Legislation must adhere to the principles of bicameralism and presentment to align with constitutional requirements. Bicameralism ensures that both chambers of Congress, the House of Representatives and the Senate, must pass legislation before it can become law. Presentment requires that the President must then be given the opportunity to sign or veto the proposed legislation.
For example: A bill promoting energy efficiency must be approved by both the House and the Senate, and subsequently presented to the President, who might sign it into law or veto it, kickstarting a potential override process in Congress.
