Summary
A 13-count federal lawsuit by Executive MBA student Thierry Rignol accuses Yale of wrongly suspending him for a year and assigning an F after his final exam was flagged as AI-generated.
GPTZero flagged sections of Rignol’s Sourcing and Managing Funds exam, but he says the answers were entirely his own and argues AI detectors are unreliable and can misread formal writing by non-native English speakers.
Rignol says the punishment cost him valedictorian status despite being on track to finish first in his class, and he claims Yale’s disciplinary process was a sham.
Since February 2025, the case has grown to 125 docket entries and a third amended complaint, with Rignol also alleging Yale targeted his conservative views on smaller government, pro-business policy and DEI skepticism.
