Irish constitutional referendum, 1937 The Constitution of Ireland plebiscite, also known as the Plebiscite on the Draft Constitution, was a plebiscite held in the Irish Free State to approve the adoption of a new constitution for the country. The vote was held on 1 July 1937, the same day as the general election. It was passed by a plurality, with 56% of voters in favour, comprising 38.6% of the whole electorate. As a result, the current Constitution of Ireland came into effect on 29 December 1937, ending the Irish Free State. It was the only plebiscite to take place in the Irish Free State. It was also the only referendum that was officially called a plebiscite in the history of the country; all subsequent votes of this nature have taken place under the provisions of the current Irish constitution and are referred to as referendums.
