After World War II, Holman returned to Oregon, where he was appointed to the Clackamas County Circuit Court by Governor Douglas McKay in 1950. He served as a circuit court judge for 15 years, until 1965. While on the bench in that court, he served on the Committee on the Administration of Justice created by the Oregon Legislature, and was chairman of the subcommittee on Juvenile Law. Through his efforts on this committee, the legislature passed a law which allowed for abusive parents to lose their parental rights, thereby enabling abused children to become adopted. Holman's 1960 decision in Dickman v. School District No. 62C, a case that allowed the use of public funds for purchasing textbooks for parochial schools, spurred an appeals process that ultimately led to the United States Supreme Court. His decision was overturned by the Oregon Supreme Court, which argued the "child benefit" theory could not be used to justify public expenditures for private causes. 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. Holman won re-election to additional six-year terms in 1970 and 1976. His opinion in Portland Section of Council of Jewish Women vs. Sisters of Charity is often cited as an example of impracticability in contract law. 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
In 1937, he married Louise Mariam Oesch, who died in 1989. They did not have any children. Holman was a Life Trustee at Lewis & Clark College, which honored him with the Aubrey Watzik award, and the distinguished graduate award from Lewis & Clark Law School. For many years, he served as the Chairman of the Law School budget committee. Until the end of his life, Holman served as a senior judge for the state of Oregon, in which the Chief Justice of the Oregon Supreme Court is allowed to appoint retired justices on a temporary needed basis. In 2005, at the age of 91, Holman and other family members created the Holman Family Scholarship for graduates of Molalla High School. Clackamas County Courthouse opened the Ralph M. Holman Law Center in 2007, its first expansion in 71 years, which houses offices for drug and DUII court, court reporters, jury assembly rooms, and the Alden Miller Law Library. Holman was an avid fly fisherman, which led him to travel extensively throughout South America, Asia, and the Pacific Northwest. He and his wife were passionate collectors of art and antiques, and cultivated roses. Holman died at his home in Salem, Oregon on September 3, 2013, at the age of 99.
