Article 115
In order to safeguard international peace and security or to promote the international rule of law and cooperation, the Storting may, by a three-fourths majority, consent that an international organisation to which Norway belongs or will belong shall have the right, within specified fields, to exercise powers which in accordance with this Constitution are normally vested in the authorities of the State, although not the power to alter this Constitution. For the Storting to grant such consent, at least two thirds of its Members shall be present, as required for proceedings for amending the Constitution.
