Facts:
The Municipality of Binan Laguna issued Municipal Resolution No. 284 which approved Mun. Ord. No. 06, an ordinance regulating the use of urban control zones for agricultural use, gradually phasing out large piggery, fowl, and other livestock farms located within the Municipality of Binan, providing penalties, and for other purposes.
Holiday Hills and Domino Farms filed a Petition for Certiorari, Declaratory Relief, and Prohibition with application for Preliminary Injunction and/or prayer for Temporary Restraining Order8 before the RTC, assailing the validity of Municipal Ordinance No. 06, specifically sections 2,3,and 6 for being vague, whimsical, arbitrary, and capricious and unconstitutional.
The RTC dismissed the petition stating that it was issued in the exercise of police power and since the facilities were located near residential subdivisions, it therefore constitute a nuisance per se.
Holiday Hills and Domino appealed before the CA which reversed the RTC decision. It found that the ordinance violated Holiday Hills' and Domino Farms' right to substantial due process 19 because their hog farms are not a nuisance per se but a nuisance per accidens, which cannot be abated via an ordinance.
Issue:
Whether or not the CA correctly reversed the RTC Decision and declared the invalidity of Municipal Ordinance No. 06.
