The decisions of an administrative court are normally made by a composition of three members. Members of the court are the Chief Judge and Administrative Judges. In certain matters, such as those involving mental illness or the taking of children into care, also an expert member participates in the hearing and decision of the matter. Matters in accordance with the Environmental Protection Act and the Water Act are considered in a composition consisting of legally trained members as well as experts in either natural sciences or engineering.
Administrative courts may decide certain simple appeals in a comprised composition, if this does not risk the legal protection of the part.
Certain appeals, listed in law, may be decided in a composition of two members, when the issue is clear and does not require new interpretation of the law. This includes certain appeals relating to income, real estate and car taxes and building permits. If the members in a composition of two members disagree on the decision the issue will be decided by a normal composition of three members.
One member may decide among other things appeals relating to parking tickets, charges for towed vehicles, driving licences and public transport penalty fees. One member may also make decisions on all provisional prohibitions on enforcement and prohibit or stay the enforcement of taxes or payments.
