"It was submitted for the Commonwealth in the appeal that the duty imposed upon a public servant cannot extend beyond the duty to take reasonable care to determine the correct answer to an inquiry by a member of the public, and, in the event that a legal issue concerning the construction of a statute arises, then to seek appropriate legal advice or warn the member of the public of the uncertainty. It was also put for the Commonwealth, whether in addition to or in the alternative, that a public servant cannot be under a duty to seek legal advice when he or she is unaware that any legal uncertainty exists and when that lack of awareness does not arise out of a failure to exercise reasonable care. Submissions of this nature, couched in the language of legal principle, are apt to confuse because they are really directed at the factual circumstances, and factual circumstances vary from case to case. In the present case the submissions raise the factual issue of the reasonableness of the conduct of the officers of the Commonwealth who were responsible for preparing and tendering the advice to the appellant. If the preparation and giving of that advice was in the circumstances done without reasonable care as to its accuracy, the appellant was entitled to succeed, subject to proof that the failure resulted in loss. The Commonwealth's case in this regard relied essentially on long-standing practices in the office of the Defence Force Retirement and Death Benefits Authority (the Authority) based on interpretations of the Act which had never been challenged. More precisely, reliance was placed on the lack of any doubt on the part of any Authority officer as to the correctness of the established Authority's view that commuted pensions were not to be treated as "transfer values" for the purposes of the Act. Authority staff spent a lot of time on the appellant's case, particularly in getting information from New Zealand. The Commonwealth sought to distinguish the situation in the present case from that in Rennie v Commonwealth of Australia (1995) 61 FCR 351 in which the Full Court of the Federal Court of Australia said at 365: ... However that is a finding on the facts, not a statement of a principle of law. The facts depend on the evidence. It may be, as was submitted on behalf of the Commonwealth, that the evidence in the present case about whether Authority staff knew that their view was not the only possible view is lacking or at least inconclusive. However, if that is so, either they should have been so aware or there was to be attributed to the Commonwealth the knowledge that the interpretation that its officers were putting on the legislation needed checking by someone competent to give legal opinion. In the circumstances, for a Court to so hold would not be to 'compel public servants to obtain legal advice even when they are satisfied that their view of the legislation is the only view open and no contrary position had been put to them' (as was put on behalf of the Commonwealth). In the present matter the appellant did challenge the established departmental standpoint. It was incumbent therefore on the Commonwealth through its staff to reflect upon the possibility that the appellant may have been correct. Furthermore, any such reflection would have then suggested to the Commonwealth that it would be advisable to get an opinion, from someone qualified to express it, on whether the Authority's practice was in accordance with the law. The arguments put by the appellant in letters written to the Authority on 19 November 1989 and 30 March 1991 in themselves should have put the Authority on notice that the departmental orthodoxy might be falsely based, and, further, if it was, then the Commonwealth stood to be liable in damages to the appellant. In this respect the Commonwealth is hardly to be compared with an inexperienced litigant or potential litigant who may not recognise a problem as one of a legal nature, who does not know where to turn for advice of a legal nature and who may have difficulty in affording such advice or indeed difficulty in understanding the advice when given. Whether the Authority had a legal officer on its staff or any officer with legal qualifications with the capacity to express a view on the merit of the interpretation of the Act that the appellant was urging does not appear to be answered in the evidence before the Magistrate. However if the Authority did not have a legal officer on its staff, the Commonwealth should have had in place arrangements, as was once common with Commonwealth instrumentalities, for the Authority to be able to consult with and receive advice from the Attorney-General's Department or the Australian Government Solicitor. On the evidence before the Magistrate, such advice was available and was eventually sought and availed of, but not until long after the appellant had lost whatever right he had to commute his pension."
