A law passed by Congress is a formal legal statute that has been approved by both houses of Congress—the House of Representatives and the Senate—and then signed into law by the President. These laws are crucial for establishing and modifying regulations that govern society, impacting various aspects of public policy, individual rights, and the balance of power within the government. The process of passing a law involves several stages, including proposal, debate, amendments, and voting, demonstrating the checks and balances inherent in the legislative process.
