the ground that the Commission action was not “arbitrary” and that appellant’s election under § 76 “with knowledge of all the facts” to appeal to the Commission precluded his maintaining the court action. The Supreme Court, Appellate Division, unanimously affirmed on the same ground of election of remedies and additionally grounded its affirmance on the lapsing of the applicable four-month statute of limitations for Article 78 actions. Taylor v. New York City Transit Authority, 25 A.D.2d 682, 269 N.Y.S.2d 75, 76 (2d Dep’t 1966). The Appellate Division, however, was not quite as firm on the issue of plaintiff’s “knowledge” regarding Scannell’s participation in the Authority’s dismissal proceedings:
“We additionally find that petitioner knew, or should have known, at the time of his appeal to the Civil Service Commission, that Commissioner Scannell had taken part ” Id.*
The judgment was unanimously affirmed without opinion by the New York Court of Appeals. Taylor v. New York City Transit Authority, 19 N.Y.2d 724, 279 N.Y.S.2d 181, 225 N.E.2d 886 (1967). Review was not sought in the United States Supreme Court. Instead, the present action was instituted in the District Court below.
Judicial Res Judicata
Section 76(3) of the New York Civil Service Law provides that “[t]he decision of such civil service commission shall be final and conclusive, and not subject to further review in any court.” The absolute language of this statutory subsection notwithstanding, however, New York courts have asserted jurisdiction over claims where state agency determinations under § 76 have been “purely arbitrary.” See, e. g., Trotman v. Hoberman, 56 Misc.2d 915, 290 N.Y.S.2d 680 (Sup.Ct.,Spee.Term, N.Y.Co.1968); Santella v. Hoberman, 29 A.D.2d 655, 286 N.Y.S.2d 647 (2d Dep’t 1968). The rationale underlying the assertion of judicial supervision over the proceedings of state agencies in such cases is that the New York legislature did not intend the words of the statute to be read in the absolute sense. Cf. Board of Educ. of City of New York v. Allen, 6 N.Y.2d 127, 136, 188 N.Y.S.2d 515, 520, 160 N.E.2d 60 (1959). However, in Taylor’s case, the Appellate Division, Second Department, refused to entertain appellant’s constitutional claim on the ground that the Commission’s determination of his case was not “purely arbitrary.”
Judge Weinstein apparently concluded that because New York courts dismissed for lack of jurisdiction and/or lapsing of the statute of limitations, there is no res judicata effect to be accorded the final state court judgment in appellant’s case. See 309 F.Supp. at 790. We disagree. While the state courts perceived themselves as powerless under § 76(3) to hear Taylor’s belated Article 78 due process claim, it was only because the due process claim was not raised in the first instance before the Commission that they could not do so. Had appellant prosecuted his constitutional objection in a timely manner, and had the Commission made an unsatisfactory disposition thereof, the courts of New York, in the exercise of their responsibility under the Supremacy Clause of the United States Constitution to entertain federal constitutional questions, no doubt would have taken jurisdiction of appellant’s case. Cf. Testa v. Katt, 330 U.S. 386, 67 S.Ct. 810, 91 L.Ed. 967 (1947); Amos Treat & Co. v. S. E. C., 113 U.S.App.D.C. 100, 306 F.2d 260 (1962); Trans World Airlines, Inc. v. C. A. B., 102 U.S.App.D.C. 391, 254 F.2d 90 (1958). It is in this sense that we find that the state courts made a final determination on the “merits,” which, under the principle of res judicata, we should not disturb.
Collateral Estoppel
In any event, the pivotal issue on which appellant’s constitutional claim turns is the state of his knowledge as of the date of his § 76 Commission hearing. Appellant claimed before the New York courts, as he claims here, that he had no
