Notice of Appeal Extension of Time In Texas
In a criminal case, appeal is perfected by timely filing a notice of appeal. TEX. R. APP. P. 25.2(a).
The notice of appeal must be filed within 30 days after the day sentence is imposed or after the day the trial court enters an appealable order, unless a timely motion for new trial is filed. TEX. R. APP. P. 26.2(a).
The time for filing a notice of appeal may be extended for 15 days under certain circumstances. TEX. R. APP. P. 26.3.
If an appeal is not timely perfected, a court of appeals does not have jurisdiction to address the merits of the appeal, and can take no action other than to dismiss the appeal. Slaton v. State, 981 S.W.2d 208, 210 (Tex.Crim.App. 1998).
There is no constitutional right to appellate review of criminal convictions. Perez v. State, 938 S.W.2d 761, 762 (Tex.App.--Austin 1997, pet. ref'd).
The right to appeal is conferred by the legislature, and a party may appeal only that which the legislature has authorized. Id.
