Court of Appeal & Supreme Court Tax Cases UK

The Court of Appeal hears further appeals from the Upper Tribunal on points of law, with permission required. Three further appeals may be possible beyond the FTT, with the Supreme Court as the final instance in the most significant cases. Expert evidence is rarely introduced at this stage, the focus is on legal argument, not fresh factual or expert evidence.
