Judge Theresa R. McGonigle

Judge Theresa R. McGonigle serves at the Stanley Mosk Courthouse as part of the Los Angeles County Superior Court, having been appointed by Governor Edmund G. Brown, Jr. on November 29, 2018. Her entire pre-bench career was spent within the Los Angeles County Superior Court system itself, beginning as a Law Clerk in 1989 and advancing through Research Attorney, Supervising Research Attorney, and Managing Research Attorney roles before her elevation to the bench. This career trajectory — spanning nearly three decades inside the court's research and legal analysis infrastructure — means Judge McGonigle brings an exceptionally deep institutional knowledge of how the Los Angeles Superior Court operates, how legal arguments are constructed and evaluated at the research level, and what standards of legal writing and analysis the court expects. Her academic background includes an undergraduate degree from Santa Clara University (1984) and a J.D. from Notre Dame Law School (1987). Her role as Managing Research Attorney from 2014 through 2018 placed her at the apex of the court's internal legal analysis function, where she oversaw the preparation of judicial research on complex legal questions. News coverage connects her to high-profile criminal matters, including cases involving mentally ill offenders and murder prosecutions, suggesting her docket includes serious criminal matters. Because no ruling analyses, attorney observations, or ingested content are available, behavioral patterns and courtroom tendencies cannot be drawn from empirical data at this time. The profile data provided establishes her background and career history with confidence, but assessments of her judicial temperament, ruling tendencies, and courtroom preferences await further data collection.

Judge McGonigle's entire career before taking the bench was devoted to legal research and analysis within the superior court system. Attorneys appearing before her should prioritize the quality and precision of their legal arguments. Her background as a Managing Research Attorney means she has personally evaluated the quality of legal briefs and research memoranda at a high level — sloppy citations, unsupported legal propositions, or weak case analysis will be immediately apparent to her. Briefs should be meticulously researched, with accurate citations and clear articulation of the controlling legal standards. Given her news coverage in connection with criminal matters involving mentally ill offenders and murder prosecutions, attorneys in serious criminal cases should be prepared for a judge who is familiar with the procedural and substantive complexity of high-stakes criminal litigation. If appearing in a criminal matter, thorough preparation on evidentiary standards, competency issues, and applicable penal code provisions is warranted. Because no direct attorney observations or ruling data are available, attorneys should not rely on assumptions about her courtroom preferences beyond what her career background directly supports. Consulting with practitioners who have appeared before her recently is the most reliable way to supplement the profile data currently available.
