Holding California State Bar license #90484 since 1979, Michael R Marrinan Law Offices in downtown San Diego pursues Section 1983 federal civil rights claims from a fifteenth-floor suite on West Broadway. The practice targets law-enforcement misconduct including excessive force, wrongful death, false arrest, and jail abuse—a caseload aligned with the civil-liberties mission of ACLU San Diego & Imperial Counties in Bankers Hill. A University of San Diego School of Law degree underpins a litigation strategy built on 42 U.S.C. § 1983, the federal statute allowing individuals to sue government officials for constitutional violations. Case preparation frequently requires forensic psychological documentation of custodial trauma and PTSD, coordinating with clinicians like Psychiatry And Counseling San Diego who evaluate post-incident mental-health damages for trial testimony. The highest-tier matters involve multi-plaintiff Monell liability actions challenging systemic municipal policies, coupled with Fourteenth Amendment custodial death investigations requiring forensic biomechanical reconstruction.
