Roger I. McDonough (September 29, 1892 – November 25, 1966) was an American judge. He was judge of the Third Judicial District Court from 1928 to 1938, then served on the Utah Supreme Court from 1938 to 1966. It was the longest tenure of any judge in Utah's history at the time of his death. He was the Chief Justice of the Utah Supreme Court from 1947 to 1948 and from 1954 to 1959, and was called upon by President Harry S. Truman to serve on emergency fact-finding boards to help settle labor disputes in the steel and railroad industries.
Roger I. McDonough was born September 29, 1892, in Park City, Utah. He was the son of Irish immigrants Bartley and Minnie Power McDonough. Upon graduation from Park City High School, he was hired to teach history and geography in the Park City Schools, and eventually was made principal of the Jefferson School.
A veteran of World War I, McDonough joined the army October 3, 1917, and was commissioned a second lieutenant in the field artillery in September 1918.
He attended Notre Dame University and the University of Utah Law School. He was the state deputy for the Knights of Columbus from 1921-1922. He served as Summit County Attorney prior to being elected Third District Court judge. He was married to Mildred Ann Devine by Catholic Archbishop John Joseph Mitty in San Francisco in May, 1932.
McDonough was a judge in the Third District Court from 1928 to 1938. For six of those years, his fellow justices selected him to serve as presiding judge of the district court. One of the interesting cases before Judge McDonough's court was the 1935 conviction of Secretary of State Milton Welling on the charge of submitting a false salary request. Before sentencing, the Utah Supreme Court intervened; ultimately, Judge McDonough ordered a new trial, and the Secretary of State was acquitted. In 1938, he called a grand jury to investigate vice protection payoffs in Salt Lake County.
He was elected to the Utah Supreme Court in 1938.
Like previous justices of the Utah Supreme Court, McDonough was called upon to rule in polygamy prosecutions. In 1950, he was on a three-member panel that dismissed a polygamy prosecution on the grounds that the statute was too vague.
On December 31, 1945, President Harry S. Truman appointed Judge McDonough, with University of Wisconsin Law Professor Nathan Feinsinger and Missouri Supreme Court Chief Justice James Marsh Douglas, to a presidential fact-finding board, to investigate an ongoing labor dispute in the steel industry in which 700,000 steelworkers threatened to strike. The strike was not averted, but the board's report contributed to the eventual settlement.
In 1950, President Truman again appointed McDonough to an Emergency Board to help settle a labor dispute, this time between the railroads and their workers, to try to avoid a railroad strike.
He died in Salt Lake City, Utah on November 25, 1966.
