Poynings' Law or the Statute of Drogheda (10 Hen.7 c.4 [The Irish Statutes numbering] or 10 Hen.7 c.9 [Analecta Hibernica numbering]; later titled "An Act that no Parliament be holden in this Land until the Acts be certified into England") was a 1494 Act of the Parliament of Ireland which provided that the parliament could not meet until its proposed legislation had been approved both by Ireland's Lord Deputy and Privy Council and by England's monarch and Privy Council. It was a major grievance in 18th-century Ireland, was amended by the Constitution of 1782, rendered moot by the Acts of Union 1800, and repealed by the Statute Law Revision (Ireland) Act 1878.
