Direct answer
What happened in this matter?
Misrepresented: Exhibits & Submissions | Party submitted ChatGPT-derived statements; Court disregarded them because the underlying question/prompt was unknown, so the content lacked reliable provenance. Outcome: Arguments rejected; No formal sanction but severe judicial criticism..
- Why the court cared
- The Court reasoned that a list generated by an AI program like ChatGPT, without rigorous control or verification, is inadmissible for evidentiary purposes. AI outputs lack the nuanced judgment necessary to assess "similar vehicles" under Art. 110 TFEU and Dutch bpm tax rules. It underscored that the test is based on the perceptions of a human average consumer, not algorithmic proximity
- Why it matters now
- If you cannot produce the exact prompt and verification trail, expect Dutch courts to discard the AI-derived argument entirely.
Why this matter is tracked
Misrepresented: Exhibits & Submissions | Party submitted ChatGPT-derived statements; Court disregarded them because the underlying question/prompt was unknown, so the content lacked reliable provenance. Outcome: Arguments rejected; No formal sanction but severe judicial criticism..
AI Use
The appellant relied on ChatGPT to generate a list of ten "economically comparable" vehicles for purposes of arguing a lower trade-in value to reduce bpm (car registration tax). The Court noted this explicitly and criticized the mechanical reliance on AI outputs without human verification or contextual adjustment.
Hallucination Details
ChatGPT produced a list of luxury and exotic cars supposedly comparable to a Ferrari 812 Superfast. The Court found that mere AI-generated association of vehicles based on "economic context and competition position" is insufficient under EU law principles requiring real-world comparability from the perspective of an average consumer.
Ruling/Sanction
The Court rejected the appellant’s valuation arguments wholesale. It stressed that serious, human-verified reference vehicle comparisons were mandatory and that ChatGPT lists could not establish the legally required comparability standard under Dutch and EU law (Art. 110 TFEU). No monetary sanction imposed, but appellant’s entire case collapsed on evidentiary grounds.
Key Judicial Reasoning
The Court reasoned that a list generated by an AI program like ChatGPT, without rigorous control or verification, is inadmissible for evidentiary purposes. AI outputs lack the nuanced judgment necessary to assess "similar vehicles" under Art. 110 TFEU and Dutch bpm tax rules. It underscored that the test is based on the perceptions of a human average consumer, not algorithmic proximity.
Operational lesson
If you cannot produce the exact prompt and verification trail, expect Dutch courts to discard the AI-derived argument entirely.
