In Norway, impeachment, also known as the Constitutional Court of the Realm (Norwegian: Riksrett), is a judicial process with the power to convict Members of Parliament, Members of the Council of State, and Supreme Court Justices for criminal acts performed in line of duty. Impeachment is based on the Constitution of Norway §§ 86 and 87. Parliament authorizes the impeachment process, which establishes a tribunal consisting of five members of the Supreme Court and six lay members appointed by the Parliament of Norway. Impeachment has been used eight times, the last case being held in 1927.
