Judge Daniel J. Lowenthal Jr.

Judge Daniel J. Lowenthal Jr. sits in Department S22 at the Santa Monica Courthouse, Los Angeles County Superior Court. He was elected to the bench in 2006 and is assigned to that department. Public records also reflect a 2021 appointment notation associated with Governor Newsom, indicating a subsequent appointment event in his judicial career. He is the son of state Senator Alan Lowenthal and Long Beach Councilwoman Bonnie Lowenthal, placing him within a family with significant California public service history. Beyond these biographical and appointment facts, no ruling analyses, attorney observations, or ingested content are available in the current data set. As a result, no patterns regarding his judicial philosophy, ruling tendencies, motion practice preferences, or courtroom demeanor can be stated with evidentiary support at this time. Attorneys preparing to appear before Judge Lowenthal should treat the guidance below as a framework for due diligence rather than a profile built on observed behavioral data.

Because no ruling analyses or attorney observations are available, attorneys cannot rely on a data-driven profile of Judge Lowenthal's preferences at this time. The most productive preparation strategy is to research recent published and unpublished rulings from Department S22 directly through the Los Angeles Superior Court's online docket system and through Trellis or similar legal research platforms, focusing on any orders issued in the months preceding your appearance. Given that Judge Lowenthal has been on the bench since 2006, he is an experienced jurist. Attorneys should approach his courtroom with the standard professionalism expected of a long-tenured Los Angeles Superior Court judge: thorough briefing, precise citation to authority, and strict compliance with local rules and department-specific standing orders. Checking the Santa Monica Courthouse's posted standing orders for Department S22 before any appearance is essential, as individual departments frequently maintain specific procedural requirements not captured in general court rules.
