CHICAGO, ILLINOIS, JUL 15 – Goldberg Segalla's use of ChatGPT led to fabricated legal citations in a Chicago Housing Authority case, prompting firm-wide AI policy reforms and court sanctions.
- On July 17, 2025, lawyers for the Chicago Housing Authority used ChatGPT to cite a nonexistent court case in a lead paint lawsuit motion at the Daley Center.
