A federal court in the Northern District of Mississippi has sanctioned all four lawyers involved in a case for using generative AI without verifying its output.

The court’s opinion in Withers v. City of Aberdeen states that the lawyers on both sides of the case used AI to generate legal memoranda, which included hallucinated case citations. The two out-of-state lawyers admitted to using generative AI for research and drafting the brief, but did not verify the accuracy of the information.

They claimed they were unaware of the potential for AI to produce inaccurate information, but the court’s opinion suggests that lawyers can no longer claim ignorance of this potential.

The two local counsel claimed they were unaware of their co-counsel’s use of AI, but admitted to not reviewing the briefs thoroughly.

The opinion notes that the court has previously acknowledged the benefits of using AI as a tool, but emphasizes that it is the responsibility of humans to ensure the accuracy and sincerity of the information presented.

Generative technology can produce words, but cannot attach sincerity, truth, or responsibility to what it writes. This case is not an isolated incident, as there have been numerous cases worldwide in which individuals have gotten in trouble for relying on generative AI that turned out to be inaccurate.

The AI Hallucination Database tracks these cases, and it appears that this may be the first time that all lawyers on both sides of a case have been sanctioned for using AI improperly. The court’s opinion serves as a reminder to lawyers of the importance of verifying the accuracy of information generated by AI and taking responsibility for the information presented in court.

The consequences of using generative AI improperly can be severe.

In a similar situation, the use of AI in legal research has been compared to the use of other tools, such as legal databases, which require human verification to ensure accuracy.

The key difference is that AI can generate text that appears to be authoritative, but may not be based on actual facts or cases. The case highlights the need for lawyers to be aware of the potential risks and limitations of using generative AI in legal research and to take steps to verify the accuracy of the information generated.

Lawyers can ensure that they are presenting reliable and trustworthy information to the court by verifying the accuracy of AI-generated text.

The court’s decision to sanction all four lawyers involved in the case serves as a reminder of the importance of taking responsibility for the information presented in court.
