Opinion for the Court filed by Circuit Judge ROGERS.
The Kickapoo Tribe of Indians of the Kickapoo Reservation in Kansas appeals from the grant of summary judgment to the Secretary of Interior and the Assistant Secretary of Interior for Indian Affairs (“the Secretary”). The Tribe contends that the district court erred in ruling that, although a compact between the Tribe and the Governor of Kansas had been approved by operation of law under the Indian Gaming Regulatory Act (“Gaming Act”), 25 U.S.C. § 2710(d)(8)(C), the compact was nevertheless invalid because the Governor lacked the authority under state law to sign the compact on behalf of the State of Kansas. We conclude, in agreement with the Secretary, that the district court abused its discretion in denying the Secretary’s motion to dismiss the complaint because Kansas was an indispensable party under Rule 19(b) of the Federal Rules of Civil Procedure. Accordingly, we reverse and remand with instructions to dismiss the complaint.
I.
The Gaming Act authorizes Indian tribes and states to enter into “Tribal-State compacts” setting forth the terms under which a tribe may conduct certain forms of gambling on its reservation. 25 U.S.C. §§ 2701-21 (1988). A compact must be submitted to the Secretary of the Interior, who shall approve or disapprove it within forty-five days; if the Secretary fails to act within that period, the compact is deemed approved. Id. § 2710(d)(8)(C). Thereafter, the Secretary is required to publish notice of the approved compact in the Federal Register. Id. § 2710(d)(8)(D).
In January 1992, the Chairman of the Kickapoo Tribe of Indians of the Kickapoo Reservation in Kansas and the Governor of Kan *1494 sas entered into a compact authorizing Class III gambling on the Kickapoo Reservation in Kansas. 1 Shortly after the Tribe forwarded the compact to the Secretary of the Interior, the Attorney General of Kansas challenged the Governor’s authority under Kansas law to negotiate and enter into the compact, by filing a petition for mandamus in the Supreme Court of Kansas. In the interim, in response to the Secretary’s position that the compact did not comply with the Gaming Act, the Tribe and the Governor revised the compact on grounds unrelated to the Attorney General’s lawsuit and resubmitted the compact to the Secretary. Because of the litigation brought by the Kansas Attorney General, however, the Secretary notified the Governor and the Tribe that the compact “had not been submitted as ... required by 25 U.S.C. § 2710(d)(8),” and that the Gaming Act’s forty-five-day review period would be tolled until the Supreme Court of Kansas resolved the question of the Governor’s authority.
The Tribe sued the Secretary seeking a declaratory judgment that the Secretary lacked authority to defer approval of the compact and that his failure to disapprove it within forty-five days resulted in approval of the compact as a matter of law. The Tribe also sought a writ of mandamus directing the Secretary to publish notice of the compact in the
Federal Register.
After the Supreme Court of Kansas interpreted state law as allowing the Governor to negotiate a compact under the Gaming Act but precluding the Governor from signing the resulting compact and thereby binding the State to its terms,
State ex rel. Stephan v. Finney,
The district court denied the Secretary’s motion to dismiss, ruling that the state legislature’s failure to enter into a compact with the Tribe and the assumption that the Governor negotiated and signed the compact with “the best interests of the State in mind” meant that the State of Kansas was not an indispensable party and the litigation could proceed in its absence.

Under Fed.R.Civ.P. 19, whether a party is indispensable for a just adjudication requires a determination regarding whether the absent party is necessary to the litigation; if so, whether the absent party can be joined in the litigation; and if joinder is infeasible, whether the lawsuit can nevertheless proceed “in equity and good conscience.” Fed.R.Civ.P. 19;

v. Harbor Ins. Co,
A.
The Tribe seeks to obtain the validation of a compact with the State of Kansas that the Supreme Court of Kansas has held was not approved by an official empowered to do so under state law.
State v. Finney,
One reason joinder may be infeasible is that the absent party enjoys sovereign immunity.
See Quileute Indian Tribe v. Babbitt,
Consequently, the issue faced by the district court was whether “in equity and good conscience” the Tribe’s lawsuit could proceed in the absence of the State of Kansas or whether the lawsuit should be dismissed because Kansas was an indispensable party. While Rule 19(b) sets forth four non-exclusive factors for the court to consider,
see supra
note 2, this court has observed that “there is very little room for balancing of other factors” set out in Rule 19(b) where a necessary party under Rule 19(a) is immune from suit because immunity may be viewed as one of those interests “compelling by themselves.”

The exercise of discretion contemplates reasoned decision making on the basis of relevant and appropriate considerations to the task at hand.
See generally Langnes v. Green,
The district court found that the first two factors enumerated in Rule 19(b) — prejudice to Kansas from a judgment for the Tribe and inability to tailor a judgment to lessen or avoid the prejudice — favored dismissal, but that the two remaining factors — the adequacy of a judgment in Kansas’ absence and the lack of an adequate remedy for the Tribe— plus two additional factors dictated that the lawsuit could proceed notwithstanding Kansas’ absence.
Kickapoo Tribe,
While appropriately finding that Kansas would be prejudiced by a judgment rendered in its absence,

the district court concluded that the prejudice was mitigated by two considerations. First, the State of Kansas knew of the Tribe’s lawsuit but it did not intervene.
*1498
Id.
at 41. Second, granting relief to the Tribe would only subject the State to obligations to which the “popularly elected” Governor, the State’s highest executive official, had already agreed and obligations countenanced by Congress under the Gaming Act.
Id.
at 41^42. Each consideration was flawed, however. Failure to intervene is not a component of the prejudice analysis where intervention would require the absent party to waive sovereign immunity.
See Wichita & Affiliated Tribes,
Because the district court concluded that Kansas would be prejudiced by a judgment rendered in its absence, and that, in view of the relief sought by the Tribe, “there is no way the court can avoid the prejudice,”
Kickapoo Tribe,
First, the district court found that the Tribe lacked “any other remedy” if the instant lawsuit were to be dismissed.
Kickapoo Tribe,
Second, the district court reinvoked the assumption that the Governor entered the compact with State’s best interests in mind as an independent ground under Rule 19(b) supporting the retention of jurisdiction.
Kickapoo Tribe,
Finally, the district court concluded that the apparent failure of the Kansas legislature to negotiate in good faith with the Tribe supported the retention of jurisdiction.
Id.
While the court might understandably have been concerned by indications that Kansas was stonewalling efforts by the Tribe to reach agreement on a compact, reliance on this consideration as a basis to retain jurisdiction was inappropriate. Not being joined in the litigation, Kansas could not respond to the court’s concern about the State’s conduct and the Secretary was not in a position to champion the State’s position in view of his trust obligations to the Tribe.
See Heckman v. United States,
C.
While the 1966 amendment of Rule 19 was designed to emphasize the practical considerations that underlie the determination of whether to proceed,
see
Charles A. Wright, Law of Federal Courts 498-99 (5th ed.
*1500
1994), Kansas’ indispensability as a party in the Tribe’s lawsuit is hardly a formality; not only its contractual rights are at issue but its fiscal interests are also potentially at stake.
See State v. Finney,
The situation cannot be salvaged, as the Tribe suggests, under the public interest exception to Rule 19. Stated briefly, this exception provides that when litigation seeks vindication of a public right, third persons who could be adversely affected by a decision favorable to the plaintiff are not indispensable parties.
See National Licorice Co. v. NLRB,
Accordingly, we reverse the grant of summary judgment and remand the case to the district court with instructions to vacate the entry of judgment for the Secretary and to dismiss the complaint without prejudice.
Notes
. Class III gaming includes all gaming, other than social games for minor prizes and bingo, and other comparable games, such as banking card games and “electronic or electromechanical facsimiles of any game of chance or slot machines of any kind.” 25 U.S.C. § 2703(7)(B) & (8).
. An absent party is necessary to the litigation under Fed.R.Civ.P. 19(a) if:
(1) in [the party’s] absence complete relief cannot be accorded among those already parties, or (2) [the party] claims an interest relating to the subject of the action and is so situated that the disposition of the action in [the party's] absence may (i) as a practical matter impair or impede [the party's] ability to protect that interest or (ii) leave any of the persons already parties subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations by reason of [the party’s] claimed interest.
*1495 Where an absent party cannot be made a party, Fed.R.CivP. 19(b) instructs the court to determine:
whether in equity and good conscience the action should proceed among the parties before it, or should be dismissed, the absent [party] being thus regarded as indispensable. The factors to be considered by the court include: first, to what extent a judgment rendered in the [party’s] absence might be prejudicial to [that party] or those already parties; second, the extent to which, by protective provisions in the judgment, by the shaping of relief, or other measures, the prejudice can be lessened or avoided; third, whether a judgment rendered in the [party’s] absence will be adequate; fourth, whether the plaintiff will have an adequate remedy if the action is dismissed for nonjoinder.
. The Secretary did not file a cross appeal from the denial of his motion to dismiss under Rule 19, but he argues in his brief that the denial was an abuse of discretion. The Tribe maintains that the failure to cross appeal precludes the Secretary from arguing that the district court abused its discretion in denying the Rule 19 motion. Even if that were so,
see Massachusetts Mutual Life Ins. Co. v. Ludwig,
. The court reviews determinations under Rule 19(a)(2)(ii) de novo.
See Western Md. Ry.,

See Ponca Tribe of Okla. v. Oklahoma,
. There is general agreement among several circuit courts that Congress intended to abrogate the states’ Eleventh Amendment immunity in enacting § 2710(d)(7) of the Gaming Act vesting jurisdiction in the district court of lawsuits by Indian tribes alleging bad faith by states in compact negotiations. But there is a split among the circuits on whether Congress has authority to abrogate state immunity when it legislates pursuant to the Indian Commerce Clause.
Compare Ponca Tribe,
.The district court did not consider, and neither party has addressed on appeal, whether Kansas could have made a special appearance without waiving its immunity. Hence, we do not consider the issue.
See Miller v. Avirom,
.
Cf. Confederated Tribes of the Chehalis Indian Reservation v. Lujan,
. The inquiry as to prejudice under Rule 19(b) is the same as the inquiry under Rule 19(a)(2)© regarding whether continuing the action will impair the absent party's ability to protect its interest.
See Confederated Tribes v. Lujan,
. Nor can the Tribe persuasively maintain that § 14 of the compact, authorizing the Tribe to oversee law enforcement obligations should the State decline to exercise this authority, eliminates "any possibility of prejudice” approval of the compact would cause to Kansas "in its ability to oversee gaming conducted within its borders.”
Kickapoo Tribe,
. The record before the district court indicated that the Tribe's lawsuit against Kansas was pending on appeal by the State following the district court’s denial of the State's motion to dismiss on immunity grounds.
Kickapoo Tribe,
. The Advisory Committee on the Federal Rules of Civil Procedure, in its Note on the 1966 Revision of Rule 19, stated that "[t]he fourth factor, looking to the practical effects of a dismissal, indicates that the court should consider whether there is any assurance that the plaintiff, if dismissed, could
sue effectively
in another forum where better joinder would be possible.” (emphasis added).
