In re Leo Lapuerta, M.D., F.A.C.S., and The Plastic Surgery Institute of Southeast Texas, P.A., 24-0879, April 10, 2026.
On appeal from First Court of Appeals District (01-23-00860-CV), from Harris County, Texas
Synopsis
The Texas Supreme Court conditionally granted mandamus and ordered the trial court to reinstate an 11–1 take-nothing defense verdict because the new-trial order was not supported by a lawful, reasoned basis. The Court held the trial court’s stated reasons were predicated on a misapprehension of Texas “loss of chance”/medical-causation law and forcefully condemned the plaintiff’s use of a dissenting juror’s post-verdict letter describing deliberations as flagrantly improper.
Relevance to Family Law
Texas family-law trial courts also face post-verdict (or post-ruling) pressure to “do over” outcomes—especially after hotly contested custody trials, property-characterization disputes, and fee-shifting fights. This mandamus decision is a reminder that when a trial judge sets aside an adjudicated result (jury verdict in a jury case, or a final judgment after a bench trial) the stated rationale must be legally correct, supported by the record, and insulated from improper juror-deliberation evidence. For family litigators trying jury cases (e.g., limited issues like characterization, tort claims between spouses, or other jury-submitted claims) or defending final judgments from post-trial attacks, Lapuerta is a blueprint for mandamus: target (1) legal error masquerading as “charge confusion” and (2) any attempt to inject juror deliberations into the record.
Case Summary
Fact Summary
Jose Torres suffered a severe bandsaw injury to his right index finger. Dr. Leo Lapuerta, a plastic surgeon, treated Torres, described the fingertip as “hanging by a thread,” recommended amputation, and—after Torres refused—attempted salvage treatment, including later skin flap surgery with grafting on July 11, 2016. Torres later treated with a different surgeon, Dr. Henry, who diagnosed osteomyelitis, attempted debridement, and ultimately performed a ray amputation removing the index finger and metacarpal.
Torres sued, alleging negligent wound care caused an infection necessitating the ray amputation. The defense theory was twofold: (1) the initial trauma left essentially no meaningful chance of salvaging the finger, and (2) Torres’s own post-accident conduct contributed to deterioration (poor hygiene, smoking, travel during treatment, and noncompliance with therapy). Multiple physicians testified that salvaging the finger as a functional finger had a low probability—generally 10% or less (or up to 10–20%).
The jury charge contained an introductory “loss of chance” instruction (requested by the defense) telling jurors that Torres’s finger must have had a greater-than-50% chance of survival with reasonable care for Lapuerta’s negligence to be a proximate cause. During deliberations the jury asked whether the charge related to the whole finger or a partial finger; the court declined to answer. The jury returned an 11–1 defense verdict (no proximate cause as to both Lapuerta and Torres), and a take-nothing judgment was signed.
Torres moved for new trial, re-urging charge objections and attaching a post-verdict letter from the lone dissenting juror describing the deliberations and asserting that missing words (e.g., “or portion thereof”) made the trial “irrelevant.” The trial court granted a new trial and later issued an amended order with seven reasons. The court of appeals denied mandamus. The Texas Supreme Court granted mandamus and directed rendition on the verdict.
Issues Decided
- Whether the trial court abused its discretion by granting a new trial based on reasons “predicated on legal error” concerning Texas medical-negligence causation principles, including “loss of chance” standards.
- Whether mandamus relief is appropriate to correct a new-trial order that lacks a lawful, reasoned basis and risks wasteful duplicative proceedings.
- Whether juror-deliberation evidence (a dissenting juror’s post-verdict letter) is improper and may not be used to support a new-trial effort framed as “charge confusion.”
Rules Applied
- Mandamus standards: abuse of discretion with no adequate remedy by appeal, with particular emphasis that an erroneous new-trial order generally lacks an adequate appellate remedy. See In re Prudential Ins. Co. of Am., 148 S.W.3d 124 (Tex. 2004); In re Rudolph Auto., LLC, 674 S.W.3d 289 (Tex. 2023).
- New-trial orders must provide a lawful, reasoned basis sufficient for appellate review; mandamus lies when stated reasons are legally improper or unsupported by the record. In re Columbia Med. Ctr. of Las Colinas, Subsidiary, L.P., 290 S.W.3d 204 (Tex. 2009); In re Toyota Motor Sales, U.S.A., Inc., 407 S.W.3d 746 (Tex. 2013); Rudolph, 674 S.W.3d at 302.
- “Loss of chance” jurisprudence in Texas medical-negligence causation: the Court treated the trial court’s reasoning as legally erroneous in its understanding/application of the greater-than-50% causation threshold discussed in Columbia Rio Grande Healthcare, L.P. v. Hawley, 284 S.W.3d 851 (Tex. 2009).
- Juror deliberations: evidence describing deliberations is categorically improper; the Court labeled the use of the dissenting juror letter “flagrantly improper evidence.” (The opinion’s language underscores the evidentiary and policy bar against probing juror mental processes and deliberative communications.)
Application
The Court framed the analytic posture aggressively: ordering a new trial contrary to a jury verdict is an “unusually serious act,” and the post-Columbia line of cases requires trial courts to articulate reasons that are both (1) specific and (2) substantively valid. That requirement is not merely procedural; it is the mechanism that allows mandamus courts to police whether a trial judge is correcting genuine error or simply rejecting a verdict.
Here, the trial court purported to grant a new trial based on problems tied to the “loss of chance” instruction and asserted jury confusion. But the Supreme Court concluded the trial court’s reasoning misperceived Texas medical-negligence causation law. In substance, the new-trial rationale turned on an incorrect legal premise about when and how a greater-than-50% survival probability matters to proximate cause in a preexisting-condition context. Because a trial court has “no discretion” to apply the wrong law, a new-trial order built on that legal error is an abuse of discretion.
Separately—and strategically important for trial lawyers—the Court refused to treat the juror letter as harmless background noise. Even though the amended order did not expressly cite the letter, the Court emphasized it would not “ignore the possibility” that this “flagrantly improper evidence influenced the outcome.” In other words, the Court signaled that when a new-trial request is packaged with juror-deliberation narratives to prove “confusion,” the entire new-trial process is tainted, and appellate courts should be skeptical that the trial court’s stated reasons reflect a clean, record-based analysis.
Finally, the remedy was not a remand for more findings. The Court directed the trial court to render judgment on the verdict—confirming that when the new-trial order fails Columbia/Toyota/Rudolph scrutiny, the proper correction is restoration of the jury’s take-nothing result.
Holding
The Court conditionally granted mandamus because the trial court’s new-trial order lacked a lawful, reasoned basis. The order’s stated reasons rested on legal error concerning Texas medical-negligence causation principles (including “loss of chance” standards), which is an abuse of discretion correctable by mandamus.
The Court further condemned the plaintiff’s submission of a dissenting juror’s post-verdict letter recounting deliberations as “flagrantly improper evidence,” and it refused to discount the risk that such material could have influenced the decision to grant a new trial. The Court directed the trial court to render judgment on the jury’s take-nothing verdict.
Practical Application
For Texas family-law litigators, Lapuerta is less about medical causation and more about post-verdict/post-judgment warfare: preserving favorable outcomes, defeating “redo” attempts, and building a mandamus-ready record when a trial court discards an adjudicated result.
- Jury trials in family cases (where available): If you win a jury-submitted issue (e.g., a tort claim between spouses, a contract claim, a characterization issue if properly submitted, or other jury-eligible disputes), Lapuerta supports immediate mandamus scrutiny when a new trial is granted on “charge error” that is actually a legal misread.
- Charge-error arguments must be legally tethered: The Supreme Court’s emphasis is that new-trial reasons cannot be “predicated on legal error.” In family practice, that maps onto recurring “legal standards” disputes—separate-property tracing rules, reimbursement frameworks, contractual alimony enforcement, limitations, fee-shifting predicates, and jurisdictional prerequisites. A trial judge’s incorrect standard cannot supply a “reasoned basis” to undo an adjudicated outcome.
- Juror-deliberation evidence is radioactive: In a family jury trial, the losing side may try to launder deliberation narratives as “misconduct,” “confusion,” or “charge ambiguity.” Lapuerta arms you to object early, move to strike, and—if the court entertains it—seek mandamus on the premise that the new-trial process itself has been infected by improper material.
- Mandamus timing and posture: The Court reiterated that appeal is typically inadequate when a new trial is erroneously ordered because it forces duplicative proceedings. Family cases often involve fast-moving post-judgment leverage; Lapuerta supports treating the new-trial grant as an extraordinary event warranting extraordinary correction.
Checklists
Mandamus-Ready Record When a New Trial Is Granted
- Request written, specific reasons for any new-trial order and confirm the court’s reasons are on the record.
- Obtain the signed new-trial order and any amended order immediately; calendar mandamus deadlines and record requests.
- Ensure the reporter’s record includes: charge conference, objections, tendered instructions, jury notes, and the court’s responses.
- In the mandamus petition, isolate each stated reason and show how it is either legal error or unsupported by the record under Columbia, Toyota, and Rudolph.
Defeating “Jury Confusion” Narratives in Family Jury Trials
- Demand that any “confusion” argument be tied to the charge language and record, not post-verdict speculation.
- Highlight curative tools already used (definitions given, proper refusal to answer substantive jury questions, invited error/waiver).
- Argue harm standards rigorously: show why the complained-of language did not probably cause an improper judgment.
- Preserve error cleanly at the charge conference; do not rely on “everyone knows what we meant” explanations later.
Handling Juror Letters, Emails, and Post-Verdict “Debriefs”
- Move to strike any juror affidavit/letter that describes deliberations, mental processes, or vote dynamics.
- Object that deliberation narratives are improper and cannot be used to prove confusion, misunderstanding, or why the jury voted as it did.
- Request a clear ruling excluding such material and, if necessary, a written order confirming it was not considered.
- Avoid creating your own problem: instruct staff and clients not to solicit juror explanations or deliberation details post-verdict.
Family-Law Use Cases to Watch (High-Risk Post-Trial Motions)
- Property characterization/tracing tried to a jury (or jury-adjacent fact findings): scrutinize any new-trial rationale built on an incorrect legal standard.
- Separate enforcement or contract claims joined with the divorce: watch for “new trial” attempts that repurpose legal arguments as “charge error.”
- Attorney’s fees findings: be prepared to show why the court’s new-trial rationale is outcome-driven rather than record-driven.
- High-conflict custody trials with mixed jury/court issues: compartmentalize what the jury could decide and attack any new-trial order that blurs legal lines.

Family Law Crossover
In a Texas divorce or SAPCR tried to a jury (or involving jury-submitted components), Lapuerta can be weaponized in two directions: as a shield to preserve a favorable verdict, and as a sword to challenge a trial court’s effort to “start over.” If the trial court grants a new trial after a party wins a jury finding relevant to property/tort claims or other jury-eligible issues, Lapuerta supplies the mandamus framing: demand that the order’s reasons be not just stated, but legally correct and record-supported; if the reasons reflect a misread of the governing family-law standard (characterization rules, reimbursement doctrines, limitations, contractual enforcement prerequisites), that legal error itself is mandamus-grade. And if the losing party attempts to prove “jury confusion” through a juror letter or affidavit describing deliberations—common in emotionally charged family cases—Lapuerta gives you strong language to exclude it and to argue that any new-trial ruling even potentially influenced by deliberation evidence is fundamentally unreliable and should be set aside in favor of reinstating the verdict.
