Answer:
When the supreme court wants to hear a case they issue a summon.
Step-by-step explanation:
Summons: This is a paper that tells a defendant that he or she is being sued and asserts the power of the court to hear and determine the case. A form of legal process that commands the defendant to appear before the court on a specific day and to answer the complaint made by the plaintiff.
The Supreme Court functions as a last resort tribunal. Its rulings cannot be appealed. It also decides on cases dealing with the interpretation of the constitution. (for example, it can overturn a law passed by Congress if it deems it unconstitutional)
