Judge Matthew G. Guerrero

Judge Matthew G. Guerrero has served on the San Luis Obispo County Superior Court since his appointment by Governor Jerry Brown in December 2017. The available public record documents two notable matters from his tenure: a December 2019 sentencing in which he imposed life in prison without the possibility of parole, and a 2021 case involving restitution for an employer defrauded by a job-seeker, the latter of which received coverage in the Metropolitan News-Enterprise. These two data points establish that Judge Guerrero handles both serious felony criminal matters and civil restitution disputes within San Luis Obispo County Superior Court. Because no ruling analyses, attorney observations, or ingested content are available at this time, the record does not support detailed characterizations of his judicial philosophy, preferred argument styles, or ruling tendencies. Attorneys should treat this profile as a foundational baseline and supplement it with direct research into San Luis Obispo County Superior Court dockets and local bar association resources before appearing before Judge Guerrero. What the record does confirm is that Judge Guerrero is a gubernatorial appointee with at least seven years on the bench as of 2024, and his docket has included high-stakes criminal sentencing as well as restitution matters. Attorneys in both criminal and civil contexts should prepare accordingly, recognizing that the court record reflects a judge willing to impose the most severe sentencing outcomes available under California law when the facts support it.

Given that the only criminal sentencing data point on record is a life-without-parole sentence, defense attorneys in serious felony matters before Judge Guerrero should approach sentencing hearings with thorough mitigation packages. The record does not reveal whether mitigating arguments influenced or were rejected in that case, but the severity of the outcome underscores the importance of leaving nothing to chance in pre-sentencing preparation. Prosecutors should recognize that Judge Guerrero has demonstrated willingness to impose the maximum available sentence when the record supports it. For civil and restitution matters, the 2021 employer-fraud restitution case indicates Judge Guerrero has handled disputes involving financial harm and victim compensation. Attorneys in restitution proceedings should arrive with precise, documented calculations of loss and be prepared to address the factual basis for any restitution figure with specificity. The fact that this case drew Metropolitan News-Enterprise coverage suggests it involved a legally notable or contested issue, so thorough briefing on restitution law and supporting authority is warranted. Because no attorney observations or behavioral data are available, attorneys should consult with local San Luis Obispo County practitioners who have appeared before Judge Guerrero to obtain current, firsthand intelligence on courtroom preferences, scheduling practices, and procedural expectations before any significant hearing.
