RvVb-A-2526-0597

RvVb · Mar 19, 2026

Direct answer

What happened in this matter?

The RvVb rejected the applicant's appeal and explicitly criticized the counsel for reckless use of ChatGPT. The court found that the counsel submitted fabricated citations, broken hyperlinks, and outdated legal authorities, which failed to meet the professional standards of diligence and clarity required in legal proceedings.

Why the court cared
The court reasoned that the counsel's reliance on AI-generated content violated the duty of professional diligence and integrity. It noted that the submissions were largely incoherent, contained fabricated sources that could not be verified, and relied on repealed law, thereby obstructing the court's ability to adjudicate the matter fairly.
Why it matters now
This case serves as a significant precedent for the professional duty of lawyers to verify AI-generated content. It demonstrates that courts will penalize counsel for submitting fabricated citations and outdated law, treating such conduct as a breach of the fundamental duties of dignity, integrity, and diligence.

Why this matter is tracked

In an administrative appeal regarding a building permit, the Belgian Council for Permit Disputes (RvVb) rejected the applicant's appeal and criticized the counsel's use of generative AI in their rebuttal (wederantwoordnota). The court identified multiple instances of AI-generated content, including fabricated hyperlinks (e.g., to a Stad Brugge management plan) containing 'utm_source=chatgpt.com' parameters, broken or irrelevant external links (Spotto, TomTom), and generic theoretical overviews unrelated to the case. Furthermore, the counsel relied on a repealed legal provision (art. 4.8.11 VCRO). The court characterized these practices as a lack of diligence and professional integrity, noting that the AI-generated submissions made it nearly impossible for the court and opposing parties to understand the legal arguments.

Operational lesson

This case serves as a significant precedent for the professional duty of lawyers to verify AI-generated content. It demonstrates that courts will penalize counsel for submitting fabricated citations and outdated law, treating such conduct as a breach of the fundamental duties of dignity, integrity, and diligence.

Tracked discrepancy record

4 citation, quotation, or authority issues are recorded in the source dataset.

  1. Fabricated: Exhibits & Submissions | Hyperlink claimed to point to the Stad Brugge 'beheerplan kleine stadsbossen' but the URL was incorrect and not connected to the alleged source; link included referral parameter 'utm_source=chatgpt.com'. Court flagged this as evidence of AI-generated/unreliable sourcing.
  2. Fabricated: Other | References to external web sources (Spotto, TomTom) in the reply included ChatGPT-linked URLs that returned errors or unrelated pages (404/'sold'), indicating unreliable or misrepresented sourcing.
  3. Fabricated: Exhibits & Submissions | The rebuttal contained lengthy, generic theoretical overviews (e.g., PFAS, measurement uncertainty, 'bouwpraktijk') not concretely tied to the dossier, which the court attributed to AI generation and treated as unreliable or irrelevant.
  4. Outdated Advice: Repealed Law | Wederantwoordnota relied on jurisprudence and wording tied to a former legal provision (art. 4.8.11 VCRO) that has been repealed for more than ten years; court treated this as outdated/misleading reliance.
