Preston House v. TH Foods, Inc.
D. Nevada · Decided 2026-06-18 · Briefs struck; Warning · AI tool: Implied.
20 AI-hallucination sanctions decided between 2026-06-15 and 2026-06-21 (ISO week 2026-W25). 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: 20 sanctions filed the week of 2026-06-15 vs 35 sanctions the prior week (2026-06-08) — down 15 from the prior week.
20 rulings landed on the docket between 2026-06-15 and 2026-06-21. The most common recorded outcome this week was Warning (6 of 20). Of the 20 rulings, 1 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.
