QWYN and Commissioner of Taxation

Administrative Review Tribunal of Australia · Feb 5, 2025

Direct answer

What happened in this matter?

The Tribunal rejected the applicant's submissions after finding that the applicant relied on a fabricated quote from a legislative Explanatory Memorandum generated by Microsoft Copilot. The Tribunal affirmed the Commissioner of Taxation's decision, concluding that the applicant's reliance on unverified AI-generated content failed to meet the party's duty to assist the Tribunal.

Why the court cared
The Tribunal reasoned that the applicant's reliance on unverified AI-generated material was inconsistent with the duty to assist the Tribunal in achieving its statutory objectives. The Tribunal found that the AI-generated quote did not exist in the cited Explanatory Memorandum and that the submission of such material impeded the efficient resolution of the application.

Why this matter is tracked

False Quotes: Doctrinal Work | Applicant relied on a Copilot-generated quote from the Explanatory Memorandum to the Taxation Laws Amendment (Superannuation) Bill 1992 stating a 15% rebate applies to all disability pensions (taxed and untaxed). The Tribunal checked the EM, found no such paragraph (no para 2.20) and no similar language, concluding it was an AI hallucination. Outcome: The Tribunal affirmed the decision under review, rejecting the applicant's submissions based on the AI-generated content.. "The Applicant engaged the Copilot [Microsoft’s Artificial Intelligence product] in a range of probing questions pertaining to superannuation and taxation matters, upon which in part, it returned the following responses:The Explanatory Memorandum to the Taxation Laws Amendment (Superannuation) Bill 1992, which introduced the new regime taxing superannuation benefits, states in paragraph 2.20 that “the Bill will provide a tax rebate of 15 per cent for disability superannuation pensions. This will apply to all disability pensions, irrespective of whether they are paid from a taxed or an untaxed source. The rebate recognises that disability pensions are paid as compensation for the loss of earning capacity and are not merely a form of retirement income.I have examined the Explanatory Memorandum to the Taxation Laws Amendment (Superannuation) Bill 1992. I was unable to locate any paragraph in that document in the same or similar terms to the paragraph generated by Copilot. It did not contain a paragraph 2.20.It has been noted by others that AI bots are prone to hallucinations.[35] That appears to be what has happened here. It is my assessment that submitting unverified material generated by AI, is not consistent with a party’s duty to use their best endeavours to assist the Tribunal to achieve its statutory objectives. To expect the Tribunal to read and consider material which a party does not know is authentic impedes the Tribunal’s attempts to provide a mechanism of review that ensures that applications are resolved as quickly and with as little expense as a proper consideration of the issues permits.Nothing in the remainder of the applicant’s submissions altered my view that the untaxed element of the benefit should be taxed under Subdivision 301-B."
