The Constitution is the fundamental legal document in Ireland, which sets out the basic rights and rules for everyone in the country - but how much do you know about it? Have you ever even read it? This documentary explains three different aspects of how the constitution works, with three constitutional experts. Ellen O’Regan speaks to abortion and marriage equality campaigner Ailbhe Smyth about the road to a referendum, practising barrister Nóra Ní Loinsigh about how you actually go about defending your constitutional rights in court, and Professor Conor O’Mahony about the special kind of constitutional rights we all have, but that aren’t written down anywhere.
