Gov. Jerry Brown swore in Justice Joshua Groban to the California Supreme Court in Sacramento, at a ceremony joined by Chief Justice Tani Cantil-Sakauye and other judicial and state officials.

Groban’s nomination to the court was unanimously confirmed by the Commission on Judicial Appointments on Dec. 21. As senior advisor to the governor, Groban, 45, of Los Angeles, oversaw the appointment of 644 judges throughout the state since 2011. These appointments have been lauded as the most diverse in the state’s history.

Groban also advised the governor in high-profile litigation and policy issues involving education, the judiciary, criminal justice, national security and constitutional interpretation. He was legal counsel for the Jerry Brown for Governor Campaign in 2010 and an attorney at Munger, Tolles and Olson LLP from 2005-10 and at Paul, Weiss, Rifkind, Wharton and Garrison LLP from 1999 to 2005. Groban served as a law clerk for the Honorable William C. Conner at the U.S. District Court, Southern District of New York from 1998-99. He has been a lecturer in state appellate practice at the University of California, Los Angeles School of Law since 2015. Groban earned a Juris Doctor degree from Harvard Law School, where he graduated cum laude and a Bachelor of Arts degree from Stanford University, where he graduated with honors and distinction.

Brown also released the final applicant and appointee data for the administration’s judicial appointments. Since taking office in 2011, Brown has appointed 644 judges, including 193 from 2018 through Jan. 2.

Last year, women accounted for more than half of Brown’s judicial appointees and nearly 6 percent of all appointees identified themselves as LGBT. Forty-one percent of all appointees identified themselves as non-white or other/unknown.
