Philippine Ports Authority v. City of Davao: Jurisdiction and Forum Shopping in Real Property Tax Cases

The Supreme Court's 2018 ruling in Philippine Ports Authority v. City of Davao clarifies two important points for taxpayers and local governments alike: first, once a real property tax case reaches the Court of Tax Appeals (CTA), that court alone has the power to issue injunctive relief; and second, filing a separate case in another court while an appeal is pending before the CTA constitutes forum shopping. The decision serves as a practical reminder that procedural choices can be as decisive as the merits of a tax dispute.

The Facts of the Case

The Philippine Ports Authority (PPA), a government instrumentality created under Presidential Decree No. 857, owned properties at Sasa Port in Davao City. In June 2004, the City Assessor assessed real property taxes on these properties. PPA appealed the assessment to the Local Board of Assessment Appeals, but the appeal was dismissed for being filed out of time. The Central Board of Assessment Appeals (CBAA) affirmed this dismissal.

PPA then filed an appeal with the CTA. While that appeal was pending, the City of Davao proceeded to auction and sell three of PPA's properties to satisfy the alleged tax liabilities. PPA did not file a motion for injunctive relief with the CTA. Instead, it filed a petition for certiorari and prohibition with the Court of Appeals (CA), arguing that the city's taxation and sale of its properties were unlawful and that it needed urgent relief.

The Issue

The Supreme Court addressed two questions: (1) Did the CA have jurisdiction to issue the injunctive relief PPA sought? and (2) Was PPA's petition before the CA properly dismissed for forum shopping?

The Ruling

The Court denied PPA's petition, affirming the CA's dismissal.

On jurisdiction. Under Section 7(a)(5) of Republic Act No. 1125, as amended by Republic Act No. 9282, the CTA has exclusive appellate jurisdiction over decisions of the CBAA in cases involving the assessment and taxation of real property. Because PPA's appeal before the CTA concerned the very same CBAA decision, the CTA had exclusive jurisdiction over the matter.

The Court rejected PPA's argument that urgency justified filing with the CA. Citing City of Manila v. Grecia-Cuerdo, the Court explained that the CTA has the power to issue writs of certiorari and injunctive relief in aid of its appellate jurisdiction. A grant of appellate jurisdiction necessarily includes the power to issue all auxiliary writs necessary to preserve the subject of the appeal and to give effect to the final determination. Once the CTA acquired jurisdiction over PPA's appeal, the CA was precluded from taking cognizance of the case.

On forum shopping. The Court also affirmed the finding that PPA committed forum shopping. Forum shopping occurs when a party institutes more than one action based on the same cause, with identity of parties, rights asserted, and reliefs prayed for, such that judgment in one case would amount to res judicata in the other. PPA argued that its CA petition asserted a different right—peaceful possession of its ports—and sought different relief—temporary injunction—than its CTA appeal. However, because PPA failed to attach copies of its pleadings before the CTA and the CA, the Court could not verify these claims. The Court therefore upheld the CA's finding of forum shopping.

Why This Matters

This case is a practical guide for taxpayers challenging real property tax assessments. The remedy depends on the stage of enforcement. When a case is already on appeal with the CTA, that court is the proper venue for all related relief, including injunctions against levy or auction. Filing a separate action elsewhere not only wastes time and resources but also exposes the taxpayer to dismissal for forum shopping.

Practical Takeaways

• Know the exclusive jurisdiction of the CTA. Appeals from CBAA decisions on real property tax assessments must be brought to the CTA, not the CA.
• Seek injunctive relief from the right court. If a local government threatens to levy or auction property while a tax case is pending, apply for a preliminary injunction with the CTA—not the CA.
• Avoid forum shopping. Filing parallel cases in different courts based on the same facts and issues invites dismissal. Ensure that each action asserts distinct rights and seeks distinct reliefs.
• Preserve the record. When appealing, attach all relevant pleadings. Failure to do so may prevent the reviewing court from verifying claims of distinct causes of action.
• Act promptly. The CTA has the power to issue all auxiliary writs necessary to protect its jurisdiction. Use that remedy early rather than pursuing a separate action.
