If you are involved in an appeal under section 133, you can ask the Court of Appeal if you can appeal to them about a decision made by the High Court. The Court of Appeal will only let you do this if they give you permission. You can appeal to the Court of Appeal about a decision the High Court made on a question of law. The Court of Appeal has the same power as the High Court to make decisions on your appeal. The Court of Appeal's decision on your appeal is final, and they also make the final decision on whether to let you appeal to them in the first place, as stated in the appeal process that can be found by following the link to section 133.
