Mazaheri v Law Society of Ontario
Law Society Tribunal (ON) · Decided 2026-06-12 · Adverse Costs Order · Penalty: 31150 CAD · AI tool: Grok.
35 AI-hallucination sanctions decided between 2026-06-08 and 2026-06-14 (ISO week 2026-W24). Every ruling below is sourced from the public docket — case name, decided date, outcome, AI tool implicated (when named), and any monetary penalty language pulled verbatim from the ruling.
Week over week: 35 sanctions filed the week of 2026-06-08 vs 30 sanctions the prior week (2026-06-01) — up 5 from the prior week.
35 rulings landed on the docket between 2026-06-08 and 2026-06-14. The most common recorded outcome this week was Warning (5 of 35). Of the 35 rulings, 11 carried an explicit monetary penalty in the ruling text.
Implied was the most-implicated AI tool this week (courts rarely require the attorney to name the tool by product name on the record; “Implied” means the ruling described an AI-generated brief without a product name).
The pattern each week is remarkably stable: existence failures (Layer 1) dominate. Attorneys file briefs containing citations that do not exist in any primary source — usually because a general-purpose LLM fabricated the citation and no deterministic pre-filing check caught it. Every ruling below is a preventable filing. See /verify for the pre-filing tool.
