Thomas J. Davis, Appellant v. the State of Texas

Summary

The Court of Criminal Appeals held that Texas Code of Criminal Procedure Article 42.12 §5(b) bars any appeal of a trial court's determination to adjudicate guilt, including jurisdictional claims such as a denial of counsel at a supervision‑extension hearing. Accordingly, the Court reversed the Court of Appeals and affirmed the trial court's adjudication. A concurring opinion noted that the claim may still be raised in a post‑conviction habeas petition.
