Davis v. State (App. 1994)
In Davis v. State, 870 S.W.2d 43 (Tex. Crim. App. 1994) the defendant's general notice of appeal was insufficient to confer jurisdiction on the appellate court to review the trial court's ruling on the motion to suppress. The defendant attempted to file an amended notice of appeal after the court of appeals had handed down its opinion to correct the defect.
The Court noted that "a defendant may not be permitted to amend a notice of appeal out of time." Id. at 47.
