NLJ this week: Experts warned—AI use must be transparent

244923
New guidance seeks to bring order to the growing use of artificial intelligence (AI) in expert evidence. Writing in NLJ this week, Minesh Tanna and David Bridge of Simmons & Simmons set out a framework stressing ‘transparency’, ‘explainability’ and ‘reliability’

While AI offers speed and data-processing power, risks include bias, hallucinations and loss of privilege.

The guidance categorises use into low, high-risk and prohibited, warning experts remain ultimately responsible for their opinions. Courts may soon expect disclosure of AI use, with one suggestion that reports should explain ‘how & why AI has been used’. Notably, Lord Neuberger hints future criticism may fall on those who fail to use AI at all.

The direction of travel is clear: AI is here to stay, but careless reliance could see evidence unravel under scrutiny.
