The United Chambers also have to provide for the regency in two other cases, in accordance with Articles 92 and 93: in the event that the successor to the throne is a minor or in the event that the King is unable to reign. In both cases, the United Chambers also have to make provisions regarding the guardianship. Article 94 stipulates that the regency can only be conferred on one person and that the Regent can only enter into office after taking the same constitutional oath that the King must take before he can accede to the throne. Article 93 also stipulates that the ministers must establish the inability to reign and subsequently convene the Chambers of the Federal Parliament.
