Section 23. (1) The Congress, by a vote of two-thirds of both Houses in joint session assembled, voting separately, shall have the sole power to declare the existence of a state of war. (2) In times of war or other national emergency, the Congress may, by law, authorize the President, for a limited period and subject to such restrictions as it may prescribe, to exercise powers necessary and proper to carry out a declared national policy. Unless sooner withdrawn by resolution of the Congress, such powers shall cease upon the next adjournment thereof. Section 24. All appropriation, revenue or tariff bills, bills authorizing increase of the public debt, bills of local application, and private bills, shall originate exclusively in the House of Representatives, but the Senate may propose or concur with amendments. Section 25. (1) The Congress may not increase the appropriations recommended by the President for the operation of the Government as specified in the budget. The form, content, and manner of preparation of the budget shall be prescribed by law. (2) No provision or enactment shall be embraced in the general appropriations bill unless it relates specifically to some particular appropriation therein. Any such provision or enactment shall be limited in its operation to the appropriation to which it relates. (3) The procedure in approving appropriations for the Congress shall strictly follow the procedure for approving appropriations for other departments and agencies. (4) A special appropriations bill shall specify the purpose for which it is intended, and shall be supported by funds actually available as certified by the National Treasurer, or to be raised by a corresponding revenue proposal therein. (5) No law shall be passed authorizing any transfer of appropriations; however, the President, the President of the Senate, the Speaker of the House of Representatives, the Chief Justice of the Supreme Court, and the heads of Constitutional Commissions may, by law, be authorized to augment any item in the general appropriations law for their respective offices from savings in other items of their respective appropriations. (6) Discretionary funds appropriated for particular officials shall be disbursed only for public purposes to be supported by appropriate vouchers and subject to such guidelines as may be prescribed by law. (7) If, by the end of any fiscal year, the Congress shall have failed to pass the general appropriations bill for the ensuing fiscal year, the general appropriations law for the preceding fiscal year shall be deemed re-enacted and shall remain in force and effect until the general appropriations bill is passed by the Congress. Section 26. (1) Every bill passed by the Congress shall embrace only one subject which shall be expressed in the title thereof.
