Members who hold their position by virtue of an office they occupy
The Law Lords
The Lord Chancellor, the Lord President of the Supreme Court and the Attorney General are automatically members of the Privy Council. The constitution doesn't set a limit on the number of members who sit on the Council and this is left to the discretion of the Monarch.
Judicial functions
The King in Privy Council has the authority to make appointments to most posts in the judicial branch of government. One of the primary goals of the constitutional reforms of 2010 was to ensure the separation of the executive, legislative and judicial branches of government. A significant result of these reforms and constitutional amendments was the removal of the King from the executive power. Executive power was transferred to the cabinet. The drafters of the 2010 constitutional amendments did not want the executive government to control or interfere in the exercise of Judicial power. They chose to vest the power to make these appointment in the office of the constitutional and non-partisan head of state. These include:
The Council also contains a Judicial Committee, composed of the Lord Chancellor, The Attorney General, the Lord Chief Justice and five Law Lords, and called the Judicial Appointments and Discipline Panel. The Judicial Committee advise the King on the exercise of his judicial powers" and "investigate complaints against judges". The King in Privy Council is the final court of appeal for cases dealing with hereditary estates and titles.
Legislative functions
The Privy Council is empowered to issue orders in council to regulate the internal functions and operations of the council. Outside of these regulations the council has no legislative power in accordance with the democratic reforms of the constitution in 2010.
