Twenty-eighth Amendment of The Constitution Bill 2008 (Ireland) - Background

Background

See also: Irish European Constitution referendum

A 1987 decision of the Supreme Court established that ratification by Ireland of any significant amendment to the Treaties of the European Union requires an amendment to the Constitution of Ireland. All Constitutional amendments require approval by referendum.

A referendum on the Treaty establishing a Constitution for Europe of the European Union was expected to be held in 2005 or 2006 but was cancelled following the rejection of the Constitution by voters in France in May 2005 and in the Netherlands in June 2005. The Treaty of Lisbon represents the European-wide political compromise that was agreed upon in the wake of the rejection of the Constitution. It preserves most of the content of the Constitution, especially the new rules on the functioning of the European Institutions, but gives up any symbolic or terminologic reference to a Constitution. (See Treaty of Lisbon compared to the European Constitution.)

Ireland is the only EU member state that has held a public referendum on the Treaty. Ratification of the Treaty in all other member states is decided upon by the states' national parliaments. The referendum is part of the larger EU ratification of the Treaty, which requires that all EU members, and the European Parliament must ratify it. A "No" vote in the referendum could block the treaty in the EU altogether. However, the Treaty of Nice was ratified by Ireland in 2002 in a second referendum after the first vote rejected it by a narrow margin in 2001.
