Judge Jonathan Robert Hayes

Judge Jonathan Robert Hayes serves on the Sacramento Superior Court following his appointment by Governor Gavin Newsom on March 25, 2021. His entire pre-bench legal career was spent at a single firm — Dreyer Babich Buccola Wood Campora LLP — where he progressed from Law Clerk (2000–2004) through Associate (2004–2013) to Partner (2013–2021). This firm is a well-known Sacramento plaintiffs' personal injury and wrongful death litigation firm, meaning Judge Hayes spent approximately 21 years in civil litigation with a plaintiff-side orientation before taking the bench. Because no ruling analyses, attorney observations, or ingested content are available for this judge, no patterns in his judicial decision-making can be reported at this time. What is known is that he received his J.D. from the University of the Pacific, McGeorge School of Law in 2004 and his undergraduate degree from Pennsylvania State University in 1999. His depth of experience in civil trial practice — spanning two decades at one firm — is the primary factual foundation available for understanding his background. Attorneys appearing before Judge Hayes should recognize that the absence of ruling data means preparation must rely on direct courtroom observation, consultation with local Sacramento practitioners who have appeared before him since 2021, and standard professional conduct. No shortcuts based on assumed patterns are warranted given the current data limitations.

Given Judge Hayes's documented background as a career civil litigator at a plaintiffs' personal injury firm, attorneys on both sides of civil matters should be prepared for a judge with substantial hands-on familiarity with civil procedure, discovery disputes, damages arguments, and trial practice. His two decades of active litigation experience at a single firm suggest he will recognize procedural gamesmanship and is unlikely to be impressed by arguments that lack substantive grounding. Because no ruling data exists in this dataset, attorneys cannot rely on documented tendencies for motion practice, tentative ruling procedures, or preferred briefing styles. The most effective preparation strategy is to consult with Sacramento-area practitioners who have appeared before Judge Hayes since his 2021 appointment, review any publicly available tentative rulings through the Sacramento Superior Court's online system, and arrive fully prepared on both the law and the facts without assuming any particular predisposition. Attorneys should also be aware that judges appointed as part of large group appointments — as Hayes was, among 18 appointees on March 25, 2021 — often come from active practice rather than prior judicial or government roles, reinforcing the importance of treating him as a practitioner-turned-judge who values practical, well-organized advocacy.

  Check Sacramento Superior Court Local Rules

  In the absence of judge-specific behavioral data, strict compliance with Sacramento Superior Court local rules and standing orders is essential. Confirm current department-specific procedures directly with the court clerk.

• ›Follow all Sacramento Superior Court local rules and any department-specific standing orders, which should be confirmed with the clerk prior to any appearance.
• ›Do not assume familiarity with plaintiff or defense-side framing based solely on Hayes's pre-bench background — present arguments on their merits with full evidentiary support.
• ›Consult the Sacramento Superior Court tentative ruling system before each hearing and be prepared to address the court's stated reasoning directly.
