You can think of the Court of Appeal like a high court that makes big decisions. The Court of Appeal must sit as a full court to hear and determine certain cases, like those that are very important or have been referred by another court. This can include appeals from the Court Martial Appeal Court under section 10 of the Court Martial Appeals Act 1953. You might wonder what a full court is. A full court of the Court of Appeal has 5 Judges. These Judges must be holding office under section 45(2). The Court of Appeal will decide which cases are important enough to be heard by a full court, using a procedure set out in section 51. They will also hear cases that have been referred by another court, like those under section 47(4). This is how the Court of Appeal makes sure important cases get the attention they need.
