Professor Brian MacCraith:

It could well be, Chair, that before this process finishes we ask for a facility to go to the Minister of the day if there is a feeling there is room for more expertise, but we did not want to put an open-ended number here, so it is our current thinking that two is appropriate. Perhaps if there was a facility for an amendment that opened up in the circumstances where we felt there was additional need one could go to the Minister without having to, as the Chair says, go back through the legislative route.
