Judge Chrishna M. Martinez

Judge Chrishna M. Martinez is a newly appointed jurist to the San Joaquin Superior Court, having been appointed by Governor Gavin Newsom on March 12, 2024, filling the vacancy left by the retirement of Judge Bernard J. Garber. Her appointment is notable for the depth of her public defense background: she spent approximately 25 years as a Deputy Public Defender at the San Joaquin County Public Defender's Office, beginning in 1999. This extensive career on the defense side of criminal proceedings is the single most defining characteristic of her pre-bench experience and will almost certainly shape her judicial temperament, her sensitivity to due process concerns, and her familiarity with the practical realities faced by criminal defendants and their counsel. Because Judge Martinez was appointed in early 2024 and no ruling analyses, attorney observations, or ingested content are currently available, her judicial philosophy must be inferred from her career trajectory and educational background. She earned her J.D. from the University of California, Davis School of Law, an institution known for its public interest and social justice orientation in legal education. Combined with her quarter-century in public defense, this suggests a judge who is likely attuned to issues of indigent representation, prosecutorial conduct, evidentiary fairness, and the constitutional rights of defendants. Attorneys should not assume, however, that her defense background translates into automatic rulings favoring defendants — judges frequently work to demonstrate impartiality precisely because of their prior advocacy roles. As a brand-new judge in San Joaquin County, Judge Martinez is still establishing her courtroom norms, procedural preferences, and ruling patterns. This creates both uncertainty and opportunity for attorneys who appear before her early in her tenure. Practitioners who engage respectfully, demonstrate procedural precision, and present well-organized arguments grounded in California law are likely to make favorable impressions during this formative period on the bench.

Given Judge Martinez's 25-year career as a Deputy Public Defender, attorneys on both sides of criminal matters should anticipate a judge with granular, practical knowledge of criminal procedure, discovery obligations, and the mechanics of public defense. Prosecutors appearing before her should be especially meticulous about Brady and Pitchess compliance, as she will likely recognize discovery deficiencies that a judge without defense experience might overlook. Defense attorneys should not assume favoritism, but can expect a judge who understands the resource constraints of public defenders and the real-world pressures on defendants — arguments grounded in those realities may resonate. For civil practitioners, the lack of any ruling history means you are working with a blank slate. The safest approach is to treat every appearance as a first impression: arrive over-prepared, cite California authority precisely, and do not assume familiarity with your case. Because she is newly appointed, Judge Martinez may be more reliant on well-briefed motions and thorough oral argument than a more seasoned judge who can draw on years of pattern recognition. Invest heavily in your written submissions — clear, logically structured briefs with strong California case citations will carry significant weight. Strategically, attorneys should monitor early rulings and local bar association feedback as her tenure develops. Being among the first practitioners to appear before her and conducting yourself professionally may establish goodwill. Avoid aggressive or dismissive courtroom tactics; a judge who spent decades advocating for marginalized clients is unlikely to respond well to condescension or procedural gamesmanship. Collaborative, solution-oriented advocacy is likely to be better received than combative posturing.

  Verify Current Courtroom Procedures Directly

  Because Judge Martinez is newly appointed and no courtroom-specific procedural preferences are documented, contact her clerk or check the San Joaquin Superior Court website for any standing orders, tentative ruling procedures, or scheduling requirements specific to her department before any appearance.

  Audit Discovery Compliance Thoroughly in Criminal Matters

  For any criminal case, conduct a rigorous internal audit of all discovery obligations — Brady, Giglio, Pitchess — before appearing. Judge Martinez's public defender background means she will likely identify deficiencies that less experienced judges might miss. This is especially critical for prosecution teams.

  Prepare Comprehensive Written Briefs

  With no established ruling pattern to rely on, well-crafted written submissions are your best tool for shaping outcomes. Invest in clear, logically organized briefs with precise California statutory and case citations. Do not rely on oral argument alone to fill gaps in your written work.

  Research Judge Garber's Prior Courtroom Norms as Baseline

  Judge Martinez fills the vacancy of Judge Bernard J. Garber. Researching Garber's former courtroom procedures and local bar feedback may provide a partial baseline for what the department's administrative expectations look like, even if her judicial philosophy differs.

  Prepare Constitutional and Due Process Arguments Fully

  Given her public defense background, any constitutional or due process arguments should be fully developed and not treated as secondary. Brief these issues thoroughly even if you believe the court may not reach them — she is more likely than average to engage with them substantively.

  Monitor Local Bar Association Feedback on Her Rulings

  As her tenure develops, San Joaquin County Bar Association members and criminal defense bar practitioners will begin sharing observations. Actively monitor these channels to update your strategy as real ruling data becomes available.

• ›Treat every appearance as a first impression — Judge Martinez is newly on the bench and courtroom culture is still being established; professionalism and preparation will be noticed and remembered.
• ›Demonstrate genuine respect for opposing counsel and parties; a judge who spent 25 years representing indigent defendants is likely to be sensitive to power imbalances and dismissive or condescending behavior toward any party.
• ›Be precise and organized when presenting procedural arguments — her deep criminal procedure background means she will quickly identify sloppy or imprecise legal reasoning, particularly on constitutional and discovery issues.
• ›Confirm all scheduling, filing, and procedural requirements with her clerk in advance; do not assume standard department practices apply without verification during her early tenure.
• ›Avoid aggressive or combative courtroom tactics; given her advocacy background on behalf of vulnerable clients, a collaborative and respectful tone is likely to be better received than adversarial posturing.
• ›If appearing in a criminal matter, be prepared for substantive engagement on constitutional issues — do not treat due process or rights-based arguments as mere formalities, as she is likely to take them seriously.
