City of Houston v. Castillo, 14-25-00756-CV, March 12, 2026.
On appeal from the 190th District Court Harris County, Texas.
Synopsis
A plaintiff pleading a Texas Tort Claims Act (“TTCA”) motor-vehicle waiver does not have to affirmatively negate the TTCA’s emergency/911 exceptions unless the petition’s own allegations plausibly implicate an exception. Separately, a Rule 91a motion asserting governmental immunity is treated as a jurisdictional challenge that triggers the mandatory automatic stay of trial-court proceedings under Tex. Civ. Prac. & Rem. Code § 51.014(b), making discovery orders entered during the stay mandamus-vulnerable.
Relevance to Family Law
Family-law litigators routinely intersect with governmental entities (police departments, counties, school districts, state agencies) in SAPCRs and divorces—whether through subpoena practice, body-cam and 911 records, child-protection investigations, constable activity, or tort-adjacent claims folded into family litigation. This opinion is a reminder that when a governmental unit takes an interlocutory immunity appeal (including via Rule 91a), the § 51.014(b) automatic stay is not a technicality—it is a jurisdiction-stripping pause button that can derail discovery timelines, temporary-orders strategy, and trial-court enforcement efforts if not managed carefully.
Case Summary
Fact Summary
The plaintiff alleged a traffic collision on Main Street in Houston caused by a City employee’s negligent operation of a motor-driven vehicle—specifically, disregarding turn signals at an intersection and striking her vehicle. The City responded with a Rule 91a motion to dismiss, contending the petition was legally insufficient because it failed to plead around TTCA exceptions—particularly the emergency/911 response exceptions that can preserve governmental immunity even when the motor-vehicle waiver is otherwise implicated.
The trial court denied the Rule 91a motion. The City pursued an interlocutory appeal and also sought mandamus relief after the trial court entered a discovery order while the appeal was pending. The plaintiff resisted mandamus on the theory that § 51.014(b)’s stay did not apply because the City used Rule 91a rather than a traditional plea to the jurisdiction.
Issues Decided
- Whether a plaintiff must plead facts negating TTCA exceptions (including emergency/911 response) to survive a Rule 91a motion when the petition alleges the TTCA motor-vehicle waiver but does not itself allege emergency-response facts.
- Whether a Rule 91a motion asserting governmental immunity is a jurisdictional challenge that triggers the automatic stay of all trial-court proceedings under Tex. Civ. Prac. & Rem. Code § 51.014(b).
- Whether mandamus relief is appropriate to vacate a discovery order entered during the pendency of the § 51.014(b) automatic stay.
Rules Applied
- TTCA motor-vehicle waiver and exceptions: Tex. Civ. Prac. & Rem. Code § 101.021(1)(A) (waiver for injury arising from operation/use of a motor-driven vehicle), subject to statutory exceptions (including emergency/911 response parameters).
- Pleading standard re: TTCA exceptions: A plaintiff need not negate every TTCA exception unless the petition’s allegations plausibly implicate an exception. Rattray v. City of Brownsville, 662 S.W.3d 860, 868 (Tex. 2023).
- Rule 91a as an immunity/jurisdictional vehicle: Rule 91a motions challenging TTCA immunity are governed by Chapter 51 interlocutory appeal practice. San Jacinto River Auth. v. Medina, 627 S.W.3d 618, 621 (Tex. 2021); City of Dallas v. Sanchez, 494 S.W.3d 722, 725 (Tex. 2016) (per curiam).
- Automatic stay: Tex. Civ. Prac. & Rem. Code § 51.014(b) (stay of trial-court proceedings pending interlocutory appeal of a governmental unit’s jurisdictional challenge).
- Mandamus remedy for orders entered during stay: Trial court abuses discretion by acting during the stay; mandamus is available absent an adequate appellate remedy. See, e.g., In re Univ. of the Incarnate Word, 469 S.W.3d 255, 260 (Tex. App.—San Antonio 2015, orig. proceeding).
- Judicial admissions: Must be “clear, deliberate, and unequivocal” assertions of fact; legal conclusions about immunity generally do not qualify. Wilson v. Fleming, 669 S.W.3d 450, 461 (Tex. App.—Houston [14th Dist.] 2021), aff’d on other grounds, 694 S.W.3d 186 (Tex. 2024).
Application
On the pleading question, the Fourteenth Court treated the case as a straightforward TTCA motor-vehicle-waiver pleading. The plaintiff alleged a City employee negligently operated a motor vehicle and caused a collision—enough to invoke the waiver at the pleadings stage. The City attempted to force an additional pleading burden: that the plaintiff must also affirmatively allege facts disproving the emergency/911 response exceptions. The court declined, applying Rattray: unless the petition itself plausibly suggests the employee was responding to an emergency or 911 call, the plaintiff is not required to plead around that possibility. The court emphasized that the City is not foreclosed from later developing evidence and presenting a jurisdictional challenge (e.g., a plea to the jurisdiction) showing the exception applies; the point is that Rule 91a dismissal is not warranted based solely on an unalleged exception.
On the “judicial admission” argument, the City leaned on a sentence in the petition suggesting that “on the face” the officer “would be protected” by official immunity. The court rejected the argument for two reasons that matter in high-stakes pleading disputes: (1) immunity is a legal conclusion, not a fact susceptible to judicial admission; and (2) the language was conditional/hedged (“would be”), not the type of unequivocal factual concession that collapses a claim.
On the stay/mandamus question, the court treated the City’s Rule 91a motion (because it asserted governmental immunity) as a jurisdictional challenge for Chapter 51 purposes. That classification is outcome-determinative in practice: it means the interlocutory appeal triggered § 51.014(b)’s mandatory stay of all trial-court proceedings. As a result, the discovery order entered during the pendency of the appeal was an abuse of discretion. Because an appeal after final judgment cannot un-ring discovery compelled during a statutory stay, mandamus was the appropriate corrective tool. The court conditionally granted mandamus and directed the trial court to vacate the discovery order.
Holding
The court affirmed the denial of the City’s Rule 91a motion to dismiss, holding the plaintiff sufficiently pleaded a TTCA waiver by alleging injury arising from the negligent operation of a motor-driven vehicle, and the plaintiff was not required to negate the emergency/911 exceptions absent petition allegations that plausibly implicate those exceptions.
In a separate original proceeding, the court conditionally granted mandamus relief, holding that the City’s interlocutory appeal from the immunity-based Rule 91a ruling triggered the automatic stay under Tex. Civ. Prac. & Rem. Code § 51.014(b), and the trial court therefore abused its discretion by entering a discovery order during the stay.
Practical Application
For family-law litigators, the “automatic stay” half of this opinion is the transferable weapon and the transferable risk. When a governmental unit is in your case (or in a related case generating discovery you need), an immunity-based interlocutory appeal can instantly freeze trial-court proceedings—including discovery you were counting on for temporary orders, social-study disputes, or enforcement timelines. Do not assume you can “work around” the stay with agreed orders, expedited settings, or narrowly tailored discovery; if § 51.014(b) applies, orders entered during the stay are prime mandamus targets.
At the same time, if you represent (or are aligned with) a governmental unit—e.g., a county office pulled into third-party practice, or an agency resisting discovery—this opinion reinforces that Rule 91a can be more than a pleading attack: when it asserts immunity, it can create immediate procedural leverage by pausing proceedings and allowing mandamus cleanup of orders entered during the pause.
Substantively, the pleading holding also matters in family-adjacent tort claims that sometimes ride alongside divorce/SAPCR litigation (vehicle collisions involving municipal employees, negligent supervision allegations against governmental actors, or claims against counties). Plaintiffs do not have to anticipate and negate every TTCA exception in the live pleading; defendants must first show the petition plausibly implicates the exception, or else develop evidence for a later jurisdictional challenge.
Checklists
Checklists
When You Need Discovery From a Governmental Unit in a Family Case (or Related Civil Case)
- Identify whether the governmental unit has filed (or can file) an immunity-based Rule 91a motion, plea to the jurisdiction, or other jurisdictional challenge that is appealable under Chapter 51
- Before pushing for contested discovery orders, confirm whether any interlocutory appeal has been perfected that triggers Tex. Civ. Prac. & Rem. Code § 51.014(b)
- If an appeal is pending, assume the stay is broad: treat all trial-court proceedings as stayed unless clearly exempted by statute/case law
- Build alternative proof pathways (third-party subpoenas, non-governmental custodians, admissions, stipulations) that do not require stayed trial-court action against the governmental unit
- Calendar the appellate milestones and coordinate your temporary-orders/trial strategy around the stay’s likely duration
If the Other Side Obtains a Discovery Order During a § 51.014(b) Stay
- Preserve the record immediately (order, transcripts, notice of appeal, docket sheet, filings showing the immunity issue)
- Object on the basis of the automatic stay and lack of authority to proceed
- Consider prompt mandamus—do not wait and hope the issue “washes out” later
- Request vacatur (not modification) of the order entered during the stay; the theory is the order should not exist
- Seek protective relief to prevent production pending mandamus if compliance deadlines are imminent
Pleading Strategy for TTCA-Adjacent Claims (Including Family-Adjacent Tort Claims)
- Plead facts establishing the waiver you need (e.g., motor-driven vehicle operation/use) with enough specificity to be plausible
- Do not volunteer unnecessary allegations that “plausibly implicate” exceptions (e.g., emergency response) unless strategically required
- Avoid “immunity-concession” language in petitions and responses that can be reframed as admissions; keep legal characterizations precise and conditional if needed
- Anticipate that even if you survive Rule 91a, the defense can re-attack with evidence via plea to the jurisdiction later—plan your discovery requests and proof accordingly

Full Opinion
Family Law Crossover
In a divorce or custody case, this ruling can be weaponized procedurally when a governmental entity is a target (or gatekeeper) of high-value discovery—think police body-cam, 911 audio, CAD logs, jail calls, school records, or county-maintained documents relevant to conservatorship or protective orders. If the governmental unit files an immunity-based Rule 91a motion and takes an interlocutory appeal, § 51.014(b) can freeze the trial-court engine: opposing counsel’s discovery motion practice, compelled-production orders, and even enforcement-style proceedings can become voidable by mandamus if pursued during the stay.
Strategically, that means (1) the party aligned with the governmental unit can use an immunity appeal to disrupt momentum before a temporary-orders hearing or trial, and (2) the party who needs the records must shift immediately to stay-resistant options—negotiated productions without court compulsion, third-party custodians, or proof substitutes—because “getting an order anyway” is exactly how you manufacture a mandamus loss and waste critical calendar time in a family case.
