Claims by National Anti-Corruption Commission boss Paul Brereton that he “recused” himself from the Robodebt referrals have “no justification whatsoever” and are “simply wrong", says top former judge.

National Anti-Corruption Commission boss Paul Brereton made misleading statements to Attorney-General Mark Dreyfus over his management of conflicts of interest over Robodebt.

The long promised federal anti-corruption commission is marred by “silence and secrecy”, says top legal expert.

An investigation has been launched into the National Anti-Corruption Commission over its refusal to investigate referrals from the Robodebt Royal Commission.

Attorney-General Mark Dreyfus used fudged data to justify implementing the almost entirely secret National Anti-Corruption Commission, vastly understating the amount of NSW anti-corruption hearings held in public.
