Against a judgment or an order of the administrative courts, an appeal for unlawfulness can be made to the Supreme Administrative Court. However, the appeal is only admissible if it depends on the solution of a legal question that is of fundamental importance. This is the case when:
- the judgment of the administrative court deviates from the case law of the Supreme Administrative Court
- such case law is lacking, or
- the legal question to be resolved is not uniformly answered by the previous case law of the Supreme Administrative Court
The appeal must be submitted to the competent administrative court within six weeks of service of the decision. It should be noted that legal representation is required for proceedings before the Supreme Administrative Court.
