By 26 March 1957 a committee, under the chairmanship of Bill Osceola had been formed to draft a constitution and corporate charter. The Constitutional Committee members were: Billy Osceola and John Henry Gopher (Brighton), Bill Osceola and Jack Willie (Dania), Jimmie O. Osceola and Frank J. Billie (Big Cypress), and Larry Mike Osceola (Trail, but not of the Trail faction). Once the documents were prepared meetings were held on each reservation to discuss them with the tribespeople. The constitution and bylaws were accepted by tribal vote on 21 August 1957 by a vote of 241 for and 5 against.
