Judge Maria Lucy Armendariz

Judge Maria Lucy Armendariz sits at the Stanley Mosk Courthouse in Los Angeles County, having been elected to the Los Angeles Superior Court in the June 2018 primary and formally appointed in October 2018. Her pre-bench career included service as both an Administrative Law Judge (ALJ) and as a prosecutor, giving her a dual perspective on adjudication and enforcement that informs her work on the bench. She has been recognized by the Glendale Latino Association and is active in community and judicial programs in the Los Angeles area. Judge Armendariz has been publicly associated with a Los Angeles criminal court program that diverts mentally ill offenders from prosecution, as reported by the Los Angeles Times in May 2023. She also presided over the case involving Los Angeles Rams cornerback Derion Kendrick, which was paused for judicial diversion, as reported by the Los Angeles Times in December 2023. These two documented instances establish a concrete pattern of engagement with diversion-based and alternative criminal justice approaches. The available data is limited to biographical and career profile information, with no analyzed rulings or attorney observations on record. Attorneys should treat the insights below as grounded in verified public record data but should conduct additional research before drawing firm conclusions about her courtroom preferences or ruling tendencies.

Given Judge Armendariz's documented involvement with diversion programs — both for mentally ill offenders and for judicial diversion in higher-profile criminal cases — defense attorneys in criminal matters should be prepared to present thorough diversion eligibility arguments. Where a client meets statutory criteria for judicial diversion or mental health diversion under Penal Code sections 1001.36 or 1001.95, counsel should arrive with complete supporting documentation, including mental health evaluations, treatment plans, and program availability, as the judge has demonstrated willingness to engage with these mechanisms. Her background as a former prosecutor means she is familiar with the evidentiary standards and procedural posture of the People's case. Defense attorneys should not underestimate her knowledge of prosecutorial strategy, and prosecutors should not assume a sympathetic ear simply because of her prior role. Her ALJ background further suggests comfort with administrative records, structured hearings, and procedural rigor. Attorneys on both sides should be precise and organized in their presentations. Because no ruling analyses or attorney observations are available, attorneys should supplement this profile with direct research into her recent docket and, where possible, speak with colleagues who have appeared before her. The patterns identified here are drawn from public reporting and profile data only.
