Piansay v. David

G.R. No. L-19468 · October 30, 1964 · Supreme Court

b. Immovable Property (Art. 415) — Kinds of real properties

Gist

The case involves a complaint for injunction and declaration of ownership over a residential house that was the subject of a chattel mortgage, a subsequent foreclosure sale, and a later levy by a third-party creditor. The Supreme Court affirmed the lower court's dismissal of the complaint, holding that the petitioners were barred by the principle of res judicata and lacked a cause of action.

Core Doctrine

The central doctrine is that buildings are immovables by nature, being accessories to the land; consequently, while a chattel mortgage over a building may be valid between the contracting parties based on estoppel, it is null and void as to third persons.

Facts

On December 11, 1948, Conrado S. David executed a chattel mortgage over his house at 1259 Sande Street, Tondo, Manila, in favor of Claudia Vda. de Uy Kim to secure a P3,000.00 loan. The mortgage was registered in the Chattel Mortgage Registry of Manila on December 19, 1948.
Upon David’s default, the house was sold at public auction to Uy Kim on February 10, 1953, to satisfy the debt. On March 22, 1954, Uy Kim sold the house to petitioner Salvador Piansay.
Prior to these events, the same house had been mortgaged to respondent Marcos Mangubat. On March 1, 1956, Mangubat filed a collection suit (Civil Case No. 29078) against David, later amending the complaint to include Piansay and Uy Kim as defendants and seeking the annulment of the 1953 auction sale. The trial court in that case ordered David to pay Mangubat but dismissed the complaint as to Piansay and Uy Kim.
On appeal (CA-G.R. No. 21797-R), the Court of Appeals (CA) ruled that because the house was real property, the registration of the chattel mortgage was a "futile act" and produced no legal effect. The CA held that Uy Kim acquired no rights from the sheriff's sale and therefore could not validly sell the house to Piansay.
When the records were remanded, Mangubat moved to levy execution upon the house. Piansay moved to set aside the levy, but Judge Jesus Y. Perez denied the motion on February 4, 1961, ruling that the house remained the property of David because the prior mortgage and sale did not transmit any right to Uy Kim. Piansay’s petition for certiorari to the CA (CA-G.R. No. 28974-R) was denied on March 3, 1961.
On July 31, 1961, Piansay and Uy Kim filed the present action (Civil Case No. 47664) against David and Mangubat to declare Piansay the lawful owner and enjoin the auction sale. Mangubat moved to dismiss on grounds of res judicata and lack of personality. The trial court granted the dismissal, leading to the instant appeal.

Issue

Whether a chattel mortgage constituted over a building of strong materials is valid and binding against third persons who are not parties to the contract.

Secondary issues. Whether the current action is barred by the principle of res judicata.

Ruling

Main issue. NO — the chattel mortgage over the building is void as against third persons. A building is real property, an accessory of the land under omne quod solo inaedificatur solo cedit, so registering it in the chattel registry is a futile act "where the interest conveyed is in the nature of real property." The parties themselves may be estopped by their agreement to treat the house as personalty, but that estoppel "cannot and does not bind third persons, who are not parties to the aforementioned contract or their privies." Mangubat was a stranger to the mortgage, so as to him the foreclosure sale was "null and void," Uy Kim acquired no dominical right, and she had none to pass to Piansay.

Secondary issues. YES — the action is barred. The earlier orders denying Piansay's motion to set aside the levy had already become final and executory, so the validity of the chattel mortgage and of the sale under it could not be relitigated in this suit.

"WHEREFORE, the others appealed from are hereby affirmed, with costs against plaintiffs Salvador Piansay and Claudia B. Vda. de Uy Kim. It is so ordered."

Ratio

The Court’s reasoning is anchored on the fundamental classification of property.
Under Philippine law, buildings are regarded as accessories to the land.
Applying the Roman maxim omne quod solo inaedificatur solo cedit, the Court reasons that accessories must partake of the nature of the principal thing (the land).
Consequently, since a building is real property, any attempt to convey or encumber it through the Chattel Mortgage Registry is ineffective against third parties.
The Court emphasizes that "where the interest conveyed is in the nature of real property, the registration of the document in the registry of chattels is merely a futile act".
The Court further distinguishes the effect of such contracts between the immediate parties versus third persons.
While the contracting parties (David and Uy Kim) might be bound by their agreement to treat the house as personalty under the principle of estoppel, this "cannot and does not bind third persons, who are not parties to the aforementioned contract or their privies".
Because Mangubat was not a party to the mortgage, the foreclosure sale was "null and void insofar as defendant Mangubat is concerned" and Uy Kim acquired no dominical rights to transmit to Piansay.
Finally, the Court ruled that the petitioners were barred from re-litigating the validity of the mortgage and sale because the previous court orders denying Piansay's motion to set aside the levy had become final and executory.

Doctrine

Immovable Character of Buildings: Buildings are real property by nature as they are accessories to the soil.
Registration Efficacy: Registration of real property in the Chattel Mortgage Registry is a "futile act" and does not produce the legal effects of registration in the Registry of Property.
Limited Scope of Estoppel: A contract treating real property as personalty is valid only between the parties but is void as to third persons.
Invalidity of Derivative Title: A buyer at a foreclosure sale of a void chattel mortgage over real property acquires no title and cannot validly transmit ownership to an assignee.

The doctrine of estoppel allows contracting parties to treat an immovable as a chattel as between themselves, but this is an exception to the general rule of property classification and cannot prejudice third parties.

Mangubat moved to dismiss on grounds of res judicata and lack of personality.
The trial court granted the dismissal, leading to the instant appeal.

III. Arguments of the Parties

A. Petitioner/Prosecution

Petitioners argued that Piansay is the true and lawful owner of the house, having purchased it from Uy Kim. They contended that the chattel mortgage was validly registered and the subsequent foreclosure sale transmitted ownership, thus Mangubat had no right to levy upon the property to satisfy a judgment against David.

B. Respondent/Defense

Mangubat argued that the action was barred by the principle of res judicata following the finality of the orders in Civil Case No. 29078. He further contended that petitioners lacked the personality to bring the action because the CA had already determined that the house was real property and that the chattel mortgage and subsequent sale were void as to third persons.

C. Common Ground

Both Uy Kim and Mangubat were creditors of the same debtor, Conrado David.

Cited Laws & Provisions

Every statute, rule, and issuance the decision turns on — the text as written, and the work it does in this case.

Civil Code

Article 415, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book II (Property, Ownership, and Its Modifications), Title I (Classification of Property), Chapter 1 (Immovable Property)

The following are immovable property:

(1) Land, buildings, roads and constructions of all kinds adhered to the soil;

(2) Trees, plants, and growing fruits, while they are attached to the land or form an integral part of an immovable;

(3) Everything attached to an immovable in a fixed manner, in such a way that it cannot be separated therefrom without breaking the material or deterioration of the object;

(4) Statues, reliefs, paintings or other objects for use or ornamentation, placed in buildings or on lands by the owner of the immovable in such a manner that it reveals the intention to attach them permanently to the tenements;

(5) Machinery, receptacles, instruments or implements intended by the owner of the tenement for an industry or works which may be carried on in a building or on a piece of land, and which tend directly to meet the needs of the said industry or works;

(6) Animal houses, pigeon-houses, beehives, fish ponds or breeding places of similar nature, in case their owner has placed them or preserves them with the intention to have them permanently attached to the land, and forming a permanent part of it; the animals in these places are included;

(7) Fertilizer actually used on a piece of land;

(8) Mines, quarries, and slag dumps, while the matter thereof forms part of the bed, and waters either running or stagnant;

(9) Docks and structures which, though floating, are intended by their nature and object to remain at a fixed place on a river, lake, or coast;

(10) Contracts for public works, and servitudes and other real rights over immovable property. (334a)

Why it is cited here

Paragraph (1) settles the classification: "Land, buildings, roads and constructions of all kinds adhered to the soil."

Buildings are listed by name, without qualification. They are immovable by nature, as accessories to the land, and nothing about who owns them or what the parties call them changes that.

The consequence for security is direct. A chattel mortgage is a device for personal property; an immovable must be mortgaged by real estate mortgage and registered as such. A chattel mortgage over a building is therefore the wrong instrument for the thing it purports to cover.

Its effect splits accordingly. Between the contracting parties it may be upheld on estoppel — they agreed to it and cannot disown it. As to third persons it is null and void, because they were entitled to look in the register appropriate to an immovable, and the parties' private characterisation cannot be made to bind people who never consented to it.

This is the mirror image of Sergs Products: there the estoppel let the agreement be enforced between the parties; here the same principle stops short at exactly the same boundary.

Civil Code

Article 414, Civil Code

Civil Code of the Philippines (R.A. No. 386), Book II (Property, Ownership, and Its Modifications), Title I (Classification of Property)

All things which are or may be the object of appropriation are considered either:

(1) Immovable or real property; or

(2) Movable or personal property. (333)

Why it is cited here

The binary that makes the wrong choice of instrument fatal rather than merely irregular: property is either immovable or movable.

Because there is no third category and no hybrid, an instrument designed for one kind cannot half-work on the other. The registration systems are separate, the formalities are separate, and the notice each gives to the world is separate — so a chattel mortgage over a building registers nothing that a person searching the land records would find.

That, and not any technicality, is why third persons are unaffected by it.

Upon David’s default, the house was sold at public auction to Uy Kim on February 10, 1953, to satisfy the debt. On March 22, 1954, Uy Kim sold the house to petitioner Salvador Piansay.

On July 31, 1961, Piansay and Uy Kim filed the present action (Civil Case No. 47664) against David and Mangubat to declare Piansay the lawful owner and enjoin the auction sale. Mangubat moved to dismiss on grounds of res judicata and lack of personality. The trial court granted the dismissal, leading to the instant appeal.
