Question

Is the supreme court a trail court?​

Answer 1

Answer 2

Although the Supreme Court may hear an appeal on any question of law provided it has jurisdiction, it usually does not hold trials. Instead, the Court's task is to interpret the meaning of a law, to decide whether a law is relevant to a particular set of facts, or to rule on how a law should be applied.
