I think it does. The important element is that it relates to the investigation of a serious offence or a threat to the security of the State and that it must also be the least intrusive means available, it must be proportionate and of a scale that is reasonably required to achieve the objectives for which it is being sought. We were quite careful in drafting head 8 and in providing for the criteria. We were greatly helped by Mr. Justice Murray's report in that regard.
