Stephen Paul Dunifer ("Dunifer") appeals from the district court's summary judgment granting injunctive and declaratory relief in favor of the United States in this action brought under S 301 of the Communications Act of 1934, 47 U.S.C. S 301, which prohibits the operation of a radio station without a Federal Communications Commission ("FCC") license.1 Dunifer contends that the district court erred in ruling that he lacked standing to challenge the statutory validity and constitutionality of FCC licensing regulations as a defense to the government's action. The district court had jurisdiction of the underlying action pursuant to 28 U.S.C. SS 1331 and 1345, and 47 U.S.C. S 401(a). We have jurisdiction under 28 U.S.C. S 1291. We do not reach the standing issue because we conclude that the district court lacked subject matter jurisdiction under the applicable statutory framework to decide Dunifer's challenges to the licensing regulations, and we affirm on that ground.

In late April and early May 1993, agents from the FCC's Field Operations Bureau ("Bureau") monitored transmissions on an FM frequency from an unlicensed, low power radio station in Berkeley, California, which identified itself as "Free Radio Berkeley." The strength of the signals was determined to be greater than that permitted for unlicensed stations under 47 C.F.R. S 15.239(b).2 The agents traced the transmissions to an antenna on the roof of Dunifer's residence and, in June 1993, the Bureau sent Dunifer a Notice of Apparent Liability for a monetary forfeiture of $20,000.

Dunifer filed a response to the notice asserting constitutional, statutory, and evidentiary arguments why a forfeiture should not be imposed, all of which the Bureau rejected. In December 1993, Dunifer filed an Application for Review of the forfeiture with the FCC.

In October 1994, before the FCC responded to the Application for Review, the government, on behalf of the FCC, brought this action for declaratory and injunctive relief to prohibit Dunifer from engaging in unlicensed radio broadcasting in violation of S 301.

In its initial order, the district court denied the government's motion for a preliminary injunction. It found that, while the government had shown probable success on the merits that Dunifer violated S 301 by broadcasting without a license, it did not show a sufficient probability of success in rebutting Dunifer's contention that FCC regulations precluding low power radio broadcasting were unconstitutional3.The district court also found that there was no possibility of irreparable harm, in part because the government could not support its assertions that Free Radio Berkeley was interfering with licensed broadcasts. The district court then stayed the action under the doctrine of primary jurisdiction, so that the FCC could first address in administrative proceedings the constitutional arguments raised by Dunifer. In August 1995, the FCC rejected Dunifer's constitutional arguments by responding to his Application for Review of the initial forfeiture order, and it ultimately imposed a $10,000 monetary forfeiture.

The government then moved for summary judgment. The district court held that it had subject matter jurisdiction under the applicable statutory scheme to hear Dunifer's arguments concerning the unconstitutionality of the regulations, assuming that Dunifer had standing to raise those arguments. Nonetheless, the district court requested the parties to brief further whether "the unconstitutionality of the FCC regulatory scheme would be a valid defense" to the statutory violation in the first instance.

In its final order, the district court granted summary judgment in favor of the government and permanently enjoined Dunifer from broadcasting without a license. It held that Dunifer lacked standing to challenge the regulations, except for overbreadth under the First Amendment. It then rejected Dunifer's overbreadth challenge on the merits. Dunifer filed a motion to amend the judgment, see Fed. R. Civ. P. 59(a), which was denied. Dunifer timely appealed.

We review de novo the district court's assumption of jurisdiction. See United States v. Bennett, 147 F.3d 912, 913 (9th Cir. 1998). We may affirm the district court's judgment on any ground supported by the record. See Granite State Ins. Co. v. Smart Modular Techs., Inc., 76 F.3d 1023, 1026 (9th Cir. 1996).

Because we conclude that the Communications Act precludes the district court's jurisdiction to decide Dunifer's defenses in this case, we need not examine whether the district court lacked jurisdiction over Dunifer's defenses on the ground of lack of standing. Pursuant to 47 U.S.C.S 401(a), the district courts have jurisdiction to entertain actions by the government to enjoin persons who are broadcasting in violation of the statutory licensing requirement. Even though Dunifer does not challenge the constitutionality of the statutory licensing requirement of S 301,4 he asserts that his challenge to the regulations implementing that provision is a valid defense to the requested injunction. Ordinarily, the district courts would have subject matter jurisdiction to entertain constitutional and statutory defenses to an injunctive action. See, e.g., United States v. Hugs, 109 F.3d 1375, 1377-78 (9th Cir. 1997) (holding implicitly that the district court had jurisdiction to entertain the defendants' challenge to the facial constitutional validity of a regulatory licensing scheme).

However, 47 U.S.C. S 402(a) provides that "[a]ny proceeding to enjoin, set aside,annul, or suspend any order of the Commission under this chapter (except those appealable under subsection (b) of this section)[5]shall be brought as provided by and in the manner prescribed in chapter 158 of title 28." In turn, 28 U.S.C. S 2342 (in chapter 158) provides that "[t]he court of appeals . . . has exclusive jurisdiction to enjoin, set aside, suspend . . . or determine the validity of -(1) all final orders of the [FCC] made reviewable by section 402(a) of title 47."

In Sable Communications of Cal., Inc. v. FCC, 827 F.2d 640 (9th Cir. 1987), we held that the district court lacked jurisdiction over an action claiming that a FCC regulation unconstitutionally restricted sexually suggestive telephone services, because the challenge to the regulation was effectively an action to " `enjoin, set aside, suspend [and] determine the validity of' " a final order of the FCC. Id. at 642-43 (quoting 28 U.S.C. S 2342); see also Wilson v. A.H. Belo Corp., 87 F.3d 393, 396-97 (9th Cir. 1996) ("Together, [SS 402(a) and 2342] vest the courts of appeals with exclusive jurisdiction to review the validity of FCC rulings."); Moser v. FCC, 46 F.3d 970, 973 (9th Cir. 1995) (noting that a challenge to FCC regulations is outside the jurisdiction of the district court).

By its terms, the Communications Act's jurisdictional limitations apply as much as to affirmative defenses as to offensive claims. We find especially persuasive the Eighth Circuit's opinion in United States v. Any and All Radio Transmission Equip., 207 F.3d 458 (8th Cir. 2000) ("Laurel Avenue"), in which the court so held6.

As the Eighth Circuit properly noted, the Supreme Court has already determined that "the exclusive jurisdiction of the Court of Appeals over rulemaking by the FCC may not be evaded by seeking to enjoin a final order of the FCC in the district court." Id. at 463 (citing FCC v. ITT World Communications, Inc. , 466 U.S. 463, 468 (1984)). To allow Dunifer to contest the validity of the implementing regulations would create just such an evasion. See Laurel Avenue, 207 F.3d at 463 ("A defensive attack on the FCC regulations is as much an evasion of the exclusive jurisdiction of the Court of Appeals as is a preemptive strike by seeking an injunction.").

Dunifer relies on the recent opinion of the Sixth Circuit in United States v. Any and All Radio Station Transmission Equip., 204 F.3d 658 (6th Cir. 2000) ("Maquina Musical"), for the proposition that challenging the FCC regulations does not contest any "FCC order." Id. at 667. We have squarely held, however, that challenging FCC regulations is equivalent to an action to enjoin, annul, or set aside an order of the FCC. See Sable Communications, 827 F.2d at 642. Moreover, as we have expressed above, we agree with the reasoning of Laurel Avenue7.

In concluding that it otherwise had subject matter jurisdiction over Dunifer's defenses, aside from the standing issue, the district court relied on Dougan v. FCC, 21 F.3d 1488 (9th Cir. 1994). In that case, the petitioner sought review in this court of a final monetary forfeiture order of the FCCholding that he had violated S 301 and 17 C.F.R. S 15.29 "by operating a radio station without a license and by refusing to permit FCC engineers to inspect [Dougan's] station. " Id. at 1489. In particular, Dougan challenged the FCC's jurisdiction over his broadcasts as well as the constitutionality of the FCC licensing regulations. See id. at 1489-90. We held that this court lacked subject matter jurisdiction over the appeal, see id. at 1490-91, because the "specific" jurisdictional grant of S 504(a) to the district courts over forfeiture actions trumped the general jurisdictional grant of S 402(a) to the courts of appeals to review FCC orders, see id. We reasoned that "Congress did not intend to give petitioners two bites at the apple by allowing them to challenge the forfeiture in the appellate court and, if they lost, to sit back and await an enforcement action, at which time they would be entitled to a trial de novo in the district court." Id. at 1491 (citing Pleasant Broad. Co. v. FCC, 564 F.2d 496, 500-01 (D.C. Cir. 1977)).

We do not believe that Dougan's reasoning, with respect to challenges to FCC regulations, applies to injunctive actions. Specifically, the "two bites at the apple" reasoning does not apply to defensive constitutional challenges to the regulations if, under S 402(a), the district courts have no jurisdiction over them.8 We therefore decline the invitation to extend Dougan to injunctive actions; its holding remains limited to forfeiture actions brought under 47 U.S.C. S 504(a).

We conclude that the Communications Act's jurisdictional restrictions on the district courts require that anyone seeking to broadcast first go through the FCC, or be subjected to injunctive relief, even if the underlying regulatory (as distinct from statutory) scheme is claimed to be unconstitutional. As the Eighth Circuit properly noted, these statutory restrictions on jurisdiction are sensible. See Laurel Avenue, 207 F.3d at 463. First, by requiring the FCC initially to pass on the validity of its own regulations, the agency may apply its expertise to the question at hand. See id. Second, it "ensure[s] review based on an administrative record made before the agency charged with implementation of the statute. " Id. Third, it assists in "uniform, nationwide interpretation of the federal statute by the centralized expert agency created by Congress" to enforce the statutory scheme governing the nation's airwaves. New York Tel. Co. v. New York Dep't of Labor, 440 U.S. 519, 528 (1979).

In this regard, it is important to note that this is not a case in which Dunifer had no means to obtain judicial review of the regulations. Cf. Thunder Basin Coal Co. v. Reich, 510 U.S. 200, 212-13 (1994) (construing claims in a manner so as not to foreclose all judicial review). Dunifer could have applied for a license and sought a waiver of the applicable FCC rules,9 or he couldhave filed a petition for a rulemaking for new low power regulations,10 a denial of which would be reviewable by a court of appeals. See Turro v. FCC, 859 F.2d 1498, 1499 (D.C. Cir. 1988) (reviewing a denial of a license request pursuant to 47 U.S.C. S 402(b)); Quincy Cable TV, Inc. v. FCC, 768 F.2d 1434 (D.C. Cir. 1985) (reviewing a determination of the FCC regarding a petition for a rulemaking pursuant to 47 U.S.C. S 402(a)). Instead, Dunifer decided to evade this carefully crafted process by concededly violating the regulatory framework implemented by the FCC.

While the district court had jurisdiction to entertain the government's action for injunctive relief, it lacked jursidiction to adjudicate Dunifer's affirmative defenses. We therefore AFFIRM the decision of the district court, albeit on a different ground.
