Twenty-seventh Amendment of the Constitution of Ireland

Insertion of new Article 9.2:

1º Notwithstanding any other provision of this Constitution, a person born in the island of Ireland, which includes its islands and seas, who does not have, at the time of the birth of that person, at least one parent who is an Irish citizen or entitled to be an Irish citizen is not entitled to Irish citizenship or nationality, unless provided for by law.

2º This section shall not apply to persons born before the date of the enactment of this section

Previous Article 9.2 renumbered as Article 9.3.

Prior to 1999 the right to citizenship by reason of birth in Ireland existed in ordinary legislation. The only people who had a constitutional right to citizenship were those who were citizens of the Irish Free State when the constitution came into force.[4] For those born after 1937 the Constitution stated that the "future acquisition and loss of Irish nationality and citizenship shall be determined in accordance with law".[5] This changed in 1999 when as part of the Nineteenth Amendment the following clause was inserted into Article 2 of the Constitution:

It is the entitlement and birthright of every person born in the island of Ireland, which includes its islands and seas, to be part of the Irish Nation. That is also the entitlement of all persons otherwise qualified in accordance with law to be citizens of Ireland.

This provision was intended to ensure that people from Northern Ireland would not be deprived of Irish citizenship, but also created a constitutional right to citizenship by birth.[4] Though immigration concerns did not feature much as an issue in the referendum campaign for the Nineteenth Amendment, it was given as an argument against in the Referendum Commission's leaflet:

"The new Article 2 will give a constitutional right of citizenship to anyone born in Ireland. This will make it very difficult to change the laws on citizenship and it may prevent the enactment of necessary laws to regulate immigration."

By 2002 , it was reported that the number of Births in Ireland's national maternity hospital had reached a 20 year high with 8,162 births , 15% of which were reported as being births to Non nationals.[6]

The Minister for Justice at the time Michael McDowell said that between 40% and 50% of non-EU nationals who give birth in Ireland were doing so to gain Irish citizenship for their children [7]

In April 2004 , An internal Department of Justice memo revealed that in August 2003 , the Masters of Ireland's maternity hospitals had warned that pregnant women were arriving in Ireland from abroad with their "antenatal notes".[8]

In October 2004 , a European Court of Justice ruling (Case C-200/02) Man Chen ruled that the Non EU Parent of a Child who is a citizen of the Union had a right to reside with that child anywhere in the EU .[9] The case involved a Chinese Woman, Man Lavette Chen who entered the United Kingdom in May 2000 when she was about six months pregnant. She travelled to Belfast in July of that year from Wales .. "to create a situation in which the child she was expecting would be able to acquire the nationality of another Member State in order thereafter to secure for her child and for herself a long-term right to reside in the United Kingdom".[9] The Court ruling meant that non EU nationals giving birth to a child in Ireland could gain EU residency rights .

The Twenty-seventh amendment was introduced by the Fianna Fáil–Progressive Democrats coalition government of Bertie Ahern. It was also supported by Fine Gael (the largest opposition party) but they refused to campaign due to what they complained was insufficient consultation before the poll. The amendment was opposed by the Labour Party,[10] the Green Party,[10] Sinn Féin,[10] and the Socialist Party, as well as the Irish Human Rights Commission, a statutory body, and the Irish Council for Civil Liberties, a civil society non-profit organisation.[10] It was also opposed by Northern Ireland's SDLP, as Irish citizenship is an option for people born there.

The government presented the amendment as a common sense proposal that would close a constitutional loop-hole and allow Irish law to be brought into line with the rest of Europe.[11] In 2004, no other nation of the European Union granted citizenship by birth in the same manner as Ireland. However, citizenship by birth still exists in some non-European nations such as Canada and the United States.

Some criticisms of the amendment related merely to the manner in which it was proposed. In the lead-up to the referendum the Irish and British governments issued a joint statement saying that they did not regard the proposed constitutional change as affecting the British-Irish Agreement[12] (this being the inter-governmental component of the Good Friday Agreement). The Democratic Unionist Party cited the amendment as evidence that the Agreement could be changed.[13]

The referendum on the amendment was held on the same day as both European and local elections .

In the referendum, the amendment was ultimately approved, by a large majority of almost 80% in favour.

Although most Irish referendums count votes per Dáil constituency, this one was organised by city/county council area, the basis for the local elections being held simultaneously. Voters received different-coloured ballot papers for the referendum, city/county council election, and European Parliament election; all went into the same ballot box and were separated by colour once the boxes arrived at the count centre for the city/county.[15] Not all voters received all ballots as the franchises differ.

The amendment was signed into law on 24 June 2004, after the referendum result had been certified by the High Court. On 29 September the government published a bill to amend nationality law within the scope of the revised constitutional parameters.[16][17] This bill was signed into law on 15 December 2004 as the Irish Nationality and Citizenship Act 2004.[18]

In December 2004 , The Master of Ireland's National Maternity Hospital Dr Declan Keane told irishhealth.com that prior to the referendum, 16% of the deliveries at the hospital were to non-EU women and five per cent were to women from other EU countries. He said that since the referendum, this figure had been reversed, with 16% of births now accounted for by mothers from other EU countries and five per cent to mothers from outside the EU. [19]
