The Declaratory Act 1719, which had given Great Britain the right to legislate for Ireland and had denied the appellate jurisdiction of the Irish House of Lords, is repealed on June 21, 1782.

An Act for the better securing the dependency of the Kingdom of Ireland on the Crown of Great Britain (long title) is an Act passed by the Parliament of Great Britain which declares that it has the right to pass laws for the Kingdom of Ireland, and that the British House of Lords has appellate jurisdiction for Irish court cases. It becomes known as the Declaratory Act, and opponents in the Irish Patriot Party refer to it as the Sixth of George I, from the regnal year it is passed. Legal and political historians have also called it the Dependency of Ireland on Great Britain Act 1719 or the Irish Parliament Act, 1719. Prompted by a routine Irish lawsuit, it is aimed at resolving the long-running dispute between the British and the Irish House of Lords as to which is the final court of appeal from the Irish Courts. Along with Poynings’ Law, the Declaratory Act becomes a symbol of the subservience of the Parliament of Ireland, and its repeal is long an aim of Irish statesmen, which is finally achieved for Anglican Irish as part of the Constitution of 1782.

In 1709, the Irish Court of Exchequer hears a lawsuit between Maurice Annesley and his cousin Hester Sherlock over which of them have the right to possession of certain lands at Naas, County Kildare. The court finds in Annesley’s favour. Mrs. Sherlock appeals to the Irish House of Lords which upholds her appeal. Annesley then invokes the long-disputed jurisdiction of the British House of Lords to hear appeals from the Irish courts, and that house pronounces in his favour. The Court of Exchequer duly complies with the decree of the British House, but Mrs. Sherlock appeals again to the Irish house, which orders the Barons of the Exchequer to comply with its own decree and, when they refuse, imprison them for contempt of Court. The political uproar is out of all proportion to the importance of the lawsuit itself.

The bill has its second reading in the Commons on March 4, 1719, where it is chiefly opposed on the grounds that it appears to have no purpose beyond increasing the power of the House of Lords. Other objections include an argument that the preamble and the enacting section of the bill are contradictory, and that Ireland has historically had an independent judiciary. It is supported by Joseph Jekyll and Philip Yorke, and carries 140 votes to 83. It is then passed on March 26, 1719.

Section I of the Act notes that the Irish House of Lords had recently “assumed to themselves a Power and Jurisdiction to examine, correct and amend” judgements of the Irish courts, which it holds to be illegal. As such, it declares that the Kingdom of Ireland is subordinate to and dependent upon the British crown, and that the King, with the advice and consent of the Parliament of Great Britain, has “full power and authority to make laws and statutes of sufficient validity to bind the Kingdom and people of Ireland.” Section II declares that the House of Lords of Ireland has no jurisdiction to judge, affirm or reverse any judgement, sentence or decree made in any court within the Kingdom of Ireland, and that all proceedings before the House upon any such matter are declared to be null and void to all intents and purposes whatsoever.

The Irish House of Lords is understandably infuriated by the curtailment of its powers, and the Barons of the Exchequer, though they are soon released from custody, are subject to intense vilification. While many people think that the Irish House of Lords had brought about the crisis by its own high-handed behaviour, the “Sixth of George I” remains a source of grievance for decades.

The Declaratory Act 1719 provides a model for the American Colonies Act 1766, which is also known as the “Declaratory Act” and is a similar source of grievance in the Thirteen Colonies. The British defeat in the subsequent American Revolutionary War prompts a more conciliatory tone towards Ireland, and the Declaratory Act 1719 is repealed in its entirety when the Repeal of Act for Securing Dependence of Ireland Act 1782 receives royal assent on June 21, 1782.
