In 2020 the City of Austin approved a light rail plan, Austin voters approved a ballot measure to raise property taxes for it, and the City formed Austin Transit Partnership (ATP) to implement the project and issue the bonds.¹ After taxpayers sued to stop the bond issuance, the City and ATP filed a petition under the Expedited Declaratory Judgment Act (EDJA) for declarations that they may assess and spend the taxes and that ATP may issue bonds, and the taxpayers' suit was consolidated with that action.² The Attorney General, who has a statutory right to participate in EDJA cases, filed a plea to the jurisdiction arguing that neither the City nor ATP is an "issuer" under the EDJA.³

At a hearing on the plea, ATP's counsel urged the district court not to deny the plea because a denial would trigger an interlocutory appeal and an automatic stay, and asked it to take the plea under advisement and proceed to trial; the court agreed, ended the hearing without ruling, and on the morning of trial told the State it had not ruled for or against the plea and called the case to trial.¹ The Attorney General noticed an interlocutory appeal under Section 51.014(a)(8), contending that proceeding to trial implicitly denied the plea, and the Fifteenth Court of Appeals dismissed the appeal for lack of an appealable order.² The vehicle in this Court is a petition for review filed by the Attorney General, which asks in the alternative that it be treated as a petition for writ of mandamus; the Court heard argument on February 10, 2026, and decided the case on May 22, 2026.³ Justice Sullivan did not participate.⁴

Petition for review from the Fifteenth Court of Appeals, construed as a petition for writ of mandamus; argued February 10, 2026, and decided May 22, 2026.⁵

The Attorney General presents one issue:¹ whether the court of appeals erroneously decided it lacked appellate jurisdiction over an interlocutory appeal from a trial court's refusal to rule on a plea to the jurisdiction, where the trial court expressly refused to rule and proceeded to trial. The City and ATP restate the issues as whether the court of appeals had statutory interlocutory jurisdiction where the trial court issued no order and took the plea under advisement, and whether a mislabeled merits challenge to their statutory standing as "issuers" confers interlocutory jurisdiction.²

Mandamus relief is appropriate when a petitioner demonstrates a clear abuse of discretion and has no adequate remedy by appeal.¹ Whether the court of appeals had appellate jurisdiction turned on the plain meaning of Section 51.014(a)(8), which requires an "order" that "grants or denies a plea to the jurisdiction".²

Whether the refusal to rule was an appealable order.

Attorney General (Petitioner): A trial court that reaches the merits before resolving a plea to the jurisdiction implicitly denies it under Thomas v. Long, because a court may not reach the merits without resolving a jurisdictional argument, so the Fifteenth Court's contrary holding flouts precedent and deepens a split among the courts of appeals.¹ In reply, he adds that Respondents do not dispute the split and read Thomas too narrowly.²

City of Austin and ATP (Respondents): The court of appeals correctly dismissed because there was no order granting or denying the plea or ruling on the merits, and the trial court explicitly and repeatedly said it was taking the plea under advisement; the EDJA directs courts to try bond-validation suits with the least possible delay, and the Attorney General's challenge to their status as "issuers" is a merits question of statutory standing, not jurisdiction.³

Whether the Court may treat the petition as one for mandamus.

Attorney General (Petitioner): In the alternative, the Court should treat the petition as a petition for writ of mandamus.⁴

City of Austin and ATP (Respondents): The State delayed too long in seeking mandamus, raising it first in its motion for rehearing in the court of appeals.⁵

The Attorney General argued that the courts of appeals are split on a question of statewide importance, with the Eleventh and Thirteenth Courts holding that refusing to rule and reaching the merits implicitly denies the motion and the Twelfth, Fourteenth, and Fifteenth Courts holding it does not.¹ The City and ATP answered that this is not the case it is represented to be, because sovereign immunity is not at issue and there is no split.²

• Implicit denial. The State's counsel said precedent holds a trial court implicitly denies a plea by starting trial without resolving it, and the order date here is the oral ruling to proceed. (Oral Argument, 0:01:50; 0:03:34)
• Mandamus alternative. The City's counsel said the State could have sought mandamus rather than an interlocutory appeal, if it truly thought the ruling was a miscarriage of justice. (Oral Argument, 0:27:33)
• Written orders. Asked why the statute says "written order" if order always means written, the State's counsel said it did not have to, though most orders are signed and written. (Oral Argument, 0:09:00)
• Why not mandamus now. Asked why the State could not file mandamus in the five minutes before trial, its counsel said the trigger is commencing trial, not scheduling it. (Oral Argument, 0:10:07)
• Jurisdictional inquiry. The City's counsel said a trial court can tell whether an inquiry is jurisdictional, and that the Court has already addressed the question, so sending it down is unnecessary. (Oral Argument, 0:21:32; 0:23:18)
• Purpose of the delay. The City's counsel said it is unusual for a party to say "here's my issue, but don't decide it," and suggested the State did not want trial to go forward. (Oral Argument, 0:26:09; 0:28:54)
• Rebuttal on "order." On rebuttal, the State's counsel said "order" in subsection (a) does not always mean a written order, and the rule's reference back to subsection (d) is consistent. (Oral Argument, 0:40:05)
• Directing the trial court. Asked to whom mandamus would be directed if the trial court intentionally did not rule, the State's counsel said probably the trial court, and offered to write more on it. (Oral Argument, 0:47:48; 0:48:39)

Holding

A district court's refusal to rule on a plea to the jurisdiction is not an "order" that "grants or denies" the plea under Section 51.014(a)(8), so the court of appeals lacked appellate jurisdiction, but a trial court may not decline to rule on a jurisdictional challenge in order to prevent the government's appeal, and mandamus is the appropriate remedy, so the Court construed the petition as one for mandamus and conditionally granted relief directing the trial court to rule.¹ The Court expressed no view on the State's jurisdictional arguments.²

Reasoning

The trial court's approach was improper. A court must determine at its earliest opportunity whether it has authority to decide the case and "may not move to the merits if even one jurisdictional argument remains unresolved," so proceeding to trial without resolving the plea abused the court's discretion to manage the case.³ The City and ATP's point that Section 51.014(a)(8)'s automatic stay can frustrate the EDJA's goal of speed is "not an immaterial concern," but the solution is to deny the plea quickly so the appeal can begin, to expedite the appeal, and to sanction bad-faith or frivolous filings, not to deny the government its statutory appellate rights.⁴

No appealable order. The plain meaning of an "order of a district court" that "grants or denies a plea to the jurisdiction" does not include a case where the court issued no order and expressly refused to rule, and Thomas v. Long is distinguishable because there the trial court issued a written order on a motion containing a jurisdictional challenge, gave no statement that it was not ruling on the jurisdictional issue, and ruled on the merits.⁵ A court's refusal to render an order may function as a denial in practice, but the statute requires an order.⁶

Mandamus. Mandamus is appropriate because a trial court clearly abuses its discretion by refusing to rule on a governmental unit's jurisdictional argument and there is no adequate remedy by appeal when the refusal deprives the unit of its statutory right to interlocutory review.⁷ The Court rejected the argument that the State waited too long, noting it generally treats an improper appeal as a proper mandamus instead of requiring it to be done twice.⁸ The Court also noted that Texas Rules of Appellate Procedure 44.4, 27.2, and 43.6 may let a court of appeals direct a trial court to correct such an error in future cases.⁹

Disposition

The petition for review is construed as a petition for writ of mandamus and conditionally granted, directing the district court to rule on the plea to the jurisdiction, with the writ to issue only if it does not, and the court of appeals' judgment is undisturbed.¹⁰
