Eighteenth Amendment of the Constitution of Ireland
The Eighteenth Amendment of the Constitution Act 1998 is an amendment of the Constitution of Ireland which permitted the state to ratify the Treaty of Amsterdam. It was approved by referendum on 22 May 1998 and signed into law on the 3 June of the same year. The referendum was held on the same day as the referendum on the Nineteenth Amendment, which related to approval of the Good Friday Agreement.
Background
The Amsterdam Treaty was signed on 2 October 1997 by the member states of the European Union, amending provisions of the Maastricht Treaty and the Rome Treaty. Following the Supreme Court decision of Crotty v. An Taoiseach, a constitutional amendment was required before the state could ratify the Treaty. The Treaty of Amsterdam contained a number of optional protocols that member-states could activate at a later time after its adoption. The Eighteenth Amendment permitted the Republic to choose to exercise these options, provided it had the support of the Oireachtas.Changes to the text
