According to the Act of Foundation dated 15 February 1992, the advisory bodies of the Crown are: the Privy Council, the Crown Council and the Crown Cabinet (formed later).
The Privy Council is a Council inner body, with up to 10 members (not counting the members of the Royal Family appointed by the Crown), who are nominated by the Crown for an indefinite period of time. The Privy Council deals in everyday duties of the Crown.
The Crown Council is a larger body, with up to 30 members, who are appointed by the Crown to a life-long mandate. This body deals with strategic matters of paramount importance for the people, state and the Crown. The members of the Council are appointed by the Crown from the list of candidates prepared by the Council members themselves. The Crown can, if need be, make the appointment “in pectore”, meaning that the appointment is to be made in discretion and is known to only the Crown and the person appointed in that way. Exceptionally, the Crown can call for a conference of all its counselling bodies, which are then transformed into the Crown Assembly.
The Crown presides over all the Crown bodies, names the Chancellor for coordination purposes or delegates the duties of a Chancellor to a Privy Council member. The power of the Crown is manifested in the person of the Head of the Royal Family.
Members of the Privy Council are HRH Hereditary Prince Peter, HRH Prince Philip, HRH Prince Alexander, Arch. Dragomir Acovic, Mr. Djurdje Ninkovic, The Hon. Branko Terzic and Mr. Dusan Babac.
