Direct answer
What happened in this matter?
Fabricated: Case Law | Plaintiff cited a non-existent case the Court could not locate. Outcome: Complaint dismissed with prejudice; no Rule 11 sanctions imposed, but clear judicial warning on AI misuse and citation verification duties.
- Why the court cared
- The Court noted that while AI may be a helpful tool for pro se litigants, its use does not relieve them of the obligation to verify that every citation is real. The submission of fictitious legal authorities, even if inadvertent, is improper and may warrant sanctions. Here, the repeated failure to plead a viable claim after multiple amendments led to dismissal with prejudice

Why this matter is tracked
Fabricated: Case Law | Plaintiff cited a non-existent case the Court could not locate. Outcome: Complaint dismissed with prejudice; no Rule 11 sanctions imposed, but clear judicial warning on AI misuse and citation verification duties.
AI Use
Plaintiff’s proposed second amended complaint included multiple fictitious legal authorities, phrased in language suggesting generative AI use (e.g., “Here are some relevant legal precedents...”). The court stated it “bears some of the hallmarks of an AI response” and noted that the citations appeared to have been “invented by artificial intelligence (‘AI’).”
Hallucination Details
The court could not locate the following cited cases:Ford v. District of Columbia, 70 F.3d 231 (D.C. Cir. 1995)Davis v. District of Columbia, 817 A.2d 1234 (D.C. 2003)Ward v. District of Columbia, 818 A.2d 27 (D.C. 2003)Reese v. District of Columbia, 37 A.3d 232 (D.C. 2012)These were used to allege a pattern of constitutional violations by the District but were found to be fabricated.
Ruling/Sanction
The court denied Plaintiff’s motion to file a second amended complaint and dismissed the federal claims with prejudice. No formal Rule 11 sanctions were imposed, but the court emphasized the importance of verifying legal citations, citing Mata v. Avianca as precedent for how courts have responded to similar AI-related misuse.
Key Judicial Reasoning
The Court noted that while AI may be a helpful tool for pro se litigants, its use does not relieve them of the obligation to verify that every citation is real. The submission of fictitious legal authorities, even if inadvertent, is improper and may warrant sanctions. Here, the repeated failure to plead a viable claim after multiple amendments led to dismissal with prejudice.
