Damned if You Do, Damned if You Don't: Professional Negligence Liability in the Age of AI
Key Takeaways
- ▸Professional negligence liability may arise both from improper AI use and from failing to use available AI tools that could improve outcomes
- ▸The legal profession faces competing pressures: traditionalists warn of AI risks while advocates argue that clients will demand AI efficiency for competitive costs
- ▸As AI tools become more reliable, professional standards will evolve to clarify when AI use is expected or required, shifting the liability landscape
Summary
In a landmark legal address at Lincoln's Inn, Sir Geoffrey Vos, Senior Lord of Appeal in Ordinary, examines the emerging professional negligence landscape created by artificial intelligence adoption in professional services. The address identifies a central paradox: as AI tools become more capable and integrated into professional practice, lawyers, doctors, accountants, and other professionals may face liability both for using AI incorrectly and for failing to use available AI tools when they could improve outcomes. Vos presents two competing schools of thought—traditionalists who warn of AI's dangers (hallucinations, bias, accuracy risks) and advocates who argue that clients will soon demand AI-assisted services for efficiency and cost.
The analysis draws parallels across professions, including medicine, where doctors might be liable for misusing AI diagnostic tools or for failing to deploy them when available. Vos concludes that as AI integration accelerates and tools become more reliable through database integration and improved LLMs, the legal system will need to establish new professional standards defining when AI use is expected, optional, or prohibited. This creates a 'damned if you do, damned if you don't' scenario where professionals must navigate competing risks of over-reliance on AI and negligent failure to adopt beneficial technology.

Editorial Opinion
Sir Geoffrey Vos identifies a genuine inflection point in professional practice: the transition from 'AI is optional' to 'AI is expected' happens suddenly, creating a window where liability rules are unsettled and practitioners face genuine risk either way. Rather than resisting AI, the profession needs clear guidance on responsible use—a framework that acknowledges both the power and the limits of these tools.
