With regard to the Catholic University of Louvain, in response to Senator Hanafin and others, if I created the impression that I was quoting it as an authority of the Catholic Church, I apologise for that. That was certainly not my intention. I simply quoted what was said there to explain the difficult ethical complexities which arise in this whole area, which I believe it spelled out extremely well. I have not got the precise source within the relevant faculty, but I have no doubt that reference can be readily obtained after this debate.
