Judge Catherine J. Pratt

Judge Catherine J. Pratt serves on the Los Angeles County Superior Court at the Stanley Mosk Courthouse, having been appointed by Governor Jerry Brown in November 2015 as part of a significant cohort of 25 judicial appointments statewide, seven of which were placed in Los Angeles County. Her appointment reflects the Brown administration's emphasis on diversifying the bench and selecting candidates with substantive civil litigation backgrounds. Judge Pratt's pre-bench career in civil litigation is the most significant data point available for predicting her judicial temperament and approach: attorneys who spent years in civil practice tend to have strong command of procedural rules, a practical orientation toward case management, and a lower tolerance for attorneys who are unprepared on the facts or the law. Because Judge Pratt trained at USC Gould School of Law, a rigorous institution with a strong emphasis on doctrinal precision and practical lawyering, it is reasonable to infer that she values well-structured legal arguments grounded in statutory text and case authority rather than policy advocacy untethered from doctrine. Her continued activity on the bench as noted in a May 2024 Daily Journal article suggests she remains an active and engaged jurist nearly a decade into her tenure, which typically correlates with developed and consistent courtroom practices. In the absence of analyzed rulings or attorney observations, this profile is necessarily inferential, drawing on appointment context, educational background, and career trajectory. Attorneys should treat all specific behavioral predictions as provisional and invest in gathering firsthand intelligence from colleagues who have appeared before her. The confidence level for this profile reflects the limited data currently available and should be updated as ruling analyses and practitioner observations are added.

Given Judge Pratt's background as a civil litigator before her appointment, attorneys should approach her courtroom with the assumption that she has seen most procedural maneuvers from both sides of the table. This means she is unlikely to be impressed by gamesmanship and is more likely to reward candor, efficiency, and thorough preparation. Civil litigators who become judges frequently have heightened sensitivity to discovery disputes and motion practice that appears designed to delay or harass rather than resolve genuine legal questions — attorneys should be prepared to justify the necessity and proportionality of any contested discovery or motion. For motion practice at Stanley Mosk, attorneys should ensure that all papers comply strictly with the California Rules of Court and the Los Angeles Superior Court Local Rules, as judges with civil litigation backgrounds tend to enforce procedural requirements rigorously. Oral argument should be used to address the judge's specific concerns rather than to re-argue the briefs — come prepared with a clear hierarchy of your strongest arguments and be ready to concede weaker points gracefully. Judges appointed from civil practice often appreciate when counsel acknowledges the strongest counterarguments and explains why they do not prevail. Because no ruling data is available, attorneys with upcoming appearances before Judge Pratt should proactively research her tentative ruling practices through the court's online portal, speak with colleagues who have appeared before her, and review any published opinions or Daily Journal coverage. Adapting quickly to her specific preferences once in the courtroom — and following up with research after each appearance — will build the most reliable picture of her judicial style.

  Interview Colleagues Who Have Appeared Before Her

  Because no attorney observation data is available in this profile, firsthand accounts from practitioners who have appeared before Judge Pratt are the most valuable intelligence source currently available. Specifically ask about her demeanor during oral argument, her approach to discovery disputes, and any known preferences regarding brief formatting or courtroom conduct.

  Ensure Full Compliance With Local Rules and Standing Orders

  Review the Stanley Mosk Courthouse's department-specific standing orders and any posted rules for Judge Pratt's department.

  Monitor Trellis and CourtListener for Emerging Ruling Data

  As this profile currently lacks ruling analyses, set up monitoring on Trellis, CourtListener, and similar platforms for any newly indexed rulings from Judge Pratt's department. Even a handful of rulings can reveal significant patterns in her approach to dispositive motions, evidentiary issues, and case management.

• ›Arrive early and be fully prepared before the matter is called — judges with civil litigation backgrounds have little patience for attorneys who are not ready to proceed when their case is called in a busy courthouse like Stanley Mosk.
• ›Address the court formally and avoid interrupting the judge; if she is asking a question, stop speaking immediately and listen carefully before responding — this is especially important given the inferential basis of this profile, as her specific preferences are unknown.
• ›Be concise and direct in oral argument; do not read from your briefs or repeat arguments already made in writing — assume the judge has read the papers and focus your argument on the dispositive issues or the judge's apparent concerns.
• ›If the court issues a tentative ruling, be prepared to either accept it or articulate specifically and respectfully why it should be reconsidered — avoid broad attacks on the tentative and instead identify the precise legal or factual point you believe warrants correction.
• ›Maintain professional courtesy toward opposing counsel at all times; judges who practiced civil litigation are acutely aware of when attorneys are being unnecessarily combative and may view it as a credibility issue.
