Where do the witnesses think the legislation functions best in other countries, where is the best structure in place? Have they identified a country we could learn lessons from? In other countries there is legislation but here in Ireland we have to consider the constitutional issues. Are there any constitutional issues that we need to be concerned about and to flag up at this stage in order that they do not arise in five years' time when someone suddenly takes a constitutional challenge? It is a very complex legal area because so many different parties are involved. It is important to get it right. It is not possible to always get legislation 100% right but let us at least make every effort to do that.
