Dr. Laura Cahillane:

It is a difficult one. As Professor Mullally has already stated, one would hope that, given that the courts have an obligation to interpret Irish law in harmony with the European Convention on Human Rights, the courts would give an up to date reading of article 41. This would require them, however, to in many ways reverse what has gone before. It would be quite a big decision for the courts to decide to change the definition of marriage: it would have to be a Supreme Court decision. It is possible, of course, but it might be more effectively undertaken by a referendum.
