Judge Kevin R. Murphy

Judge Kevin R. Murphy serves on the Marin Superior Court, having been appointed by Governor Gavin Newsom on December 7, 2023. As a Newsom appointee, Judge Murphy joined the bench through the gubernatorial appointment process rather than through election, which places his initial tenure in the context of a Democratic administration's judicial selection priorities. His appointment is recent, meaning his judicial record on the Marin bench is still developing and limited public ruling data is currently available. Of note, Judge Murphy has a record with the Commission on Judicial Performance (CJP). The existence of a CJP record is a material fact attorneys should investigate directly through the CJP's public disclosure database before appearing before this judge. CJP records can range from advisory letters to formal discipline, and the nature and outcome of any such record is directly relevant to understanding the judge's conduct history on the bench. Given the recency of his appointment and the absence of analyzed rulings or attorney observations in the available data, no ruling patterns, procedural preferences, or courtroom tendencies can be established from the current record. Attorneys appearing before Judge Murphy should conduct independent research into any CJP disclosures and monitor emerging case law from his courtroom as his record develops.

Because no ruling analyses or attorney observations are available, attorneys cannot rely on established behavioral patterns when preparing for appearances before Judge Murphy. The most prudent approach is to treat each appearance as an opportunity to establish a strong first impression with a judge whose preferences and tendencies are not yet documented in the public record. Thorough preparation, clear written submissions, and professional courtroom conduct are the baseline expectations for any Marin Superior Court appearance. Attorneys should proactively research Judge Murphy's CJP record through the Commission on Judicial Performance's official public database before any significant appearance. Understanding the nature and resolution of any CJP matter is a due diligence step that could inform how counsel frames procedural or substantive arguments, and whether any recusal considerations are warranted. Given that Judge Murphy was appointed in late 2023, he is still in the early phase of his judicial tenure. Attorneys who appear before newer judges benefit from presenting well-organized, clearly structured briefs and oral arguments that do not assume familiarity with local litigation customs. Citing applicable Marin Superior Court local rules explicitly in filings is advisable.
