Final.

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.

Whatever the court decides on an issue, their decision is final and can only be changed by another court ruling.

This ultimately implies that, 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).

A supreme court refers to a federal court and it is typically the highest court in relation to the hierarchy of courts in the judicial branch. The appellate jurisdiction of the supreme court simply means that, it has the ability to hear a case on appeal brought by a court of original jurisdiction such as cases relating to federal laws or the constitution.
