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 the grading of comprehensive school pupils, the decision of the administrative court is final and cannot be appealed to the Supreme Administrative Court.
In administrative matters, the Supreme Administrative Court has the sole power to grant ertraordinary means of appeals, which are the annulment of a decision, a complaint against it, or an extension of the already lapsed time of appeal.
The Council of State, i.e. the Finnish government, acts in some cases as an administrative authority. The decisions it makes in this competence can be appealed against on the grounds of legality of the decision.
As in all Finnish administrative courts, the legal costs of both parties in the Supreme Administrative Court are born, unless it is reasonable to award the prevailing party all or part of the costs. Nonetheless, when the authority prevails against a private claimant, it must bear all its costs, unless the private party has made a frivolous claim.
