Implied Consent and Jurisdiction: When Unpleaded Issues Become Part of a Case

The Supreme Court's decision in D.M. Wenceslao & Associates, Inc. v. Freyssinet Philippines, Inc. (G.R. No. 166857, September 11, 2009) clarifies a fundamental rule in Philippine civil procedure: when parties try an issue not stated in the pleadings, with the express or implied consent of the adverse party, the court may validly rule on it. This principle, rooted in Section 5, Rule 10 of the Rules of Court, prevents technicalities from defeating substantial justice.

The Facts of the Case

In January 1989, D.M. Wenceslao & Associates, Inc. (DMWAI) undertook the construction of the National Historical Institute Building. Freyssinet Philippines, Inc. (FPI) supplied pre-stressed piles for the project under a contract worth P2,600,000, with a 30% down payment and the balance payable through progress payments.

When FPI filed a complaint for collection in 1993, it sought payment for the NHI project. Later, FPI amended its complaint to implead DMWAI as a party defendant. During trial, evidence emerged concerning a separate account — the International Bank for Reconstruction and Development (IBRD) account — which was not specifically alleged in the complaint.

The Issue

The central question was whether the trial court acquired jurisdiction over the IBRD account even though it was not expressly pleaded in FPI's complaint. DMWAI argued that the court's application of Section 5, Rule 10 was misplaced, insisting that the IBRD account was "merely mentioned" during trial to prove an off-setting agreement.

The Ruling

The Supreme Court denied DMWAI's petition and affirmed the Court of Appeals' decision. The Court held that a court may validly render judgment on issues not alleged in the pleadings when evidence on those issues is presented with the express or implied consent of the adverse party.

The Court cited Bank of America v. American Realty Corporation (378 Phil. 1279 [1999]), which stated: "When evidence is presented by one party, with the express or implied consent of the adverse party, as to issues not alleged in the pleadings, judgment may be rendered validly as regards those issues, which shall be considered as if they have been raised in the pleadings. There is implied consent to the evidence thus presented when the adverse party fails to object thereto."

Key Considerations in the Case

Several factors supported the Court's finding of implied consent. The pre-trial order defined the issues to include whether there was an off-setting agreement between the parties and whether a balance remained collectible. DMWAI did not object to FPI's Exhibit "J," which showed an outstanding balance of P618,796 for the IBRD account — in fact, DMWAI even adopted the same document as its own exhibit. Wenceslao, Jr. also admitted that the company still had an outstanding balance with FPI, though not for the NHI project.

The Court emphasized that DMWAI was not prejudiced. Both parties had full opportunity to present evidence and refute each other's claims. As the Court noted, "so long as the basic requirements of fair play had been met, as where litigants were given full opportunity to support their respective contentions and to object to or refute each other's evidence, the court may validly treat the pleadings as if they had been amended to conform to the evidence."

Interest and Damages

The Court also addressed the applicable interest rate. Since the 18% per annum rate stipulated in the contract pertained only to the NHI project (which had been fully paid), and no evidence showed an agreed rate for the IBRD account, the Court applied the legal interest of 6% per annum under Article 2209 of the Civil Code, computed from the filing of the complaint. Once the judgment became final and executory, the rate increased to 12% per annum until full payment.

The Court likewise deleted the awards of attorney's fees and litigation expenses, finding no proof that DMWAI acted in gross and evident bad faith.

Practical Takeaways

• Failure to object can be costly. When an opposing party presents evidence on matters outside the pleadings, silence may be treated as implied consent under Section 5, Rule 10 of the Rules of Court.
• Pre-trial orders matter. Issues defined during pre-trial, even if not in the original complaint, may be considered properly tried if evidence is presented without objection.
• Adopting the adverse party's evidence carries risk. Using an opponent's exhibit as one's own can strengthen a finding of implied consent to the issues it raises.
• Interest rates are not automatic. Absent a stipulation, the legal interest of 6% per annum applies under Article 2209 of the Civil Code, with 12% per annum after judgment becomes final and executory.
• Fair play is the touchstone. Courts will uphold rulings on unpleaded issues where parties had full opportunity to present and refute evidence.
