Appeal refers to applying a court decision to a higher court (or a higher authority) for review. Appeal in administrative justice is the application of an administrative court decision to the higher court (usually the Council of State or the high administrative court) for review. The appeal in administrative jurisdiction provides the right to object to administrative court decisions and thus ensures that decisions believed to be erroneous or unlawful are evaluated by the higher court.

Appeals are generally available under certain circumstances. For example, an appeal may need to be filed within a certain period of time, and the existence of certain legal reasons (error of law, procedural errors in judgment, errors in evidence, etc.) may need to be demonstrated, usually based on the justification of the decision.

In Turkey, the legal remedy of appeal in administrative jurisdiction is by applying to the Council of State. The Council of State is a higher court that examines the decisions made by administrative courts and evaluates their legality. Using the appeal against administrative court decisions enables the legality of the decision to be evaluated from a broader perspective. This contributes to the fair and auditable functioning of the administrative justice system.
