OPINION

The plaintiff pro se, Warren William Bohn, purports to state a claim under 42 U.S.C. § 1983; two defendants, the State of New York and the City of New York,1 have moved pursuant to Rule 12(b)(6) of the Federal Rules of Civil Procedure (“Rules”) to dismiss that claim.2 For the following reasons the motion is granted. The ground for dismissal, however, is lack of subject matter jurisdiction in this Court. See Rule 12(b)(1).

From the scant record available, the facts — taking them as true for the purposes of this motion to dismiss — are as follows: In 1955 the plaintiff was arrested for a New York State Vehicle and Traffic Law offense. He was then just under twenty *28years of age. He was jailed and found guilty, and was sentenced to a $50.00 fine or thirty days in jail, all without benefit of counsel and all the while prevented from communicating with his parents. He served one week of the sentence. His parents finally located him and paid the fine to secure his release. Now, some twenty-three years later, the plaintiff is apparently a prisoner serving a twenty-five year sentence for murder in Florida.3 Complaint, Exhibit B. For no articulated reason other than an allusion to the discrimination in employment which might result from the besmirching of his record with this earlier arrest, the plaintiff has sued to have the 1955 judgment and sentence vacated and the arrest record expunged.4

Indeed, the plaintiff has sued twice for the same relief. Exhibit B to the complaint appears to be an unofficial copy of a Memorandum and Order (No. 436382) issued by the Supreme Court of the State of New York, County of New York (Leff, J.) denying the vacatur of this judgment. The denial is summary and without explanation, other than to state that the application is “without merit.”5 What the exhibit reveals to this Court, however, is that the plaintiff correctly applied to the sentencing court for vacatur, employing the New York procedural counterpart of the ancient writ of coram nobis. See N.Y.C.P.L. §§ 440.10 & 440.30. Coram nobis, in both state and federal courts, is the proper way to attack the constitutionality of a conviction where the sentence has been completely served. United States v. Forlano, 319 F.2d 617, 618 & n.1 (2d Cir. 1963). However, it is well established that such a petition must be made before the court of conviction and sentence and that no other court has jurisdiction to hear it. Sanchez Tapia v. United States, 338 F.2d 416 (2d Cir. 1964) (per curiam), cert. denied, 380 U.S. 957, 85 S.Ct. 1096, 13 L.Ed.2d 974 (1965). It follows, therefore, that it will not do to label an action a “civil rights” complaint, as does this plaintiff, in order to avoid the trial court’s denial of a coram nobis petition, and this must be true whether or not such petition for vacatur is based on the alleged deprivation of constitutional rights.

This Court is unable to locate any case directly on point; however, the best analogy to be drawn is from precedential treatment of other prisoner complaints alleging civil rights violations. In Preiser *29v. Rodriguez, 411 U.S. 475, 500, 93 S.Ct. 1827, 36 L.Ed.2d 439 (1973), the Supreme Court determined that habeas corpus — not section 1983 — was the exclusive remedy for a prisoner challenging the “fact or duration” of his imprisonment. The rationale supporting this decision is to

avoid the unnecessary friction between the federal and state court systems that would result if a lower federal court upset a state court conviction without first giving the state court system an opportunity to correct its own constitutional errors.

Id. at 490, 93 S.Ct. at 1836. That policy applies with equal force to the requirement that the court of conviction and sentence review a petition to vacate judgment, for in such proceedings the exprisoner is likewise challenging the “fact” of his former imprisonment. Therefore, the civil rights law cannot be-a substitute for coram nobis, any more than it is for habeas corpus. Moreover, when a state coram nobis petition has been turned away at the trial level, the only remedy is appeal in the state system, for neither does the civil rights law permit “a second bite at the cherry” in federal court. Lackawanna Police Benevolent Ass’n v. Balen, 446 F.2d 52, 53 (2d Cir. 1971).

Because the Court’s theory of dismissal departs from that of the defendants on this motion to dismiss, reference should be made to the Rule 12(b)(6) arguments proffered. They have been confused from the start. The defendants originally moved for dismissal on grounds that the City of New York was not a “person” within the meaning of section 1983 and that the State of New York was immune from suit under the protection of the eleventh amendment. The latter argument is quite correct, Edelman v. Jordan, 415 U.S. 651, 94 S.Ct. 1347, 39 L.Ed.2d 662 (1974); Stenson v. State of New York, 422 F.Supp. 38 (S.D.N.Y. 1976). However, with respect to the City of New York, the defendants’ argument was vitiated by the decision of the Supreme Court in Monell v. Department of Social Services, 436 U.S. 658, 98 S.Ct. 2018, 56 L.Ed.2d 611 (1978) (local governments not wholly immune from suit, under section 1983). Consequently, by Memorandum and Order dated June 14, 1978, this Court ordered the defendants to rebrief their argument in light of Monell. Instead, the defendants switched gears, and in a new motion (mooting the grounds of the old) they urged that section 1983 was inapplicable because the complaint was actually a habeas corpus petition that was barred for failure to exhaust state remedies. As the plaintiff has not been in custody on this offense in twenty-three years, that contention is absurd. Thus the correct response vis-a-vis the State of New York, i. e., immunity, was no longer before the Court, and a totally inapposite argument vis-a-vis both defendants took its place.6 However, the making of the motion to dismiss put the sufficiency of the complaint at issue, and the jurisdictional defect became apparent. It is hornbook law that a court has the right and obligation to determine its own jurisdiction. Skidmore v. Syntex Laboratories, Inc., 529 F.2d 1244, 1248 n.3 (5th Cir. 1976). Therefore, this Court having no subject matter jurisdiction to hear a petition coram nobis on a New York State judgment, the complaint is dismissed.

So ordered.
