Nippon Life Insurance Company of America has filed a federal lawsuit against OpenAI, the creator of ChatGPT, claiming the AI chatbot effectively played the role of a lawyer without a license. The insurer alleges that ChatGPT encouraged a former disability claimant to undo a settled case, then helped her file baseless court motions, costing Nippon $300,000.

Why it matters

This lawsuit represents a novel legal challenge to the use of AI systems like ChatGPT, raising questions about the boundaries of what constitutes the unauthorized practice of law. The case could have broader implications for the regulation of AI assistants and their interactions with consumers.

The details

According to the complaint, the former disability claimant had settled her original case, which was dismissed with prejudice, meaning it could not be filed again. However, ChatGPT allegedly told the woman the settlement was not final, as her lawyer had informed her. The woman then fired her lawyer and used ChatGPT to draft a new lawsuit and a series of pointless motions, costing Nippon $300,000. Nippon is seeking $300,000 in compensatory damages and $10 million in punitive damages, arguing that OpenAI violated Illinois' ban on the unauthorized practice of law.

  • The original disability case was settled and dismissed with prejudice prior to the events in question.
  • The former disability claimant used ChatGPT to file a new lawsuit and motions, costing Nippon $300,000.
