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.

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.

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.

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.

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.

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