As the Parliament amended the Constitution in 1938 to introduce four-year terms instead of three-year terms, the representatives elected in 1936 were still active in 1940. On 9 April that year, Norway was invaded and occupied by Germany as a part of World War II. With the German invasion, a radio broadcast coup d'état by Vidkun Quisling followed, and German diplomat Curt Bräuer was sent to Norway to demand the abdication of the Norwegian King Haakon VII and Nygaardsvold's Cabinet. This was initially refused, as the Parliament, meeting at Elverum on 9 April, issued the Elverum Authorization where it empowered the King and government to continue representing Norway. Norway and Germany was at war that time, and fighting continued for some months. However, when mainland Norway capitulated on 10 June 1940, new negotiations with Nazi Germany were opened, resulting in a request being submitted from the Presidium of the Parliament of Norway to the now-exiled King and government to abdicate. The case had been controversial, splitting the parliamentary group of the Labour Party. Olav Meisdalshagen agreed that the King should abdicate, as did the majority of the parliamentary group. When the King broadcast his refusal to abdicate via BBC Radio on 8 July 1940, this became famous as "The King's No".
