The Elverum Authorization (Norwegian: Elverumsfullmakta) allowed the Cabinet of Norway to temporarily and legitimately assert absolute authority given that the Storting (the Norwegian parliament) was no longer able to convene in ordinary session in Oslo because of the German invasion of Norway.
The action was approved unanimously by the Storting in the town of Elverum on 9 April 1940, after the Norwegian royal family, the Cabinet, and the Storting had evacuated Oslo to evade capture by German troops in the course of Operation Weserübung during World War II.
The authorization is controversial in that it constituted a complete abandonment of the legislative powers in Norway during the war.
[citation needed] The issue was brought to the Supreme Court of Norway, which ruled that the authorization was legitimate and valid.
[citation needed] Germany demanded the king to appoint Vidkun Quisling as prime minister.
