COA13 — January 29, 2026
In Gutmann v. Hennig, the Thirteenth Court of Appeals addressed a situation where a trial court's 'sua sponte' severance of a partial summary judgment created a 'two-front war,' forcing parties to litigate in both trial and appellate courts simultaneously. The Appellee, who had won the summary judgment, requested that the appellate court reverse his own victory and vacate the severance to save costs and promote judicial economy. The court analyzed Texas Rule of Appellate Procedure 25.1(c), which allows an appellate court to grant an appellee more favorable relief than the trial court did for 'just cause.' Finding that the parties' mutual desire for efficiency and the Appellant's lack of opposition constituted just cause, the court reversed the summary judgment without reaching the merits and vacated the severance order, effectively reconsolidating the case for a single trial.
Litigation Takeaway
“A 'win' in the form of a partial summary judgment can become a liability if a severance forces you to defend that win on appeal while simultaneously litigating the rest of the case at the trial level. If the costs of fragmented litigation outweigh the benefit of the judgment, parties can use Texas Rule of Appellate Procedure 25.1(c) to seek a 'consensual remand'—reversing the summary judgment and vacating the severance to reconsolidate the estate's litigation into a single, more cost-effective proceeding.”
