Judge Sophia Choi

Judge Sophia Choi was appointed to the Riverside Superior Court by Governor Gavin Newsom on March 13, 2024, making her one of the newer members of the bench at the Riverside Historic Courthouse. Her entire pre-bench legal career was spent as a prosecutor at the Riverside County District Attorney's Office, where she began as a Deputy District Attorney in 2020 and was elevated to Senior Deputy District Attorney in 2023. This prosecutorial background is the defining feature of her professional formation as a lawyer. Because Judge Choi's career was exclusively in criminal prosecution at the Riverside County DA's Office, attorneys should understand that her legal training and courtroom experience were built entirely within that framework. She received her law degree from Southwestern Law School. No ruling analyses, attorney observations, or courtroom behavior data are currently available for Judge Choi, as she was appointed only in early 2024. Given the very limited data available, attorneys should approach appearances before Judge Choi with the understanding that she is a newly appointed judge with a singular background in criminal prosecution. No patterns in civil, family, or other practice areas can be drawn from the available data. Practitioners should conduct fresh research and monitor her rulings as her record develops on the bench.

Judge Choi's background is exclusively in criminal prosecution, having spent her entire legal career at the Riverside County District Attorney's Office. Attorneys appearing before her in criminal matters should be aware that she has direct, hands-on experience with the prosecutorial perspective, including case evaluation, charging decisions, and courtroom advocacy from the People's side. Defense attorneys in particular should be precise and well-prepared, as Judge Choi will be familiar with prosecutorial arguments and strategies. For attorneys appearing in civil, family law, or other non-criminal matters, there is no available data from which to draw strategic guidance specific to those practice areas. The absence of ruling analyses means attorneys cannot rely on established patterns and should treat each appearance as an opportunity to establish a strong first impression with a judge who is still developing her judicial record. As a newly appointed judge (appointed March 2024), Judge Choi is in the early stages of building her judicial identity. Attorneys should prioritize clear, well-organized presentations, thorough citation of authority, and strict compliance with local rules and court procedures. Demonstrating respect for the court's time and procedures is especially important when appearing before a judge who is still establishing courtroom norms.
