Final answer:
An appellate court may remand a case, exercising its appellate jurisdiction to review decisions of lower courts. The U.S. Supreme Court, with both original and appellate jurisdiction, selects cases that typically involve constitutional issues or differing legal interpretations, usually via a writ of certiorari.
Step-by-step explanation:
An appellate court may remand a case and send it back to the original court for consideration. Appellate courts have appellate jurisdiction, which is the power to hear a case after a lower court has already decided on it. This appellate review is often invoked when a party in a case is dissatisfied with the decision of a lower court.
In the United States, the Supreme Court frequently exercises this jurisdiction over cases involving constitutional questions or those that have received differing interpretations of law by various courts.
It's important to note that the Supreme Court is the final court of appeal, and only selects a small fraction of cases for review, generally those with significant legal questions or constitutional implications, through a writ of certiorari.
