Judge Christopher K. Lui

Judge Christopher K. Lui of the Los Angeles County Superior Court at Stanley Mosk Courthouse brings an unusually sophisticated federal and white-collar litigation background to the state bench. Appointed by Governor Jerry Brown in August 2014, he arrived with a career arc that moved from a federal clerkship under Hon. Dickran Tevrizian, through complex commercial litigation at O'Melveny & Myers, to federal prosecution at the U.S. Attorney's Office where he coordinated the Medicare Fraud Strike Force, and finally to partnership at Crowell & Moring. This trajectory signals a judge who is deeply comfortable with procedurally complex, document-intensive litigation and who has internalized the rigorous standards of federal practice — including precise pleading, evidentiary discipline, and structured case management. The notable cases on his docket — a default judgment against a high-profile private school, a malicious prosecution finding against a plaintiffs' firm, and a ruling favoring the Archdiocese in a workplace misconduct case — suggest a judge who is willing to make difficult, potentially unpopular rulings when the law and facts support them. His recognition for 'setting trials up for success through thorough preparation' indicates an active judicial manager who expects counsel to match his level of preparation. His docket spans torts, labor and employment, commercial, consumer, property, and insurance matters, reflecting the broad civil jurisdiction typical of a Mosk complex or general civil department. With no party preference registration and a career that included both private defense work and federal prosecution, Judge Lui is unlikely to be ideologically predictable. Attorneys should expect a judge who rewards precision, penalizes sloppiness, and approaches cases with the analytical rigor of a former federal litigator. His CJP record is noted but no public discipline appears to have resulted, and its significance remains unclear without further detail.

Attorneys appearing before Judge Lui should lead with federal-quality briefing. His years at O'Melveny & Myers handling complex commercial and class action defense, followed by federal prosecution, mean he has seen the best and worst of litigation practice at a high level. Briefs should be tightly organized, cite controlling authority precisely, and avoid rhetorical padding. He is likely to have read the papers thoroughly before any hearing, so oral argument should be used to address the court's specific concerns rather than to re-summarize the brief. Counsel who walk in and recite their papers risk losing credibility quickly. Given his case management philosophy — described as setting trials up for success through thorough preparation — attorneys should expect active engagement at CMCs and trial-setting conferences. Come prepared with realistic trial estimates, a clear theory of the case, and a concrete discovery plan. Judges with this background tend to impose tight deadlines and hold parties to them. On evidentiary matters, expect a judge who understands the Federal Rules of Evidence and will apply California's analog rules with similar rigor; foundation, hearsay, and authentication objections will be taken seriously. In cases involving fraud, white-collar conduct, or complex financial claims, Judge Lui's prosecutorial and defense background gives him a sophisticated lens. Oversimplifying complex financial schemes or understating the legal elements of fraud-based claims is likely to draw skepticism. Conversely, attorneys who can present complex factual records in a clean, structured narrative — as one would before a federal judge — are likely to earn credibility. His malicious prosecution ruling against a plaintiffs' firm also signals that he will not hesitate to scrutinize litigation conduct itself.

  Prepare Federal-Standard Briefs

  Given Judge Lui's federal clerkship, AUSA experience, and BigLaw background, all motion papers should meet federal court quality standards: precise citations, clean structure, no rhetorical filler, and thorough engagement with adverse authority. Sloppy or conclusory briefing will likely be noticed and penalized.

  Audit Pre-Filing Investigation for Any Fraud or Tort Claims

  In light of the malicious prosecution ruling against the Dominguez Firm, ensure that any complaint filed before Judge Lui — particularly in tort or fraud matters — is supported by a documented pre-filing investigation. Be prepared to defend the factual basis for each cause of action if challenged.

  Develop a Detailed Case Management Plan

  Prepare a realistic and specific case management proposal for CMCs, including discovery phasing, expert timelines, and a trial estimate. Judge Lui's preparation-focused philosophy suggests he will engage actively with scheduling and hold parties to agreed timelines.

  Research Any Publicly Available Rulings from His Department

  No ruling analyses were available for this profile. Attorneys should independently research Trellis, CourtListener, and the court's own docket for recent tentative rulings and final orders from Judge Lui's department to identify any emerging patterns in motion practice, evidentiary rulings, or discovery disputes.

  Prepare for Substantive Oral Argument

  Do not plan to use oral argument to summarize your brief. Judge Lui is likely to have read the papers. Prepare to address the weakest points in your own position, anticipate the court's likely concerns, and be ready to engage in a genuine dialogue about the legal and factual issues.

  Review CJP Record for Public Information

  A CJP record is noted in the profile. Attorneys should check the Commission on Judicial Performance's public database to determine whether any public admonishment or other public record exists, which could provide insight into judicial temperament or conduct issues.

• ›Arrive fully prepared and on time — Judge Lui's preparation-focused reputation suggests he has little patience for counsel who have not read the file or are unfamiliar with their own case details.
• ›Do not recite your brief during oral argument; instead, engage directly with the court's questions and focus on the dispositive legal or factual issues the judge is most likely to find determinative.
• ›Maintain professional decorum at all times, particularly in adversarial exchanges — a judge with a prosecutorial background will be attuned to credibility and will notice counsel who overreach or mischaracterize the record.
• ›Be precise with citations and record references; if you cite a case or a document, be prepared to provide the exact cite on the spot, as a former federal litigator will expect accuracy.
• ›Treat case management conferences as substantive hearings, not formalities — come with a prepared schedule, realistic estimates, and a clear litigation roadmap.
• ›If you are the plaintiff's attorney, be prepared to articulate the factual basis for each claim concisely and defensibly, given the court's demonstrated willingness to scrutinize litigation conduct.
