Function of Section 187
Section 187 of the Local Government Code supplies the special procedure for questioning the constitutionality or legality of a local tax ordinance or revenue measure. It recognizes that local governments may enact tax measures under delegated taxing power, but it subjects that power to procedural safeguards, statutory limitations, and judicially enforceable constitutional limits.
The provision has two connected functions. First, it requires that local tax ordinances and revenue measures pass through the approval and effectivity rules of the Code, including the conduct of public hearings before enactment. Second, it creates a remedy: any question on constitutionality or legality may be brought on appeal to the Secretary of Justice within thirty days from the effectivity of the measure.
The remedy is directed at the ordinance or revenue measure itself, not merely at the computation of a particular taxpayer's liability. The issue under Section 187 is whether the local law validly exists, validly took effect, and validly imposes the tax, fee, or charge according to the Constitution, the Local Government Code, and other controlling statutes.
Local Taxing Power and Validity
Local governments do not possess inherent taxing power. Their authority to levy taxes, fees, and charges comes from the Constitution and from statutory delegation, especially the Local Government Code. The constitutional policy of local autonomy gives local governments fiscal space, but that autonomy operates within guidelines and limitations prescribed by Congress.
A local tax ordinance is valid only when the local legislative body acts within delegated authority. The ordinance must be enacted by the proper sanggunian, must concern a taxable subject or activity that the local government may reach, must observe the required procedure for enactment and effectivity, and must not violate constitutional or statutory limitations.
The presumption of validity applies to local ordinances, including tax ordinances. The challenger must identify a constitutional, statutory, or procedural defect sufficient to overcome that presumption. At the same time, a local government cannot rely on local autonomy to sustain a tax that the law has withheld, prohibited, or conditioned on requirements that were not observed.
Measures Covered
Section 187 covers tax ordinances and revenue measures. A tax ordinance is a local legislative enactment that imposes a tax, fixes or changes a tax rate, identifies the tax base, regulates collection of the tax, or otherwise creates a local tax burden. A revenue measure is broader and may include ordinances imposing fees, charges, rentals, or other exactions intended to raise local revenue.
The provision reaches both new ordinances and amendments to existing revenue codes when the amendment affects the existence, amount, incidence, or enforceability of the local exaction. A measure cannot avoid Section 187 merely by being labeled regulatory if its operation imposes a revenue-raising burden on persons, property, businesses, or activities within the local jurisdiction.
The provision does not govern every disagreement involving local money claims. If the taxpayer accepts the validity of the ordinance but disputes the assessment, classification, rate application, deficiency computation, surcharge, interest, or factual basis of collection, the controversy normally falls under the remedies for assessment, protest, or refund rather than a Section 187 validity appeal.
Procedural Requirements for Validity
A local tax ordinance must comply with the approval and effectivity procedure prescribed by the Local Government Code. The required procedure includes deliberation and enactment by the sanggunian, approval by the local chief executive or passage under the rules on veto and reconsideration, and publication or posting sufficient to give legal notice before enforcement.
Public hearing is mandatory. It must occur before enactment, must relate to the proposed tax ordinance or revenue measure, and must give affected sectors a meaningful opportunity to be heard. A post-enactment consultation cannot cure the absence of the required pre-enactment hearing because the statutory safeguard is designed to inform the legislative decision before the burden is imposed.
Publication or posting is also part of legal effectivity. A tax ordinance that has not been published or posted in the manner required by the Code cannot be enforced as a binding revenue measure against persons who are entitled to notice of the local law. The thirty-day period for appeal under Section 187 is tied to the measure's effectivity, and legal effectivity presupposes compliance with the applicable notice requirements.
Noncompliance with mandatory procedural requirements is a legality issue. Thus, the absence of a required public hearing, defective publication, lack of sanggunian authority, or failure to follow the statutory approval process may be raised in a Section 187 appeal because each defect concerns the legal validity of the local measure itself.
Substantive Requirements for Validity
Even when properly enacted, a local tax ordinance must remain within the substantive limits of delegated taxing power. The tax must serve a public purpose, operate uniformly within the territorial jurisdiction of the local government, and avoid unjust, excessive, oppressive, confiscatory, or discriminatory effects.
The ordinance must not impose a tax that the Local Government Code or another statute reserves to the national government, prohibits to local governments, or assigns to a different local level. A province, city, municipality, or barangay may tax only within the field granted to it, and a lower local government cannot enlarge its taxing authority by ordinance.
The ordinance must also respect territorial limits. A local government may tax persons, properties, privileges, businesses, or activities that have sufficient connection to its territorial jurisdiction, but it cannot project its taxing power beyond its boundaries merely because a taxpayer has dealings with residents or consumers in the locality.
The tax base and rate must be ascertainable from the ordinance. A measure that leaves essential tax elements to uncontrolled administrative discretion risks invalidity because the legislative body, not the collecting officer, must determine the nature and extent of the tax burden.
Revenue ordinances must not defeat national statutes that expressly grant exemptions, immunities, or limitations that continue to bind local governments. Exemptions are not implied lightly, but when a valid statute clearly withdraws a subject from local taxation, a local ordinance imposing the tax is ultra vires.
Grounds Commonly Raised Under Section 187
- Lack of authority: the local government taxed a subject, person, business, privilege, or transaction outside its delegated taxing power.
- Violation of statutory limitations: the ordinance imposed a levy that the Local Government Code or another law prohibits, reserves, or restricts.
- Procedural defect: the ordinance was enacted without the required public hearing, approval process, publication, posting, or other mandatory step.
- Constitutional infirmity: the tax violates due process, equal protection, uniformity, non-impairment, public purpose, or other constitutional restraints.
- Excessive or oppressive burden: the levy is so unreasonable in amount or operation that it ceases to be a legitimate revenue measure.
- Territorial overreach: the ordinance taxes activities, property, or privileges beyond the territorial jurisdiction of the local government.
- Uncertain tax elements: the measure fails to identify with reasonable clarity the taxpayer, tax base, rate, period, or taxable activity.
Administrative Appeal to the Secretary of Justice
The Section 187 appeal must be filed within thirty days from the effectivity of the ordinance or revenue measure. The period is short because local fiscal measures are presumed needed for public services and because taxpayers and local governments require prompt certainty on the validity of revenue laws.
The appeal is addressed to the Secretary of Justice because the controversy concerns legality and constitutionality, not local policy wisdom. The Secretary reviews whether the local government acted within law; the review does not authorize substitution of national policy preferences for local legislative choices that remain legally permissible.
The Secretary of Justice must render a decision within sixty days from receipt of the appeal. The statutory period prevents administrative review from indefinitely delaying judicial recourse and local fiscal administration. If the Secretary acts, the aggrieved party may seek court review within thirty days from receipt of the decision. If the Secretary does not act within sixty days, the aggrieved party may file the appropriate court proceeding within thirty days from the lapse of that period.
The Section 187 appeal is part of the statutory remedy and is generally treated as the proper first step for a taxpayer who attacks the validity of the ordinance itself. A direct court action filed while the statutory administrative remedy remains available may be vulnerable to dismissal for prematurity or failure to follow the special procedure provided by law.
Non-Suspensive Effect of Appeal
An appeal to the Secretary of Justice does not suspend the effectivity of the ordinance. The local tax, fee, or charge continues to accrue and remains payable while the administrative appeal is pending, unless a competent court issues an injunctive or restraining order under the applicable rules.
This rule protects local government revenues from automatic paralysis by the mere filing of an appeal. It also means that a taxpayer challenging validity may need to consider payment under protest or other protective remedies when collection is pursued during the pendency of the validity challenge.
The non-suspensive effect does not validate an invalid ordinance. It only governs interim enforceability. If the measure is later declared void, the legal consequences of invalidity may include cessation of enforcement and recovery or credit of amounts collected, subject to the proper refund procedure and prescriptive periods.
Court Proceedings After Administrative Review
Section 187 allows the aggrieved party to file appropriate proceedings with a court of competent jurisdiction after receiving the Secretary's decision or after the lapse of the sixty-day period without action. The court, not the Secretary of Justice, has final authority to resolve constitutional questions and to issue binding judicial relief.
The proper judicial remedy depends on the relief sought and the posture of the controversy. A taxpayer may seek declaratory, injunctive, annulment, refund-related, or other appropriate relief when the pleadings and jurisdictional rules support it. The essential point is that the judicial action must be timely connected to the administrative review route required by Section 187.
The court may sustain the ordinance, invalidate it in whole, invalidate only the separable invalid provisions, or determine the legal consequences of the defect. Separability depends on whether the valid portions can stand independently and whether the local legislative body would have enacted them without the invalid part.
Validity Challenge Distinguished from Assessment Remedies
| Controversy | Primary Issue | Usual Remedy |
|---|---|---|
| Validity of ordinance | Whether the local tax ordinance or revenue measure is constitutional, legal, procedurally valid, and within delegated authority | Section 187 appeal to the Secretary of Justice, followed by timely court proceedings if necessary |
| Assessment under an ordinance | Whether the local treasurer correctly applied a valid ordinance to a taxpayer's facts, classification, gross receipts, situs, period, surcharge, or interest | Administrative protest against the assessment under the local tax remedies provided by the Code |
| Recovery of payment | Whether an amount already paid was illegally or erroneously collected | Written refund or credit claim with the local treasurer and, if unresolved or denied, timely judicial action under the refund rules |
The distinction matters because the wrong remedy may forfeit relief. A taxpayer who challenges the ordinance itself must observe the Section 187 periods. A taxpayer who merely disputes an assessment cannot convert that dispute into a Section 187 case by using general language about illegality when the real issue is factual application or computation.
The remedies may overlap when an assessment is based on an allegedly invalid ordinance. In that situation, the taxpayer should preserve the validity challenge through Section 187 while also protecting against collection or prescription under the assessment and refund provisions when payment or enforcement is involved.
Effect of Invalidity
An invalid local tax ordinance is void to the extent of the defect. If the local government lacked authority to impose the tax, the ordinance cannot create a lawful liability. If the defect lies only in a particular rate, classification, penalty, exemption clause, or administrative mechanism, the remaining provisions may survive if they are complete and enforceable on their own.
Collections made under an invalid ordinance are not automatically returned without compliance with the applicable refund procedure. The taxpayer must ordinarily make the required written claim within the statutory period and pursue judicial relief when the claim is denied, not acted upon, or otherwise requires court adjudication.
A declaration of invalidity also guides future local action. The sanggunian may enact a new ordinance that corrects the defect, but the new measure must independently comply with public hearing, approval, publication, effectivity, and substantive validity requirements. A curative ordinance cannot retroactively impose a tax burden for a period when no valid tax ordinance was in force unless a valid law clearly authorizes that effect.
Operational Rules for Analysis
- Identify the local measure and determine whether it is a tax ordinance or revenue measure within Section 187.
- Determine the date of legal effectivity, because the thirty-day appeal period runs from effectivity, not merely from approval or discovery.
- Check whether the mandatory public hearing, approval, publication, and posting requirements were observed.
- Determine whether the local government had delegated authority over the taxpayer, tax base, taxable activity, and territorial situs.
- Test the levy against constitutional limits, statutory limitations, and the Code's principles of local taxation.
- Separate a validity attack from an assessment, collection, or refund dispute, because each has its own remedy and period.
- Apply the non-suspensive effect of the Section 187 appeal unless judicial relief restrains enforcement.
- After the Secretary of Justice acts or fails to act within sixty days, observe the thirty-day period for appropriate court proceedings.
