administrative courts may conduct surveys, hold oral proceedings, hear witnesses, experts or involved parties, or receive opinions from other authorities. The decisions of the municipal governments (, ) can be appealed against by any member of the municipality, regardless whether the decision involves them. However, while the usual administrative court proceeding examines both the reasonableness and the legality of the decision, the municipal decision can only be overturned on the grounds of legality. In addition, a municipal decision may not be amended by the administrative courts, only overturned. However, in some areas of administration, the municipal government acts as an administrative authority, and its decisions can be appealed against in the normal manner. The legal costs in the administrative court system are borne by the parties. However, the prevailing party may be awarded the legal costs partly or in full, if it is deemed reasonable in the light of the decision. If the private party prevails, the most important point considered is whether the proceeding was due to an error of the authority. The authority which prevails against a private party is not awarded its legal costs unless the appeal was frivolous.

Judges work in three-judge panels in the regional administrative courts and in five-judge panels in the Supreme Administrative Court. In certain types of matters, part-time experts also participate in the proceedings of the Administrative Courts.
