Judge Robert Serna

Judge Robert Serna serves on the Los Angeles Superior Court at the Stanley Mosk Courthouse, having been appointed by Governor Jerry Brown in October 2018. His appointment followed his election in the June 2018 primary, as reported by the Metropolitan News-Enterprise. He received his legal education at Loyola Law School. The available public record documents Judge Serna presiding over serious felony matters, including a high-profile murder trial in which an ex-convict was convicted of killing a homeless woman in an Irwindale riverbed with a pickaxe. That verdict was reported in September 2025, and the defendant was subsequently sentenced to life in prison in November 2025. The record also references a Glendora sexual case, though details are incomplete in the available data. These cases establish that Judge Serna has handled serious violent felony matters at the trial level. Because no analyzed rulings, attorney observations, or ingested content are available for this judge, no patterns regarding his procedural preferences, motion practice tendencies, evidentiary rulings, or courtroom management style can be stated with confidence. Attorneys should treat the guidance below as baseline professional preparation rather than judge-specific behavioral intelligence, and should actively seek firsthand accounts from colleagues who have appeared before Judge Serna.

Given the absence of ruling analyses and attorney observations, no data-supported conclusions about Judge Serna's preferred argument styles, motion practice tendencies, or courtroom demeanor are available. Attorneys should not assume any particular approach will be favored or disfavored based on this profile alone. What the record does confirm is that Judge Serna has presided over serious violent felony trials through verdict and sentencing, demonstrating experience managing complex, high-stakes criminal proceedings. Attorneys in criminal matters should be prepared for a judge with demonstrated exposure to serious felony litigation, including cases involving vulnerable victims and significant sentencing consequences. Attorneys appearing before Judge Serna in any matter should consult the Los Angeles Superior Court's local rules and standing orders, review any department-specific procedures posted for his courtroom, and seek direct accounts from practitioners who have recently appeared before him. These steps are the most reliable path to actionable preparation given the current data limitations.
