to say, as we did in the Mitchell case, supra, 553 F.2d at 272, that the applicability of the doctrine “does not depend on whether the prior judgment was free from error”, contrary to plaintiffs’ assertions. Indeed, even as to a claim termed a federal civil rights violation, “[f]ederal courts do not sit to review the determinations of state courts”, id. at 273, whose judges are as beholden to the Constitution as are we, as federal judges. Since the due process matters in the second and third causes of action were fully adjudicated, and since plaintiffs failed to seek Supreme Court review, neither the district court nor this court should nullify the determination of the New York Court of Appeals. Rooker v. Fidelity Trust Co., 263 U.S. 413, 44 S.Ct. 149, 68 L.Ed. 362 (1923).18
Two further matters must be addressed, however, before we can dispose of the second cause of action. The first concerns the claim that in this federal action, there are two named plaintiffs who were not named petitioners in the Article 78 proceeding, and that, therefore, they cannot be barred from raising the claims in federal court. Curiously, plaintiffs themselves failed to raise this point at the district court level and on appeal until after it was raised by the “Municipal Appellees”. Rather, in their amended complaint, plaintiffs aver that they are suing “for themselves as the owners of property adjacent to the subject premises . . . and for other adjacent property owners . . . ” — i. e., as a class of property owners whose association paid all the legal fees and disbursements of the State proceedings. See Appellant’s Brief at 4; footnote 7 supra. Indeed, in their main brief to this court, they characterize themselves as the petitioners in the Article 78 proceeding. E. g., Appellant’s Brief at 25.
This court has recently had occasion to address itself to the issue of the lack of true “identity” of parties in the context of a claim of res judicata. In Expert Electric, Inc. v. Levine, supra, 554 F.2d at 1233, Chief Judge Mishler of the Eastern District of New York, sitting by designation, wrote for the court that identity “is a factual determination of substance, not mere form. . Generally speaking, one whose interests were adequately represented by another vested with the authority of representation is bound by [a prior] judgment, al[426] though not formally a party to the litigation”. In Expert Electric, the court found various contractors barred by res judicata because the trade associations to which they belonged had adequately represented the collective interests of the individual participants in prior litigation based on the same factual predicate. We think that the Expert Electric rationale is equally applicable to the instant case, and we hold that all plaintiffs in the case at bar, according to their own self-characterization, were represented by the Belle Harbor Property Owners’ Association, as they are in this case. They are thus estopped from litigating the due process issue anew.
The second matter that need be addressed concerns plaintiffs’ claim, in their second cause of action, of a conspiracy between the named defendants to violate their rights to due process and equal protection of the laws. Admittedly the conspiracy aspect was not raised before the New York Court of Appeals, and appellants attempt to bring themselves within the ambit of federal civil rights jurisdiction by alleging a conspiracy under 42 U.S.C. § 1985(3). We reject the allegations as vague and conclusory, showing no more than a history of State court litigation that resulted in a decision adverse to plaintiffs’ interests.
One of the major cases dealing with § 1985(3) was decided by this court in 1964. In Powell v. Workmen's Compensation Board, 327 F.2d 131 (2d Cir. 1964), plaintiff, disappointed by the result of Workmen’s Compensation Board hearings, charged a civil rights conspiracy among the various principals to the hearings. As in this case, the allegations in the complaint detailed the course of the State litigation, concluding that a conspiracy must have been afoot for such a result to have obtained. This Court affirmed the dismissal of the matter, stating:
“A complaint in a case like this must set forth facts showing some intentional and purposeful deprivation of constitutional rights. Snowden v. Hughes, 321 U.S. 1, 64 S.Ct. 397, 88 L.Ed. 497 (1944). This complaint does contain some general allegations, framed in broad language closely paralleling that used in [section] . . 1985(3), that defendants successfully conspired to deprive plaintiff of his rights. But plaintiff was bound to do more than merely state vague and conclu-sionary allegations respecting the existence of a conspiracy. It was incumbent upon him to allege with at least some degree of particularity overt acts which defendants engaged in which were reasonably related to the promotion of the claimed conspiracy. . . . The allegations contained in the complaint indicate no more than the action of several interested parties to a workmen’s compensation proceeding, who sought vigorously to protect their own interests, coupled with the normal administrative processes of adjudication and appeal. Indeed, were we to hold this complaint sufficient, we would be inviting every party to a state proceeding ... to file a complaint in this court reciting the history of his state case and concluding with a general allegation of conspiracy. Moreover, with respect to plaintiff’s claimed deprivation of equal protection, he has not even alleged any discrimination essential to a denial of this right.” 327 F.2d at 137 (emphasis added).
We think the instant case is fully governed by Powell. There is nothing in the complaint or in any of the numerous affidavits and papers before the court to suggest any concerted action by the defendants. Nor can the property owners of Belle Harbor claim to be a “class” against whom discrimination was practiced because of their membership in the class, for the purpose of equal protection analysis. Indeed, none of the allegations rise to the level of “racial, or perhaps otherwise class-based, invidiously discriminatory animus,” allegation of which is necessary to sustain a § 1985(3) action. Griffin v. Breckenridge, 403 U.S. 88, 102, 91 S.Ct. 1790, 1798, 29 L.Ed.2d 338 (1971).
In sum, we find that insofar as the second and third causes of action raise due process claims which might otherwise be [427] actionable under 42 U.S.C. § 1983 — and we indicate no view on the merit of that contention — we are precluded by the doctrines of res judicata, collateral estoppel, and comity from addressing ourselves to plaintiffs’ assertions. Insofar as conspiracy under 42 U.S.C. § 1985(3) is alleged, it is insufficiently supported to require further proceedings. We affirm the dismissal of those two counts.
VI
THE FOURTH CAUSE OF ACTION
In plaintiffs’ fourth cause of action, interposed solely against the BSA, there appear to be two different claims. First, certain allegations address the procedures for the conduct of hearings established by the BSA pursuant to its authority to make its own rules, i. e., the New York City Charter, the Administrative Code of the City of New York, and the Zoning Resolution of the City of New York, effective December, 1961. As in the papers before the New York Court of Appeals,19 plaintiffs mount a due process challenge to those procedures’ informality, specifically: The provisions permitting service of notice of hearings on mortgagees instead of owners of property; the lack of requirement that witnesses be sworn; the limited availability of cross-examination and rebuttal; the BSA’s acceptance of ex parte evidence; the unavailability of subpoena power by which plaintiffs could obtain the variance applicant’s books and records to rebut the claimed expenditures; and the tardiness in this case of the BSA’s mandatory statement of its findings of fact to support the variance grant. After making these allegations, plaintiffs then aver that the procedures are standard practice, and that they permit the deprivation of property without due process of law. They ask that the rules and regulations of the BSA be declared void.
Insofar as the fourth cause of action challenges the BSA procedures on due process grounds, we affirm the dismissal of the complaint on the ground of res judicata for the same reasons that the due process allegations of the second cause of action can no longer be raised. The issues were conclusively litigated in the New York Court of Appeals which, under its Kovarsky doctrine, could convert the Article 78 proceeding into an action for a declaratory judgment. As in the second cause of action, the party responsible for the allegedly unconstitutional action — here, the BSA, promulgator of its own rules and regulations — was before the court and its action vis-a-vis plaintiffs was determined to pose no constitutional problems. Plaintiffs may not relitigate the issue.
However, there is a second prong to the fourth cause of action. Paragraph 175 of the amended complaint alleges
“that those portions of the New York City Charter, Administrative Code of the City of New York, the Zoning Resolution of the City of New York and the rules and regulations for the conduct of hearings adopted by the Board of Standards and Appeals, which either by express statute or rule, or by failure to enunciate proper guidelines, permit deprivation of valuable property rights of plaintiffs and others without due process of law, are unconstitutional and void.”
As we construe the pleading, aside from the attack on the self-made rules of the BSA, which is barred by the prior litigation, plaintiffs are alleging that there was an impermissible delegation of power to an agency of the City, unlawful because of its lack of adequate standards. As to this claim, the party responsible for the challenged enactments — i. e., the City of New York — was not technically a party to the Article 78 proceeding.20 Thus, the Kovar-sky doctrine would not necessarily have permitted adjudication of the issue.
We need not decide this delicate question of New York jurisdiction, however, [428] for even if the delegation issue could never have been litigated in a hypertechnical sense,21 and even if plaintiffs are not barred from now raising it,22 it does not, standing alone, state a claim cognizable under 42 U.S.C. § 1983.
The concept of the separation of governmental powers, which underlies any claim of improper delegation, rises to a federal issue only as to the federal government. The organization of the governments of the various states is a matter of state (constitutional) law. See Friedman v. Beame, 558 F.2d 1107, 1111 (2d Cir. 1977), citing Sweezy v. State of New Hampshire, 354 U.S. 234, 77 S.Ct. 1203, 1 L.Ed.2d 1311 (1957). It is true that at times, an improper delegation under state law may rise to the level of a due process violation and implicate federal constitutional standards. Sweezy v. State of New Hampshire, supra, 354 U.S. 234, 77 S.Ct. 1203; see also City of Eastlake v. Forest City Enterprises, Inc., 426 U.S. 668, 93 S.Ct. 2358, 49 L.Ed.2d 132 (1976). To the extent that federal constitutional values are involved in the case at bar, however, we are still without subject matter jurisdiction to consider the claim, for the simple reason that the City of New York is, as noted, the proper defendant in an action to annul its enactments. While amendment of the complaint might be properly permitted in a case where a necessary party is not before the court, it would not confer jurisdiction in this case, for, under 42 U.S.C. § 1983 and its jurisdictional base, 28 U.S.C. § 1343, a city is not a “person” within the meaning of § 1983, irrespective of whether the relief requested is legal or equitable. Monroe v. Pape, 365 U.S. 167, 81 S.Ct. 473, 5 L.Ed.2d 492 (1961); City of Kenosha v. Bruno, 412 U.S. 507, 93 S.Ct. 2222, 37 L.Ed.2d 109 (1973). Thus, even if federal claims may be involved, and even if plaintiffs may still assert those claims, a federal district court is powerless to resolve them under the Civil Rights Act.23 We therefore affirm the dismissal of [429] that portion of the fourth cause of action which attacks the New York City Charter, the Administrative Code of the City of New York, and the Zoning Resolution of the City of New York on the ground that, even assuming federal constitutional rights are implicated, the district court lacks subject matter jurisdiction with respect to those challenges.
VII.
THE FIRST CAUSE OF ACTION
Plaintiffs’ first cause of action relates solely to the facts detailed in Part I of this opinion, and concerns only the initial grant of the building permit by various officials of the New York City Department of Buildings. Defendants in this action are Kimball Construction Co. and its officers; and H. Irving Sigman, Borough Superintendent, both in his official capacity and individually.24
Plaintiffs argue that both Kimball and Sigman “knew or should have known” that the permit was illegal under state law; and that their continued efforts to circumvent the law, especially after the validity of the proposed conversion was challenged, constituted a denial of due process and equal protection. The wrongdoing, plaintiffs contend, should be actionable as a violation of the Civil Rights Act because, were it not for Kimball’s expenditures made possible only because of the construction undertaken pursuant to an invalid permit, Kimball would never have been able to prove his right to a variance on grounds of unnecessary hardship. Were it not for the permit, plaintiffs argue, the value of their property would not have been depreciated.
It is urged that this cause of action was erroneously held barred by the district judge because the constitutional questions raised in the Article 78 proceeding dismissed by the New York Court of Appeals concerned only the variance — not the permit.
We hold, however that, regardless of whether a wrong was committed under state law, no civil rights claim is stated in the first cause of action for the reason that no constitutionally protected “property” interest was infringed by the actions of the named defendants.
Property interests are
“of course . . . not created by the Constitution. Rather, they are created and their dimensions are defined by existing rules or understandings that stem from an independent source such as state law — rules or understanding that secure certain benefits and that support claims of entitlement to those benefits.” Board of Regents v. Roth, 408 U.S. 564, 577, 92 S.Ct. 2701, 2709, 30 L.Ed.2d 181 (1972), quoted in Paul v. Davis, 424 U.S. 693, 709, 96 S.Ct. 1155, 47 L.Ed.2d 405 (1976).
Under New York law, the source of plaintiffs’ property rights, a landowner has no vested interest in the existing classification of his property. Shepard v. Skaneateles, 300 N.Y. 115, 89 N.E.2d 619 (1949). Indeed, a zoning ordinance which changes a particular district, if a rational and proper exercise of the police power, Euclid v. Ambler Realty Co., 272 U.S. 365, 47 S.Ct. 114, 71 L.Ed. 303 (1926), does not offend the Constitution as a “taking” of property; rather, it sets forth the “rules and understandings” which define the property interests of those affected by the ordinance — interests which, when so defined, would be entitled to constitutional protection.
Again under New York law, no right to a nonconforming use is gained when a landowner applies for a permit, nor even when an illegal permit is issued. See Matter of Jayne Estates v. Raynor, 22 N.Y.2d 417, 422, 293 N.Y.S.2d 75, 239 N.E.2d 713 (1968); B. & G. Construction [430] Corp. v. Board of Appeals, 309 N.Y. 730, 128 N.E.2d 287 (1955). Thus, by Kimball’s receipt of the invalid permit, neither Sigman nor Kimball effectuated a change of the status of Kimball’s interest, nor an irreversible change in the relationship between the respective rights of Kimball and the other Belle Harbor property owners as to the use of their property. No interest or expectation was irreparably altered or extinguished at that point in time,25 see Paul v. Davis, 424 U.S. 693, 711, 96 S.Ct. 1155, 47 L.Ed.2d 405 (1976), as is evidenced by plaintiffs’ initial success in their effort to have the permit voided. What plaintiffs really decry is the result of the variance — a matter they can no longer litigate.
Yet, plaintiffs would have us hold that federal jurisdiction exists to impose liability on Sigman and Kimball because of their alleged willfulness and indifference to New York law and to plaintiffs’ rights thereunder. They state that there was a conspiracy afoot to favor Kimball, to deny them their rights to keep their neighborhood intact: that Kimball was permitted to begin construction even before the permit was issued; that Sigman knew that the apartment building proposed by Kimball would be out of keeping with the neighborhood; and that the various delays on the part of Building Department officials indicated bad faith as to plaintiffs’ rights.26
While we do not foreclose the possibility that tortious conduct may have been present, be it intentional or negligent, we cannot agree that this dispute is one cognizable under the Civil Rights Act. Speaking of the scope of § 1983 and of the fourteenth amendment, the Supreme Court, in its recent decision in Paul v. Davis, 424 U.S. 693, 700, 96 S.Ct. 1155 (1976), quoted the Court’s earlier decision in Screws v. United States, 325 U.S. 91, 109, 65 S.Ct. 1031, 89 L.Ed. 1495 (1945), wherein Justice Douglas observed that in enacting the criminal provisions of the Civil Rights Act, Congress did not intend “to make all torts of state officials federal crimes”. Nor was the fourteenth amendment intended to be a “font of tort law to be superimposed upon whatever systems may already be administered by the States”. Paul v. Davis, supra, 424 U.S. at 701, 96 S.Ct. at 1160; Jones v. Marshall, 528 F.2d 132 (2d Cir. 1975).
In the case at bar, we are not dealing with allegations of unfair and discriminatory conduct purposefully directed toward plaintiffs which, historically, has been held to state a civil rights action. See Burt v. City of New York, 156 F.2d 791 (2d Cir. 1946) (sustaining civil rights action under predecessor to § 1983 and § 1985(3) against BSA and other persons associated with Building Departments when it was alleged that defendants “selected [plaintiff] for . oppressive measures”). See also, e. g., Cordeco Development Corp. v. Santiago Vasquez, 539 F.2d 256 (1st Cir. 1976) (impermissible political considerations entered into officials’ decisions); But see id. at 260 n.5, suggesting that the matter is not settled. And contrary to plaintiffs’ vague and conclusory assertions of conspiracy, inadequate facts are alleged to suggest concerted action actually intended to effectuate a violation of plaintiffs’ interests or a devaluation of their property because of their membership in a class or otherwise. Snowden v. Hughes, 321 U.S. 1, 64 S.Ct. 397, 88 L.Ed. 497 (1944); Powell v. Work[431] men’s Compensation Board, supra, 327 F.2d 131 (2d Cir. 1964).
We decline to intercede in this essentially state affair and to extend the Civil Rights Act beyond its outermost intendments.27 See South Gwinnet Venture v. Pruitt, 491 F.2d 5 (5th Cir.) (en banc), cert. denied, 419 U.S. 837, 95 S.Ct. 66, 42 L.Ed.2d 64 (1974).
We thus affirm the dismissal of the first cause of action. Such dismissal, however, will not affect any action that may exist under state law.
The order and judgment entered thereon dismissing the amended complaint are affirmed.
