One Subject at a Time Act

S 287, the "One Subject at a Time Act," requires each legislative bill or joint resolution to address only one main topic, with that topic clearly stated in the bill's title. It voids any provisions in a bill that cover topics not described in the title, and specifically prohibits appropriations bills from containing unrelated general legislation. This applies to all federal bills, with violations allowing affected individuals or members of Congress to sue to block enforcement of non-compliant bills. The law directly affects lawmakers drafting bills and courts reviewing legislative proposals for procedural compliance.
