A.I. 'Hallucinations' Created Errors in Court Filing, Top Law Firm Says

Source: NYT

An elite Wall Street law firm has apologized to a federal judge for submitting a court filing replete with errors created by artificial intelligence, including “hallucinations” that fabricated case citations.

The A.I.-generated errors came in a recent motion in U.S. Bankruptcy Court in Manhattan and were discovered by lawyers from an opposing firm, Andrew Dietderich, a partner at Sullivan & Cromwell, wrote in a letter to Judge Martin Glenn on April 18.

The firm provided a ledger of the errors, which spanned three pages and totaled around three dozen. A number of them involved the citation of seemingly imagined passages from real cases. Some were clerical errors that the firm said were not A.I.-related.

Sullivan & Cromwell is one of the oldest and most prestigious law firms in the country. It is representing President Trump in several appeals, including his criminal conviction in 2024 in a case that stemmed from a hush-money payment to a porn star. Jay Clayton, now the U.S. attorney for the Southern District of New York, was of counsel and formerly a partner at the firm.

I also wonder if AI research was an approved option, or if an associate or two had used it to rapidly 'catch up' on their workload.

I wouldn't be surprised if some professional heads rolled at the firm for this.

Who judges this "prestige"? On top of working for the worst criminal in the country, they are telling lies in court, thanks to being too lazy to check the computer-generated work that a "prestigious" firm ought to be doing itself.

If I enter 2+2 into a calculator, and it gives me 18, that's not a hallucination, or any other mental event. It is a data processing error.

Stop giving agency to these shitty technologies, New York Times.
