This week’s read-across

24 rulings landed on the docket between 2025-10-20 and 2025-10-26. The most common recorded outcome this week was Warning (7 of 24). Of the 24 rulings, 3 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.
