Waiver of Defenses: How Untimely Pleadings Shape Construction Disputes

In a significant ruling for construction disputes, the Supreme Court clarified that a defendant who fails to raise a defense in its answer cannot later use it to defeat a contractor's claim. The case of Edron Construction Corporation v. Provincial Government of Surigao del Sur (G.R. No. 220211, June 5, 2017) demonstrates how procedural rules on waiver can determine the outcome of a case, regardless of the merits of the defense.

The Facts of the Case

Edron Construction Corporation and Edmer Y. Lim entered into three construction agreements with the Provincial Government of Surigao del Sur. The projects — a Learning Resource Center, a bus/jeepney terminal, and a public market — were completed and accepted by the province, as evidenced by Certificates of Final Acceptance. Despite this, the province failed to pay the contractor the aggregate amount of P8,870,729.67.

The contractor filed a complaint for specific performance and damages. In its Answer with Counterclaim filed on January 6, 2009, the province admitted the existence of the contracts but raised defenses relating to alleged underruns, defective works, and prescription.

More than a year later, the province filed a Motion to Dismiss on the ground of failure to state a cause of action. It argued that under Paragraph 4.3, Article IV of the construction agreements, final payment could only be made after the contractor submitted a sworn statement attesting that all obligations for labor and materials had been fully paid. Since no such sworn statement was submitted, the province claimed the contractor had no cause of action.

The Procedural Issue

The Supreme Court focused on a critical procedural question: Could the province raise the non-submission of the sworn statement as a defense when it was not pleaded in the answer?

The answer was no.

Under Section 1, Rule 9 of the Rules of Court, defenses and objections not pleaded in a motion to dismiss or in the answer are deemed waived. The rule provides only four exceptions: lack of jurisdiction over the subject matter, litis pendentia (another action pending between the same parties), res judicata (prior judgment), and prescription.

The defense of non-submission of the sworn statement did not fall under any of these exceptions. It was raised only in the Motion to Dismiss, which was filed more than a year after the answer — clearly out of time. Under Section 1, Rule 16 of the Rules of Court, a motion to dismiss must be filed within the time for filing the answer, but before the answer is actually filed.

The Court's Ruling

The Supreme Court reversed the Court of Appeals and reinstated the trial court's decision in favor of the contractor. The Court held that the Court of Appeals erred in dismissing the complaint on a ground that was belatedly and improperly raised by the province.

The Court emphasized that the province had issued Certificates of Final Acceptance stating that the projects were satisfactorily completed and free from major defects. These certificates, combined with the province's failure to properly raise the sworn statement defense, meant the contractor was entitled to payment.

The contractor was awarded P4,326,174.50, representing the reduced valuation from the Presidential Flagship Committee that the contractor had accepted, plus legal interest and attorney's fees.

Practical Takeaways

• Pleadings matter. A defendant must raise all available defenses in its answer or in a timely motion to dismiss. Defenses not raised are deemed waived, except for the four exceptions under Rule 9: lack of jurisdiction, litis pendentia, res judicata, and prescription.

• Timing is critical. A motion to dismiss must be filed within the period for filing an answer, not after. A late motion cannot resurrect defenses that should have been pleaded earlier.

• Certificates of acceptance are powerful evidence. When an owner issues a Certificate of Final Acceptance, it becomes difficult to later deny liability for payment, especially if the owner fails to substantiate claims of defects or deviations.

• Contract conditions must be raised promptly. If an owner intends to rely on a contractual condition precedent (like a sworn statement requirement), that defense must be pleaded in the answer. Raising it years later in a motion to dismiss will not be entertained.

• Interest rates follow prevailing rules. The Court applied the Nacar v. Gallery Frames ruling, imposing 12% interest per annum from demand until June 30, 2013, and 6% per annum thereafter until full payment.
