Elder Dallin H. Oaks served his community as a justice of the Utah Supreme Court before he served the Church as a general authority. He spent four years in that former role, starting in 1980, before resigning his position in 1984 to accept a calling to the apostleship.
Oaks also served five years as chairman of the board of directors of PBS and eight years as a chairman of the board of directors of the Polynesian Cultural Center.
