A project examining how any future referendum on the constitutional status of Northern Ireland would be best designed and conducted.
The Working Group on Unification Referendums on the Island of Ireland was established in 2019 to examine how any future referendums on the constitutional status of Northern Ireland would best be designed and conducted. It published its Final Report on 26 May 2021. The report explores each aspect of the process, including, for example, how decisions would be made on whether to call a referendum, whether referendums would best happen before or after detailed plans for the form of a united Ireland had been developed, how referendum campaigns would be regulated, and who would be able to vote. It takes no view on whether such referendums should takes place.
Reactions to the project
it's [the report] a model of cool lucidity, in an area that is so fraught with heated political rhetoric on all sides. So anyone interested in the future of these islands, I would urge them to read the full report...because it's such a valuable contribution to the debate" - Rory Carroll, Ireland correspondent for the Guardian
One of the most important academic interventions in policy debate in Ireland in recent decades". - Professor John Coakley, Queen's University Belfast and University College Dublin
The academic title obscures the fact that it’s the most significant contribution to the constitutional debate in decades". - Sarah Creighton, commentator and writer
Your Working Group on unification referendums have at least told people the questions that need to be addressed and to be answered. If we’re sleepwalking towards this you at least have been attempting to wake us up". - Former Conservative Minister Michael Portillo, speaking on his Times Radio show on 4 December
A shining example of how carefully-crafted and public-spirited research can help us learn lessons from the past, and inform public debate without foreclosing it". - Tweet by Associate Professor Tom Gerald Daly, University of Melbourne
About the Working Group
The Constitution Unit teamed up with eminent scholars in Northern Ireland, Ireland, and the United States to examine how any future referendums on the constitutional status of Northern Ireland would best be designed and conducted. The project did not look at, or take a view on, whether such votes would be desirable or what the outcome should be if referendums were to be held.
The project was made possible by generous funding from the British Academy under its Humanities and Social Sciences Tackling the UK’s International Challenges programme and from the Joseph Rowntree Charitable Trust. Comprising scholars with expertise in politics, law, sociology, and history, the Working Group consulted and deliberated in depth between late 2019 and early 2021. Its Final Report is now published. The members of the Working Group are listed below.

Public consultation working paper
An analysis of responses to a public consultation on sentiment in Northern Ireland towards the prospect of unification referendums on the island of Ireland, written by Alan Renwick, Nadia Dobrianska, Conor J. Kelly, and Charlotte Kincaid.
In preparation for the main project, the Unit published a background report in March 2019 that sought to stimulate discussion by outlining the key issues. Written by Unit Honorary Senior Research Associate and former civil servant Alan Whysall, this set out the current situation, including gaps and anomalies in the existing legal provision, and examined possible ways of addressing these deficiencies.

Some members of the Working Group are involved in the ARINS (Analysing and Researching Ireland North and South) project, which is conducting research on constitutional, institutional and policy options for Ireland, north and south, in a post-Brexit context. Some of the research produced by Working Group members under the ARINS project expands upon the research conducted by the Working Group. Find out more about the project and read related papers.
