- Why the court cared
- Fabricated: Case Law | Citation “Matter of Knapp v Knapp, 225 AD2d 1010 (4th Dept 1996)” could not be located under that name and instead led to a different matter (Orange Steel Erectors v Newburgh Steel Products Inc.); court found it defective/unverified. || Fabricated: Case Law | Citation “Matter of Negron v St. Charles Hosp. & Rehab. Ctr., 121 AD3d 1427 (2d Dept 2014)” led to a different matter (People v Rojas) and did not support counsel's argument; court could not find the cited matter. || Fabricated: Case Law | Citation “Matter of Polizzi v Polizzi, 226 AD2d 581 (2d Dept 1996)” did not correspond to that matter and led to a different case (Epes v Healey); court found it defective/unverified. || Misrepresented: Case Law | Citation “Wells Fargo Bank, N.A. v Estwick, 160 AD3d 911 (2d Dept 2018)” exists but the opinion does not support the proposition asserted by counsel; misrepresentation of precedent.

Why this matter is tracked
In a civil action for rent arrears, the court identified multiple fabricated and misrepresented case citations in the plaintiff's affirmation. The court determined that several cited cases either did not exist, did not correspond to the names provided, or did not support the propositions for which they were offered. The court noted that these citations appeared to be generated by an artificial intelligence program. Plaintiff's counsel admitted to a lack of proper review for papers prepared by his office and submitted a formal apology to the court. The court rejected counsel's request to submit corrected papers, disregarded the defective legal support, and ultimately granted the defendants' motion to dismiss the complaint for lack of personal jurisdiction.
