The firm frequently appears at the top of various industry rankings.

Pro bono work[edit]

Sidley Austin partner George Fatheree worked pro bono on behalf of the descendants of Willa and Charles Bruce[33] to execute the return of beachfront land which had been seized by Los Angeles authorities in the 1920s.[34] The couple had lost the property, known as Bruce's Beach, when the state claimed it for public use and sold it to private investors.[35] It was officially restored to the couple's great grandsons, Marcus and Derrick Bruce, on July 20, 2022. The effort involved more than 1,000 hours of pro bono work.[36]
