The Edmunds–Tucker Act of 1887 was an Act of Congress that focused on restricting some practices of The Church of Jesus Christ of Latter-day Saints (LDS Church). It was passed in response to the dispute between the United States Congress and the LDS Church regarding polygamy. The act is found in US Code Title 48 & 1461, full text as 24 Stat. 635, with this annotation to be interpreted as Volume 24, page 635 of United States Statutes at Large. The act is named after its congressional sponsors, Senator George F. Edmunds of Vermont and Congressman John Randolph Tucker of Virginia.
The act was repealed in 1978.
The act disincorporated both the LDS Church and the Perpetual Emigration Fund on the grounds that they fostered polygamy. The act prohibited the practice of polygamy and punished it with a fine of from $500 to $800 and imprisonment of up to five years. It dissolved the corporation of the church and directed the confiscation by the federal government of all church properties valued over a limit of $50,000. The act was enforced by the U.S. Marshal and a host of deputies.
