What Happened
A Deloitte report commissioned by Australia's Department of Employment and Workplace Relations to review its welfare compliance system was found to contain fabricated academic citations, phantom footnotes, a made-up quote attributed to a federal court judge, and references to nonexistent paragraphs of a court ruling. A University of Sydney researcher flagged roughly 20 errors, and Deloitte quietly republished a corrected version disclosing that Azure OpenAI GPT-4o had been used. Deloitte agreed to repay the final installment of the AU$440,000 contract.
Impact
Deloitte issued a partial refund to the government and suffered international reputational damage, intensifying scrutiny of AI use in consulting deliverables for public-sector clients.
Cost: Partial refund of AU$440,000 (~US$290,000) contract
How to Prevent This
- Require disclosure of any generative AI use in client deliverables before publication
- Verify every citation, quote, and legal reference against primary sources
- Mandate subject-matter-expert review of AI-assisted analytical sections
- Contractually define AI-use standards and audit rights in government engagements
- Run automated citation-checking tools against academic and legal databases prior to delivery
