Judith Landberg's Lawsuit Is Dismissed After Lawyer Cited 3 Fictitious Cases
1 articles · Updated · 404 Media · Jun 4
Summary
Wednesday's dismissal ended Landberg's sidewalk-trip case after New York appellate judges found her lawyer, Michael Sanders, had cited at least three nonexistent cases and misrepresented 10 others.
A May 20 hearing turned into a 20-minute rebuke, with Justices Valerie Brathwaite Nelson and Hector LaSalle pressing Sanders on where the citations came from and warning he was invoking legal principles that do not exist.
Opposing lawyers for the property owner and New York City were also chastised for not flagging the apparent fabrications, with the court saying officers of the court had a duty to alert judges to such errors.
Sanders and his law firm were ordered to show cause why they should not be sanctioned, in a case the judges cast as part of a broader wave of likely AI-generated false citations reaching courts.

Overview
The Landberg lawsuit was dismissed on June 3, 2026, after attorney Michael Sanders and his firm submitted non-existent cases to the court. Justice LaSalle strongly criticized both Sanders and opposing lawyers for failing to check the legitimacy of these cases, calling it a profound breach of professional responsibility and due diligence. This led the appellate court to order Sanders and his firm to explain why they should not be sanctioned. The incident raised serious questions about legal standards and highlighted a significant lapse in ethical obligations, prompting formal sanctions proceedings and sparking wider concerns about integrity in legal practice.
