Allbaugh v. University of Scranton

U.S. District Court, Middle District of Pennsylvania · M.D. Pa. · Pennsylvania bar guidance

Conduct

Pro se former attorney cited a fabricated Third Circuit decision (Dreibelbis v. Reading) in opposition to motion to dismiss.

Consequence

$1,000 penalty payable to Clerk of Court; held to a heightened Rule 11 standard given prior legal training.

Lesson

Pro se status reduces, but does not eliminate, Rule 11 exposure for hallucinated citations. Legal training raises the bar.

Summary

Pro se plaintiff Brent Allbaugh, a former attorney, filed an opposition to a motion to dismiss (Doc. 14, June 2, 2025) that cited Dreibelbis v. City of Reading, No. 23-1900, 2024 WL 188858 (3d Cir. Jan. 17, 2024). No such decision exists. Judge Karoline Mehalchick found the citation fabricated, identified concurrent violations of the court's local rules and the chambers' standing order on generative AI use, and concluded that Rule 11 was triggered. The court placed the monetary penalty at the lower end of the typical $1,000 to $6,000 range applied to similar pro se hallucination matters, citing plaintiff's pro se status, but held him to a heightened standard given his prior legal training.

What sanction did the court impose?

$1,000 monetary penalty ordered payable to the Clerk of Court within 30 days. The court declined to dismiss the underlying matter on Rule 11 grounds but warned plaintiff that further fabricated citations would trigger escalation.

Why does Allbaugh v. University of Scranton matter for law firms using AI?

Allbaugh is the cleanest M.D. Pa. application of Judge Mehalchick’s standing GenAI order to a sanction. The fabricated case at issue, Dreibelbis v. City of Reading, is the kind of citation a generative tool will produce when asked for circuit precedent on a doctrine that the actual circuit has not addressed in the requested form: a plausible-sounding caption, a plausible-looking docket number, a plausible-looking Westlaw reporter, and no underlying case. Cite-validation tools that check format compliance without resolving the citation against a primary index will return false positives.

The court’s heightened-standard framing is the part most worth carrying forward. Judge Mehalchick acknowledged the typical $1,000 to $6,000 sanctions band for pro se litigants in this posture and placed Allbaugh at the lower end because of his pro se status. She then cited his prior legal training as the reason the lower-end posture, rather than a downward variance below it, was the right answer. For Pennsylvania attorneys with personal pro se matters in the Middle District, the implication is that the court will not treat a former attorney as a typical pro se litigant for Rule 11 purposes; the same verification discipline a firm would apply to client-facing work applies to personal filings, and AI-assisted drafts in personal matters carry the same exposure.

Implications for your firm

Operational steps a firm reading this case may wish to consider documenting. Strategic and rule-application calls belong to your firm's attorneys.

  • Document a citation-verification step that confirms each cited case exists in a real reporter or docket, not just that the citation format is well-formed.
  • Train any attorney appearing pro se in personal litigation that pro se status does not displace Rule 11 obligations for AI-generated drafts.
  • Review the chambers standing-order list for any M.D. Pa. matter and confirm AI-use certifications track Mehalchick's standing order, not just the local rules.
