Facts

• Respondent Roberto N. Gandionco (the agent) opened a beer dealership for Masbate City with petitioner San Miguel Corporation (SMC) (the third person). (He is the brother-in-law of respondent Gemma Trinidad-Gandionco.)
• Among SMC's standard requirements for a dealership was the posting of sufficient collateral — in money or other valuable property — to secure the beer stocks withdrawn from the company.
• Gandionco did not own property sufficient for the purpose.
• His relatives by affinity — Gemma Trinidad-Gandiongco and the other respondents, collectively the Trinidads (the principals) — executed several special powers of attorney (SPAs) authorising him to offer their properties as collateral. (Four titles were lent over several years — TCT Nos. T-52796, T-5433, T-6347 and T-6346, all in Pamplona, Las Piñas City — each with an identically worded SPA empowering him only "[t]o offer as collateral, security or property bond with [SMC]" the land described. They handed over the original owner's duplicate certificates as well, on the understanding that if SMC accepted a title they themselves would sign whatever documents SMC required.)
• Acting under those SPAs, Gandionco constituted real estate mortgages over the properties in SMC's favour.
• The dealership accumulated a substantial unpaid account. (Roberto paid regularly until August 2007, when eighteen successive post-dated checks were dishonoured, leaving about ₱7,000,000.00 unpaid. SMC then extrajudicially foreclosed and bought in at the sale. The owners learned of the mortgages only in 2008, revoked all four SPAs and wrote SMC — which did not reply.)
• SMC sought to hold both Gandionco and the Trinidads liable for the whole indebtedness.
• The Trinidads, for their part, sought the annulment of the mortgages, contending that they had never intended to answer for Gandionco's business debts. (Civil Case No. 08-0093, to annul the mortgages and the foreclosure sale and to recover their titles. Roberto never answered and was declared in default.)
• Regional Trial Court — mortgages voided. The RTC voided the mortgages and the foreclosure on 28 August 2014, holding that "Roberto's authority is only to offer the subject properties as collateral," and ordered SMC to return the four owner's duplicates.
• Court of Appeals — affirmed. The Court of Appeals dismissed SMC's appeal on 10 October 2017: "a power of attorney must be strictly construed," and to read "to offer" as including the power to mortgage "is to unduly enlarge the term." It deleted the damages awards for want of proof of bad faith.
• Before the Supreme Court. The case reached the Supreme Court on the question of how far the SPAs reached.

Issue

1. Whether the real estate mortgages executed by Gandionco under the SPAs are valid.
2. Whether the Trinidads may be held personally liable for Gandionco's indebtedness to SMC.

Ruling

1. Yes. The mortgages were validly constituted — Gandionco acted within the authority the SPAs conferred.
2. No. The Trinidads are third-party (accommodation) mortgagors§, liable only to the extent of the value secured by the mortgages over their properties, not for the dealership debt itself.

Ratio

• Article 1878 (12)§ requires a special power of attorney to create or convey real rights over immovable property, and a mortgage is such a real right.
• The Trinidads executed precisely that: SPAs empowering Gandionco to offer their properties as collateral.
• He did exactly what he was authorised to do, and the resulting mortgages are valid and binding on the properties.

• The SPAs authorised Gandionco to mortgage the properties — not to contract the dealership, and not to bind the Trinidads as co-debtors.
• Authority conferred by a special power is strictly construed: it extends no further than its terms fairly import, and doubts are resolved against the existence of the broader power.
• The dealership agreement was Gandionco's own contract, entered into in his personal capacity.
• His indebtedness to SMC arose from that contract, to which the Trinidads were strangers.

• A person who mortgages his property to secure another's debt is a third-party or accommodation mortgagor§.
• He is not a party to the principal obligation and does not become a debtor.
• His exposure is confined to the property he has pledged: if the obligation is not paid, the mortgage may be foreclosed and the property sold, but he cannot be pursued for any deficiency, having assumed no personal liability.
• Accordingly, the Trinidads' liability is capped at the amount secured by the mortgages over their properties, and SMC must look to Gandionco personally for the balance.

Doctrine

• Strict construction of special powers. The extent of an agent's authority is measured by the SPA's own terms. Authority to mortgage is not authority to borrow, to contract, or to bind the principal as a co-obligor.
• Article 1878§ (12). Creating or conveying real rights over immovables — including constituting a mortgage — requires a special power of attorney.
• Third-party / accommodation mortgagor. One who secures another's debt with his own property is liable only to the extent of that property. He owes nothing personally and cannot be held for a deficiency after foreclosure.

I. Gist and Central Doctrine

II. Chronological Narration of Material Facts and Procedural Events

1. Respondents Leonara Francisco Vda. de Trinidad, Teodorico F. Trinidad, Gemma Trinidad-Gandionco, Manuel F. Trinidad, and Grace F. Trinidad are the registered co-owners of two parcels of land at Pamplona, Las Piñas City, covered by TCT Nos. T-6346 and T-6347. Respondent Gemma Trinidad-Gandionco is the registered owner of two other parcels, likewise at Pamplona, Las Piñas City, covered by TCT Nos. T-5433 and T-52796.
2. Gemma's brother-in-law, respondent Roberto N. Gandionco, opened a beer dealership for Masbate City with San Miguel Corporation. "One of SMC's standard requirements for a dealership is the submission of sufficient collateral, in money or other valuable properties, to secure the beer stocks to be taken out from SMC."
3. Roberto approached Gemma for help with the collateral requirement. Gemma lent TCT No. T-52796 and allowed Roberto to offer it as collateral.
4. After three months, Roberto approached Gemma again for additional collateral, the value of the first property being insufficient; Gemma acceded and lent TCT No. T-5433.
5. In 2005, Roberto again asked Gemma for another property so he could obtain additional stocks; after obtaining the consent of the Trinidads, TCT No. T-6347 was lent to him.
6. In 2007, for the fourth time, Roberto asked for another property; again with the Trinidads' consent, TCT No. T-6346 was lent to him.
7. On each of these four occasions the registered owners executed a Special Power of Attorney in favour of Roberto, similarly worded and varying only as to the property involved:

"To offer as collateral, security or property bond with [SMC] a parcel of land located at Las Pinas City containing an area of ____ square meters and all improvements thereon and covered by TCT No.____.

HEREBY GIVING AND GRANTING unto my/our said Attorney-in-Fact full power and authority whatsoever requisite necessary to be done in and about the premises as fully to all intents and purposes as I/WE might or could lawfully do if personally present and acting; and

HEREBY RATIFYING AND CONFIRMING all that my/our Attorney-in-Fact shall lawfully do or cause to be done under and by virtue of these presents."

• The owners also delivered to Roberto the original owner's duplicate certificates of title, on four separate occasions over the course of several years.

8. When asked about the status of the titles, Roberto would explain that they were still in SMC's possession, which had yet to decide which title to accept as collateral. "It was the understanding of Gemma and Trinidad, et al., that should SMC accept their certificates of title as collateral, Roberto would bring the necessary documents from SMC which Gemma and Trinidad, et al., would then sign."
9. Using the SPAs, Roberto executed real estate mortgages over the properties covered by TCT Nos. T-6347 and T-5433 in favour of SMC — the mortgages being dated 26 September 2007 and 12 July 2007 as identified in the fallo — and these were annotated on the titles.
10. Roberto availed of beer stocks from SMC, which he regularly paid, until August 2007, when eighteen successive post-dated checks he issued were dishonoured, leaving unpaid obligations of about ₱7,000,000.00.
11. Efforts to collect having failed, SMC extrajudicially foreclosed the mortgages and emerged as the highest bidder at the foreclosure sale.
12. In 2008, Gemma and the Trinidads learned that Roberto's business had closed down and that he had mortgaged two of their properties. They executed four revocations cancelling all the SPAs issued in his favour and wrote SMC informing it of the revocation. No reply was given until they learned of the foreclosure proceedings.
13. Gemma and the Trinidads filed the complaint a quo (Civil Case No. 08-0093) for annulment of mortgage and foreclosure sale and recovery of their titles. Roberto did not file any answer and was declared in default.
14. On 28 August 2014, the RTC voided the mortgages and the extrajudicial foreclosure, holding that "Roberto's authority is only to offer the subject properties as collateral" and that "SMC should have been placed on guard by the fact that the SPAs were long executed before the REMs were entered into." It ordered SMC to return the owner's duplicates of TCT Nos. T-6346, T-6347, T-5433 and T-52796 and to pay moral damages, attorney's fees and costs, and dismissed SMC's cross-claim against Roberto for failure to prove his liability, SMC having presented no receipts and having relied merely on the Certificate of Sale. Reconsideration was denied.
15. On 10 October 2017, the CA dismissed SMC's appeal, holding that "a power of attorney must be strictly construed," that the SPAs "merely authorized Roberto to offer the subject properties as collateral, but not to enter into a mortgage contract," and that "to interpret the SPAs as likewise giving Roberto the power to mortgage the property is to unduly enlarge the term 'to offer.'" It sustained the denial of the cross-claim and deleted the awards of ₱500,000.00 moral damages and ₱300,000.00 attorney's fees and costs for lack of proof of bad faith. Reconsideration was denied on 14 February 2018.
16. On 28 July 2020, the Supreme Court rendered its Decision on the Rule 45 petition, partly granting it, with a Concurring Opinion by Caguioa, J.

V. Ruling / Disposition (Categorical, Issue-Mapped)

"WHEREFORE, the petition is PARTLY GRANTED. The Decision dated October 10, 2017 and Resolution dated February 14, 2018 of the Court of Appeals insofar as it declared the real estate mortgages dated September 26, 2007 and July 12, 2007 and the consequent extrajudicial foreclosure sales as void, ordered petitioner San Miguel Corporation to return to respondents their owner's duplicate copies of Transfer Certificates of Title Nos. T-6347 and T-5433, and dismissed San Miguel Corporation's cross-claim against Roberto Gandionco, are REVERSED and SET ASIDE.

San Miguel Corporation's prayer for award of moral damages (in the amount of P500,000.00), exemplary damages (in the amount of P100,000.00), and attorney's fees and litigation expenses (in the amount of P600,000.00) is DENIED for lack of merit.

For the purpose of determining the exact amount of respondent Roberto Gandionco's outstanding liability to San Miguel Corporation, if there is any, the case is hereby REMANDED to the Regional Trial Court of Las Piñas City.

SO ORDERED."

VI. Ratio Decidendi and Doctrines (Topic-Focused)

A. Ratio Decidendi (Decisive Reasoning)

• The ruling proceeds under two internal sub-headings.
• The first — quoted in Section IV-A above — is the sub-holding matching the Topic/Subtopic, and Steps 1 to 6 track it.
• Step 1 — The requisites of a valid mortgage, and the isolation of the operative one. "For a contract of mortgage to be valid, the following essential requisites must be met: first, that the mortgage is constituted to secure the fulfillment of a principal obligation; second, the mortgagor is the absolute owner of the thing mortgaged; and third, the persons constituting the mortgage have the free disposal of their property, and in the absence thereof, that they be legally authorized for the purpose. Third persons not parties to the principal obligation may secure such obligation by mortgaging their own property."
• (Footnote 15 anchors this to Article 2085.
• Applied: since the owners "were not the ones who personally mortgaged their properties to secure Roberto's obligations with SMC, the query to be had is whether Roberto was legally authorized to do so."
• Step 2 — The codal requirement of a special power (Article 1878§). "Article 1878§ of the Civil Code requires an SPA in cases where real rights over immovable property are created or conveyed."
• Footnote 16 reproduces the entire enumeration of Article 1878§, with paragraph (12) — "To create or convey real rights over immovable property" — italicised by the Court.
• Note that the Court's own emphasis identifies (12), not (5) and not Article 1879§, as the operative paragraph.
• Step 3 — The interpretive rule (Article 1370). "The language of the subject SPAs are clear and unambiguous. In interpreting contracts, Article 1370 of the Civil Code unequivocally provides that 'if the terms of a contract are clear and leave no doubt upon the intention of the contracting parties, the literal meaning of its stipulations shall control.' This is similar to the 'plain meaning rule' which assumes that the intent of the parties to an instrument is 'embodied in the writing itself, and when the words are clear and unambiguous the intent is to be discovered only from the express language of the agreement.'"
• (Citing Norton Resources and Development Corporation v. All Asia Bank Corporation, itself citing Benguet Corporation v. Cabildo.)
• Step 4 — The construction adopted, against the CA. "Contrary to the CA's ruling, the phrase 'to offer' the subject properties 'as collateral, security or property bond with SMC,' coupled with the 'full power and authority' to do all that is necessary for all intents and purposes of the contract, is a specific and express authority to mortgage the subject properties in favor of SMC."
• Step 5 — The purposive reason. "This is so considering that the presentation of the TCTs by Roberto to SMC was for the purpose of complying with the collateral requirement for the dealership. As such, executing the real estate mortgages and registering the same with the register of deeds are well within the scope of the authority granted."
• The power is thus read against the transaction it was created to serve.
• Step 6 — The principals' private understanding is irrelevant to SMC (Article 1900; Article 1902). "It is of no moment that it was the supposed 'understanding' of the registered owners that 'should SMC accept their certificates of title as collateral, Roberto would bring the necessary documents from SMC which [the registered owners] would then sign.'"
• The Court reproduced Article 1900 — "So far as third persons are concerned, an act is deemed to have been performed within the scope of the agent's authority, if such act is within the terms of the power of attorney, as written, even if the agent has in fact exceeded the limits of his authority according to an understanding between the principal and the agent" — and Article 1902 — "Private or secret orders and instructions of the principal do not prejudice third persons who have relied upon the power of attorney or instructions shown to them."
• Step 7 — The alternative holding: apparent authority. "Assuming, however, that Roberto exceeded the limits of his authority under the SPA and such unauthorized acts were not ratified ... the latter are still bound by the mortgages entered by Roberto under the doctrine of apparent authority."
• Quoting Woodchild Holdings, Inc. v. Roxas Electric and Construction Co., Inc.: "apparent authority is based on estoppel and can arise from two instances: first, the principal may knowingly permit the agent to so hold himself out as having such authority ...; second, the principal may so clothe the agent with the indicia of authority as to lead a reasonably prudent person to believe that he actually has such authority. ... The apparent power of an agent is to be determined by the acts of the principal and not by the acts of the agent."
• And the three-element burden: "(a) the acts of the respondent justifying belief in the agency by the petitioner; (b) knowledge thereof by the respondent which is sought to be held; and, (c) reliance thereon by the petitioner consistent with ordinary care and prudence."
• Step 8 — The indicia relied upon. "[I]n addition to executing similarly worded SPAs expressly authorizing Roberto to offer specific properties as collateral and to do all things necessary in furtherance of said purpose, Gemma and Trinidad, et al., delivered their original owner's duplicate TCTs to Roberto. This happened not only once, but even on four separate occasions, and this made possible the execution of the mortgages on two of the properties, their registration, and the delivery by SMC of beer stocks to Roberto."
• Applying Domingo v. Robles "by analogy": "The registered owner who places in the hands of another an executed document of transfer of registered land effectively represents to a third party that the holder of such document is authorized to deal with the property."
• Step 9 — The owners' own want of diligence, and the equitable maxim. "Furthermore, Gemma and Trinidad, et al. did not exercise even the slightest diligence to ascertain the whereabouts of their owner's duplicate TCTs, but instead relied on Roberto's explanation that the titles were still in SMC's possession... They only revoked the SPAs ... upon receiving news that Roberto's business had closed down."
• Hence: "as between two innocent persons, one of whom must suffer the consequences of a breach of trust, the one who made it possible by his act of confidence must bear the loss."
• Step 10 — Extent of the accommodation mortgagors' liability, and remand. "There is x x x no legal provision nor jurisprudence in our jurisdiction which makes a third person who secures the fulfillment of another's obligation by mortgaging his own property to be solidarily bound with the principal obligor... And the liability of the third-party mortgagors extends only to the property mortgaged. Should there be any deficiency, the creditor has recourse on the principal debtor."
• Because "the amount secured by the mortgages, as well as SMC's bid in the foreclosure sale, are not specified in the pleadings," the case was remanded on that single point.

B. Doctrines / Rules / Principles Laid Down

1. A special power "to offer as collateral," with full power to do all things necessary, is authority to mortgage — the doctrinal takeaway for this Topic/Subtopic. Verbatim:

   "Contrary to the CA's ruling, the phrase 'to offer' the subject properties 'as collateral, security or property bond with SMC,' coupled with the 'full power and authority' to do all that is necessary for all intents and purposes of the contract, is a specific and express authority to mortgage the subject properties in favor of SMC."

2. A special power of attorney is required to create or convey real rights over immovables (Article 1878§(12)). The Court italicised paragraph (12) in its own footnoted reproduction of the article.
3. A power of attorney whose terms are clear is read by the plain-meaning rule (Article 1370). "[I]f the terms of a contract are clear and leave no doubt upon the intention of the contracting parties, the literal meaning of its stipulations shall control."
4. The written terms govern as to third persons; private understandings do not (Article 1900; Article 1902). Verbatim:

   "So far as third persons are concerned, an act is deemed to have been performed within the scope of the agent's authority, if such act is within the terms of the power of attorney, as written, even if the agent has in fact exceeded the limits of his authority according to an understanding between the principal and the agent."

• And: "Private or secret orders and instructions of the principal do not prejudice third persons who have relied upon the power of attorney or instructions shown to them."

5. Apparent authority: two sources, three elements (Woodchild Holdings). Estoppel arising either from knowingly permitting the agent to hold himself out, or from clothing him with indicia of authority; provable by (a) acts of the principal justifying belief, (b) the principal's knowledge, and (c) reliance consistent with ordinary care and prudence. "The apparent power of an agent is to be determined by the acts of the principal and not by the acts of the agent."
6. Delivery of the owner's duplicate certificate of title is itself a representation of authority (Domingo v. Robles, applied by analogy). "The registered owner who places in the hands of another an executed document of transfer of registered land effectively represents to a third party that the holder of such document is authorized to deal with the property."
7. Equitable allocation of loss. "[A]s between two innocent persons, one of whom must suffer the consequences of a breach of trust, the one who made it possible by his act of confidence must bear the loss."
8. Accommodation mortgagors are not solidarily bound; their liability is limited to the property mortgaged, with recourse for any deficiency against the principal debtor.

C. Distinctions / Limitations / Qualifications

1. The Court did not cite Article 1879§, and this must be stated plainly. The syllabus places the case under "Power to sell and power to mortgage (Art. 1879§)," and the case is indeed about whether one power over an immovable carries another. But the decision's codal anchors are Article 1878§(12), Article 1370, Article 1900, Article 1902 and Article 2085. Any statement that the Court applied Article 1879§ would be an invention. The connection between this holding and Article 1879§ drawn in Section VI-D below is a pedagogical inference and is labelled as such.
2. The direction of the construction is enlarging, not restricting — which is the tension worth flagging. Article 1879§ and the strict-construction rule of Angeles v. PNR (Week 2) ("[t]he instrument will be held to grant only those powers which are specified therein") both cut against reading powers into a grant. The CA applied exactly that reasoning and was reversed. The reconciliation the Court offers is that "to offer as collateral" is not a different power from mortgaging but the same power described by its purpose — the grant being read together with "full power and authority whatsoever requisite necessary" and with the collateral requirement it was made to satisfy. A student should be ready to state both sides.
3. Two independent grounds support the result. The first is construction of the written power (Steps 3-6); the second is apparent authority (Steps 7-9), expressly offered as an assumption arguendo. A recitation should keep them separate: the first is a Week 2(c) holding, the second belongs with Article 1911§ and Week 5.
4. The delivery of the original owner's duplicates did decisive work. Caguioa, J., expands this into the ground of his separate concurrence (Section VII). Even in the ponencia the repeated physical delivery — four times over several years — is what converts a paper grant into a representation to the world.
5. The holding is bounded by the identity of the transaction. The SPAs named SMC as the counterparty and named the specific titled parcels. The Court's purposive reading — "the presentation of the TCTs by Roberto to SMC was for the purpose of complying with the collateral requirement for the dealership" — would not obviously extend to a mortgage in favour of a stranger or over other property.
6. The owners' revocations came too late and are given no effect, the mortgages having been constituted and annotated before 2008.

D. Topic/Subtopic Integration (Mandatory)

• The classification is ANALOGOUS.
• Article 1879§ embodies the principle that special powers over an immovable are not interchangeable and are not enlarged by implication: a power to sell excludes the power to mortgage, and vice versa.
• San Miguel Corporation v. Trinidad presents the same species of question — does this special power reach that act? — and answers it, but by a different route and with the opposite tendency.
• This is an inference drawn for study purposes and not a statement of the Court's own reasoning: the case is best used to mark the boundary of the Article 1879§ principle.
• The strictness of Article 1879§ operates where the two powers are genuinely distinct juridical acts (selling versus mortgaging), because each disposes of the owner's patrimony differently.
• It does not operate where the words used are merely a lay description of the very act performed — and the Court held "to offer as collateral, security or property bond" to be exactly that: the layman's way of saying "to mortgage," reinforced by the phrase "full power and authority whatsoever requisite necessary" and by the purpose the grant was made to serve.
• Two further lessons for Week 2(c) follow, and both are the Court's own.
• First, the written terms control as against third persons: under Article 1900 an act within the terms of the power as written is within the agent's authority "even if the agent has in fact exceeded the limits of his authority according to an understanding between the principal and the agent," and under Article 1902 "[p]rivate or secret orders and instructions of the principal do not prejudice third persons."
• Second, formalities are not exhausted by the paper: handing over the original owner's duplicate certificates of title is itself a representation of authority, and doing so four times over several years without ever asking where they had gone is the "act of confidence" that made the loss the owners' to bear.
• Recite this case beside [Commoner Lending v. Sps.
• Villanueva](/agency-trust-partnership/week-02/commoner-lending-corp-v-sps-villanueva), which reaches the opposite result on a differently worded grant.

VII. Separate Opinions
