Section 13December 22, 1997, Sec./Art. 13

(a) Every bill shall embrace only one (1) subject which shall be expressed in the title thereof.

(b) No bill 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 the members three (3) days before its passage, except when the governor certifies to the necessity of its immediate enactment to meet a public calamity or emergency affecting the region, or the component provinces, cities, municipalities or barangays. 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.

(c) Every bill passed by the Legislative Assembly shall, before it becomes a law, be presented to the regional governor. If he approves the same, he shall sign it; otherwise, he shall veto it and return the same with his objections to the Legislative Assembly, which shall enter the objections in its Journal and proceed to reconsider it. If, after such reconsideration, two-thirds (2/3) of all the members of the assembly shall agree to pass the bill, it shall become a law. The regional governor shall communicate his veto of any bill to the assembly within thirty (30) days after the date of receipt thereof; otherwise, it shall become a law as if he had signed it.

(d) The regional governor shall have the power to veto any particular item or items in an appropriation or revenue, but the veto shall not affect the item or items to which he does not object.
