One Bill, One Subject Transparency Act

HR 91, the "One Bill, One Subject Transparency Act," requires every legislative bill or joint resolution to address only one subject, clearly stated in its title. This applies to all bills, including appropriations bills, which cannot include unrelated "rider" provisions. If a bill violates this rule - by having an unclear title or containing unrelated provisions - the entire bill, or the specific non-compliant parts, becomes void. The law allows any person, including members of Congress, to challenge non-compliant bills in court after the bill is signed into law. This is a procedural rule focused on legislative clarity, not on changing substantive policy.
