Judge Daniel A. Ottolia

Judge Daniel A. Ottolia serves on the Riverside County Superior Court, appointed by Governor Gavin Newsom in January 2021. His most prominent pre-appointment judicial work — conducted while he was already presiding in Riverside County — involved California's End of Life Option Act. In 2016, he rejected opponents' attempts to block the law, and then in May 2018, he overturned it entirely, ruling it unconstitutional on the grounds that the legislature had improperly passed it during a special legislative session. Critically, his 2018 ruling was grounded in legislative procedure rather than the substantive policy merits of doctor-assisted suicide, demonstrating a judicial approach that prioritizes procedural and constitutional correctness over outcome-driven reasoning. This pattern — ruling against a law not because of what it does, but because of how it was enacted — signals a judge who takes procedural integrity seriously and is willing to issue consequential rulings when procedural defects are clearly established. His willingness to reach a significant constitutional conclusion on procedural grounds, even in a high-profile and politically sensitive case, reflects a disciplined, process-oriented judicial temperament. Attorneys should understand that Judge Ottolia's rulings are anchored in legal mechanics and proper procedure, not in the perceived equities or political valence of a case.

Given the documented evidence that Judge Ottolia issued a major ruling on procedural and constitutional grounds in the End of Life Option Act case, attorneys should ensure that their motions and briefs are procedurally airtight. Any argument that relies on procedural defects — improper notice, statutory authority, jurisdictional prerequisites — should be developed fully and placed prominently, as the record shows this judge acts on such grounds when they are well-supported. Attorneys should not assume that the substantive strength of their position will carry the day if procedural requirements have not been met. Conversely, if opposing counsel has committed a procedural error, that defect should be clearly identified and briefed, as the record demonstrates Judge Ottolia is willing to rule on those grounds. Arguments should be structured to address threshold procedural and constitutional questions before moving to the merits, mirroring the analytical framework his documented rulings reflect. Because no attorney observations or ruling analyses beyond the End of Life Option Act matter are available, attorneys should conduct independent research into Judge Ottolia's post-2021 Superior Court rulings in Riverside County to supplement this profile before appearing before him.
