The Twelfth Amendment was a failed proposal to amend the Constitution of Ireland, to state that the risk of suicide should not be considered a sufficient reason to legally allow an abortion. It was rejected in the 1992 referendum on abortion and the risk of suicide.

The full title of the proposal was the Twelfth Amendment of the Constitution Bill, 1992. On the same day the "Thirteenth" and "Fourteenth Amendments" were approved. As these could not be renamed the number twelve has simply been 'skipped'. There has therefore officially been no successfully enacted "Twelfth Amendment" of the Irish constitution.

Proposed changes to the textEdit

  • Proposed insertion of additional text to Article 40.3.3:
It shall be unlawful to terminate the life of an unborn unless such termination is necessary to save the life, as distinct from the health, of the mother where there is an illness or disorder of the mother giving rise to a real and substantial risk to her life, not being a risk of self-destruction.
  • The rejection of the Twelfth Amendment, together with approval of the Thirteenth Amendment and the Fourteenth Amendment made the full text of the constitution in regard to abortion (40.3.3) the following:
The State acknowledges the right to life of the unborn and, with due regard to the equal right to life of the mother, guarantees in its laws to respect, and, as far as practicable, by its laws to defend and vindicate that right.
This subsection shall not limit freedom to travel between the State and another state.
This subsection shall not limit freedom to obtain or make available, in the State, subject to such conditions as may be laid down by law, information relating to services lawfully available in another state.


The referendum in November 1992 was largely in response to Attorney General v. X (more commonly known as the "X case") - a case that arose where a 14-year-old girl who had become pregnant from rape was threatened with legal action for travelling to the England to obtain an abortion. It proposed that the possibility of suicide was not a sufficient threat to justify an abortion. The proposal was put to a referendum on 25 November 1992 but was rejected.

On the same day, the Thirteenth Amendment and Fourteenth Amendment were submitted to and approved by referendum. The former guaranteed freedom of travel with respect to abortion, and the latter, freedom of speech with respect to the same issue.

In 2002 a second failed attempt was made to rule out the risk of suicide as grounds for an abortion. This was the proposed Twenty-fifth Amendment, which was also rejected in a referendum, in March that year, but by a much narrower margin.
