The main purpose of this legislation is to modify the rules regarding membership in the Catawba Indian Tribe of South Carolina. Specifically, it aims to change the requirements for individuals seeking to become members of the Tribe. The key provision of this legislation removes a specific requirement that individuals must be direct descendants of someone on a final membership roll and must maintain political relations with the Tribe to be eligible for membership. By eliminating this stipulation, the law opens the door for more individuals to potentially join the Tribe.
