The Australian Tax Office asked that the robodebt scheme "cease and desist" using taxpayer data, but was ignored by the Department of Human Services.
The royal commission into the controversial debt collection scheme was told an ATO officer concerned about the legality of robodebt asked the department to stop using taxpayer information.
"I ask that you cease and desist the usage of the data until we have your assurance around the data use," ATO director Tyson Fawcett wrote in a 2017 email addressed to the DHS.
