U.S court of appeals.
Explanation:
Judicial power can be defined as the power given to the courts to act and pronounce judgment on a case after making a decision with respect to the parties that brought the case for litigation. Therefore, when a judge presiding over a court of competent jurisdiction gives a verdict or judgment on a case, his or her decision is final and can only be upturned by a higher court such as a court of appeal (appellate court) and supreme court.
An appellate court is also known as court of appeals and can be defined as a court of law of the judicial system that is empowered by law (jurisdiction) and saddled with the responsibility of hearing and reviewing an appeal of a trial-court or other lower court (tribunal).
This ultimately implies that, all appellate courts are empowered by law to review both questions of fact and questions of law. The appellate court can review questions of law as "De novo" or plenary review (legal error standard).
Hence, the court which completes the diagram is the U.S court of appeals.
