Domingo Beato-Estrella v. M. Arviza
M.D. Pennsylvania · Mar 16, 2026 · Keli M. Neary
What happened in this matter?
The court issued a formal warning to the pro se petitioner regarding the submission of fabricated and misrepresented case law. The court dismissed the habeas petition without prejudice for lack of subject matter jurisdiction, noting that the petitioner's reliance on AI-generated hallucinations violated the requirement to cite actual, relevant law.
- Why the court cared
- The court reasoned that the petitioner's cited cases were either non-existent or irrelevant to the subject matter of the petition. It noted that AI programs are known to hallucinate and cautioned the petitioner that pro se status does not excuse the failure to cite actual, verifiable law.
- Why it matters now
- This case illustrates judicial intervention against pro se litigants using AI tools to generate fake citations. It reinforces the court's expectation that all litigants, regardless of representation status, must verify the existence and relevance of cited authorities.
Why this matter is tracked
In a habeas corpus petition, pro se petitioner Domingo Beato-Estrella cited three non-existent cases and misrepresented several others to support his challenge against an ICE detainer. The court identified that the cited Westlaw reporter numbers corresponded to unrelated litigation in other jurisdictions, and the cited docket numbers corresponded to irrelevant cases within the Middle District of Pennsylvania. The court dismissed the petition for lack of subject matter jurisdiction, noting that the petitioner's claims were premature and lacked legal support. The judge explicitly cautioned the petitioner regarding the risks of using AI tools that generate hallucinations, emphasizing that pro se litigants must ensure the accuracy of their legal research and citations to avoid presenting fabricated authority to the court.
