Proposing a balanced budget amendment to the Constitution of the United States.

H.J.Res. 12 proposes a constitutional amendment requiring the federal government to balance its budget annually, meaning spending cannot exceed revenue except under specific circumstances. It would directly affect Congress and the President by mandating that annual budgets must not exceed revenue, with exceptions requiring a 3/5 vote in both chambers of Congress or a military conflict waiver approved by a joint resolution. Key provisions include prohibiting increases to the national debt without a 3/5 congressional vote, requiring the President to submit a balanced budget proposal each year, and defining "receipts" to exclude borrowing. The amendment would take effect five years after ratification by 38 states (three-fourths of states) and includes limited waivers for declared wars or imminent national security threats. This is a procedural constitutional change, not a spending bill, and would fundamentally alter federal budgeting processes.
