Jurisdictional Estoppel When Participation Waives Objections in Property Disputes

The Supreme Court's decision in Bernardo v. Heirs of Villegas (G.R. No. 183357, March 15, 2010) clarifies an important principle in Philippine civil procedure: a party who actively participates in litigation cannot later question the court's jurisdiction after receiving an unfavorable judgment. The case illustrates how the doctrine of estoppel operates in property disputes involving accion publiciana.

The Facts of the Case

The respondents, heirs of Eusebio Villegas, filed an accion publiciana case against Honorio Bernardo and others for possession of a parcel of land covered by Transfer Certificate of Title No. 46891. The respondents claimed that Bernardo surreptitiously entered the property in 1996, initially pretending to graze cattle, before constructing a house and fencing the area.

The case had a procedural history. The respondents first filed an ejectment case before the Municipal Trial Court (MTC), which dismissed it for lack of jurisdiction since it was filed beyond the one-year prescriptive period for forcible entry. The respondents then filed the accion publiciana case before the Regional Trial Court (RTC).

The Issue on Jurisdiction

Bernardo argued that the RTC lacked jurisdiction because the complaint failed to state the assessed value of the disputed property. Under Republic Act No. 7691, which amended Batas Pambansa Blg. 129, RTCs have exclusive original jurisdiction over real actions where the assessed value of the property exceeds P20,000.00 (or P50,000.00 in Metro Manila). Without the assessed value alleged in the complaint, it could not be determined which court had jurisdiction.

The Supreme Court acknowledged that, as a general rule, jurisdiction may be questioned at any stage of the proceedings. Lack of jurisdiction affects the very authority of the court to render judgment, and a court may dismiss a case motu proprio on this ground.

The Doctrine of Estoppel

However, the Court applied the doctrine of estoppel, citing the landmark case of Tijam v. Sibonghanoy (131 Phil. 556 [1968]). The principle: a party who voluntarily submits to a court's jurisdiction and participates in all stages of litigation cannot belatedly challenge that jurisdiction when the decision is adverse.

The Court found that Bernardo's general allegation in his Answer that the "court has no jurisdiction over the subject matter" was insufficient. He failed to specifically raise the omission of the assessed value in the complaint. He actively participated in the trial—presenting evidence, filing pleadings, and submitting his case for decision—without ever raising the jurisdictional defect. It was only on appeal, after receiving an adverse judgment, that he raised the issue.

The Court's Ruling

The Supreme Court denied Bernardo's petition. The Court noted that the case had been pending for nearly ten years, was handled by two judges, and its records had to be reconstituted after a fire. Allowing Bernardo to question jurisdiction at that late stage would waste the time, effort, and expenses of all parties.

Significantly, the Court found that the RTC actually had jurisdiction. A technical report attached to the records contained a tax declaration showing the property's assessed value at P110,220.00—well above the P20,000.00 threshold. The tax declaration enjoys the presumption of regularity as it was issued by the proper government agency.

Practical Takeaways

• Raise jurisdictional defects early and specifically. A general allegation of lack of jurisdiction in an Answer is not enough. Identify the specific defect, such as the failure to allege the assessed value of the property.
• Active participation waives objections. Filing pleadings, presenting evidence, and submitting the case for decision can bar a party from later questioning jurisdiction, especially when the objection is raised only after an adverse ruling.
• Jurisdiction is determined by the assessed value. For real actions like accion publiciana, the complaint must allege the assessed value of the property to establish which court has jurisdiction.
• Tax declarations are persuasive evidence. A tax declaration indicating assessed value enjoys the presumption of regularity and can establish that the RTC had jurisdiction all along.
• Estoppel promotes judicial efficiency. Courts will not countenance the "undesirable practice" of accepting a judgment only when favorable and attacking it for lack of jurisdiction when adverse.
