Tiffany K. v. Commissioner of Social Security

E.D. Michigan · Jan 16, 2026

Direct answer

What happened in this matter?

The court issued a formal warning to counsel for including a fabricated 'phantom' case citation in her brief, which the court attributed to the use of generative AI. The court admonished counsel that such conduct is not tolerated and noted that similar actions have resulted in sanctions in the past.

Why the court cared
Fabricated: Case Law | Counsel's brief included a non-existent case citation 'Fleck v. Comm’r of Soc. Sec.'; the Court identified it as a 'phantom' citation likely generated by AI and admonished counsel.
Why it matters now
Courts now name-and-shame 'phantom' citations as AI-generated — a single unverified cite is enough to trigger public admonishment.

Why this matter is tracked

In a Social Security disability appeal, the court admonished counsel for including a non-existent 'phantom' case citation, 'Fleck v. Comm’r of Soc. Sec.', in her briefing. The court identified this as a likely result of generative AI usage and warned counsel that such unconfirmed citations and AI use have previously led to sanctions in the court. While the court ultimately granted the plaintiff's motion for summary judgment and remanded the case due to errors in the ALJ's evaluation of medical listings and residual functional capacity, the court explicitly placed counsel on notice regarding the firm's briefing practices, including the use of AI and failure to comply with local rules regarding font size and issue identification.

Operational lesson

Courts now name-and-shame 'phantom' citations as AI-generated — a single unverified cite is enough to trigger public admonishment.
