I believe the late Justice Mahon's famous words "orchestrated litany of lies" could well be applied to this case.
That quote comes from the Erebus (TE901) Royal Commision para 377. Justice Mahon's words could be equally about the TC-T story.
“The palpably false sections of evidence which I heard could not have been the result of mistake, or faulty recollection. They originated, I am compelled to say, in a pre-determined plan of deception. They were very clearly part of an attempt to conceal a series of disastrous administrative blunders and so… I am forced reluctantly to say that I had to listen to an orchestrated litany of lies.”
