Veto Power of the Local Chief Executive. -

(a) The local chief executive may veto any ordinance of the sanggunian panlalawigan, sangguniang panlungsod, or sanggunian bayan on the ground that it is ultra vires or prejudicial to the public welfare, stating his reasons therefor in writing.

(b) The local chief executive, except the punong barangay, shall have the power to veto any particular item or items of an appropriations ordinance, an ordinance or resolution adopting a local development plan and public investment program, or an ordinance directing the payment of money or creating liability. In such a case, the veto shall not affect the item or items which are not objected to. The vetoed item or items shall not take effect unless the sanggunian overrides the veto in the manner herein provided; otherwise, the item or items in the appropriations ordinance of the previous year corresponding to those vetoed, if any, shall be deemed reenacted.

(c) The local chief executive may veto an ordinance or resolution only once. The sanggunian may override the veto of the local chief executive concerned by two-thirds (2/3) vote of all its members, thereby making the ordinance effective even without the approval of the local chief executive concerned.
