Dyson Heydon will not step down as commissioner investigating corruption in trade unions, having decided to ignore the widespread perception of his political bias.
Whatever else he might be, Heydon is no fool. When he accepted the job as royal commissioner he knew what was expected of him.
The commission was set up as a political witch-hunt into unions, designed to give the Coalition government an issue which it thought it could win the next election with.
Heydon was happy to oblige and has been handsomely paid for doing so.
