Before the Act of Union 1800, any bill passed by the Parliament of Ireland and approved by the Privy Council of Ireland was sent to London under the Great Seal of Ireland and, if approved by the Privy Council of England (later the Privy Council of Great Britain), was returned under the Great Seal of the Realm to be enacted.Gilbert 1865, pp.455–6 This procedure was required both under Poynings' Law (1495) and under the Constitution of 1782 which amended it. Parliament was summoned under the Great Seal of England rather than that of Ireland, even after 1782.
