The Financial Remedies Journal has published a blog by Jennifer Lee on ‘Fabricated Judicial Decisions and “Hallucinations” – a Salutary Tale on the Use of AI’.

The blog addresses the use of AI, and in particular ‘generative AI’ such as ChatGPT, which comes with an entirely new set of opportunities and pitfalls for judges and practitioners, whether in the Financial Remedies Court or in other courts/jurisdictions. This was starkly demonstrated in the extraordinary, recent case of Felicity Harber v HMRC [2023] UKFTT 1007 (TC), in the Tax Chamber (FTT), in which a party cited numerous ‘fake’ decisions generated by AI.

The blog also covers guidance from the Bar Council, the SRA and the judiciary on the appropriate use of AI for legal practitioners.
