The Twenty-sixth Amendment of the Constitution Act 2002 (previously bill no. 32 of 2003) is an amendment of the Constitution of Ireland which permitted the state to ratify the Treaty of Nice. It was approved by referendum on 19 October 2002 (sometimes known as the second Nice referendum) and signed into law on 7 November of the same year. The amendment followed a previous failed attempt to approve the Nice Treaty which was rejected in the first Nice referendum held in 2001.
