Judge Armen Tamzarian

Judge Armen Tamzarian was appointed to the Los Angeles County Superior Court by Governor Jerry Brown on December 5, 2013. In 2025, he was appointed to the California Court of Appeal in Los Angeles, with that appointment confirmed by the Commission on Judicial Appointments. His tenure at the Superior Court spans over a decade, reflecting a sustained career on the bench in Los Angeles County. The available public record documents one notable appellate posture: in October 2025, Judge Tamzarian expressed skepticism toward a legal challenge to the Los Angeles 'Mansion Tax' while sitting as a California Appeals Court judge. This single documented instance indicates a willingness to scrutinize challenges to local tax policy measures, though no broader pattern of rulings is available from the Superior Court record to characterize his judicial philosophy in depth. Given the transition to the Court of Appeal, attorneys who previously appeared before Judge Tamzarian at Stanley Mosk Courthouse should be aware that his active docket is now at the appellate level. The data available is limited to biographical and appointment records, and no ruling analyses or attorney observations are on file. Assessments of his courtroom style, preferred argument formats, or ruling tendencies at the trial court level cannot be made from the current data set.

The only documented substantive judicial signal available is Judge Tamzarian's reported skepticism toward a challenge to the Los Angeles Mansion Tax at the appellate level in October 2025. For attorneys handling local tax policy matters or municipal ordinance challenges before him, this record suggests that arguments attacking the validity of locally enacted tax measures face a skeptical bench. Attorneys advancing such challenges should prepare to address the legal basis for the ordinance with precision and anticipate pointed questioning. Because no trial court ruling analyses, motion outcomes, or attorney observations are available in the current data set, attorneys cannot rely on documented patterns regarding his preferences for oral argument, briefing style, evidentiary standards, or case management. Preparation should therefore focus on standard best practices for Los Angeles Superior Court appearances while seeking current intelligence from colleagues who have appeared before him recently. Given his elevation to the Court of Appeal in 2025, attorneys with matters still assigned to him at Stanley Mosk Courthouse should confirm current case assignment status and verify whether their matter has been reassigned as part of his transition to the appellate bench.

• ›Confirm the correct courthouse and courtroom before appearance, given Judge Tamzarian's transition from Stanley Mosk Courthouse to the California Court of Appeal in 2025.
