Two years after prosecutors charged Sidley Austin real estate partner Stanley Stallworth with sexually assaulting an 18-year-old man, a judge in Chicago has found Stallworth not guilty.

Stanley Stallworth, 52, joined Sidley Austin in 1990 and worked in the firm’s Chicago office. He withdrew from the partnership after he was criminally charged in December 2013 and is now retired from the firm, according to Sidley Austin executive committee chairman Carter Phillips. The firm declined to comment on Stallworth’s case.
