My understanding is that there was a legislative debarment of Supplementary Estimates, that is, in terms of an additional spend.

My final question is on the Tánaiste's preamble, in which she made reference to a sum of €4 million for the Schengen Information System II, SIS II. I do not for one moment suggest knowledge of this, but it is my understanding that Ireland has not signed up to the Schengen agreement. or did I not notice it happening while I was dozing? Is there a relationship between the Schengen agreement and the SIS II? Will the Tánaiste elaborate on the matter in order that I might have a better understanding of what is involved in the SIS II?
