Thomas Emmet Pyne, 84, a retired administrative law judge at the Interstate Commerce Commission who was active in church and music groups, died at Georgetown University Hospital Nov. 2 of neck injuries he received in a fall at his home in Washington.

Judge Pyne was born in Chicago and reared in Washington. He graduated from Gonzaga College High School and earned his law degree at Georgetown University. He served in the Army in World War I.

In 1920, he was appointed an attorney in the ICC. He later became a principal hearing examiner and specialized in time zones as they relate to scheduling and other matters. Hearing examiners later were redesignated administrative law judges and Judge Pyne served in this capacity until his retirement in 1964.

He was a parishioner of St. Anne's Catholic Church, where he was a member of the choir and the organist for the Holy Name Society. He also sang at St. Matthew's Cathedral and other churches. In 1974, he received the Church Music Award from the Washington Archdiocese.

Judge Pyne was a member of the choral group at the ICC and the Aloysius quartet and players, two organizations he joined while a student at Gonzaga. He was a member of the Washington Civic Opera Society and the North Cleveland Park Citizens Association.

His first wife, the former Frances Wunder, died in 1954.

Jr. of Ocala, Fla., and John J. of Washington; three sisters, Agnes Cooper and Margaret Horan, both of Washington, and Dorothy Krebs of Bethesda, and 25 grandchildren.
