ARTICLE VI

Legislative Department

SECTION 1. The legislative power shall be vested in the Congress of the Philippines which shall consist of a Senate and a House of Representatives, except to the extent reserved to the people by the provision on initiative and referendum.

SECTION 15. The Congress shall convene once every year on the fourth Monday of July for its regular session, unless a different date is fixed by law, and shall continue to be in session for such number of days as it may determine until thirty days before the opening of its next regular session, exclusive of Saturdays, Sundays, and legal holidays. The President may call a special session at any time.

SECTION 21. The Senate or the House of Representatives or any of its respective committees may conduct inquiries in aid of legislation in accordance with its duly published rules of procedure. The rights of persons appearing in or affected by such inquiries shall be respected.

SECTION 22. The heads of departments may upon their own initiative, with the consent of the President, or upon the request of either House, as the rules of each House shall provide, appear before and be heard by such House on any matter pertaining to their departments. Written questions shall be submitted to the President of the Senate or the Speaker of the House of Representatives at least three days before their scheduled appearance. Interpellations shall not be limited to written questions, but may cover matters related thereto. When the security of the State or the public interest so requires and the President so states in writing, the appearance shall be conducted in executive session.

SECTION 24. All appropriation, revenue or tariff bills, bills authorizing increase of 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 26. (1) Every bill passed by the Congress shall embrace only one subject which shall be expressed in the title thereof.
(2) No bill passed by either House shall become a law unless it has passed three readings on separate days, and printed copies thereof in its final form have been distributed to its members three days before its passage, except when the President certifies to the necessity of its immediate enactment to meet a public calamity or emergency. Upon the last reading of a bill, no amendment thereto shall be allowed, and the vote thereon shall be taken immediately thereafter, and the yeas and nays entered in the Journal.

SECTION 27. (1) Every bill passed by the Congress shall, before it becomes a law, be presented to the President. If he approves the same, he shall sign it; otherwise, he shall veto it and return the same with his objections to the House where it originated, which shall enter the objections at large in its Journal and proceed to reconsider it. If, after such reconsideration, two-thirds of all the Members of such House shall agree to pass the bill, it shall be sent, together with the objections, to the other House by which it shall likewise be reconsidered, and if approved by two-thirds of all the Members of that House, it shall become a law. In all such cases, the votes of each House shall be determined by yeas or nays, and the names of the Members voting for or against shall be entered in its Journal. The President shall communicate his veto of any bill to the House where it originated within thirty days after the day of receipt thereof; otherwise, it shall become a law as if he had signed it.
(2) The President shall have the power to veto any particular item or items in an appropriation, revenue, or tariff bill, but the veto shall not affect the item or items to which he does not object.
