The Local Government Unit entitled
To Collect Real Property Taxes
The Former Seventh Division of the Court of Appeals held that the resolution of the complaint lodged before the Pasig RTC did not necessitate the assessment of the parties’ evidence on the metes and bounds of their respective territories. It cited our ruling in Odsigue v. Court of Appeals[27] wherein we said that a certificate of title is conclusive evidence of both its ownership and location.[28] The Court of Appeals even referred to specific provisions of the 1991 Local Government Code and Act. No. 496 to support its ruling that Pasig had the right to collect the realty taxes on the subject properties as the titles of the subject properties show on their faces that they are situated in Pasig.[29]
Under Presidential Decree No. 464 or the “Real Property Tax Code,” the authority to collect real property taxes is vested in the locality where the property is situated:
Sec. 5. Appraisal of Real Property. — All real property, whether taxable or exempt, shall be appraised at the current and fair market value prevailing in the locality where the property is situated.

Sec. 57. Collection of tax to be the responsibility of treasurers. — The collection of the real property tax and all penalties accruing thereto, and the enforcement of the remedies provided for in this Code or any applicable laws, shall be the responsibility of the treasurer of the province, city or municipality where the property is situated. (Emphases ours.)
This requisite was reiterated in Republic Act No. 7160, also known as the 1991 the Local Government Code, to wit:
Section 201. Appraisal of Real Property. – All real property, whether taxable or exempt, shall be appraised at the current and fair market value prevailing in the locality where the property is situated. The Department of Finance shall promulgate the necessary rules and regulations for the classification, appraisal, and assessment of real property pursuant to the provisions of this Code.
Section 233. Rates of Levy. – A province or city or a municipality within the Metropolitan Manila Area shall fix a uniform rate of basic real property tax applicable to their respective localities as follows: x x x. (Emphases ours.)
The only import of these provisions is that, while a local government unit is authorized under several laws to collect real estate tax on properties falling under its territorial jurisdiction, it is imperative to first show that these properties are unquestionably within its geographical boundaries.
Accentuating on the importance of delineating territorial boundaries, this Court, in Mariano, Jr. v. Commission on Elections[30] said:
The importance of drawing with precise strokes the territorial boundaries of a local unit of government cannot be overemphasized. The boundaries must be clear for they define the limits of the territorial jurisdiction of a local government unit. It can legitimately exercise powers of government only within the limits of its territorial jurisdiction. Beyond these limits, its acts are ultra vires. Needless to state, any uncertainty in the boundaries of local government units will sow costly conflicts in the exercise of governmental powers which ultimately will prejudice the people's welfare. This is the evil sought to be avoided by the Local Government Code in requiring that the land area of a local government unit must be spelled out in metes and bounds, with technical descriptions.[31] (Emphasis ours.)
The significance of accurately defining a local government unit’s boundaries was stressed in City of Pasig v. Commission on Elections,[32] which involved the consolidated petitions filed by the parties herein, Pasig and Cainta, against two decisions of the Commission on Elections (COMELEC) with respect to the plebiscites scheduled by Pasig for the ratification of its creation of two new Barangays. Ruling on the contradictory reliefs sought by Pasig and Cainta, this Court affirmed the COMELEC decision to hold in abeyance the plebiscite to ratify the creation of Barangay Karangalan; but set aside the COMELEC’s other decision, and nullified the plebiscite that ratified the creation of Barangay Napico in Pasig, until the boundary dispute before the Antipolo RTC had been resolved. The aforementioned case held as follows:
1. The Petition of the City of Pasig in G.R. No. 125646 is DISMISSED for lack of merit; while
2. The Petition of the Municipality of Cainta in G.R. No. 128663 is GRANTED. The COMELEC Order in UND No. 97-002, dated March 21, 1997, is SET ASIDE and the plebiscite held on March 15, 1997 to ratify the creation of Barangay Napico in the City of Pasig is declared null and void. Plebiscite on the same is ordered held in abeyance until after the courts settle with finality the boundary dispute between the City of Pasig and the Municipality of Cainta, in Civil Case No. 94-3006.[33]
Clearly therefore, the local government unit entitled to collect real property taxes from Sta. Lucia must undoubtedly show that the subject properties are situated within its territorial jurisdiction; otherwise, it would be acting beyond the powers vested to it by law.
