Ms Helen Dixon:

It is difficult to add up fully the internal cost of the investigation in terms of resources applied to it. A lead investigator who heads up our special investigations, Tony Delaney, led on the investigation side. He used resources from throughout the organisation in the various strands of the investigation. There was significant involvement from Anna Morgan's team. She heads up the legal division of the Data Protection Commission. Certainly in the months prior to the report being issued two staff were working full-time on it.
