Hallucination AI in the case of Mike Lindell serves as a striking warning: NPR

The CEO of MyPillow, Mike Lindell, arrives during a gathering of supporters of Donald Trump near the residence of Trump in Palm Beach, Florida, on April 4, 2023. On July 7, 2025, the lawyers of Lindell were sentenced to a fine of thousands of dollars for having submitted a legal deposit with errors generated by AI-AI.

A federal judge ordered two lawyers representing the CEO of MyPillow, Mike Lindell, in a defamation case of Colorado to pay $ 3,000 each after having used artificial intelligence to prepare a legal file filled with a multitude of errors and quotes of cases which did not exist.

Christopher Kachouroff and Jennifer Demaster violated the judicial rules when they filed the document in February filled with more than two dozen errors – including hallucinated affairs, which means that false affairs made up of AI tools, Judge Nina Y. Wang of the American district court of Denver judged on Monday.

“Notwithstanding any suggestion on the contrary, this court does not draw any joy from sanctioning the lawyers who appear before him,” wrote Wang in his decision. “Indeed, the federal courts are based on the aid of lawyers as a courtyard of the Court for the effective and equitable administration of justice.”

The use of AI by lawyers in court is not itself illegal. But Wang found that lawyers violated a federal rule which forces lawyers to certify that the allegations they do before the court are “well founded” in the law. It turns out that false cases do not meet this bar.

Kachouroff and Demaster did not respond to the request for NPR comments.

The judicial file chased by errors was part of a defamation case involving Lindell, the creator of Mypillow, the president of President Trump and the theorist of the conspiracy known to broadcast lies on the 2020 elections. Last month, Lindell lost this case, which was discussed before Wang. He was ordered to pay Eric Coomer, a former employee of Dominion voting systems, based in Denver, more than $ 2 million after saying that Coomer and Dominion used electoral equipment to return the votes to Joe Biden.

Financial sanctions, as well as reputation damage, for the two lawyers, are a brutal reminder for lawyers who, like many others, are increasingly using artificial intelligence in their work, according to Maura Grossman, professor at the University of Waterloo University law, David R. Cheriton School of Computer Science and an assistant professor at the Osgood Hall Law School York.

Grossman said that fines of $ 3,000, “in the scheme of things, were reasonably light, given that it was not non -sophisticated lawyers who would really not know. The kind of errors that were made here … were blatant.”

There was a crowd of high level cases When the use of a generative AI went wrong for lawyers and other persons depositing judicial affairs, said Grossman. It has become a familiar trend in the hearing rooms through the United States: lawyers are sanctioned to submit queries and other judicial files filled with cases of cases which are not real and were created by a generative AI.

Damien Charlotin follows judicial affairs from around the world where generative AI produced hallucinated content and where a court or court specifically levied from warnings or other sanctions. There are 206 cases identified from Thursday-and it’s only since spring, he told NPR. There have been very few cases before April, he said, but for months since there have been cases “appearing every day”.

The Charlotin database does not cover each case where there is a hallucination. But he said: “I suspect there are many, many, much more, but just a lot of courts and games prefer not to remedy them because it is very embarrassing for all the people involved.”

The fine of $ 3,000 for each lawyer, wrote Wang in his prescription this week, is “the least serious sanction to dissuade and punish the defense lawyer in this case”.

The judge wrote that the two lawyers have provided no appropriate explanation on how these errors – “most elegantly, the quotation of cases which do not exist” – occurred.

Wang also said that Kachouroff and Demaster were not to come when they were asked if the motion had been generated using artificial intelligence.

Kachouroff, in response, said in court documents that it was requesting which “mistakenly submitted” a version of this file of this file rather than the right copy, which was more carefully published and did not include hallucinated cases.

But Wang was not convinced that the submission of the deposit was an “inadvertent error”. In fact, she called Kachouroff for not having been honest when she questioned him.

“It is only if this court asked Mr. Kachouroff directly if the opposition was the product of a generative artificial intelligence that Mr. Kachouroff admitted that he in fact used generative artificial intelligence,” wrote Wang.

Grossman advised other lawyers who find themselves in the same position as Kachouroff not to try to cover him and to make fun of the judge as soon as possible.

“You are likely to get a more severe penalty if you don’t coerate,” she said.

Charlotin has found three main questions when lawyers or others use AI to deposit court documents: the first are the false cases created or hallucinated by AI chatbots.

The second is that AI creates a false quote from a real case.

The third is more difficult to spot, he said. It is at this point that the quote and the name of the case are correct, but the cited legal argument is not really supported by the case which is obtained, said Charlotin.

This case involving MyPillow lawyers is just a microcosm of the growing dilemma of how courts and lawyers can find the balance between welcome to technology that changes life and use it in a responsible manner. The use of AI develops faster than the authorities can make railings around its use.

It is even used to present evidence in court, said Grossman, and to provide impact declarations on the victims.

This year, a judge of a New York State Court of Appeal was furious after a plaintiff, representing himself, tried to use a younger and more beautiful avatar generated by AI to plead his case for him, reported CNN. It was quickly closed.

Despite the edifying stories that make headlines, Grossman and Charlotin consider AI as an incredibly useful tool for lawyers and they predict will be used more in court.

The rules on the best way to use AI differ from one jurisdiction to another. The judges have created their own standards, forcing lawyers and those who represent themselves before the court to submit DIFULGATIONS OF AI when it was used. In some cases, the judges of North Carolina, Ohio, Illinois and Montana have established various prohibitions on the use of AI in their audience rooms, according to a database created by the law firm ROPES & GRAY.

The American Bar Association, the national representative of the legal profession, published its first ethical directives on the use of AI last year. The organization warned that because these tools “are subject to errors, the non -critical dependence of lawyers with the content created by a [generative artificial intelligence] The tool can lead to inaccurate legal advice to customers or deceptive representations in the courts and third parties. “”

He continued: “Consequently, the dependence of a lawyer on the production of a gay tool – without an appropriate degree of independent verification or examination of his production – could violate the duty to provide a competent representation.”

The Consultative Committee for Rules of Proof, the group responsible for studying and recommending changes to the national rules of evidence of federal courts, has been slow to act and still works on changes to the use of AI for evidence.

In the meantime, Grossman has this suggestion for anyone uses AI: “Don’t trust – check everything.”
