The Court of Appeal decides on the appeal. It may review the contested decision on grounds other than those raised by the appellant in the appeal. The decision of the Court of Appeal is in principle no longer open to defense. Only in exceptional cases may an extraordinary appeal be brought against a decision of the Court of Appeal.

The Court of Appeal shall review the correctness of the decision of the Court of First Instance to the extent that it is set out in the notice of appeal. However, it may go beyond the scope of the appeal and may or must take account of selected facts even without an application. As a result, it may review the decision both on the facts and on the law, including whether all the procedural rules have been duly observed.

Otherwise, it may set aside the decision of the Court of First Instance and refer the case back to it for a fresh hearing or, alternatively, the Court of Appeal itself may decide the case. If the Court of Appeal finds that the proceedings of the Court of First Instance were not vitiated, it shall uphold its decision. Otherwise, it may set aside the decision of the Court of First Instance and refer the case back to it for a fresh hearing or, alternatively, the Court of Appeal may itself decide the case.

Once the decision of the Court of Appeal has been notified to the parties, it becomes final and binding on the parties. No (further) appeal can be lodged against the decision of the Court of Appeal. The only possible defense is one of the so-called extraordinary remedies.
