The Worldwide Church of God appeals from the district court’s orders denying the Church a preliminary injunction and denying it leave to amend its civil rights complaint. The district court properly denied injunctive relief on the record before it, but the refusal to allow amendment of the Church’s complaint requires a remand.

On January 2, 1979, the Attorney General of the State of California, pursuant to his supervisory authority over charitable trusts under California Corporations Code § 9505,^[1] filed an action in state court, seeking an accounting of the finances of the Church and affiliated corporations and requesting that those entities be placed in receivership. The state’s complaint alleged that these actions were necessary to prevent diversion of Church assets from charitable purposes to the personal benefit of persons who controlled the Church. The state court, following an ex parte proceeding, appointed a temporary receiver. Several days later, af[*615]ter an adversary hearing, the court imposed a permanent receivership. The Church has continually, though unsuccessfully, challenged discovery orders relating to the accounting action in state court.^[2]

On January 16, 1979, the Worldwide Church filed an action under 42 U.S.C. § 1983 against California and individual state attorneys general in federal district court. The Church sought a preliminary injunction restraining the enforcement of the state receivership order during the pendency of the federal litigation, a permanent injunction against enforcement of the receivership, and damages for violations of its civil rights.

On February 22, the district court, relying on the abstention principles articulated in Younger v. Harris, 401 U.S. 37, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971), denied preliminary injunctive relief and granted the state’s motion to “dismiss the matter.” The Church then filed a motion under Fed.R. Civ.P. 59(e), requesting the court to modify its memorandum and order to permit the Church to amend its complaint. The district court denied that motion in a memorandum and order dated October 12, 1979, stating that any amendment would be “futile.” This appeal followed.^[3]

The Church initially contends that the district court’s finding that Younger abstention precluded preliminary injunctive relief was error and that injunctive relief should have been granted under the standards defined in Miss Universe, Inc. v. Flesher, 605 F.2d 1130, 1134 (9th Cir. 1979). Reliance on Younger, it is alleged, was inappropriate for either of two reasons. First, Younger did not apply because the enforcement of the receivership order which the Church sought to restrain is not a “pending state proceeding” nor does it implicate “important state interests.” See Moore v. Sims, 442 U.S. 415, 423, 99 S.Ct. 2371, 2377, 60 L.Ed.2d 994 (1979); Trainor v. Hernandez, 431 U.S. 434, 444, 97 S.Ct. 1911, 1918, 52 L.Ed.2d 486 (1977). Second, even if Younger could apply in this context, the state action either was based on a patently unconstitutional statute or was brought in bad faith, thereby bringing the case within recognized exceptions to the abstention doctrine. See Huffman v. Pursue, Ltd., 420 U.S. 592, 611, 95 S.Ct. 1200, 1211, 43 L.Ed.2d 482 (1975). The Church also argues that if abstention was proper, the district court erred in denying the Church the opportunity to amend its complaint to plead matters triggering either or both of the exceptions to Younger.

On the record then before it, the district court correctly invoked Younger abstention. Imposition of the receivership was an integral element of the ongoing state litigation. Enjoining enforcement of the receivership order would violate the principles of federalism, equity, and comity that Younger and related cases seek to preserve. See Huffman v. Pursue, Ltd., 420 U.S. at 601-604, 95 S.Ct. at 1206-1208; Younger v. Harris, 401 U.S. at 44, 91 S.Ct. at 750. The Church must exhaust its state appellate remedies in challenging the re[*616]ceivership before seeking relief in a federal court. Huffman, supra, 420 U.S. at 608-609, 95 S.Ct. at 1210-1211.

Investigation and regulation of fraud in charitable trusts, the state interest arguably implicated here, is an interest of the magnitude of controlling welfare fraud, Trainor v. Hernandez, supra, or regulating child custody, Moore v. Sims, supra.4 The Church contends that supervision of a religious institution’s internal finances is unconstitutional and, consequently, cannot be an “important state interest.” This type of argument, however, could be made in any federal litigation in which a plaintiff seeks to enjoin allegedly unconstitutional state proceedings, and, if accepted, would render Younger a nullity.

We are also unpersuaded that either of the exceptions to Younger abstention applies in this case. Even if the application of California Corporations Code § 9505 ^[5] to the Worldwide Church were unconstitutional, and we express no opinion on that question, the statute is not “flagrantly and patently violative of express constitutional prohibitions in every clause, sentence and paragraph, and in whatever manner and against whomever an effort might be made to apply it.” Younger v. Harris, 401 U.S. at 53-54, 91 S.Ct. at 755 (quoting Watson v. Buck, 313 U.S. 387, 402, 61 S.Ct. 962, 967, 85 L.Ed. 1416 (1941)). It is unquestioned that the state attorney general may constitutionally investigate and supervise the affairs of some charitable corporations.

Nor do the Church’s pleadings, in their present form, allege harassment or bad faith with sufficient specificity to trigger the second Younger exception. However, if the Church is permitted to amend its complaint, it might be able to allege facts demonstrating that the state action was brought in bad faith. Under Fed.R. Civ.P. 15(a), a party may, as a matter of right, amend its complaint once before the filing of a “responsive pleading” or the entry of final judgment following dismissal of its action. See Wright and Miller, Federal Practice and Procedure: Civil § 1483 (1971). Accord Breier v. Northern California Bowling Proprietors’ Ass’n, 316 F.2d 787, 789 n. 1 (9th Cir. 1963) (dictum). The state’s motion to dismiss was not a “responsive pleading” within the meaning of Rule 15(a), and the district court did not enter a final judgment dismissing the action. Accordingly, the Church retains its right of amendment under Rule 15. The district court erred in refusing to permit amendment of the complaint.

We affirm the denial .of the Church’s motion for a preliminary injunction and remand to allow amendment of the complaint.
