The future of the federal government’s anti-union, kangaroo court — the Royal Commission into Trade Union Governance and Corruption — is in doubt, following media revelations that the commissioner, retired High Court Justice John Dyson Heydon, accepted an invitation — not once, but twice — to speak at a Liberal Party fundraiser while serving on the body. The commission first sat on April 9 last year and media reports say Heydon received the invitation to speak via email just one day later, on April 10. He was approached again in March.
