Which statement best defines appellate jurisdiction?

• A. The power to review the decision of a lower court.
• B. The power to decide a case when it is first heard by a judge or a jury.
• C. The power of the court to enforce its decision over a party to a lawsuit.
• D. The area governed by the legislative unit that created the court's jurisdiction.

Answer: (A)

Appellate jurisdiction is the power of a higher court to review the decision of a lower court, rather than to hear a case for the first time. This authority lets the higher court correct legal errors, interpret laws, and ensure consistent application of standards across the system. The option that describes reviewing a lower court’s decision captures this function precisely.

The other descriptions fit different concepts. Deciding a case when first heard by a judge or jury describes original or trial jurisdiction, not appellate. Power to enforce a court’s decision concerns execution or enforcement of judgments, not review. The area governed by the legislative unit that created the court’s jurisdiction refers to jurisdictional boundaries like geographic or subject-matter scope, not the appellate review role.
