Defective Summons Voids Trustee Appointment: Key Lessons from Diversified Plastic Film v. PI-One

The Supreme Court's ruling in Diversified Plastic Film System, Inc. v. Philippine Investment One (SPV-AMC), Inc. underscores a fundamental principle: a court cannot act on a party over whom it has not acquired jurisdiction. Even in complex financial transactions, procedural rules on service of summons remain strictly enforced. This case also clarifies important requirements under the Special Purpose Vehicle Act and the limits of rights acquired through loan assignments.

The Facts of the Case

Development Bank of the Philippines (DBP) granted a loan to All Asia Capital and Trust Corporation (All Asia), which then re-lent the amount to Diversified Plastic Film System, Inc. (Diversified). As security, Diversified executed a Mortgage Trust Indenture (MTI) naming All Asia as trustee. All Asia later assigned its rights to DBP, which then assigned a portion of the loan to Philippine Investment One (PI-One).

When Diversified failed to pay, PI-One sought to foreclose on the properties. Diversified challenged PI-One's authority to act as trustee. PI-One then filed a petition for formal appointment as trustee before the Regional Trial Court (RTC). The RTC granted the petition, and the Court of Appeals (CA) affirmed. The Supreme Court reversed.

Jurisdiction Over the Person: The Service of Summons Issue

The Court agreed that the RTC had authority to hear the petition. Since the petition did not involve a specific sum of money or real property, it was classified as incapable of pecuniary estimation, placing it within RTC jurisdiction under Section 19 of Batas Pambansa Blg. 129. The MTI itself also allowed any lender to apply for trustee appointment if the borrower and majority lenders failed to act within two months of a vacancy.

However, the Court found a fatal defect: summons was served on Diversified's receiving officer, not on any person authorized under Section 11, Rule 14 of the Rules of Court. This provision limits service to the corporation's president, managing partner, general manager, corporate secretary, treasurer, or in-house counsel. Citing DOLE Philippines, Inc. (Tropifresh Div.) v. Judge Quilala, the Court emphasized that this enumeration is exclusive, applying the principle expressio unius est exclusio alterius (the express mention of one thing excludes others).

Because service was defective, the RTC never acquired jurisdiction over Diversified. Any proceedings against it were therefore null and void.

Voluntary Appearance vs. Special Appearance

The Court also rejected the argument that Diversified submitted to the RTC's jurisdiction by filing an Answer Ad Cautelam. While voluntary appearance generally confers jurisdiction, a special appearance to challenge jurisdiction is a recognized exception.

Citing Interlink Movie Houses, Inc. v. Court of Appeals, the Court reiterated that a party must unequivocally object to the court's jurisdiction over their person. Diversified consistently raised this objection from the trial court through the CA and up to the Supreme Court. The Answer Ad Cautelam was a preemptive measure against default judgment, filed with an express reservation of jurisdictional objections. This satisfied the requirements for a valid special appearance.

The Assignment Under the Special Purpose Vehicle Act

The Court also examined the validity of the assignment from DBP to PI-One. The Special Purpose Vehicle Act of 2002 sets out requirements for transferring non-performing loans to a Special Purpose Vehicle (SPV), including prior written notice to the borrower and holders of prior encumbrances, plus a certification of eligibility. The exact provision number is not available in the ASG law library, but the requirements themselves were discussed in the ruling.

The Court found no evidence of compliance. The letter informing Diversified of the assignment was executed on the same date as the Deed of Assignment—not prior to it—and there was no proof of a certificate of eligibility. Citing Asset Pool A (SPV-AMC), Inc. v. Court of Appeals, the Court held that these requirements remain necessary for an effective transfer. The assignment was therefore invalid, and PI-One acquired no rights under the MTI.

Limits on an Assignee's Rights

Even assuming a valid assignment, PI-One could not automatically become trustee. The CA relied on provisions of the Special Purpose Vehicle Act that apply rules on subrogation and assignment of credits under the Civil Code. The Supreme Court, citing Casabuena v. Court of Appeals, clarified that an assignee cannot acquire a greater right than that pertaining to the assignor. At most, an assignee can only acquire rights duplicating those which the assignor is entitled by law to exercise.

The MTI required the trustee to be an institution duly authorized to engage in the trust business in Metro Manila. PI-One was not in the trust business and could not comply with this requirement. It was therefore disqualified from serving as trustee, regardless of the assignment's validity.

Practical Takeaways

• Service of summons on corporations must strictly follow Rule 14, Section 11. Serving a receiving officer or any person not listed in the rule is defective and prevents the court from acquiring jurisdiction.
• A special appearance to challenge jurisdiction does not waive objections. Filing a responsive pleading while expressly reserving jurisdictional objections is a valid strategy to avoid default judgment.
• Compliance with the Special Purpose Vehicle Act is mandatory. Prior written notice and certification of eligibility are required before transferring non-performing loans to an SPV.
• Assignees step into the shoes of assignors. They cannot acquire greater rights than their assignor possessed, including qualifications required under a contract.
• Procedural defects can invalidate entire proceedings. Even in complex financial disputes, courts will not overlook jurisdictional requirements.
