The Amsterdam District Court penalized an attorney representing a defendant in a business-sale dispute after she cited a non-existent 2004 court ruling, apparently generated by an AI tool, and then submitted additional fabricated citations when the first was challenged. The court called the conduct “reprehensible” and imposed an extra €2,315.50 in process costs on the attorney’s client, on top of standard litigation costs. No underlying AI system was named in the ruling.
