Partial Summary Judgments: When Grave Abuse of Discretion Opens the Door to Certiorari

The Supreme Court recently clarified an important point in remedial law: while a partial summary judgment is generally interlocutory and cannot be appealed separately, an aggrieved party may still assail it through a petition for certiorari under Rule 65 when its issuance was attended by grave abuse of discretion. The ruling in Bases Conversion and Development Authority v. Callangan, Jr. (G.R. No. 241168, August 22, 2022) also underscores that a tax declaration cannot be ordered issued when genuine issues of ownership remain unresolved.

The Case: A Dispute Over Land in Fort Bonifacio

The case involved two parcels of land within the Diplomatic and Consular Area (DCA) in Fort Bonifacio, Taguig. In 2009, then-President Gloria Macapagal-Arroyo declared the DCA alienable and disposable and placed it under the administration of the Bases Conversion and Development Authority (BCDA).

In July 2017, Pedro Callangan, Jr. and Elizabeth Barba-Azares filed a complaint for recovery of possession, cancellation and issuance of tax declarations, and damages against BCDA and the City Assessor of Taguig. They claimed ownership of the properties, having purchased them in 1976, and alleged that BCDA had taken possession by cordoning off the area and posting notices declaring the property belonged to the Republic.

BCDA countered that the respondents' claim of ownership was spurious, invoking the Regalian doctrine and arguing that the property remained part of the inalienable public domain. The City Assessor, for his part, admitted that issuing tax declarations is a ministerial duty but argued he was justified in exercising prudence given the contested nature of the property.

The Partial Summary Judgment

In December 2017, the respondents moved for a partial summary judgment on their first cause of action, arguing that no genuine issue existed on the City Assessor's duty to issue a tax declaration. The trial court granted the motion, ordering the City Assessor to issue tax declarations in favor of the respondents' predecessors-in-interest.

BCDA directly petitioned the Supreme Court, arguing that the trial court committed grave abuse of discretion because genuine issues of ownership were apparent. The respondents moved to dismiss, claiming the assailed order was interlocutory and that the petition was premature.

The Ruling: Remedies for Assailing a Partial Summary Judgment

The Supreme Court granted BCDA's petition, clarifying the proper remedies for assailing summary judgments.

A full summary judgment that disposes of the entire case is final in nature and may be appealed under Rule 41 or reviewed via a Rule 45 petition. A partial summary judgment, however, is interlocutory—it does not end the case but merely specifies facts deemed established for trial. As such, it cannot be separately appealed, nor can it be the subject of a writ of execution.

However, the Court clarified that the general rule against separately assailing a partial summary judgment is not absolute. Citing earlier jurisprudence, the Court held that certiorari under Rule 65 is available when the issuance of the partial summary judgment was attended by grave abuse of discretion—such as when the trial court manifestly disregarded basic rules and procedures, or when the judgment was rendered in derogation of the requirements of Rule 35 of the Rules of Court.

In this case, the Court found that the trial court gravely abused its discretion. The pleadings and supporting documents clearly showed genuine issues of ownership, including BCDA's challenge to the authenticity of the respondents' titles and its claim that the property was part of the public domain. The issue of ownership was intertwined with the respondents' entitlement to a tax declaration. A tax declaration is not proof of ownership; it is merely evidence of possession. Ordering its issuance while ownership remained hotly contested was a patent error.

Practical Takeaways

• A partial summary judgment is interlocutory and generally cannot be appealed separately; it is reviewed only with the final judgment on the entire case.
• Certiorari under Rule 65 is an available remedy when the issuance of a partial summary judgment was attended by grave abuse of discretion amounting to lack or excess of jurisdiction.
• A trial court commits grave abuse of discretion when it grants a partial summary judgment despite genuine issues of material fact apparent on the face of the pleadings.
• A tax declaration is not a proof of ownership. Courts should not order its issuance when the ownership of the property is genuinely disputed.
• A Rule 45 petition is only available to assail a full summary judgment, not an interlocutory partial summary judgment.
