Editing Treaty of Nice (section)

===Second referendum===
{{Main|Twenty-sixth Amendment of the Constitution of Ireland}}
The Irish government, having obtained the [[Seville Declarations on the Treaty of Nice|Seville Declaration]] on Ireland's policy of military neutrality from the European Council, decided to have [[Twenty-sixth Amendment of the Constitution of Ireland|another referendum on the Treaty of Nice]] on Saturday, 19 October 2002. Two significant qualifications were included in the second proposed amendment, one requiring the consent of the [[Dáil]] for [[Enhanced co-operation|enhanced cooperation]] under the treaty, and another preventing Ireland from joining any EU common defence policy. A 'Yes' vote was urged by a massive campaign by the main parties and by civil society and the social partners, including campaigning through canvassing and all forms of media by respected [[pro-European]] figures like then [[European Parliament|EP]] president [[Pat Cox]], former [[Czech Republic|Czech]] president [[Václav Havel]], former [[President of Ireland]] [[Patrick Hillery]] and former [[Taoiseach]] (prime minister) [[Garret FitzGerald|Dr. Garret FitzGerald]]. Prominent civil society campaigns on the Yes side included [[Fianna Fáil]], [[Fine Gael]], the [[Labour Party (Ireland)|Labour Party]], the [[Progressive Democrats]], the [[Irish Alliance for Europe]] led by Professor Brigid Laffan and Adrian Langan, and [[Ireland for Europe]] led by Ciarán Toland. On the No Side, the principal campaigns were those of the [[Green Party (Ireland)|Green Party]], [[Sinn Féin]], [[Anthony Coughlan]]'s [[National Platform]], [[Justin Barrett]]'s No to Nice campaign, and [[Roger Cole]]'s [[Peace and Neutrality Alliance]]. The result was a 60% "Yes" vote on a near-50% turn-out.

By then all other EU member states had ratified the Treaty. Ratification by all parties was required by the end of the year, or else the Treaty would have expired.
