The bill S. 476 proposes the establishment of a "Joint Committee on Federalism" within the South Carolina General Assembly, aimed at evaluating certain federal laws. The committee will consist of key legislative leaders from both the Senate and the House of Representatives, including the President Pro Tempore and the Speaker of the House, who will serve as co-chairmen. The committee is mandated to meet at least four times a year and will be staffed by the General Assembly. It will assess whether federal laws are authorized by the U.S. Constitution and whether they violate the principles of federalism, which include the distribution of power between state and national governments.

If the committee finds that a federal law is unauthorized or violates federalism principles, it may request meetings with Congress members and make recommendations to the General Assembly. Additionally, the committee is required to prepare an annual report detailing its findings and actions, which will be made publicly available on the General Assembly's website. The bill emphasizes the importance of evaluating federal laws in relation to the U.S. Constitution and the rights of states, aiming to protect state sovereignty and interests.
