As in England, the medieval unitary
king's council evolved into distinct bodies, the smallest being the privy council, of senior advisors to the king (or, in Ireland's case, to the king's representative). Others were the
great council, which evolved into the
Parliament of Ireland, and the
afforced council, an ad-hoc body of intermediate size.
Charles I ordered the Lord Deputy to reform the "negligent meeting" of the privy council's committees. This power was controversially used in Dublin in 1711–1714 to keep out
Whigs, and in Cork in 1835 to keep out an
Orangeman.
Poynings' Law (1495) gave the Irish Privy Council a leading role in the legislative process. Before the council summoned each new Parliament (with a
general election to the
Commons) it had to submit the Parliament's
bills to the
Privy Council of England for approval as "causes and considerations" for the summons. Initially, all bills were by the Irish council, and the Commons and
Lords could pass or reject, but not amend them. By the 18th century, a
legal fiction arose where Parliament debated "heads of a bill" and petitioned the council to introduce it; the council could still amend or reject these "heads".
Private bills were always initiated by the council until the
Williamite revolution. The council gradually stopped initiating any bills beyond two "causes and considerations" bills, one of which was always a
money bill, to which the Commons objected as violating its
control of supply. The
Patriot Party defeated the 1768 "Privy Council Money Bill", heralding an increase in
parliamentary sovereignty which culminated in the
Constitution of 1782, which removed the Irish Privy Council from the legislative process. (The British Privy Council retained the right to veto Irish bills, but not to amend them.)
Orders in Council were issued by the chief governor with the
advice and consent of the Privy Council. From
Elizabeth to Charles I, the Irish council filled the legislative gap during long intervals between Irish parliaments by passing "Acts of State", justified on grounds similar to those latterly used for Charles'
Personal Rule. The governor could issue
proclamations without the council on routine matters, but on important policy questions needed the council's agreement. The 1724 defeat of
Wood's halfpence came after the Irish privy council sided with the Irish parliament in opposition to the British government and refused to intercede between parliament and the Lord Lieutenant,
Lord Carteret. The Irish council developed a judicial role later than the
Privy Council of England, with the
Court of Castle Chamber sitting in Dublin Castle from 1571 to 1641. Privy Councillors had a right of
audience with the viceroy, and many men were anxious to become members purely for this access and took little or no part in council business.
Charles II's 1679 plan to reduce the number to 20 or 30 was not acted on. By the eighteenth century, there were over 100 councillors, few of whom usually attended meetings. Nevertheless, the viceroy informally consulted an inner circle before the formal council meetings, in order to expedite decision-making. Although the
Acts of Union 1800 abolished the Kingdom of Ireland and its parliament, its Privy Council (like the Lord Lieutenant) was retained, alternatives —abolishing the Irish council or merging it with the British one— receiving little consideration. In 1801
Lord Pelham, a former
Chief Secretary for Ireland, became British
Home Secretary and assumed that his office now extended to Ireland, but viceroy
Philip Yorke, 3rd Earl of Hardwicke insisted that the silence of the 1800 acts regarding the Irish council implied that its assent remained obligatory for effecting government orders.
Ireland under the Union had some government bodies answerable to the viceroy and Council and others which were divisions of
Whitehall departments; however, a lack of collegiality prevented the Irish council becoming a rival power centre. In 1852 the Privy Council Office was merged into the Chief Secretary's Office. Latterly the council's executive role was merely formal and ceremonial. Of ten meetings held from August 1886 to January 1887, attendance ranged from four (including three Lords Justices) to ten (including the Lord Lieutenant). There was controversy over the proclamations issued by the council under the
Criminal Law and Procedure (Ireland) Act 1887, since among the signatories were senior judges who might hear appeals against sentences handed down under the act. Other committees heard appeals under the
Tramways and Public Companies (Ireland) Act 1883, Educational Endowments (Ireland) Act 1885, Labourers (Ireland) Act 1885, and Irish Education Acts 1892 and 1893. The Veterinary Department of the Irish Privy Council, established 1866–72, was "most peculiarly constituted", having no corresponding committee of the council; it became the Veterinary Branch of the
Department of Agriculture and Technical Instruction upon the latter's 1900 establishment. The Privy Council's Irish Universities Committee was established in 1908 to hear petitions relating to the
National University of Ireland (NUI) and
Queen's University Belfast (QUB). ==Supersession==
