01
Factual background & dispute
- The lawyers’ leave-to-appeal submissions contained fabricated case citations.
- The researcher denied using ChatGPT. A passage admitting AI use quoted the separate Parker case and did not establish the source in this dispute.
- Two additional hearings investigated the citations, but their precise origin remained unresolved.
02
Core issues & judicial focus
- Whether a legal team may rely on generative AI for case law research
- What verification duties apply to legal practitioners who sign and submit court filings
- How costs and professional responsibility are allocated when hallucinated citations cause procedural waste
03
Judicial finding & holding
- Leave to appeal was refused.
- The firm was ordered to pay the costs of the two additional hearings, and the matter was referred to the Legal Practice Council.
- Referral was not a final disciplinary sanction. The judgment did not establish that ChatGPT generated the citations in this case.
04
Practical risk implications
01Legal citations should retain links to authoritative databases alongside copies of original texts.
02Candidate attorneys, instructing attorneys, and counsel must maintain tiered review records.
03The use of generative AI tools does not shift professional responsibility away from the practitioners who sign and submit filings.
