This joint resolution proposes a constitutional amendment prohibiting total outlays for a fiscal year from exceeding total receipts for that fiscal year or 18% of the U.S. gross domestic product unless Congress authorizes the excess by a two-thirds vote of each chamber. The prohibition excludes outlays for repayment of debt principal and receipts derived from borrowing. The amendment requires a two-thirds vote of each chamber of Congress to levy a new tax, increase the rate of any tax, or increase the debt limit. The amendment provides any Member of Congress with standing and a cause of action to seek judicial enforcement of this amendment if authorized by a petition signed by one-third of the Members of either chamber of Congress. Courts are prohibited from ordering any increase in revenue to enforce this amendment.
