The National Anti-Corruption Commission has scrubbed from official freedom of information documents the name of its deputy leader who made the “decision” to not investigate over Robodebt.

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.

The sole person responsible for policing internal corruption at the National Anti-Corruption Commission is refusing to say whether an actual “investigation” has begun into the Robodebt referrals scandal.

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

National Anti-Corruption Commission boss Paul Brereton was present for the majority of a Robodebt decision meeting, despite claiming to have been “recused”.

The National Anti-Corruption Commission’s decision not to investigate officials at the heart of the Robodebt scandal — a decision it took a year to announce — comprises just two pages.
