Lee. Lee’s reply brief in this case includes a citation to a non-existent case, which she Case 22-2057, Document 179, 01/30/2024, 3606904, Page2 of 12 3 admits she generated using the artificial intelligence tool ChatGPT. Because citation in a brief to a non-existent case suggests conduct that falls below the basic obligations of counsel, we refer Attorney Lee to the Court’s Grievance Panel, and further direct Attorney Lee to furnish a copy of this decision to her client, Plaintiff-Appellant Park.

172 (hereinafter, “Response”). Although Attorney Lee did not expressly indicate as much in her Response, the reason she could not provide a copy of the case is that it does not exist – and indeed, Attorney Lee refers to the case at one point as “this non- existent case.” Id. at 2. Attorney Lee’s Response states: I encountered difficulties in locating a relevant case to establish a minimum wage for an injured worker lacking prior year income records for compensation determination . . . .

Attorney Lee’s submission of a brief relying on non-existent authority reveals that she failed to determine that the argument she made was “legally tenable.” Cooter & Gell, 496 U.S. at 393.

What the text mentions

Pattern matches on the documents' text. Each line is a fact that the text contains the words, not a finding about the case.

Where this fits

This page is a record, not legal advice. It quotes the documents on file and lists what their text mentions. Read the decision at the source before relying on it, and check whether a later order changed it.

More from District Court, S.D. New York, from New York, or from 2025. The whole record is at court decisions on AI-hallucinated citations.

Every case in this record shares one cause: a citation reached a court without anyone opening it. What a citation gate is explains the mechanism that makes that impossible by construction; how to check an AI citation in five minutes is the manual version; the sanctions record is the essay this table grew out of.
