The plaintiff State of Oklahoma appeals from the denial of its motion to remand this case back to state court. The State asserts that removal of the case both violated the Eleventh Amendment and rested on an erroneous assertion of federal question jurisdiction. As explained below, we take jurisdiction of this interlocutory appeal under a particular variant of the collateral order doctrine, and, on the merits, hold that (1) the State’s Eleventh Amendment immunity did not bar removal, but (2) the specific basis for federal question jurisdiction relied on by the district court was insufficient to support removal. Accordingly, we remand the case for further consideration of several alternative bases for federal question jurisdiction invoked in defendants’ petition for removal. 1
A brief recitation of the immediately pertinent facts should suffice to put the legal questions in context. The State filed this tort action in the District Court of Muskogee County, Oklahoma, to recover damages it incurred when a tugboat pushing two barges on the Arkansas River collided with the Interstate 40 bridge near Webber Falls, Oklahoma. The collision caused a portion of the bridge to collapse, resulting in death or serious injury to numerous people as well as substantial property damage. The tugboat was owned and operated by defendant Magnolia Marine Transport Company, a wholly owned subsidiary of defendant Ergon, Inc., and was under the command of defendant William Joe Dedmon at the time of the accident.
Shortly after the state action was commenced, defendants filed a notice of removal in the United States District Court for the Eastern District of Oklahoma, broadly alleging several bases for federal jurisdiction in support of removal under 28 U.S.C. § 1441(a) and (b). See ApltApp. at 14-15. The State promptly moved to remand the case back to Muskogee County district court on the ground that removal subjected it to an involuntary assertion of federal court process and thereby violated its immunity under the Eleventh Amendment. See id. at 33-38. Defendants responded by arguing that the Eleventh Amendment applies to suits brought against the States, not to suits brought by a State. See id. at 39-44. In its subsequent reply, the State reargued the Eleventh Amendment point and, in the course of that argument, also asserted in passing that its tort complaint had not raised a federal question. See id. at 46.
The district court agreed with defendants’ view regarding the scope of the Eleventh Amendment and denied the State’s motion for remand. See id. at 51-57. The district court also discussed the relatively unexplored question of federal subject matter jurisdiction supporting removal, holding that the State’s action for damages caused by a commercial vessel on navigable waters was a “civil case of admiralty or maritime jurisdiction” and thus within its original jurisdiction under 28 *1239 U.S.C. § 1333(1). Id. at 55-57. The State now appeals, challenging both of these holdings.
Ordinarily, an interlocutory appeal may not be taken from the denial of a motion to remand a previously removed case.
See Caterpillar Inc. v. Lewis,
We review the district court’s determination of the Eleventh Amendment question de novo.
Chaffin v. Kan. State Fair Bd.,
More specifically regarding removal, the Supreme Court has held without qualification that “where a State is suing parties who are not other States,” the suit may “ ‘be brought in
or removed to’
” the federal district courts “ ‘without regard to the character of the parties.’ ”
Illinois v. City of Milwaukee,
Thus, although we appear to be the first circuit court to examine the precise issue, our course here is hardly uncharted. Consistent with the constitutional text, relevant pronouncements of the Supreme Court, and the vast majority of district court cases directly on point, we hold that the State may not assert its Eleventh Amendment immunity to preclude defendants’ removal of the tort action it brought against them in its own courts.
We hasten to add that our decision is not as broad as it may appear. There is an important factual qualification on our holding, not touched on in the body of case law cited above, that limits its direct effect on the question of removal per se as well as its significance for potential Eleventh Amendment issues that may arise post-removal. This appeal presents a simplest-case scenario for Eleventh Amendment analysis, in that the removed action involved only claims asserted by the State and no party sought to interject counterclaims or cross-claims against the State upon removal. Thus, we need not and do not express any opinion as to whether a private defendant may remove an action that includes claims of this sort asserted against a State plaintiff. 2 Nor does our decision imply or suggest any particular result in the event a party seeks to assert a counterclaim or cross-claim against the State after removal over the State’s objection. 3
Turning to the jurisdictional basis for removal, the district court held that removal was proper based on 28 U.S.C. § 1333(1), which grants federal district courts “original jurisdiction, exclusive of the courts of the States” over “[a]ny civil case of admiralty or maritime jurisdiction.” This grant of jurisdiction is, however, immediately qualified by a clause “saving to suitors in all eases all other remedies to which they are otherwise entitled.” Id. The State argues persuasively that this clause *1241 undermines the district court’s reliance on § 1331(1) to support removal here.
The Supreme Court has noted that the “historic option of a maritime suitor pursuing common-law remedies to select his forum,” which is the object of the savings clause, “would be taken away by an expanded view of § 1331, since savings-clause actions would then be freely removable under § 1441.”
Romero v. Int’l Terminal Operating Co.,
Defendants offer no substantive opposition to this analysis. Instead, they note that their petition for removal alleged several sources for federal jurisdiction that the district court has had no occasion to consider, and suggest that a remand for further proceedings would be the appropriate course in the event we agree with the State that § 1331(1) cannot support removal. 4 The State has responded to this suggestion with a fairly summary argument that none of the alternative bases for federal jurisdiction are meritorious. Given the cursory and collateral nature of the briefing on this decisive issue, we deem it best to remand to permit fuller argument to and consideration by the district court in the first instance.
The order of the district court denying the State’s motion for remand is AFFIRMED insofar as it rejects the State’s assertion of Eleventh Amendment immunity and REVERSED insofar as it relies on § 1331(1) as a source for federal question jurisdiction to support removal. The matter is remanded for further proceedings consistent with this decision.
Notes
. After examining the briefs and appellate record, this panel has determined unanimously to grant the parties' request for a decision on the briefs without oral argument. See Fed. R.App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument.
. In
Wis. Dep't of Corr. v. Schacht,
. There is a body of case law addressing counterclaims asserted against States that have voluntarily brought suit in federal court.

. Defendants also suggest, in summary fashion and without any supporting authority, that the State’s appeal in a related case may render this appeal moot.
