Mr. Peter Whelan:

Again, it is down to legislation. The legislation is quite difficult. If we have a long and difficult criminal investigation and we find at the end of it that there is a dismissal in court or an acquittal, we may go into a disciplinary procedure then. Depending on the length of the first step, cases can take an increasing number of years. Sometimes it can be because we are waiting on court cases or coroner's inquests, which can take a considerable amount of time.
