This joint resolution proposes a constitutional amendment that would require the federal government to balance its budget by ensuring that spending does not exceed revenues based on the average of the previous three years of income. The amendment would establish new budget procedures, including a biannual appropriations process requiring Congress to make appropriation bills available publicly at least 72 hours before a vote, and would create a budget stabilization fund that builds to 10 percent of annual revenue over ten years to cover emergencies and revenue shortfalls. It would grant the President line-item veto power over appropriations that would cause spending to exceed revenues, though Congress could override such vetoes with a three-fourths majority vote. The amendment also establishes a Taxation, Spending, and Budget Reform Commission that would meet every ten years while the national debt exceeds 60 percent of gross domestic product to recommend tax, spending, and budget reforms. The amendment would take effect two years after being ratified by three-fourths of the states, affecting all future federal budgeting and spending decisions.
