"... it is clear from the evidence that a very substantial and thorough investigation was carried out. It commenced on1 February 1994 ; it continued until13 September 1994 and there is an indication that it may still be continuing. In that period not only was the applicant interviewed on two occasions; but he went through a disciplinary hearings and an appeal hearing and it is clear also from the evidence that a number of other people were involved and statements were taken from them in respect of the matters that are produced in evidence today."
