The variation in the computer _after the crew of the DC10 had been briefed_ (as Mr Chippindale realized) is the matter which is mentioned by the Commissioner in paragraph 44 and which in paragraph 45 is offered as the motive for what is there described as an immediate decision by the chief executive that no word of the matter was to become publicly known, with documents to be impounded and others destroyed. This information was given into Mr Chippindale's hands by Air New Zealand in a written statement on the day following his return from the crash site in Antarctica. The Chippindale report then states in paragraph 3.6 that the computer error had remained in the flight plans for some fourteen months. Then it is said: "3.7 Some diagrams and maps issued at the route qualification briefing could have been misleading in that they depicted a track which passed to the true west of Ross Island over a sea level ice shelf, whereas the flight planned track passed to the east over high ground reaching to 12450 feet AMSL. 3.8 The briefing conducted by Air New Zealand Limited contained omissions and inaccuracies which had not been detected by either earlier participating aircrews or the supervising Airline Inspectors." So these various matters (also mentioned by the Commissioner) were well within Mr Chippindale's knowledge. However he came to a final conclusion that pilot error had been involved as a probable cause of the accident while the Commissioner (who decided this was an incorrect finding) was satisfied instead that the cause of the accident was not pilot error at all. He said: "393. In my opinion therefore, the single dominant and effective cause of the disaster was the mistake made by those airline officials who programmed the aircraft to fly directly at Mt. Erebus and omitted to tell the aircrew. That mistake is directly attributable, not so much to the persons who made it, but to the incompetent administrative airline procedures which made the mistake possible. 394. In my opinion, neither Captain Collins nor First Officer Cassin nor the flight engineers made any error which contributed to the disaster, and were not responsible for its occurrence." Jurisdiction to Review Several important questions arise in this case. Is there jurisdiction in the Courts to review in such a context as this taking into account the ambit of ss. 3 and 4 of the Judicature Amendment Act 1972? And if there is such power is it by reason of the award of costs in this case? Or on grounds relating to excess of jurisdiction on the part of the Commissioner? Or considerations of natural justice? Or by reference to all three of those matters? For the reasons that follow we are satisfied that the findings are reviewable and that each one of those three matters is properly within the scope of the Court's jurisdiction.
