Tex. R. App. P. 42.3 (2026)

Under the following circumstances, on any party's motion — or on its own initiative after giving ten days' notice to all parties — the appellate court may dismiss the appeal or affirm the appealed judgment or order. Dismissal or affirmance may occur if the appeal is subject to dismissal:

(a) for want of jurisdiction;

(b) for want of prosecution; or

(c) because the appellant has failed to comply with a requirement of these rules, a court order, or a notice from the clerk requiring a response or other action within a specified time.
