Domingo Beato-Estrella v. M. Arviza

M.D. Pennsylvania · Mar 16, 2026 · Keli M. Neary

Direct answer

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.

Operational lesson

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.

  1. Fabricated: Case Law | Petitioner cited 'Santos v. Warden Allenwood FCI, No. 1:17-CV-02116, 2018 WL 1178251 (M.D. Pa. Mar. 6, 2018)'; court found no such M.D. Pa. decision — the 2018 WL number corresponds to Certain Underwriters at Lloyd's, London v. Pettit (W.D. Wash.), unrelated to petitioner's claim.
  2. Fabricated: Case Law | Petitioner cited 'Rodriguez v. Ebbert, No. 3:14-CV-02404, 2015 WL 1810315 (M.D. Pa. Apr. 21, 2015)'; court found 2015 WL 1810315 corresponds to an unrelated Florida appellate decision (D.S. v. Dep't of Child. & Fams.), not the cited M.D. Pa. case.
  3. Fabricated: Case Law | Petitioner cited 'Cruz v. United States, No. 1:16-CV-01034, 2016 WL 8732312 (M.D. Pa. Dec. 16, 2016)'; court found 2016 WL 8732312 corresponds to Black Water Mgmt., LLC v. Sprenkle (E.D. Va.), not the cited M.D. Pa. decision.
  4. Misrepresented: Case Law | When using this court's docket numbers, petitioner identified cases (e.g., Firestone v. Rockovich, No. 1:17-CV-2116; Fagal v. Marywood Univ.; Drake v. Warden of Allenwood Low) that exist but are irrelevant to his claim — the court treated these as misattributed and not supportive of petitioner's position.
