COA07 — February 6, 2026
In Lamas v. State, the appellant attempted to appeal his conviction for sexual assault of a child nearly four years after his 2022 sentencing. The Seventh Court of Appeals analyzed the case under Texas Rule of Appellate Procedure 26.2(a)(1), which requires a notice of appeal to be filed within 30 days of sentencing (or 90 days if a motion for new trial is filed). Because the appellant missed this mandatory deadline by several years, the court determined it lacked jurisdiction to hear the merits of the appeal. Following the precedent in Castillo v. State, the court held that a timely notice of appeal is a jurisdictional necessity, and dismissed the case for want of jurisdiction.
Litigation Takeaway
“For family law practitioners, this case confirms that an untimely criminal appeal does not stop a conviction from being considered 'final' for parental termination purposes. If a parent files a late notice of appeal years after the fact to delay termination proceedings, that filing is a jurisdictional nullity and should not prevent the court from proceeding with the 'Best Interest' phase of the case.”
