  • United Financial Casualty Co. v. Greg Ball
    Court of Appeals for the Fourth Circuit · Mar 30, 2023
    AI 50

    The text consists solely of repeated document metadata with no substantive legal content, indicating it is not a genuine judicial opinion.

  • American Academy of Pediatrics v. James Uthmeier
    Court of Appeals for the Seventh Circuit · Sep 14, 2026 · Scudderconcurs and dissents
    AI 37

    Although much of the prose resembles authentic appellate writing, the co-occurrence of serious citation anomalies, likely fabricated future citations, and some polished essay-style structuring makes substantial AI generation likely.

  • United States v. Alexzandra Blanco

    AI 31

    The text otherwise reads like a conventional Eighth Circuit opinion with concrete facts, standard formatting, precise statutory/rule citations, and no chatbot-style framing or buzzword clusters, but the malformed Campbell citation is a notable isolated AI-like warning sign.

    AI 29

    Although the prose and structure otherwise resemble a genuine D.D.C. memorandum opinion, the assertion that Markwayne Mullin is the current Secretary of Homeland Security and the related substitution history are blatant factual/citation-style anomalies that strongly suggest synthetic or substantially AI-assisted drafting.

    The prose largely resembles a genuine appellate opinion, but multiple citation anomalies—especially the impossible-looking pin cites—are strong machine-generation tells that raise the likelihood of substantial AI assistance.

    The prose largely reads like a conventional judicial opinion, but the highly implausible official-capacity defendant substitution and possibly fabricated future case citations are strong hallucination-style signals that substantially raise the likelihood of AI assistance.

    Court of Appeals for the Seventh Circuit · Sep 14, 2026 · Kolarconcurs
    AI 25

    The prose mostly resembles a genuine appellate opinion with varied rhythm and many precise citations, but the internally implausible and erroneous citations are strong enough hallucination-like signals to put it in a moderate-risk range.

    AI 24

    The excerpt is largely plausible law-clerk style, but the cluster of suspect citations, citation-format anomalies, mechanical structure, and small procedural/formatting inconsistencies suggests a meaningful likelihood of substantial generative-AI assistance.

  • United States v. Isaac Loggins, Jr.
    Court of Appeals for the Eighth Circuit · Jul 10, 2026
    AI 24

    The prose largely resembles a genuine Eighth Circuit opinion, but multiple concrete citation and internal-fact inconsistencies of the kind LLMs often hallucinate raise the likelihood substantially above baseline.

    fabricated or implausible Supreme Court citation to Rutherford v. United States, 146 S.
