The Eighth Amendment of the Constitution Act 1983 was an amendment to the Constitution of Ireland which inserted a subsection recognising the equal right to life of the pregnant woman and the unborn. Abortion had been subject to criminal penalty in Ireland since 1861; the amendment ensured that legislation or judicial interpretation would be restricted to allowing abortion in circumstances where the life of a pregnant woman was at risk. It was approved by referendum on 7 September 1983 and signed into law on 7 October 1983.
