A decision or precedent made by which of the following types of court applies to all other courts under its jurisdiction?

a. magistrate

b. trial

c. appellate

d. commissioners

Trial?

The correct answer is c. appellate.

An appellate court is a type of court that reviews decisions made by lower courts, such as trial courts. When an appellate court makes a decision or establishes a precedent, it applies to all other courts under its jurisdiction. This means that lower courts within the same jurisdiction must follow the decision or precedent set by the appellate court.

To arrive at this answer, one can understand the hierarchy of courts. In a typical legal system, trial courts are the initial level where cases are heard and decided. If a party is unsatisfied with the decision made by a trial court, they can appeal to a higher court, which is usually an appellate court. The appellate court reviews the lower court's decision, assesses legal issues, and determines whether the lower court made any errors in applying the law. The decision made by the appellate court sets a precedent that binds all other courts within its jurisdiction, including trial courts, magistrate courts, and commissioners.
