The Supreme Administrative Court of Finland (Finnish: korkein hallinto-oikeus, Swedish: högsta förvaltningsdomstolen) is the highest court in the Finnish administrative court system, parallel to the Supreme Court of Finland. Its jurisdiction covers the legality of the decisions of government officials, and its decisions are final. Appeals are made to the Supreme Administrative Court from the decisions of the administrative courts of Helsinki, Turku, Hämeenlinna, Kouvola, Kuopio, Vaasa, Oulu, Rovaniemi and Åland, the Market Court, and the Council of State.
In most issues, it is possible to appeal to the Supreme Administrative Court of Finland from the judgment of the administrative court. However, in some case areas of administrative law, an appeal requires a leave of appeal from the Supreme Administrative Court. The most important such area are insurance cases. In some restricted areas of law, for example, in parking fines, the decision of the administrative court is final and cannot be appealed to the Supreme Administrative Court.
