This week’s read-across
One AI-hallucination ruling landed on the docket this week. Small-N weeks are the norm — the pattern is set by the trailing 12-week average, not by any individual week’s count.
Open Law; Claude; ChatGPT was the most-implicated AI tool this week.
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.
