AI Hallucinations in Legal Filings: The Intellectual Property Court Imposes Sanctions for Fabricated Case Law

The integration of generative Artificial Intelligence into legal practice introduces significant procedural risks, as demonstrated by a recent ruling from the Intellectual Property Court (IPC). The court has imposed a judicial fine on an individual entrepreneur after their legal representative submitted a cassation appeal containing fabricated judicial precedents—a phenomenon commonly known as 'AI hallucinations.'

Case Background: Franchising and Contractual Compliance

The underlying dispute originated from a commercial concession agreement between the "Coffee Like" network and entrepreneur Alexander Antropov. The agreement granted the entrepreneur the right to utilize the company's trademark, proprietary "Network Standards" (know-how), and other intellectual property assets.

Following a series of audits, the franchisor identified violations of these operational standards. After a pre-trial claim remained unanswered, the right holder filed a lawsuit seeking 285,000 RUB in liquidated damages. Both the court of first instance and the appellate court upheld the franchisor's right to conduct unscheduled audits, remote monitoring, and "mystery shopping" exercises. However, the courts deemed the original penalty disproportionate and reduced the final award to 19,000 RUB.

The Procedural Failure: Generative AI and 'Phantom' Precedents

Upon reviewing the cassation appeal, the Intellectual Property Court found no substantive grounds to overturn the previous rulings. However, the court identified a severe procedural breach: the appeal contained twelve separate citations to non-existent judicial acts or misquoted findings that did not exist in the referenced documents.

During the hearing, the entrepreneur's representative attempted to mitigate the situation by citing a "technical error" and attributing the inaccuracies to the use of AI tools. The defense argued that these errors did not constitute a lack of respect for the court and that the client should not be held liable for the professional negligence of their legal counsel.

Legal Analysis and Conclusion

The court rejected these arguments, emphasizing that the duty of diligence remains with the legal professional regardless of the tools employed. The IPC imposed a judicial fine of 5,000 RUB on the entrepreneur, signaling a zero-tolerance approach toward the submission of unverifiable or fabricated data in court filings.

From a Tech & IP Law perspective, this case serves as a critical precedent for the legal community. While AI can enhance efficiency in drafting, the final verification of legal citations—the "human-in-the-loop" requirement—is not optional; it is a professional mandate. The use of LLMs (Large Language Models) without rigorous fact-checking creates not only a reputational risk for the lawyer but direct financial and procedural liability for the client.
