A report by anti-corruption barrister Geoffrey Watson SC, commissioned by the CFMEU, has alleged violence and misconduct by union leaders Michael Ravbar and Jade Ingham. The report, which was based on 56 interviews and numerous documents, accused the pair of orchestrating a campaign of violence against their opponents. The inquiry into the report has raised questions about Watson's record-keeping, with his lawyer suggesting he may have left out important documents. The inquiry has also heard allegations that former Labor minister Grace Grace threatened to cancel the contract of developers working on the Toowoomba Second Range Crossing unless they worked with the CFMEU.
