When parties proceed to trial without objecting to defects in a complaint, those defects are deemed waived. If a plaintiff introduces evidence to support a cause of action not initially pleaded, and the defendant willingly presents evidence to counter it, the issue is considered fully joined. This means the court can proceed as if the issue was properly raised from the beginning, ensuring fairness and efficiency in resolving disputes.

The Case of the Contested Land: When Silence Implies Consent

This case revolves around Lolita Ayson’s challenge to the jurisdiction of the Municipal Trial Court (MTC) in an ejectment suit filed against her by Marina Enriquez Vda. de Carpio. Ayson argued that the complaint filed by Carpio was defective and failed to properly establish a cause of action for ejectment, essentially claiming that the MTC lacked the authority to hear the case, suggesting it should have been brought before the Regional Trial Court (RTC) instead. This dispute underscores a critical principle: Can a party challenge a court’s jurisdiction after actively participating in the trial without raising such objections initially? The resolution of this question has significant implications for how procedural defects in pleadings are treated in Philippine courts.

The controversy began with Ayson’s properties, which were mortgaged to the Philippine National Bank (PNB) and subsequently foreclosed. After Ayson failed to redeem the properties, PNB sold one of them to Carpio. Carpio then filed an ejectment case against Ayson when she refused to vacate the property. Ayson contended that Carpio’s complaint did not adequately state the grounds for unlawful detainer, suggesting that Carpio was asserting ownership rights, which would fall under the jurisdiction of the RTC rather than the MTC. The appellate court found that Ayson’s continued possession was merely tolerated by Carpio and that the ejectment suit was the proper remedy.

The Supreme Court, in its analysis, underscored the significance of Section 5 of Rule 10 of the Rules of Court, which deals with amendments to conform to evidence. This provision allows issues not initially raised in the pleadings to be treated as if they were, provided they are tried with the express or implied consent of the parties. Here’s the key provision:

“SEC. 5. – Amendment to conform to or authorize presentation of evidence.– When issues not raised by the pleadings are tried with the express or implied consent of the parties, they shall be treated in all respects as if they had been raised in the pleadings. Such amendment of the pleadings as may be necessary to cause them to conform to the evidence and to raise these issues may be made upon motion of any party at any time, even after judgment; but failure to amend does not affect the result of the trial of these issues. If evidence is objected to at the trial on the ground that it is not within the issues made by the pleadings, the court may allow the pleadings to be amended and shall do so with liberality if the presentation of the merits of the action and the ends of substantial justice will be subserved thereby. The court may grant a continuance to enable the amendment to be made.”

The Court noted that Ayson actively participated in the trial without objecting to the alleged defects in Carpio’s complaint. This participation included presenting her own evidence and arguments, such as challenging Carpio’s possession and alleging fraud in the property’s acquisition. By doing so, Ayson impliedly consented to the trial of issues beyond the original pleadings. Therefore, the defects in the complaint were effectively cured. Moreover, the evidence presented during the trial revealed that Carpio had a better right to possess the property due to Ayson’s failure to redeem it after foreclosure.

The Supreme Court also addressed Ayson’s argument regarding the lack of clear evidence of her receipt of the demand letter to vacate the premises. The Court emphasized that this issue was raised for the first time on appeal, preventing them from considering it. The principle that issues not raised in the lower courts cannot be raised on appeal is a fundamental aspect of Philippine procedural law, ensuring fairness and preventing parties from ambushing the opposing side with new arguments at a late stage.

Consequently, the Court affirmed the CA’s decision, holding that the MTC had jurisdiction over the ejectment case. The ruling reinforces the principle that active participation in a trial without objection constitutes a waiver of defects in the pleadings, highlighting the importance of timely raising procedural issues to prevent their waiver. This decision ensures that the proceedings remained valid despite the initial imperfections in the complaint. By allowing the case to proceed based on the evidence presented and the issues tried by consent, the Court upheld the interests of justice and fairness.
