7 Section 20. Subject to section 21, the succession to the Throne shall be in accordance with the Palace Law on Succession, B.E. 2467 (1924). The Amendment to the Palace Law on Succession, B.E. 2467 (1924) shall specifically be the Royal Prerogative of the King. At the initiative of the King, the Privy Council shall prepare the draft Palace Law Amendment to the existing Palace Law and shall present it to the King for His consideration. When the King has already approved the draft Palace Law Amendment and bestowed His signature thereon, the President of the Privy Council shall notify the President of the National Assembly who shall inform the National Assembly. The President of the National Assembly shall countersign the Royal Command. The Palace Law Amendment shall have force of law upon its publication in the Government Gazette. Section 21. In the case where the Throne becomes vacant and the King has already appointed an Heir to the Throne under the Palace Law on Succession, B.E. 2467 (1924), the Council of Ministers shall notify the President of the National Assembly. The President of the National Assembly shall convoke the National Assembly for acknowledgement thereof, and shall invite such Heir to ascend the Throne and proclaim such Heir as King. In the case where the Throne becomes vacant and the King has not appointed an Heir under paragraph one, the Privy Council shall submit the name of the Successor to the Throne under section 20 to the Council of Ministers for further submission to the National Assembly for approval. In this regard, the name of a Princess may be submitted. Upon the approval of the National Assembly, the President of the National Assembly shall invite such Successor to ascend the Throne and proclaim such Successor as King. Section 22. Pending the proclamation of the name of the Heir or the Successor to the Throne under section 21, the President of the Privy Council shall be Regent pro tempore. However, if the Throne becomes vacant while the Regent has been appointed under section 16 or section 17 or while the President of the Privy Council is the Regent under section 18 paragraph one, such Regent, as the case may be, shall continue to be the Regent until the proclamation of the name of the Heir or the Successor to ascend the Throne as King. In the case where the Regent who has been appointed and continues to be the Regent under paragraph one is unable to perform his or her duties, the President of the Privy Council shall act as Regent pro tempore.
