G.R. No. 120082 - MACTAN CEBU INTERNATIONAL AIRPORT AUTHORITY, VS. HON. FERDINAND J. MARCOS, IN HIS CAPACITY AS THE PRESIDING JUDGE OF THE REGIONAL TRIAL COURT, BRANCH 20, CEBU CITY, THE CITY OF CEBU, REPRESENTED BY ITS MAYOR, HON. TOMAS R. OSMEÑA, AND EUSTAQUIO B. CESA.

Ruling

Accordingly, tax statutes must be construed strictly against the government and liberally in favor of the taxpayer. [16] But since taxes are what we pay for civilized society, [17] or are the lifeblood of the nation, the law frowns against exemptions from taxation and statutes granting tax exemptions are thus construed strictissimi juris against the taxpayer and liberally in favor of the taxing authority. [18] A claim of exemption from tax payments must be clearly shown and based on language in the law too plain to be mistaken. [19] Elsewise stated, taxation is the rule, exemption therefrom is the exception. [20] However, if the grantee of the exemption is a political subdivision or instrumentality, the rigid rule of construction does not apply because the practical effect of the exemption is merely to reduce the amount of money that has to be handled by the government in the course of its operations. [21] The power to tax is primarily vested in the Congress; however, in our jurisdiction, it may be exercised by local legislative bodies, no longer merely by virtue of a valid delegation as before, but pursuant to direct authority conferred by Section 5, Article X of the Constitution. [22] Under the latter, the exercise of the power may be subject to such guidelines and limitations as the Congress may provide which, however, must be consistent with the basic policy of local autonomy. There can be no question that under Section 14 of R.A. No. 6958 the petitioner is exempt from the payment of realty taxes imposed by the National Government or any of its political subdivisions, agencies, and instrumentalities. Nevertheless, since taxation is the rule and exemption therefrom the exception, the exemption may thus be withdrawn at the pleasure of the taxing authority. The only exception to this rule is where the exemption was granted to private parties based on material consideration of a mutual nature, which then becomes contractual and is thus covered by the non-impairment clause of the Constitution. [23] The LGC, enacted pursuant to Section 3, Article X of the Constitution, provides for the exercise by local government units of their power to tax, the scope thereof or its limitations, and the exemptions from taxation. Section 133 of the LGC prescribes the common limitations on the taxing powers of local government units as follows: SEC. 133. Common Limitations on the Taxing Power of Local Government Units. -- Unless otherwise provided herein, the exercise of the taxing powers of provinces, cities, municipalities, and barangays shall not extend to the levy of the following: (a) Income tax, except when levied on banks and other financial institutions; (b) Documentary stamp tax; (c) Taxes on estates, inheritance, gifts, legacies and other acquisitions mortis causa, except as otherwise provided herein; (d) Customs duties, registration fees of vessel and wharfage on wharves, tonnage dues, and all other kinds of customs fees, charges and dues except wharfage
