Peterkin et al v. McIntyre et al
D. New Jersey · Decided 2026-06-26 · Warning · AI tool: Implied.
27 AI-hallucination sanctions decided between 2026-06-22 and 2026-06-28 (ISO week 2026-W26). 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: 27 sanctions filed the week of 2026-06-22 vs 20 sanctions the prior week (2026-06-15) — up 7 from the prior week.
27 rulings landed on the docket between 2026-06-22 and 2026-06-28. The most common recorded outcome this week was Warning (7 of 27). Of the 27 rulings, 2 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.
