If that’s the case then they are very ignorant of parliament’s powers. The houses of parliament in Australia have the capacity to find someone in contempt of their house but if they did so the punishment is limited to up to 6 months in prison and/or a fine of up to $5,000 for an individual (or up to $25,000 for a corporation). But contempt of parliament is strictly limited to someone acting in a way to impede the free functioning of parliament. Being critical of a report made to a parliamentary committee is a very long bow to draw in claiming contempt of parliament.We realise that we haven't a hope in hell of getting anywhere, but we have the unmittigated gall to try for cash compensation as a result of our own stupidity.
If APA or Repsim have a problem with statements made about them to other people then they have recourse to defamation for damages. But fair and reasonable criticism is not defamation. I’ve had run ins with Peter Goon before where he has responded to any criticism of his work with a declaration of defamation and a demand for compensation or right of reply and so on. Such demands are totally baseless in law and can be ignored as vexatious attempts to silence fair and reasonable criticism.
