Regional Labour Court · Jul 2, 2025
What happened in this matter?
The court imposed a monetary sanction of 5% of the updated value of the case against the claimant for bad-faith litigation. The judge determined that the claimant's counsel used AI to generate fabricated judicial precedents and nonexistent legal summaries, violating procedural duties of loyalty and good faith.
- Why the court cared
- The court reasoned that the use of AI to create fake precedents and súmulas to influence the judge constituted a grave violation of procedural loyalty, cooperation, and good faith under Articles 5 and 77, I of the CPC, and warranted a penalty under Article 793-B, V of the CLT.

Why this matter is tracked
Fabricated: Case Law | Initial petition cited non-existent judicial precedents to support the claim; the defense flagged the fabrications and the court recognized them as such and as bad-faith conduct. Outcome: Monetary Sanctions. Counsel for the claimant admitted to using an AI tool to draft the initial legal document without verifying its content. This resulted in the creation of non-existent judicial precedents to support the claimant's case. The court found this to be a serious violation of procedural loyalty and good faith, as it attempted to deceive the court and the opposing party. Consequently, the claimant was fined 5% of the updated value of the case for litigating in bad faith, although the lawyer's apologies were partially accepted, preventing a higher fine.
