Although this is not an appeal on causation or on any other aspect of the Commission's report, the issues with which this Court is properly concerned--the extent of the Commissioner's powers in this inquiry, and natural justice--cannot be considered without reference to the issues and evidence at the inquiry. We are very conscious that we have not had the advantage of seeing and hearing the witnesses. It can be very real, as all lawyers know. It is true that the kind of analytical argument we heard from counsel, with concentration focused on the passages of major importance in the report and the transcript of evidence, can bring matters into better perspective than long immersion in the details of a case. Necessarily this Court is more detached from the whole matter than was the Commissioner. And several different judicial minds may combine to produce a more balanced view than one can. But as against those advantages, which we have had, there is the advantage of months of direct exposure to the oral evidence, which he had. So we have to be very cautious in forming opinions on fact where there is any room for different interpretations of the evidence.
Having stressed those limitations on the role of this Court, we think it best to state immediately in general terms the conclusions that we have reached in this case. Then we will go on to explain the background, the issues and our reasoning in more detail. Our general conclusion is that the paragraph in the report (377) in which the Commissioner purported to find that there had been 'a pre-determined plan of deception' and 'an orchestrated litany of lies' was outside his jurisdiction and contained findings made contrary of natural justice. For these reasons we hold that there is substance in the complaints made by the airline and the individuals. Because of those two basic defects, an injustice has been done, and to an extent that is obviously serious. It follows that the Court must quash the penal order for costs made by the Commissioner against Air New Zealand reflecting the same thinking as paragraph 377.
In 1977 Air New Zealand began a series of non-scheduled sightseeing flights to the Antarctic with DC10 aircraft. The flights left and returned to New Zealand within the day and without touching down en route. The southernmost point of the route, at which the aircraft turned round, was to be at about the latitude of the two scientific bases, Scott Base (New Zealand) and McMurdo Station (United States), which lie about two miles apart, south of Ross Island. On Ross Island there are four volcanic mountains, the highest being Mount Erebus, about 12,450 feet. To the west of Ross Island is McMurdo Sound, about 40 miles long by 32 miles wide at the widest point and covered by ice for most of the year.
