Judge Kristi Peariso

Judge Kristi Peariso has served on the Ventura County Superior Court bench since her appointment in March 2022, following a career as a practicing attorney in Camarillo, California. Her docket, as documented in news coverage spanning 2022 through 2025, reflects a consistent assignment to serious criminal matters, including double-murder proceedings, homicide cases, and competency hearing proceedings. This concentration in high-stakes criminal litigation distinguishes her as a judge with substantial exposure to complex procedural and substantive criminal law issues early in her tenure. The available data establishes that Judge Peariso has handled multi-defendant and multi-charge criminal cases, including a double-murder case involving defendant Alvin Johnson in September 2024 and a murder case with competency hearing proceedings involving a Newbury Park defendant in December 2024. These case types demand rigorous command of California Penal Code provisions, evidentiary standards in criminal proceedings, and mental competency statutes under Penal Code section 1368 et seq. Her active management of competency hearings signals familiarity with the intersection of criminal procedure and mental health law. Because no ruling analyses or attorney observations are available in the current dataset, specific patterns regarding her evidentiary rulings, sentencing philosophy, or courtroom management style cannot be established from the data. Attorneys should treat the guidance below as grounded in her documented case assignments and appointment background, not in observed ruling outcomes.

Given Judge Peariso's documented focus on serious felony criminal matters — including murder, double-murder, and competency proceedings — attorneys appearing before her should arrive with thorough command of California criminal procedure, particularly as it relates to homicide charges and mental competency statutes. Competency hearings under Penal Code section 1368 require precise procedural compliance, and her documented handling of such proceedings indicates she engages with these issues substantively. Because Judge Peariso was appointed in March 2022 and her pre-bench career was as a practicing attorney in Camarillo, attorneys should not assume a prosecutorial or exclusively defense-side background shapes her rulings — the data does not specify her prior practice area. Preparation should be thorough and neutral in framing, with arguments grounded in statutory authority and case law rather than assumptions about her prior professional sympathies. With no attorney observations or ruling analyses in the dataset, attorneys cannot rely on established patterns for motion practice, evidentiary preferences, or courtroom temperament. The prudent approach is to treat every appearance as requiring comprehensive preparation, clear written submissions, and strict procedural compliance, particularly given the gravity of the criminal matters she routinely handles.
