Judge Thomas J. Griego

Judge Thomas J. Griego has served on the Los Angeles County Superior Court since his election on November 4, 2014, following a prior unsuccessful judicial bid in 2009. His pre-bench career spans approximately twenty years as a Deputy City Attorney with the Los Angeles City Attorney's Office, where he prosecuted matters involving manslaughter, sexual battery, racial discrimination, and gang-related crimes, including service in the Anti-Gang Division beginning in 2011. Before joining the City Attorney's Office in 1994, he served as Chief of Staff for a Los Angeles City Councilman, worked as an associate at a private law firm, and maintained a brief private practice. His legal education was completed at Whittier College School of Law in 1990, and he holds an undergraduate degree in Political Science from UCLA. The most significant documented fact about Judge Griego's conduct on the bench is a public admonishment issued by the California Commission on Judicial Performance in July 2024. The admonishment, reported by both the Metropolitan News-Enterprise and the Daily Journal, arose from his treatment of self-represented (pro per) litigants. A CJP public admonishment is a formal disciplinary action, representing a finding by the Commission that the judge engaged in conduct warranting official censure. This is the single most consequential data point available about his judicial temperament and courtroom conduct. No ruling analyses, attorney observations, or ingested content are available at this time, which limits the depth of pattern analysis that can be offered. The profile data drawn from court records, State Bar records, and public reporting provides a factual foundation for understanding his background and the one documented disciplinary matter, but attorneys should supplement this intelligence with direct courtroom observation and peer consultation before high-stakes appearances.

Given Judge Griego's documented CJP admonishment specifically tied to his treatment of self-represented litigants, attorneys who represent clients against pro per parties should be alert to the possibility that the court may be operating under heightened scrutiny of its own conduct in those situations following the 2024 admonishment. Attorneys should not exploit any procedural disadvantage a pro per opponent faces in ways that could draw judicial frustration; instead, maintain professional courtesy toward all parties and allow the court to manage pro per litigants without prompting. Judge Griego's prosecutorial background — approximately twenty years handling criminal matters including gang crimes, manslaughter, and sexual battery — reflects a career built on adversarial, fact-intensive litigation in a government enforcement context. Attorneys appearing before him on civil matters should present facts clearly and concisely, as his professional formation emphasized evidence-based argument rather than abstract legal theory. His government service background also suggests familiarity with procedural rigor and institutional processes. Because no ruling analyses or attorney observations are available, attorneys cannot rely on established pattern data for motion practice preferences, tentative ruling habits, or oral argument style. Direct courtroom observation prior to a contested hearing, and consultation with attorneys who have recently appeared before Judge Griego, are essential steps before any significant appearance. Do not assume his conduct in any given hearing will mirror or deviate from the CJP admonishment incident without independent verification.

  Prepare Fact-Centered, Evidence-Based Briefs

  Given his two-decade background as a criminal prosecutor handling evidence-intensive matters, structure arguments around clear factual records and direct legal authority rather than abstract or policy-based reasoning.

• ›Treat all parties, including self-represented litigants, with visible professional courtesy in open court; the CJP admonishment record makes this courtroom particularly sensitive to how parties and counsel interact with pro per litigants.
• ›Do not attempt to leverage a pro per opponent's procedural inexperience in ways that could draw attention or require judicial intervention; allow the court to manage those dynamics independently.
• ›Present arguments in a structured, fact-first format consistent with the evidentiary and prosecutorial framework that defined Judge Griego's pre-bench career.
• ›Be fully prepared on procedural requirements; his government litigation background reflects familiarity with institutional procedure and compliance expectations.
