One Subject at a Time Act

HR 4324, the "One Subject at a Time Act," requires every federal bill or joint resolution to address only one specific topic, with that topic clearly stated in the bill's title. This applies to all legislation, including appropriations bills, which cannot include unrelated "general legislation" or changes to existing law outside their funding purpose. If a bill violates this rule - by having an unclear title or containing provisions not matching the title - the offending parts (or the entire bill) become invalid. Anyone harmed by a non-compliant bill, including citizens or lawmakers, can file a court challenge to block its enforcement. The law aims to ensure legislative clarity and prevent "rider" provisions in bills.
