All the King's actions have to undergo the refrendo procedure. Through the refrendo, the responsibility of the King is transported to other persons, who will be responsible for the King's actions, if such responsibility is demanded from them. Article 64 explains the refrendo, which transports the King's responsibility unto the Prime Minister for most cases, though it also establishes the refrendo for Ministers in some cases. In general, when there is not a formed government, the responsibility is assumed by the President of the Congress of Deputies. Without the refrendo, the King's actions are null and void.
