After World War II, Holman returned to Oregon, where he was appointed to the
Clackamas County Circuit Court by Governor
Douglas McKay in 1950. The
United States Supreme Court left this decision intact when they denied
certiorari. In 1964, Holman was elected to the
Oregon Supreme Court, the state's highest court, filling the position of
George Rossman whose term had expired. During the summer of 1967, Holman was a judge in residence at
New York University School of Law, a fellowship for appellate judges that was awarded by the Institute of Judicial Administration. At the request of his fellow justices, Holman created the plan to establish the
Oregon Court of Appeals, which was approved by the State Bar Association and Oregon Legislature in 1969. Before the end of his final term, he submitted his resignation to Governor
Victor Atiyeh on October 16, 1979, citing his advancing age. His resignation became effective January 20, 1980, after 30 years on the Oregon bench. ==Later life and family==
