Expert Insight
The integration of AI in legal practice requires careful oversight to prevent errors that could jeopardize case outcomes.
June 17, 2026 · Legal Brief

Shahryar Mazaheri, a Toronto lawyer, has been ordered to pay $31,150 to the Law Society of Ontario after submitting AI-generated legal documents deemed 'gibberish. ' The Law Society Tribunal imposed what is believed to be the largest AI-related cost award by a Canadian court or tribunal. Mazaheri's documents cited non-existent cases and misrepresented existing ones, leading the tribunal to emphasize the risks of relying on artificial intelligence without proper verification.

This incident follows Mazaheri's provisional suspension in November 2024 due to his connection to a large-scale mortgage fraud linked to a deadly triple shooting. Despite his request to lift the suspension, the tribunal upheld it, citing his misuse of AI as significantly improper. UL Lawyers Legal Team is closely following these developments as they highlight the emerging challenges of integrating AI into legal practice.
