Alzarka v. State
In Alzarka v. State, 90 S.W.3d 321 (Tex. Crim. App. 2002), the Court held that even though the defendant signed a plea form containing a written waiver of appeal, the defendant had not waived her right to appeal. Id. at 322-24.
The court based this conclusion on the fact that:
(1) the trial court gave express oral permission to appeal;
(2) counsel and the court made several statements agreeing that the defendant would be permitted to bring an appeal;
(3) the State's original appellate brief made no claim that the defendant had waived her right to appeal. Id.
