delivered the opinion of the Court.

Appellee is an adult resident of Hartford) Wis. She brought suit in a federal district court in Wisconsin to have a Wisconsin statute declared unconstitutional.1 • A three-judge court was convened, 28 U. S. C. § 2281. That court, by a divided vote, held the Act unconstitutional, 302 F. Supp. 861, and we noted probable jurisdiction. 397 U. S. 985.

The Act, Wis. Stat. § 176.26 (1967), provides that designated persons may in writing forbid the sale or gift of intoxicating liquors to one who “by excessive drinking” produces described conditions or exhibits speci-’ fied traits, such as exposing himself or family “to want” or becoming “dangerous to the peace” of the community.2

*435The chief of police of Hartford, without notice or hearing to appellee, caused to be posted a notice in all retail liquor outlets in Hartford that sales, or gifts of liquors to appellee were forbidden for one year. Thereupon this suit was brought against the chief of police claiming damages and asking for injunctive relief. The State of Wisconsin intervened as a defendant on the injunctive phase of the case and that was the only issue tried and decided, the three-judge court holding the Act unconstitutional on its face and enjoining its enforcement, The court said:

“In ‘posting’ an individual, the particular city official or spouse is doing more than denying him the ability to purchase alcoholic beverages within *436the city limits. In essence, he is giving notice to the public that he has found the particular individual’s behavior to fall within one of the categories., enumerated in the statutes. It would be naive not-to recognize that such ‘posting’ or characterization of an individual will expose him to public embarrassment and ridicule, and it is our opinion that procedural due process requires that before one acting pursuant to State statute can make such a quasi-judicial determination, the individual involved must be given notice of the intent to post and an opportunity to present his side of the matter.” 302 F. Supp., at 864.

We have no doubt as to the power of a State to deal. with the evils described in the Act. The police power of the States over intoxicating liquors was extremely broad even prior to the Twenty-first Amendment. Crane v. Campbell, 245 U. S. 304. The only issue present here is whether the label or characterization given a person by “posting,” though a mark of serious illness to some, is to others such a stigma or badge of disgrace that procedural due process requires notice and an opportunity to be heard. We agree with the District Court that the private interest is such that those requirements of procedural due process must be met.

It is significant that most of the provisions of the Bill of Rights are procedural, for it is procedure that marks much of the difference between rule by law and rule by fiat.

We reviewed in Cafeteria Workers v. McElroy, 367 U. S. 886, 896, the nature of the various “private interest^]” that have fallen on one side or the other of the line. See also Sniadach v. Family Finance Corp., 395 U. S. 337, 339-342. Generalizations are hazardous as some state and federal administrative procedures are sum*437mary by reason of necessity or history. Yet certainly where the State attaches “a badge of infamy” to the citizen, due process comes into play. Wieman v. Updegraff, 344 U. S. 183, 191. “[T]he right to be heard before being condemned to suffer grievous loss of any kind, even though it may not involve the stigma and hardships of a criminal .conviction, is a principle basic to our society.” Anti-Fascist Committee v. McGrath, 341 U. S. 123, 168 (Frankfurter, J., concurring).

Where a person’s good name, reputation, honor, or integrity is at stake because of what the government is doing to him, notice and an opportunity to be heard are essential. “Posting” under the Wisconsin Act may to some be merely the mark of illness, to others it is a stigma, an official branding of a person. The label is a degrading one. Under the Wisconsin Act, a resident of Hartford is given no process at all. This appellee was not afforded a chance to defend herself. She may have been the victim of an official’s caprice. Only when the whole proceedings leading to the pinning of an unsavory label on a person are aired can oppressive results be prevented.

It is suggested that the three-judge court should have stayed its hand while the aggrieved person repaired to the state courts to obtain a construction of the Act or relief from it. The fact that Wisconsin does not raise the point does not, of course, mean that it lacks merit. Yet the suggestion is not in keeping with the precedents.

Congress could, of course, have routed all federal constitutional questions through the state court systems, saving to this Court the final say when it came to .review of the state court judgments. But our First Congress3 resolved differently and created the federal court system and in time granted the federal courts various heads of *438jurisdiction,4 which today involve most federal constitutional rights. Once that jurisdiction was granted, the federal courts resolved those questions even when they were enmeshed with state law questions. In 1941 we gave vigor to the so-called abstention doctrine in Railroad Commission v. Pullman Co., 312 U. S. 496. In that ease an authoritative resolution of a knotty state law question might end the litigation and not give rise to any federal constitutional claim. Id., at 501. We, therefore, directed the District Court to retain the suit pending a determination by a state court of the underlying state law question. We applied the abstention doctriné most recently in Fornaris v. Ridge Tool Co., ante, p. 41, where a relatively new Puerto Rican statute, which had not been authoritatively construed by the Commonwealth’s courts, “might be judicially confined to a more narrow ambit which would avoid all constitutional questions.” We ordered the federal courts to stay their hands until the Puerto Rican courts had spoken. Speaking of Reetz v. Bozanich, 397 U. S. 82, we noted that the “three-judge federal court should not have proceeded to strike down ah Alaská law which, if construed by the Alaska Supreme Court, might be so confined as not to have any constitutional infirmity.” Ante, at 43. But the abstention rule only applies where “the issue of state law is uncertain.” Harman v. Forssenius, 380 U. S. 528, 534. Thus our abstention cases have dealt with unresolved questions of state law which only a state tribunal could authoritatively construe. Reetz v. Bozanich, supra; City *439of Meridian v. Southern Bell Tel. & Tel. Co., 358 U. S. 639.

. In the present case the Wisconsin Act does not contain any provision whatsoever for notice and hearing. There is no ambiguity in' the state statute. There are no provisions which could fairly be taken to mean that notice and hearing might be given under some circumstances or under some construction but not under others. The Act on its face gives the chief of police the power to do what he did to the appellee. Hence the naked question, uncomplicated by an unresolved state law, is whether that Act on its face is unconstitutional. As we said in Zwickler v. Koota, 389 U. S. 241, 251, abstention should not be ordered merely to await an attempt to vindicate the claim in a state court. Where there is no ambiguity in thé state statute, the federal court should not abstain but should proceed to decide the federal constitutional claim, id., at 250-251. We would negate the history of the enlargement of the jurisdiction of the federal district courts,5 if we held the federal court should stay its hand and not decide the question before the state courts decided it.

Affirmed.

dissenting.'

The Court today strikes down, as unconstitutional, a Wisconsin statute that has never been challenged or tested in the Wisconsin state courts. The judges of Wisconsin probably will'be taken by surprise by our summary action since few, if any, have ever heard of this case.

*440Very likely we reach a correct result since the Wisconsin statute appears, on its face and in its application, to be in conflict with accepted concepts of due process.

The reason for my dissent is that it seems to me a very odd business to strike down a state .statute, on the books for almost 40 years, without any opportunity for the state courts to dispose of the problem either under the Wisconsin Constitution or the U. S. Constitution. For all we know, the state courts would find this statute invalid under the State Constitution,1 but no one on either side of the case thought to discuss this or exhibit any interest in the subject. Since no one could reasonably think that the judges of Wisconsin have less fidelity to due process requirements of the Federal Constitution than we do, this case is, for me, a classic illustration of one in which we should decline to act until resort to state courts has been exhausted. At oral argument counsel for Mrs. Constantineau was candid in saying that he had deliberately avoided resort to the state courts because he could secure, and indeed did secure, a three-judge federal district court to decide the issue and, in that posture, appeal would lie directly to this Court.

Only recently in the 1969 Term we held unanimously that a challenge, under the Equal Protection Clause of the Fourteenth Amendment and under certain provisions of the Alaska Constitution, to the constitutionality of a state statute restricting commercial salmon fishing licenses should not have been decided by the federal district court until the courts of Alaska haid acted. There, *441as here, the statute’s challenger wanted to use the “short cut” Congress has authorized. As here, the “short cut” was to convene a three-judge federal district court which held the Alaska statute invalid. Notwithstanding that the license applicants presented a sound claim, Mr. Justice Douglas, speaking for a unanimous Court, said:

“We are advised that the provisions of the Alaska Constitution at issue have never been interpreted by an Alaska court. The District Court, feeling sure of its grounds on the merits, held, however, that this was not a proper case for abstention, saying that 'if the question had been presented to an Alaska court, it would have shared our conviction that the challenged gear licensing scheme is not supportable.’ 297 F. Supp., at 304. The three-judge panel was' a distinguished one, two being former Alaska lawyers. And they felt that prompt decision was necessary to avoid the ‘grave and irreparable’ injury to the ‘economic livelihood’ of the appellees which would result, if they could not engage in their occupation ‘during this year’s forthcoming fishing season.’ Ibid.

“It is, of course, true that abstention is not necessary whenever a federal court is faced with a question of local law, the classic case being Meredith v. Winter Haven, 320 U. S. 228, where federal jurisdiction was based on diversity only. Abstention certainly involves duplication of. effort and expense and an attendant delay. See England v. Louisiana State Board, 375 U. S. 411. That is why we have said that this judicially created rule which stems from Railroad Comm’n v. Pullman Co., 312 U. S. 496, should be applied only where ‘the issue of state law is uncertain.’ Harman v. Forssenius, 380 U. S. 528, 534.” Reetz v. Bozanich, 397 U. S. 82, 86 (1970).

*442This very wise doctrine is an essential one of policy and is a keystone of federalism. Previously this Court had underscored this concept, saying:

“Proper exercise of federal jurisdiction requires that controversies involving unsettled questions of state law be decided in the state tribunals preliminary to a federal court’s consideration of the underlying federal constitutional questions. In such a case, when the state court’s interpretation of the statute or evaluation of its validity under the state constitution may obviate any need to consider its validity under the Federal Constitution, the federal court should hold its hand, lest it render a constitutional decision unnecessarily.” City of Meridian v. Southern Bell Tel. & Tel. Co., 358 U. S. 639, 640-641 (1959).

See also Fornaris v. Ridge Tool Co., ante, p. 41.

It is no answer to contend that there is no ambiguity in the Wisconsin statute and hence .no need to abstain; in Reetz the Alaska statute could not have been more plain, or less susceptible of a limiting construction. Yet, in furtherance of this Court’s firm policy to steer around head-on collisions with the States by avoiding unnecessary constitutional decisions, we reversed the District Court and remanded with instructions to stay its hand while the litigants exhausted state court remedies for resolution of their challenge to the statute. See also Fornaris v. Ridge Tool Co., supra. Reetz cannot be distinguished and I see no reason to depart from the principles it reaffirmed.2

*443I quite agree that there is no absolute duty to abstain— to stay our hand — until the state courts have at least been asked to construe their own statute, but for me it is the negation of sound judicial administration — and an unwarranted use of a limited judicial resource — to impose this kind of case on a three-judge federal district court, and then, by direct appeal, on this Court. Indeed, in my view, a three-judge district court would be well advised in cases such as this, involving no urgency or question of large import, to decline to act.

This Court has an abundance of important work to do, which, if it is to be done well, should not be subject to the added pressures of non-urgent state cases which the state courts have never been called on to resolve. Neither the historic role of this Court nor any reasonable duty placed on us, calls for our direct intervention when no reason for. expedited review is shown. Here we have an example of an unwise statute making direct review prima jade available, and an unwillingness by the Court to follow .its own precedents by declining to pass on the Wisconsin statute before Wisconsin courts do so. We should remand this case with directions to the three-judge court to refrain from acting until the Wisconsin courts have acted.

dissenting.

I agree substantially with the dissent of The Chief Justice. I would vacate the District Court’s judgment and remand with directions to withhold its proceedings to enable appellee to file a declaratory judgment or other state court action challenging the police chief’s posting of notices in all Hartford retail liquor outlets forbidding sales or gifts of liquors to appellee for one year. As the *444Court’s opinion, the cases there cited, and The Chief Justice’s dissent point out, such a course of action is justified “where the issue of state law is uncertain” and where the state court might confine the state law’s meaning so “as not to have' any constitutional infirmity.” The Wisconsin Act appears on its face to grant authority to a man’s wife, a mayor, a town’s supervisors, the county s? tendent of the poor, a sheriff, or a district attorney to post notices forbidding liquor establishments from giving or selling any alcoholic beverages to the person so posted. The effect of such sweeping powers, if there is nothing else in the State’s law to limit them, is practically the same as that of an old common-law bill of attainder, against which our forebears had such an abhorrence that they forbade it in Art. I, § 9, of the Constitution. See, e. g., United States v. Lovett, 328 U. S. 303 (1946). And here the Wisconsin law purports on its face to place such arbitrary -and tyrannical power, in the hands of minor officers and others that these modern bills of attainder can be issued ex parte, without notice or hearing of any kind or character. ' It is impossible for me to believe that the Supreme Court of Wisconsin would uphold any such boundless power over the lives and liberties of its citizens.. It seems to me therefore wholly uncertain that the state law has the meaning it purports to have, and I believe it is. unfair to Wisconsin to permit its courts to be denied the opportunity óf confining this law within its proper limits if it could bé shown that there are other state law. provisions that, could provide such boundaries. For example, notice and hearing might be provided by principles of state administrative procedure law similar to the federal Administrative Procedure Act.

I realize that there are many cases where, federal courts should not stay their hands to permit state courts to *445interpret state law. Compare Clay v. Sun Insurance Office, 363 U. S. 207, 213-227 (I960) (Black, J., dissenting), with Burford v. Sun Oil Co., 319 U. S. 315 (1943). Here, however, no state court appears to have passed ón this Act at all, and a state decision might well apply the body of other state law to require notice, hearing, and other necessary provisions to render the challenged Act constitutional.
