One Subject at a Time Act

S 59, the "One Subject at a Time Act," requires all bills and joint resolutions to address only one topic, clearly stated in the title. It prohibits bundling unrelated provisions, especially in appropriations bills, and voids any non-conforming sections or entire bills if they violate this rule. The law allows any person or member of Congress to sue the government to stop enforcement of non-compliant bills, with courts reviewing such cases de novo. This directly affects legislators drafting bills, congressional committees, and the judicial process for challenging legislation. It aims to prevent "rider" provisions and ensure bills focus on a single legislative purpose.
