Lawyers hired by the Chicago Housing Authority recently cited Illinois Supreme Court case Mack v. Anderson in an effort to persuade a judge to reconsider a jury’s $24 million verdict against the agency in a case involving the alleged poisoning of two children by lead paint in CHA-owned property.
In the latest headache for CHA , law firm Goldberg Segalla used artificial intelligence, specifically ChatGPT, in a post-trial motion and neglected to check its work, court records show. A jury decided in January , after a roughly seven-week trial, that CHA must pay more than $24 million to two residents who sued on behalf of their children, finding the agency responsible for the children’s injuries, including past and future damages.
“An exhaustive investigation revealed that one attorney, in direct violation of Goldberg Segalla’s AI use policy, used AI technology and failed to verify the AI citation before including the case and surrounding sentence describing its fictitious holding,” said Goldberg Segalla’s lead counsel in the case, Larry Mason, in the filing.
Mason, whom the judge admonished for shouting during closing arguments in January, noted that “several contributors” supported him while preparing the motion. He also said in the filing that the investigation found “no intent to deceive the Court” and no other attorneys at the firm were aware of the improper citation.
