Mr. Aidan O'Driscoll:

In respect of a decision by or the activities of the special investigations unit, the first line of appeal would be to the manager of the unit. This is normal with all our processes. The second line of appeal would be to our quality service unit, which resides in our corporate affairs area - a completely different line of the Department. If somebody was not satisfied with that, they could go to the Ombudsman and, ultimately, the courts.
