Requires every bill or joint resolution to focus on a single subject that is clearly stated in the bill’s title, and bars appropriations bills from including unrelated general laws or changes to existing law (other than spending limits). It also creates rules that can void a law or parts of a law if the title and content do not match or if appropriations fall outside a subcommittee’s jurisdiction or are irrelevant to the bill.

Gives any aggrieved person or any Member of Congress the right to sue the United States to stop enforcement of a law that violates these rules, directs courts to review such challenges anew (de novo), and permits courts to void whole laws or specific provisions that fail to meet the title/content or jurisdictional requirements.
