Norway uses a civil law system where laws are created and amended in Parliament and the system regulated through the Courts of justice of Norway. It consists of the Supreme Court of 20 permanent judges and a Chief Justice, appellate courts, city and district courts, and conciliation councils. The judiciary is independent of executive and legislative branches. While the Prime Minister nominates Supreme Court Justices for office, their nomination must be approved by Parliament and formally confirmed by the Monarch in the Council of State. Usually, judges attached to regular courts are formally appointed by the Monarch on the advice of the Prime Minister.
