After eleven years as Choctaw chief, Belvin persuaded Representative Carl Albert of Oklahoma to introduce federal legislation to begin terminating the Choctaw tribe. On 23 April 1959, the BIA confirmed that H.R. 2722 had been submitted to Congress at the request of the tribe. It would provide for the government to sell all remaining tribal assets, but would not affect any individual Choctaw earnings. It also provided for the tribe to retain half of all mineral rights, to be managed by a tribal corporation.
