1987 Constitution of the Philippines
Section 27.
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 date of receipt thereof, otherwise, it shall become a law as if he had signed it.
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.
