Water Production Assessments: When Regular Courts, Not the NWRB, Have Jurisdiction

When a government-owned water district seeks to collect production assessments from a business that operates its own deep wells, which court or agency has the authority to hear the dispute? This question was at the heart of Dasmariñas Water District v. Monterey Foods Corporation (G.R. No. 175550, September 17, 2008), where the Supreme Court settled a jurisdictional conflict between the regular courts and the National Water Resources Board (NWRB).

The Facts of the Case

Dasmariñas Water District, a government-owned corporation created under Presidential Decree No. 198 (the Provincial Water Utilities Act of 1973), filed a complaint against Monterey Foods Corporation for payment of production assessments. Monterey operated two deep wells in Dasmariñas, Cavite, with water permits issued by the NWRB, using the water solely for its livestock and agriculture business.

The water district invoked Section 39 of PD 198, which allows a water district to levy a ground water production assessment when the production of ground water by other entities within the district for commercial or industrial uses is injuring or reducing the district's financial condition. The water district sought monthly assessments totaling P55,112.46, plus damages and attorney's fees.

Monterey moved to dismiss the case, arguing that the NWRB—not the Regional Trial Court (RTC)—had jurisdiction under the Water Code of the Philippines (PD 1067). The RTC denied the motion, but the Court of Appeals reversed, holding that the NWRB had original jurisdiction over the dispute. The water district appealed to the Supreme Court.

The Issue

The sole issue was whether the RTC or the NWRB had jurisdiction over the collection of water production assessments under Section 39 of PD 198.

The Ruling

The Supreme Court ruled in favor of the water district, holding that the regular courts—specifically the RTC—had jurisdiction over the case.

The Court applied the fundamental principle that jurisdiction is determined by the allegations in the complaint. Examining the water district's complaint, the Court found that it involved the determination and enforcement of the water district's right under PD 198 to impose production assessments—not a dispute over the appropriation, utilization, or use of water, nor the adjudication of the parties' respective water rights.

The water district was not challenging the validity of Monterey's water permits. Both parties had established rights to use water: the water district by virtue of its charter under PD 198, and Monterey through its NWRB-issued permits. What was at issue was whether the water district could levy an assessment to compensate for the financial injury caused by Monterey's ground water production.

The Court distinguished this case from those where the NWRB's jurisdiction properly applies. Citing Atis v. CA and Amistoso v. Ong, the Court explained that the NWRB's original jurisdiction under Article 88 of PD 1067 covers disputes relating to the appropriation, utilization, exploitation, development, control, conservation, and protection of waters. However, where the parties already have established water rights and the dispute concerns the enjoyment of those rights or a claim for damages arising from interference, the regular courts have jurisdiction.

Why the Regular Courts Had Jurisdiction

The Court reasoned that the claim under Section 39 of PD 198 related to prejudice or damage to the water district's finances, which gave it the right to levy a production assessment. The provision also entitled the water district to injunction and damages in case of failure to pay. This was a judicial question—one involving the determination of what the law is and what the legal rights of the parties are—properly addressed to the courts.

The Court also held that the doctrine of primary jurisdiction did not apply because the technical expertise of the NWRB was not required to resolve the issue. The action fell within the exclusive jurisdiction of the RTC because it was incapable of pecuniary estimation under Section 19(1) of Batas Pambansa Blg. 129, as amended by RA 7691. Although the complaint included a claim for a sum of money, that claim was purely incidental to the principal relief sought—the determination of the water district's entitlement to impose the assessment.

Other Points Decided

The Court also addressed two procedural matters. First, the Court of Appeals erred in ruling on whether the water district had authority to impose production assessments, because this issue was not raised before the trial court. Points of law and arguments not brought to the attention of the trial court cannot be raised for the first time on appeal.

Second, Monterey's challenge to the constitutionality of Section 39 of PD 198 as an undue delegation of legislative power was a collateral attack on a presumably valid law. The Court reiterated that laws are presumed valid, and their constitutionality cannot be attacked collaterally—it must be raised in a direct proceeding and pleaded at the earliest opportunity.

Practical Takeaways

• Jurisdiction is determined by the complaint's allegations. If the dispute centers on enforcing a statutory right to collect assessments—not on water rights themselves—the regular courts, not the NWRB, have jurisdiction.
• The NWRB's jurisdiction is limited. Under Article 88 of PD 1067, the NWRB handles disputes over water appropriation, utilization, and related matters. Where parties already hold established water rights, disputes over the enjoyment of those rights belong to the courts.
• Collateral attacks on laws are not allowed. A party cannot challenge the constitutionality of a statute in a motion to dismiss or as a side issue; it must be raised directly and at the earliest opportunity.
• Issues must be raised in the trial court first. Arguments not presented before the trial court cannot be raised for the first time on appeal.
