The 27th Utah Territorial Legislature met in 1886. The regular election for the Territorial Council and the House of Representatives was held August 3, 1885.
The legislative session convened on January 11, 1886, at the City Hall in Salt Lake City, and ended on March 12, 1886.
The House seat for Summit County faced a similar dispute to the House seat for Tooele in the Legislative Assembly of 1876. The Liberal Party ticket secured a rare victory over the dominant People's Party of the Mormon establishment, leading to the election of David C. McLaughlin to the House. Losing candidate Ward E. Pack, who had previously represented Summit in the legislatures of 1876 and 1880, sought to contest the result, alleging illegal votes in the Park City precincts from which McLaughlin hailed. However, with the election overseen by the federal government's Utah Commission under the Edmunds Act, claims of fraud were rejected and the Liberal victory upheld.
