Biographical narrative
1,064 words · sourced from the Wikipedia REST extract
David R. Thompson was a United States circuit judge who served on the United States Court of Appeals for the Ninth Circuit from 1985 until his death in 2011. Born in San Diego, California, he spent nearly three decades on the federal appellate bench after a long career in private legal practice. Appointed by President Ronald Reagan, a Republican, Thompson was confirmed to a newly created seat on the Ninth Circuit in December 1985 and served in active status until assuming senior status at the end of 1998. He continued to hear cases and contribute to the work of the court for more than a dozen additional years in senior status, remaining active in the federal judiciary until shortly before his death.
Early life and legal career
David Renwick Thompson was born on December 26, 1930, in San Diego, California, where he would spend most of his professional life. He attended Point Loma High School in San Diego before pursuing higher education at the University of Southern California. Thompson completed his undergraduate studies at USC, earning a Bachelor of Science degree in business in 1952. He continued his education at the same institution, attending the University of Southern California Gould School of Law, where he obtained his Bachelor of Laws degree in 1955.
Upon completing his legal education, Thompson successfully passed the State Bar of California examination in 1955, qualifying him to practice law in the state. However, before beginning his legal career in earnest, Thompson fulfilled his military service obligation. He served in the United States Navy from 1955 to 1957, a period during which many young professionals of his generation contributed to the armed forces in the years following the Korean War.
After completing his naval service in 1957, Thompson returned to San Diego and entered private practice. He would remain in private legal practice in his hometown for nearly three decades, from 1957 until his appointment to the federal bench in 1985. During this extended period in private practice, Thompson built a career as a practicing attorney in Southern California, developing the expertise and professional reputation that would eventually lead to his nomination to the federal appellate judiciary. His twenty-eight years in private practice provided him with extensive experience in legal matters before he transitioned to the federal bench.
Federal appellate service
Thompson's path to the federal judiciary began in the fall of 1985, when President Ronald Reagan, a Republican, nominated him to serve on the United States Court of Appeals for the Ninth Circuit. The nomination, which came on October 7, 1985, was for a newly created judgeship on the circuit. This new seat had been authorized by federal legislation, specifically 98 Stat. 333, as part of an expansion of the federal judiciary to address growing caseloads in the federal appellate courts.
The United States Senate confirmed Thompson's nomination on December 16, 1985, and he received his commission the following day, on December 17, 1985. With this appointment, Thompson joined one of the largest and most geographically expansive federal appellate courts in the nation. The Ninth Circuit has jurisdiction over federal appeals from district courts in multiple western states and territories, and Thompson would serve on this court for the remainder of his life.
Thompson served in active status as a circuit judge for thirteen years. On December 31, 1998, he assumed senior status, a form of semi-retirement available to federal judges who meet certain age and service requirements. Senior status allows federal judges to continue hearing cases and contributing to the work of their courts while carrying a reduced caseload and creating a vacancy that allows for the appointment of a new active judge. Thompson's decision to take senior status at the end of 1998 followed a substantial period of service in active status, during which he participated in the adjudication of numerous appeals and contributed to the development of federal law within the Ninth Circuit.
Rather than retiring completely, Thompson remained active in senior status for more than twelve additional years. He continued to hear oral arguments and decide cases as a senior judge, maintaining his involvement with the Ninth Circuit's work well into the twenty-first century. His extended service in senior status demonstrated his continued commitment to the federal judiciary and his willingness to contribute to the administration of justice even after assuming a reduced workload.
Thompson's service came to an end in early 2011. He had traveled to San Francisco to hear oral arguments in several cases before the court. While in San Francisco for this judicial business, he suffered a sudden illness. Thompson died on February 19, 2011, at St. Mary's Medical Center in San Francisco. His death marked the conclusion of more than twenty-five years of service on the Ninth Circuit, during which he participated in the federal appellate process through both his active service and his extended tenure in senior status.
Jurisprudence and legacy
Thompson's quarter-century on the Ninth Circuit spanned a significant period in the development of federal law in the western United States. As a member of one of the nation's busiest federal appellate courts, he participated in the resolution of appeals covering the full range of federal jurisdiction, including matters of constitutional law, federal statutory interpretation, administrative law, and civil and criminal procedure. The Ninth Circuit's broad geographic jurisdiction meant that Thompson's work on the court affected legal developments across multiple states and territories.
His service bridged different eras of the federal judiciary, beginning during the Reagan administration and continuing through subsequent decades of legal and social change. Thompson's tenure in active status during the late 1980s and 1990s placed him on the court during a period of significant evolution in various areas of federal law, and his continued service in senior status allowed him to remain engaged with the court's work into the early twenty-first century.
The length of Thompson's service, spanning from 1985 until 2011, provided continuity on a court that handles a substantial volume of appeals and addresses diverse legal questions arising from its expansive jurisdiction. His willingness to continue serving in senior status for more than twelve years after assuming that status reflected a sustained dedication to the work of the federal appellate courts. Thompson's death while actively engaged in judicial duties—having traveled to San Francisco to hear oral arguments—underscored his commitment to judicial service that continued until the end of his life.
