Prior to his judicial career, Plager accumulated extensive experience as a naval officer, law professor, dean, and federal administrator, contributing scholarly works on administrative law and intellectual property.

Early life and legal career

S. Jay Plager was born in Long Branch, New Jersey, the son of A.L. Plager and Clara Plager. He attended public schools in his hometown before enrolling at the University of North Carolina, where he earned a Bachelor of Arts degree in 1952. Following his undergraduate studies, Plager entered the United States Navy, beginning a military career that would span more than two decades. He received his commission as an ensign in 1952 and served on active duty after World War II, ultimately attaining the rank of commander before retiring from the service in 1970.

While serving in the Navy, Plager pursued legal education. He obtained a Juris Doctor with high honors from the University of Florida College of Law in 1958 and subsequently earned a Master of Laws from Columbia Law School in 1961. His academic credentials laid the foundation for a parallel career in legal scholarship and teaching.

Plager’s first faculty appointment was at the University of Florida, where he served as a law professor from 1958 to 1963. He then joined the faculty of the University of Illinois College of Law, remaining there until 1977. During this period, he developed expertise in administrative and intellectual‑property law, topics that would later feature prominently in his judicial work. In 1977, Plager was appointed dean and professor at the Indiana University Maurer School of Law, a position he held through 1984. His deanship involved overseeing academic programs, faculty recruitment, and curricular reforms.

In addition to his permanent appointments, Plager held several visiting positions that broadened his scholarly perspective. He taught as a visiting professor at the University of Wisconsin Law School and served as a visiting scholar at Stanford Law School. Internationally, he was a visiting fellow at both Cambridge University and the Rockefeller Foundation Research Center, engagements that facilitated comparative legal research.

Plager’s experience extended beyond academia into federal administration. From 1986 to 1987, he acted as counselor to the undersecretary of the United States Department of Health and Human Services, providing legal advice on regulatory matters. He subsequently joined the Office of Management and Budget, where he served three years as associate director and later as administrator of the Office of Information and Regulatory Affairs (OIRA). In that capacity, Plager was responsible for reviewing federal regulations, coordinating inter‑agency policy development, and ensuring compliance with executive directives concerning rulemaking.

Throughout his career, Plager authored numerous articles and books on topics ranging from administrative law to patent policy. His scholarly output reflects a sustained engagement with the legal issues that intersect governmental regulation and private rights, an orientation that would inform his later judicial philosophy.

Federal appellate service

The Senate confirmed Plager’s appointment on November 8, 1989, and he received his commission three days later, on November 11. He occupied the seat designated as CAFC0802 on the Federal Circuit bench.
