- Rignol challenges GPTZero’s reliability and alleges political bias.
- Yale says he returned from suspension and has graduated.

## Summary

Yale Executive MBA student Thierry Rignol has brought a 13-count federal lawsuit after being suspended for a year and given an F over allegations that he used generative AI in a final exam. He says an unreliable AI detector, GPTZero, wrongly interpreted his polished writing as AI-generated and that Yale’s disciplinary process was politically motivated; Yale disputes his account and says he has since returned and graduated.

The dispute began after Rignol’s four-hour, open-book but closed-internet exam in a finance-related course was flagged as unusually long, with GPTZero identifying sections as likely AI-written. Rignol, who paid $208,500 in tuition, is seeking unrestricted damages, reversal of the grade, expungement of disciplinary records and readmission, despite Yale saying he has already completed the programme.
