A former coalition minister and government departments failed to properly consider the personal heartbreak and harm stemming from the illegal robodebt scheme.
A former minister in charge of robodebt has denied responsibility for his department's failure to check the legality of the scheme and said he still believed it was lawful in the face of mounting issues.
Prime Minister Scott Morrison says Alan Tudge remains a "formal member" of his cabinet despite standing aside following allegations of abuse, which he denies.
