Judge David S. Cunningham III

Judge David S. Cunningham III has served on the Los Angeles County Superior Court since his 2009 appointment by Governor Arnold Schwarzenegger, bringing to the bench a sophisticated and varied pre-judicial career that spans federal court clerking, BigLaw practice, boutique litigation, and public service leadership. His educational pedigree — summa cum laude economics from USC and a J.D. from NYU Law School — signals a judge comfortable with quantitative reasoning, economic analysis, and rigorous legal argumentation. His clerkship under U.S. District Judge Terry J. Hatter, Jr. in the Central District of California likely instilled federal-court-level expectations for procedural precision, well-organized briefing, and substantive legal analysis over rhetorical flourish. Cunningham's pre-bench career is notably eclectic: he moved through large national firms, a labor and employment specialty shop (Jackson Lewis), a municipal law firm (Meyers Nave), and served as President of the Los Angeles Police Commission from 2001 to 2005. This background suggests familiarity with employment law, civil rights, municipal liability, and complex commercial disputes. His docket has reportedly included privacy matters, toxic tort litigation, and entertainment law — areas that demand careful management of expert testimony, voluminous discovery, and nuanced damages analysis. The 2023 mesothelioma/Avon appellate reversal noted in his profile suggests at least one instance where a ruling drew appellate scrutiny, a data point attorneys should investigate further. As of a March 2026 news item, Judge Cunningham announced his retirement from the court. Attorneys with pending matters should confirm his current assignment status and any transition of cases. With no analyzed rulings or attorney observations in the current dataset, assessments are necessarily inference-based from career and biographical data, and should be supplemented with independent research into his recent docket.

Given Judge Cunningham's federal clerkship background, attorneys should approach his courtroom with the discipline expected in federal practice: tight, well-organized briefs with clear roadmaps, precise citations, and honest acknowledgment of adverse authority. Judges who clerked in federal court frequently have lower tolerance for state-court habits such as excessive boilerplate, inflated page counts, and citation-heavy arguments that substitute volume for analysis. Lead with your strongest legal argument, not your most sympathetic fact, and ensure your papers are internally consistent. Cunningham's Jackson Lewis background in labor and employment law means he likely has sophisticated instincts about wage-and-hour claims, discrimination frameworks, and employer-side defenses. In employment matters, do not assume he will be sympathetic to either side based on his firm history alone — his Police Commission leadership also reflects a public-interest orientation. In complex civil matters involving experts (toxic tort, privacy, entertainment damages), be prepared to defend your expert's methodology rigorously; his economics training suggests he will probe damages models and causation chains more carefully than a generalist judge might. With his announced retirement, there is an elevated risk of case reassignment mid-litigation. Attorneys should proactively confirm the status of any pending matters, ensure all deadlines are calendared independently of court notices, and be prepared to re-introduce case context to a successor judge. If appearing before him in his final months, expect a judge who may be managing a winding-down docket and potentially less inclined toward lengthy continuances.

  Verify Current Case Assignment and Retirement Status

  Before any filing or appearance, confirm whether Judge Cunningham is still actively assigned to your case given his announced March 2026 retirement. Check the court's online docket and contact the clerk's office directly. A reassignment mid-case requires immediate strategic adjustment.

  Research the 2023 Mesothelioma/Avon Appellate Reversal

  Identify the specific case and the legal basis for the appellate reversal. Understanding what the Court of Appeal found deficient in his ruling will reveal potential blind spots or tendencies in how he handles expert causation, product liability, or damages in toxic tort matters — and may be relevant to any similar case before him.

• critical

  Prepare Federal-Quality Briefs and Motions

  Given his federal clerkship background, draft all papers to federal district court standards: clear statement of issues, organized argument headings, honest treatment of adverse authority, and tight citation form. Avoid state-court habits of excessive recitation of procedural history or padding.

• important

  Develop Rigorous Expert and Damages Frameworks

  For any case involving expert testimony or damages calculations, prepare to defend methodology at a sophisticated level. His economics training means he will likely probe the assumptions underlying damages models. Prepare your expert for detailed Sargon/Daubert-style questioning even in state court proceedings.

• important

  Research His Employment Law Rulings Independently

  Given his Jackson Lewis background, independently research any available rulings in employment matters on his docket through Trellis or the court's own system. Determine whether his management-side background has translated into any discernible patterns in how he rules on class certification, arbitration enforcement, or summary judgment in employment cases.

  Prepare a Concise Case Status Summary for Potential New Judge

  Given the retirement announcement, prepare a clear, neutral case status summary document that could be submitted to a successor judge. This should include procedural history, key prior rulings, pending motions, and upcoming deadlines — enabling a smooth transition and protecting your client's interests regardless of reassignment.

• ›Arrive fully prepared on procedural and substantive issues; his federal clerkship background suggests he expects attorneys to know their cases cold and will not appreciate requests for basic continuances due to lack of preparation.
• ›Address the court with formal federal-court-level decorum; given his clerkship and BigLaw background, casual or overly familiar courtroom behavior is likely to register negatively.
• ›Be prepared to engage directly on economic and quantitative arguments; do not present damages figures or statistical evidence without being able to explain the underlying methodology in plain terms.
• ›Acknowledge adverse authority proactively rather than waiting for the court to raise it; judges with federal clerkship experience typically view candor about adverse precedent as a marker of credibility.
• ›Keep oral argument focused and organized with a clear roadmap; given his economics and analytical background, structured, logical presentations will be more persuasive than narrative or emotional appeals.
• ›Ensure all meet-and-confer obligations are fully documented and completed before filing discovery motions; his professional background suggests low tolerance for discovery disputes that could have been resolved through good-faith conferral.
