The Taoiseach has poured cold water on the idea of a border poll by 2030, but the debate about when — and how — such a vote might happen isn’t going away. In the early flurry of commentary on the presidential election, some even suggested it could fall within the term of the next occupant of Áras an Uachtaráin. Yet the truth is murkier: few people know the rules, and the Good Friday Agreement’s language is vaguer than many assume. 

So, who decides when the moment is right? What does “appears likely” really mean in law? And how much power rests with Westminster to stop or stall the process? In fact, as Sam McBride from the Belfast Telegraph recently highlighted, the Westminster parliament in London may still hold the final legislative key — something that even seasoned commentators have overlooked. 

On today’s podcast, Ciara Doherty speaks to Dr Jennifer Kavanagh, law lecturer at South East Technological University, about the Taoiseach’s remarks, the legal grey zones of the Northern Ireland Act, and why the debate is as much about politics and the vagaries of opinion polls as it is about law.
