The Court of Appeal is designated as a 'senior court' under the Senior Courts Act 1981. While the Supreme Court hands down the most authoritative judgments, it is not named as a 'senior court' by this Act. The senior courts include the Court of Appeal, the High Court, and the Crown Court.

Key Point: The classification of senior courts helps in understanding the structure and hierarchy within the judicial system, with the Court of Appeal being one of the key appellate courts.
