47 As stated, there is widespread public interest in the proper administration of the prison system and the liberty and rights of the individual. I refer again to the remarks of Kellam J and Deputy President Galvin in Re Coburg Brunswick. Where there have been allegations of violence and misconduct by prison officers, and a detailed investigation has been carried out, it seems to me that the public interest requires that access be given to documents relating both to the relevant incident and to the investigation, subject, as stated, to the protection of the privacy of the individuals involved. In weighing up considerations in relation to these matters, the passage of time does seem to me to be relevant. Despite Mr Dennis' urgings, I am not greatly impressed by the threat posed to security by releasing, for example, information concerning the movements of an ambulance in excess of four years ago, or the somewhat neutral location of an implement which was found. The type of information contained in the disputed documents in this case seems to me to be vastly different from the type of information sought in cases such as Knight v CORE. In my view, exemptions based upon these provisions have not been made out, and s.50(4) would prevail in any event. In this regard, I might add that it seems to me to be in the public interest that the accounts of eyewitnesses to these events be available for inspection by and on behalf of the general public, even if the identity of the eyewitnesses is not disclosed.
