I thank Professor O'Mahony. It is great to have him before the committee again. There is always a great level of clarity when he appears before the committee and I welcome that.

I am grappling with all these legal issues, so forgive me. As unknown donors can become known donors through DNA, it is important to sever those rights. Where do we sever those rights? There is a dispute in the issues paper regarding the retrospective recognition for children, saying one cannot remove parentage retrospectively. Will Professor O'Mahony elaborate on that point?
