Miner Electric, Inc., and Russell E. Miner (“Miner parties”) filed a complaint in federal district court against Muscogee (Creek) Nation (“Nation”), a federally-recognized Indian tribe. In their complaint, the Miner parties sought declaratory and injunctive relief related to a forfeiture order entered by the Nation’s District Court (“Tribal Court”). The Nation moved to dismiss the complaint based upon its sovereign immunity. The district court denied the motion to dismiss and subsequently granted summary judgment in favor of the Miner parties. On appeal, the Nation argues that the district court erred in denying its motion to dismiss and in granting summary judgment. Exercising jurisdiction pursuant to 28 U.S.C. § 1291, we hold that the Nation has not waived, nor has Congress abrogated, its sovereign immunity. We therefore REVERSE and REMAND, with instructions to the district court to VACATE its judgment in favor of the Miner parties and to enter a judgment of DISMISSAL.
1. Background
The relevant historical and procedural facts are undisputed. The Nation operates a casino on “Indian country” land, as defined by 18 U.S.C. § 1151. Mr. Miner parked a vehicle owned by Miner Electric in the casino parking lot on June 15, 2004, where it remained until the following day. On June 16, tribal security officers seized the vehicle, as well as suspected illegal drugs and approximately $1,400 in cash found inside of the vehicle. The officers issued Mr. Miner a civil citation for Disorderly Conduct: Possession of Controlled Dangerous Substance. He entered a guilty plea to the civil citation in the Tribal Court on June 30, 2004, and was assessed and paid a civil fine and court costs. That same day, the Nation served Mr. Miner with notice of a civil forfeiture proceeding in the Tribal Court, seeking to forfeit to the Nation the vehicle and cash seized on June 16, pursuant to tribal law. Miner Electric intervened in the forfeiture proceeding, asserting ownership of the vehicle. After a hearing in which the Miner parties participated, the Tribal Court entered an order on January 10, 2005, forfeiting the property to the Nation. The Tribal Court’s order was upheld on appeal *1009 by the Nation’s Supreme Court on April 29, 2005.
The Miner parties filed this action in district court on June 23, 2005. In their complaint they sought relief from the forfeiture order on the basis that the Tribal Court lacked jurisdiction over a quasi-criminal proceeding against non-Indians. 1 They contended that the forfeiture was a denial of their rights under the Fifth and Eighth Amendments and Title I of the Indian Civil Rights Act (“ICRA”), 25 U.S.C. §§ 1301-03. They also argued that the forfeiture was not authorized by tribal statute. The Miner parties sought declaratory and injunctive relief, including an injunction against execution of the forfeiture order; a declaration that the Tribal Court did not have jurisdiction over them for purposes of the forfeiture proceeding; and a return of the seized property to them. In their complaint, the Miner parties asserted that they had exhausted all tribal remedies and that the ICRA operated as a waiver of tribal immunity.
The Nation moved to dismiss the complaint under Fed.R.Civ.P. 12(b)(1), arguing that it was not subject to suit based upon its sovereign immunity. The district court denied the motion, reasoning that because it had authority to determine whether the Tribal Court exceeded its jurisdiction in the forfeiture proceeding, it therefore also had jurisdiction over the Nation. The district court then granted summary judgment in favor of the Miner parties. The Nation filed a timely appeal.
II. Discussion
“Tribal sovereign immunity is a matter of subject matter jurisdiction, which may be challenged by a motion to dismiss under Fed.R.Civ.P. 12(b)(1).”
E.F.W. v. St. Stephen’s Indian High Sch.,
A. Tribal Sovereign Immunity
The Nation argues that dismissal was required under
Santa Clara Pueblo v. Martinez,
In
Kiowa Tribe of Oklahoma v. Manufacturing Technologies, Inc.,
This court has applied the Supreme Court’s straightforward test to uphold Indian tribes’ immunity from suit. In
Burrell v. Armijo,
The Nation contends on appeal, as it did in the district court, that its immunity from suit has not been abrogated by Congress, nor has the Nation unequivocally waived it.
See, E.F.W.,
B. Federal-Question Jurisdiction
The Miner parties argue that the district court properly denied the Nation’s motion to dismiss because the court had jurisdiction to decide the federal question regarding the scope of the Tribal Court’s jurisdiction. They assert that “[rjesolving the question of federal question jurisdiction necessarily involves delineating the reach of tribal sovereign immunity.” Aplee. Br. at 6. The Nation counters that the district court erred in equating subject-matter ju *1011 risdiction based upon a federal question under 28 U.S.C. § 1331 with subject-matter jurisdiction over the Nation. Although the district court acknowledged the Nation’s contentions that its sovereign immunity had not been abrogated or waived, it did not grant the motion to dismiss on that basis. Instead, after reviewing cases defining the scope of tribal court jurisdiction and the origin and nature of civil forfeiture proceedings, the district court denied the motion, holding that
[a] federal district court has the authority to determine whether a tribal court had the power to exercise civil subject matter jurisdiction over a non-Indian’s property rights. Accordingly, the Court finds that it has jurisdiction over the Creek Nation, and the subject matter of this action, and the power to issue injunctive relief as requested in this proceeding.
Aplt.App. at 48 (citation omitted).
We disagree that federal-question jurisdiction negates an Indian tribe’s immunity from suit. Indeed, nothing in § 1331 unequivocally abrogates tribal sovereign immunity. In the context of the United States’ sovereign immunity, we have held that
[w]hile 28 U.S.C. § 1331 grants the court jurisdiction over all civil actions arising under the Constitution, laws or treaties of the United States, it does not independently waive the Government’s sovereign immunity; § 1331 will only confer subject matter jurisdiction where some other statute provides such a waiver.
High Country Citizens Alliance v. Clarke,
C. Tenneco
The Miner parties argue that the district court properly relied on
Tenneco,
When the complaint alleges that the named officer defendants have acted outside the amount of authority that the sovereign is capable of bestowing, an exception to the doctrine of sovereign immunity is invoked. If the sovereign did not have the power to make a law, then the official by necessity acted outside the scope of his authority in enforcing it, making him liable to suit. Any other rule would mean that a claim of sovereign immunity would protect a sov *1012 ereign in the exercise of power it does not possess.
Id.
(citation omitted). Thus, we concluded that the tribal officer defendants were not protected by the tribe’s immunity and that the suit could go forward
against them. Id.
at 575. We noted that our holding was consistent with
Santa Clara. Pueblo,
where the Supreme Court held that a tribal officer was not protected by the tribe’s immunity from suit.
See Tenneco,
Like this case, Tenneco involved two different aspects of an Indian tribe’s “sovereignty”: its immunity from suit and the extent of its power to enact and enforce laws affecting non-Indians. But it does not stand for the proposition, as the Miner parties suggest, that an Indian tribe cannot invoke its sovereign immunity from suit in an action that challenges the limits of the tribe’s authority over non-Indians. On the contrary, we held in Tenneco that the tribe was immune from suit. See id. at 574. Here, because the Miner parties named only the Nation itself as a defendant, we do not reach the question whether any of the Nation’s officials would be subject to suit in an action raising the same claims.
I). Dry Creek Exception
The Miner parties’ final argument against the Nation’s immunity from suit relies on this court’s decision in
Dry Creek,
The Miner parties clearly fail to come within the narrow
Dry Creek
exception to tribal sovereign immunity. Considering whether they could have brought this action in the Tribal Court rather than the district court, they hypothesize that the Nation would have claimed immunity from suit in that forum as well. But they must show an actual attempt; their assumption of futility of the tribal-court remedy is not enough. Moreover, “[a] tribal court’s dismissal of a suit as barred by sovereign immunity is simply not the same thing as having no tribal forum to hear the dispute.”

III. Conclusion
We conclude that, in the absence of congressional abrogation of tribal sovereign immunity from suit in this action, or an express waiver of its sovereign immunity by the Nation, the district court erred in failing to grant the Nation’s motion to dismiss. The judgment of the district court is REVERSED and this case is REMANDED, with instructions to the district court to VACATE the judgment in favor of Miner Electric, Inc., and Russell E. Miner and to enter a judgment of DISMISSAL.
