throne may also pass to the child of the Queen who is pregnant at the time of the demise of the King if no lineal heir exists. Such is an example of semi-Salic law. If there are no present or prospective lineal heirs, title passes to the nearest collateral line of the descendants of the King in accordance with the principle of lineal descent, with preference being given for elder over the younger. Title may never pass to children incapable of exercising the Royal Prerogatives by reason of physical or mental infirmity, nor to anyone whose spouse is a person other than a natural born citizen of Bhutan. The successor to the Throne receives dar (a scarf that symbolizes the conferring of rank) from the Machhen (the holy relic) of Shabdrung Ngawang Namgyal at Punakha Dzong, and is crowned on the Golden Throne. Upon the ascension of the King to the Throne, the members of the royal family, the members of Parliament, and the holders of offices requiring appointment by the King must take an oath of allegiance to the King. Regency The Constitution provides a procedural framework for a Council of Regency. A Council of Regency is established when the King has temporarily relinquished, by Proclamation, the exercise of the Royal Prerogatives; or when it has been resolved by at least ¾ of the total number of members of Parliament in a joint sitting that the King is unable to exercise the Royal Prerogatives by reason of temporary physical or mental infirmity; or the King abdicates or dies and the successor to the throne has not attained the age 21. These provisions are effective until the royal heir presumptive reaches age 21 and becomes Regent by right. When the successor to the throne reaches age 21, or when the King resumes the exercise of the Royal Prerogatives, notice must be given by Proclamation. However, when the King regains the ability to exercise the Royal Prerogatives, notice is given to that effect by resolution of Parliament. The Council of Regency collectively exercises the Royal Prerogatives and the powers vested in the King. The Council of Regency is composed of 6 members: one senior member of the royal family nominated by the Privy Council (below), the Prime Minister, the Chief Justice of Bhutan, the Speaker, the Chairperson of the National Council, and the leader of the Opposition Party.
