Appeal from the United States District Court for the Western District of Texas
USDC No. 1:21-CV-95
______________________________
Before Willett, Engelhardt, and Douglas, Circuit Judges. Don R. Willett, Circuit Judge:
Several owners of shoreline property along Lake Austin (the Homeowners) sued the City of Austin over a 2019 ordinance declaring that their properties were—and always had been—within Austin's full-purpose jurisdiction. Nearly six years later, the district court still has not ruled on all the City's grounds for dismissal, let alone the merits. This is the case's second trip to our court. After we previously reversed and remanded, the district court abstained under Pullman from ruling on the Homeowners' United States Court of Appeals

claims. That was error. The Homeowners raise a federal equal-protection claim—that Austin subjects them to full-purpose taxation but provides fewer services than other full-purpose residents receive—and that claim does not depend on any disputed question of Texas law. We REVERSE and
REMAND.
I. Background This dispute concerns several properties along Lake Austin. In 2019, the City adopted an ordinance that (1) declared that the properties had always been within the City's full-purpose jurisdiction, (2) repealed a 1986 Ordinance whose caption declared those properties to be within the City's limited-purpose jurisdiction and provided that they would not be taxed until city services were provided,1and (3) subjected them to full taxation "because they are within City limits."
The Homeowners sued, alleging that the 2019 Ordinance violates federal and state law. The City moved to dismiss the case on several grounds. The district court dismissed all claims without prejudice under the Tax Injunction Act.2On appeal, we reversed as to all but two of the Homeowners' claims.3

On remand, the City reasserted its remaining grounds for dismissal:
(1) the political-question doctrine, (2) Pullman abstention,4(3) Burford abstention,5and (4) failure to state a claim under Rule 12(b)(6).6The magistrate judge recommended abstention under Pullman but did not address the City's other grounds for dismissal. Over the Homeowners' objection, the district court adopted that recommendation and dismissed the claims without prejudice. The court then entered final judgment, and the Homeowners appealed.
II. Mootness The City argues that the case is moot because Senate Bill 1844, passed by the Texas Legislature in 2025, provides a statutory mechanism for disannexation from the City.7
"A case becomes moot—and therefore no longer a 'Case' or 'Controversy' for purposes of Article III—'when the issues presented are no longer "live" or the parties lack a legally cognizable interest in the outcome.'"8But any "concrete interest, however small," keeps the dispute _____________________
4
alive.9The party asserting mootness "bears the burden of coming forward with the subsequent events that have produced that alleged result."10 The case is not moot.
First, S.B. 1844 provides that "the landowners of the area" adjacent to a navigable waterway "are not eligible for a refund of taxes or fees."11Any tax refund must be pursued through Texas's tax-protest regime.12But the Travis County Appraisal District cannot adjudicate whether these properties lie within the City's taxing jurisdiction, and the City cannot be joined in such a proceeding.13The Homeowners therefore retain a financial stake in the validity of the 2019 Ordinance.14
Second, S.B. 1844 does not provide for automatic disannexation. The Homeowners say the City has "partially disannexed the properties of 127 Homeowners" and "rejected 31 Homeowners' valid requests for disannexation." The City has not shown otherwise. For those Homeowners, _____________________

a declaration that the 2019 Ordinance is unlawful could still determine whether their properties remain within the City's full-purpose jurisdiction.
III. Pullman Abstention We turn next to Pullman abstention. We review de novo whether Pullman's legal requirements are met, and we review the district court's weighing of the equities for abuse of discretion.15 This case does not warrant Pullman abstention. The Homeowners allege that the City violates the Equal Protection Clause by treating them as full-purpose residents for taxation but not for municipal services. That federal claim does not turn on any disputed question of Texas law. The district court therefore erred in abstaining.
A. Pullman's Requirements
Under Railroad Commission of Texas v. Pullman Co., a federal court may, in narrow circumstances, defer deciding a federal constitutional claim while an uncertain state-law issue is resolved.16Because "[a]bstention from the exercise of federal jurisdiction is the exception, not the rule," it should be rare.17We have described Pullman as requiring two things: "(1) a federal constitutional challenge to state action and (2) an unclear issue of state law that, if resolved, would make it unnecessary for us to rule on the federal _____________________
6
constitutional question."18Only the second is disputed here, and it has two parts.19
First, the state-law issue must matter to the federal claim. That is, resolving it must "render unnecessary or substantially modify the federal constitutional question."20
Second, the state-law issue must be genuinely uncertain—a "difficult and unsettled" question.21The Supreme Court has described this inquiry as one of legal ambiguity,22which requires an "uncertainty of meaning . . . that gives rise to any of two or more quite different but almost equally plausible _____________________
7
interpretations."23Mere disagreement between the parties does not make state law uncertain.24
Pullman sets a high bar—and does so on purpose.25It applies "only in narrowly limited" circumstances.26Abstention is not appropriate simply because no state court has yet provided a definitive answer to a state-law question.27State-court silence does not make a question "difficult and unsettled." If ordinary interpretive tools yield a discernible answer,28the law is not uncertain, and the federal court should answer the question—not abstain so a state court can answer it first.29
Even when those rigorous requirements are met, Pullman abstention remains discretionary. It "is not an automatic rule applied whenever a federal _____________________

court is faced with a doubtful issue of state law; it rather involves a discretionary exercise of a court's equity powers."30And in exercising that discretion, a court may consider how long the case has been pending.31
B. Pullman Does Not Apply Here
The parties dispute the meaning and effect of the 1986 Ordinance. The Homeowners argue that the 2019 Ordinance unlawfully repealed it. The 1986 Ordinance is captioned as "DECLARING THE LIMITED
PURPOSE JURISDICTION STATUS OF ALL SHORELINE
PROPERTIES." Its body states that "the City of Austin has not regularly and routinely provided comparable municipal services" to those properties, that they "have never been taxed by the City of Austin," and that "certain services normally provided in limited purpose jurisdiction areas . . . have been long provided in this area." The Homeowners argue that those provisions established their properties' limited-purpose status, making the 2019 Ordinance unlawful under several federal and state laws. The City reads the Ordinance differently. It argues that the body never expressly placed the shoreline properties in the City's limited-purpose jurisdiction. It also says the caption is irrelevant because a title does not bear on a law's meaning.32

The district court found the 1986 Ordinance unclear because its body does not expressly address the shoreline properties' jurisdictional status. It also suggested that the Ordinance might violate the Texas Constitution's requirement that all property taxation be "equal and uniform."33But the district court did not apply ordinary rules of statutory construction to determine what the 1986 Ordinance means. Nor did it decide whether the 1986 Ordinance is "fairly subject" to a construction that violates the Texas Constitution.34
We need not resolve those state-law disputes. Whatever the 1986 Ordinance means, the Homeowners' equal-protection claim does not turn on it—so its meaning cannot control the Pullman question before us. The Homeowners claim that Austin taxes their properties as if they were within its full-purpose jurisdiction but denies them the services that go with that status.35Whether they can recover back taxes or obtain disannexation may affect their state-law claims and remedies. But those questions do not answer whether the Fourteenth Amendment permits Austin to impose those taxes while withholding those services. The district court disagreed. It reasoned that the equal-protection claim "would be rendered moot by a state-court determination that, under state law . . . the provision of municipal services to the shoreline properties _____________________
10
was not required here." But whether Texas law required the City to provide those services is a different question from whether the Fourteenth Amendment lets the City tax without providing them.36Pullman therefore does not apply.
We do not decide whether the Homeowners will prevail on their equal-protection claim. We hold only that Pullman abstention was not a proper basis for declining to decide it. If the claim fails, the district court can say so on the merits.
The district court dismissed the entire case on Pullman grounds without reaching the City's other defenses. But because Pullman does not permit abstention on the equal-protection claim, the judgment cannot stand. We therefore reverse and remand the entire case.37
* * *
The Homeowners filed this suit in January 2021. It is still at the pleading stage. The district court has twice dismissed it on threshold grounds without reaching the City's remaining defenses or the merits. We reversed the first dismissal in substantial part. We reverse the second today. Three grounds remain undecided: the political-question doctrine, Burford abstention, and Rule 12(b)(6).

The Homeowners ask us to remand with instructions to reach the merits. We decline because "we are a court of review, not first view."38We express no view on the City's remaining grounds for dismissal. On remand, the district court should address those grounds in the first instance—and together, rather than send this case back to us one threshold issue at a time. As to Burford, we note only that abstention remains a narrow exception to the
"virtually unflagging obligation" of federal courts to exercise the jurisdiction Congress has given them.39
IV. Conclusion This case is not moot. S.B. 1844 neither refunds the Homeowners' taxes nor automatically disannexes their properties, so they retain a concrete stake in the validity of the 2019 Ordinance.
The district court erred in abstaining under Pullman. No matter how the 1986 Ordinance is read, the Homeowners' federal equal-protection claim does not depend on resolving a disputed question of Texas law. The district court should have decided it.
We REVERSE the district court's judgment and REMAND for consideration of the City's remaining grounds for dismissal. _____________________
