How these briefs are made

Each brief starts from the structured record in the AI Vortex Legal AI Risk database, which builds on Damien Charlotin's AI Hallucination Cases Database (CC BY 4.0). We then read the court record itself and write only what it supports. Where the order does not say something, the brief says so.

For counts by year, country, state and consequence, see the AI hallucination court cases statistics page.
