The original act was to have expired in 1962, but was amended twice to allow more time to sell the tribal assets. As time wore on, Belvin realized that the bill severed the tribe members' access to government loans and other services, including the tribal tax exemption. By 1967, he had asked Oklahoma Congressman Ed Edmondson to try to repeal the termination act. Public sentiment was changing as well. The Choctaw people had seen what termination could do to tribes, since they witnessed the process with four other tribes in Oklahoma: the Wyandotte Nation, Peoria Tribe of Indians of Oklahoma, Ottawa Tribe of Oklahoma, and Modoc Tribe of Oklahoma. In 1969, ten years after passage of the Choctaw termination bill and one year before the Choctaws were to be terminated, word spread throughout the tribe that Belvin's law was a termination bill. Outrage over the bill generated a feeling of betrayal, and tribal activists formed resistance groups opposing termination. Groups such as the Choctaw Youth Movement in the late 1960s fought politically against the termination law. They helped create a new sense of tribal pride, especially among younger generations. Their protest delayed termination; Congress repealed the law on 24 August 1970.
