Appellant World Famous Drinking Emporium, Inc. ["World Famous"] appeals from the judgment of dismissal of its claim under 42 U.S.C. Sec. 1983, entered upon the basis of the abstention doctrine as enunciated in Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971). We have jurisdiction under 28 U.S.C. Sec. 1291. We affirm.

Pursuant to a municipal zoning ordinance1 World Famous sought an entertainment use permit from Tempe for a nightclub featuring live entertainment in the form of female "gо-go" and "flash" dancers.2

The Tempe Board of Adjustment ["the Board"] held its first hearing on World Famous' application in November 1983. The Board denied the application. Upon reconsideration in January 1984, the Board denied the aрplication a second time. World Famous then sought to overrule the Board by way of a "special action" proceeding in Maricopa County Superior Court.3 Judge Marquardt upheld the Board.

World Famous' continued operation led Tempe to filе criminal proceedings and a civil enforcement action. In the latter action, Tempe sought preliminary and permanent injunctive relief. World Famous opposed Tempe's request by arguing, inter alia, the unconstitutionality of the zoning ordinance. Judge LaPrade granted the preliminary injunction on September 27, 1984. World Famous complied with the terms of the injunction and ceased presenting go-go and flash dancing. Following denial by the Arizona Supreme Court of special action relief, Tempe dismissed the criminal proeeding. Judge LaPrade denied World Famous' motions to dissolve the injunction and to dismiss the case, and granted Tempe's motion for summary judgment.

World Famous again sought the requisite use permit without success, and filed another special action petition in Superior Court, which was dismissed by Judge Howe on August 16, 1985.

World Famous filed its Sec. 1983 action on July 17, 1985 in United States District Court for the District of Arizona. Based solely upon the abstention doctrine as enunciated in Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971), Judge Strand granted Tempe's motion to dismiss on September 8, 1985, stating in his memorandum:

The issue of the constitutionality of the Tempe zoning ordinance is presently before the trial court in this case and wоuld be subject to appellate review in the state court should an aggrieved party elect to take such action.

World Famous timely appealed.

The decision whether to abstain under Younger is reviewable do novo. Goldie's Bookstore, Inc. v. Superior Court of California, 739 F.2d 466, 468 (9th Cir.1984). See also Fresh International Corp. v. Agricultural Labor Relations Board, 805 F.2d 1353, 1356 (9th Cir.1986). 'When a case falls within the proscription of Younger, a district court must dismiss the federal action." Id. ‍​​‌‌‌​​​​‌​​​‌‌‌​​‌​‌​​​‌‌​‌‌‌​​‌‌​​‌‌​‌‌‌‌‌​​‌​‍ When a case involves abstention on some ground other than Younger, e.g., abstention under Railroad Commission v. Pullman Co., 312 U.S. 496, 61 S.Ct. 643, 85 L.Ed. 971 (1941), we have stated that the standard of review is one of abuse of discretion, with the discretion to "be exercised within the narrow and specific limits prescribed by the particular abstention doctrine involved." C-Y Development Co. v. City of Redlands, 703 F.2d 375, 377 (9th Cir.1983) (quoting Pue v. Sillas, 632 F.2d 74, 78 (9th Cir.1980)). See also Fresh International Corp. at 1356 n. 2. In the case at bench, the district court abstained on the basis of Younger. No other abstention principlе is involved. Our review, therefore, is de novo.

Abstention from the exercise of federal jurisdiction is the exception, not the rule. Colorado River Water Conservation District v. United States, 424 U.S. 800, 96 S.Ct. 1236, 47 L.Ed.2d 483 (1976). Absent significant countervailing interests, the federal сourts are obliged to exercise their jurisdiction. Id.; County of Allegheny v. Frank Mashuda Co., 360 U.S. 185, 189, 79 S.Ct. 1060, 1063, 3 L.Ed.2d 1163 (1959). In Younger v. Harris, the Supreme Court held that federal courts should not enjoin pending state criminal proceedings except under extraordinary circumstаnces where the danger of irreparable loss is both great and immediate. 401 U.S. at 46, 91 S.Ct. at 751. Id. Three requirements have evolved for proper invocation of Younger: (1) ongoing state judicial proceedings; (2) implication of an important state interest in the proceedings; and (3) an adequate opportunity to raise federal questions in the proceedings. Goldie's, 739 F.2d at 469 (citing Middlesex Ethics Committee v. Garden State Bar Association, 457 U.S. 423, 432, 102 S.Ct. 2515, 2521, 73 L.Ed.2d 116 (1981)). Bad faith prosecution or harassment make abstention inappropriate even where these requirements are met. Younger, 401 U.S. at 47-49, 91 S.Ct. at 752-53. Similarly, satisfaction of the three requirements will not support abstention where a statute is flagrantly and patently violative of constitutiоnal prohibitions. Id. at 53-54, 91 S.Ct. at 755-56.

At the time the district court abstained, World Famous had yet to appeal the adverse judgments in World Famous II and World Famous III to the state Supreme Court. Failure to exhaust state appellate remedies satisfies the requirement that there be "ongoing judicial proceedings" in order to justify federal abstention. See Huffman v. Pursue, Ltd., 420 U.S. 592, 608-09, 95 S.Ct. 1200, 1210, 43 L.Ed.2d 482 (1975). A First Amendment challenge does not alter the propriety of abstention in such a case. See Ohio Civil Rights Commission v. Dayton Christiаn Schools, Inc., --- U.S. ----, 106 S.Ct. 2718, 2724, 91 L.Ed.2d 512 (1986) (abstention proper where a First Amendment challenge may be raised in state court review of an administrative proceeding); Huffman, 420 U.S. at 612-13, 95 S.Ct. at 1212, 43 L.Ed.2d 482 (1975).

2. Important State Interest Implicated in State Proceedings

Younger abstention is not limited to ongoing state criminal proceedings, see, e.g., Huffman, 420 U.S. at 609, 95 S.Ct. at 1210. It extends to certain civil proceedings provided those proceedings implicate important state interests. ‍​​‌‌‌​​​​‌​​​‌‌‌​​‌​‌​​​‌‌​‌‌‌​​‌‌​​‌‌​‌‌‌‌‌​​‌​‍ See Ohio Civil Rights Commission v. Dayton Christian Schools, Inc., ---- U.S. ----, 106 S.Ct. 2718, 2724, 91 L.Ed.2d 512 (1986) (state civil rights enforcement proceedings); Moore v. Sims, 442 U.S. 415, 99 S.Ct. 2371, 60 L.Ed.2d 994 (1979) (temporary removal of child in child-abuse context); Trainor v. Hernandez, 431 U.S. 434, 97 S.Ct. 1911, 52 L.Ed.2d 486 (1977) (proceeding for recovery of fraudulently obtained welfare benefits); Middlesex, 423 U.S. at 432, 102 S.Ct. at 2521 (state bar discipline proceedings); Huffman, 420 U.S. at 605, 95 S.Ct. at 1208 (state nuisance proceeding akin to criminal prosecution). In evaluating whether the proceedings implicate important state interests, we examine the nature of the proceedings. The fact that the noncriminal proceedings closely relate to criminal proceedings, seе Huffman, 420 U.S. at 604, 95 S.Ct. at 1208, or vindicate important state policies, see Trainor, 431 U.S. at 445, 97 S.Ct. at 1919, or are necessary for the functioning of the state judicial system, see Juidice v. Vail, 430 U.S. 327, 336, 97 S.Ct. 1211, 1217, 51 L.Ed.2d 376 (1977), demonstrates an important state interest. See Middlesex, 457 U.S. at 431, 102 S.Ct. at 2520. In each of these cases, the state was a party to the proceеdings. See Miofsky v. Superior Court, 703 F.2d 332, 337 (9th Cir.1983). See also Worldwide Church of God, Inc. v. California, 623 F.2d 613, 616 (9th Cir.1980) (state receivership order pursuant to investigation and regulation of fraud in charitable trusts), cert. denied, 449 U.S. 900, 101 S.Ct. 270, 66 L.Ed.2d 130 (1980); Rosenthal v. Carr, 614 F.2d 1219, 1220 (9th Cir.) (state bar disciplinary proceedings), cert. denied 447 U.S. 927, 100 S.Ct. 3024, 65 L.Ed.2d 1121 (1980).

Here, Tempe brought a civil action in order to obtain compliance with an ordinance which aims at avoidance of public nuisances. It had the option of proceeding either by civil or criminal enforcеment of its municipal ordinance; the option of criminal enforcement demonstrates the importance of the underlying state interest. See Trainor, 431 U.S. at 449-50, 97 S.Ct. at 1920-21 (Blackmun, J., concurring). Such an action, in aid of and closely related to Tеmpe's zoning ordinance and akin to a criminal prosecution, clearly involves an important state interest. See Middlesex, 457 U.S. at 434, 102 S.Ct. at 2522 (state bar disciplinary action); Trainor, 431 U.S. at 444, 97 S.Ct. at 1918 (civil proceeding brought to recover fraudulently obtained welfare payments); Huffman, 420 U.S. at 604, 95 S.Ct. at 1208 (public nuisanсe action). Cf. Playtime ‍​​‌‌‌​​​​‌​​​‌‌‌​​‌​‌​​​‌‌​‌‌‌​​‌‌​​‌‌​‌‌‌‌‌​​‌​‍Theatres, Inc. v. City of Renton, 748 F.2d 527, 532-33 (9th Cir.1984) (city's suit for declaratory relief not similar to criminal or "quasi-criminal" proceedings, nor did it involve interests vital to operation of state government), rev'd on other grounds, 475 U.S. 41, 106 S.Ct. 925, 89 L.Ed.2d 29 (1986); Goldie's, 739 F.2d at 469 (private unlawful detainer action does not implicate state interests); Miofsky v. Superior Court, 703 F.2d 332, 338 (9th Cir.1983) (private tort litigation does not implicate state interests). As such, the second requirement for the proper invocation of Younger abstention is satisfied.

3. Adequate Opportunity to Raise Federal Question

World Famous has failed to demonstrate how review of the adverse judgments in the state courts would not have permitted an opportunity to litigate its constitutional claims. That World Famous failed to avail itself of the opрortunity to litigate its constitutional claim in the state forum, does not demonstrate that the state forum did not provide an opportunity to litigate that claim. See Juidice v. Vail, 430 U.S. 327, 337, 97 S.Ct. 1211, 1218, 51 L.Ed.2d 376 (1977). World Famous had an opportunity to pursue its constitutional сlaim upon appeal in the state courts,4 and failed to do so. No more is required for Younger abstention. See Ohio Civil Rights Commission, 106 S.Ct. at 2724; Moore, 442 U.S. at 426, 99 S.Ct. at 2379; Juidice, 430 U.S. at 337, 97 S.Ct. at 1218.

Further, the record reveals no harassment or bad faith on the part of Tempe in bringing the civil enforcement and criminal proceedings which would make abstention improper. See Huffman, 420 U.S. at 611, 95 S.Ct., at 1211.

We hold abstention was proper and the merits of the constitutionality issue are not properly before this Court. See Singleton v. Wulff, 428 U.S. 106, 121, 96 S.Ct. 2868, 2877, 49 L.Ed.2d 826 (1976). See also Huffman, 420 U.S. at 602, 95 S.Ct. at 1207 (facial invalidity of statute is not exceptional circumstance justifying federal interference with state criminal proceedings) (citing Younger, 401 U.S. at 53-54, 91 S.Ct. at 754-55).

We also decline to consider World Famous' estoppel argument. World Famous fails to providе us with a reason for its failure to raise the estoppel issue below. Nor is the estoppel determination one of law whose proper resolution is beyond any doubt, see Telco Leasing, Inc. v. Transwestern Title Co., 630 F.2d 691, 693 (9th Cir.1980). Accоrdingly, the estoppel issue is not properly before us. See Kline v. Johns-Manville, 745 F.2d 1217, 1221 (9th Cir.1984); Taylor v. Sentry Life Insurance Co., 729 F.2d 652, 665-56 (9th Cir.1984).

Affirmance makes unnecessary the consideration of Tempe's assertion that World Famous' action is precluded by the adverse determinations below.

AFFIRMED.

General principles of abstention are distinct from the doctrine of ‍​​‌‌‌​​​​‌​​​‌‌‌​​‌​‌​​​‌‌​‌‌‌​​‌‌​​‌‌​‌‌‌‌‌​​‌​‍dismissal for lack of jurisdiction pursuant to Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971), and Huffman v. Pursue, Ltd., 420 U.S. 592, 95 S.Ct. 1200 (1975). Only the latter rule is applicable here, and Huffman squarely controls. I cоncur in the judgment.
