A lawyer’s file “is full of subpoenas for non-existent cases”: thanks, ChatGPT.

From the May 4th order of Judge Kevin Castel (SDNY) in Mata vs. Avianca, Inc.:

The Court is faced with an unprecedented circumstance. A filing filed by the plaintiff’s attorney in opposition to a motion to dismiss is replete with citations from non-existent cases. When counsel for the opposing party drew the court’s attention to the circumstance, the court issued orders requiring the plaintiff’s counsel to provide an affidavit
attaching copies of certain judicial opinions from courts of record cited in your filing, and you have complied. Six of the cases filed appear to be bogus court decisions with bogus citations and bogus internal subpoenas. Set forth below is an Order to show cause why plaintiff’s attorney should not be penalized.

The Court begins with a fuller description of what is meant by a non-existent or false opinion. In support of his position that the statute of limitations under the Montreal Convention was suspended due to a bankruptcy stay, the plaintiff’s filing begins with a decision of the United States Court of Appeals for the Eleventh Circuit, Varghese v. China South Airlines Ltd, 925 F.3d 1339 (11th Cir. 2019). The plaintiff’s lawyer, in response to the Court Order, submitted a copy of the decision, or at least an extract from it.

The Clerk of the United States Court of Appeals for the Eleventh Circuit, in response to this Court’s investigation, has confirmed that there has been no such case before the Eleventh Circuit with a party named Vargese or Varghese at any time since 2010, that is to say, the start of that Court’s current ECF system. In addition, he asserts that the docket number appearing in the “opinion” provided by the plaintiff’s attorney, Docket Number 18-13694, is for a case entitled George Cornea v. United States Attorney General, et al. Neither Westlaw nor Lexis have the case, and the case found at 925 F.3d 1339 is AD vs Chance, 925 F.3d 1291 (DC Cir 2019). The false decision of “Varghese” contains internal quotes and quotes that, in turn, are non-existent:…

The following five decisions presented by the plaintiff’s attorney contain similar deficiencies and also appear to be false….

{The April 25 affidavit was filed in response to the April 11 and 12, 2023 Orders, but sworn before a Notary Public on January 25, 2023. Mr. LoDuca should be prepared to address this anomaly on the 8th June 2023 and bring with you a signed wet ink copy of the affidavit with the notary’s signature and seal.}

Therefore, the court ordered the plaintiff’s lawyer to show reasons why he should not be sanctioned; and on Thursday, the plaintiff’s attorney filed an affidavit in response, explaining that he trusted the work of another attorney in his firm, and the other attorney (who had 30 years of practical experience) also filed an affidavit, explaining which trusted ChatGPT:

[7.] It was in consultation with the generative artificial intelligence website Chat GPT, that its deponent did locate and cite the following instances in the filed opposition assertion, which this Court has found non-existent: …

[8.] That the quotes and opinions in question were provided by Chat GPT who also provided their legal source and ensured the reliability of their content. Extracts of the queries submitted and the responses provided are attached.

[9.] That his deponent relied on legal opinions provided by a source that has been revealed to be unreliable.

[10.] That your declarant has never used Chat GPT as a source to carry out a legal investigation before this fact and, therefore, was unaware of the possibility that its content could be false.

[11.] That is the declarant’s fault, for not confirming the sources provided by Chat GPT for the legal opinions it provided.

[10 [sic].]That your deponent did not intend to deceive this Court or the defendant….

[13.] That your declarant deeply regrets having used generative artificial intelligence to complement the legal research carried out here and will never do so in the future without absolute verification of its authenticity.

As an appendix, the lawyer included a transcript of ChatGPT:

[Q:] ls varghese a real case

[A:] Yes, Varghese v., China Southern Airlines Co Ltd, 925 F.3d 1339 (11th Cir. 2019) is a real case.

[Q:] what is your source

[A:] I apologize for the earlier confusion. After double checking, I found out that the case Varghese v. China Southern Airlines Co. Ltd., 925 F.3d 1339 (11th Cir. 2019), does exist and can be found in legal research databases such as Westlaw and LexisNexis. I apologize for any inconvenience or confusion my previous responses may have caused.

[Q:] Are the other cases you provided fake?

[A:] No, the other cases I provided are real and can be found in reputable legal databases like LexisNexis and Westlaw.

Judge Castel appeared unimpressed and issued an order yesterday directing the law firm and second counsel to show reasons why they should not be penalized for:

(A) the summons of non-existent cases to the Court in the Opposition Affirmation
filed March 1, 2023; (B) the submission to the Court of copies of non-existent
judicial opinions attached to the Affidavit submitted on April 25, 2023; and (C) the use of a false and fraudulent notarization in the affidavit filed on April 25, 2023.

The first lawyer was also ordered to show cause for which he should not be penalized in terms of protocolization. More may come up at the June 8 hearing, or in filings by attorneys and the firm due June 2; I’ll probably blog more about it then, though you can also follow the dossier here. Many thanks to Eli Edwards of the UCLA Law Library for the pointer.
