California Bus Lines, Inc. vs. State Investment House, Inc.

A restructuring agreement that expressly recognizes the continuing existence and validity of prior promissory notes and merely changes the terms of payment or adds compatible obligations does not constitute extinctive novation. Furthermore, a compromise agreement cannot supersede or discharge promissory notes previously assigned to a third party, as the assignor loses the authority to compromise the assigned notes without a special power of attorney, and the compromise binds only the parties to it.

Delta Motors Corporation (Delta) obtained a credit line from respondent State Investment House, Inc. (SIHI), securing it with a Continuing Deed of Assignment of Receivables. Separately, petitioner California Bus Lines, Inc. (CBLI) purchased buses from Delta, executing 16 promissory notes and chattel mortgages. CBLI defaulted, prompting a restructuring agreement with Delta that modified the payment schedule and added a management takeover clause. Subsequently, Delta assigned five of these promissory notes to SIHI to satisfy its own obligations. SIHI demanded payment from CBLI. Later, Delta and CBLI entered a compromise agreement in a separate injunction case, resulting in the extrajudicial foreclosure of the chattel mortgages. SIHI then sued CBLI to collect on the five assigned notes.

• The Credit Agreements: Delta Motors Corporation (Delta) obtained a ₱25,000,000 credit line from State Investment House, Inc. (SIHI) under three credit agreements in 1979, eventually becoming indebted to SIHI for ₱24,010,269.32. Delta secured this with a Continuing Deed of Assignment of Receivables.
• The Bus Purchase and Promissory Notes: From 1979 to 1980, California Bus Lines, Inc. (CBLI) purchased 35 buses from Delta, executing 16 promissory notes and chattel mortgages in favor of Delta.
• Default and Restructuring: CBLI defaulted, leading to a restructuring agreement on October 7, 1981. The agreement modified the payment schedule (daily remittance), increased the interest rate to 16% p.a., added fees, and granted Delta a management takeover option in case of further default. Paragraph 8 of the agreement expressly stated that the terms of the promissory notes would continue to govern the relationship.
• Assignment to SIHI: On December 23, 1981, Delta assigned its receivables to SIHI. On September 15, 1983, Delta executed a Deed of Sale assigning five of the 16 promissory notes to SIHI. SIHI demanded direct payment from CBLI on December 13, 1983.
• The Compromise Agreement: CBLI continued to default, leading Delta to threaten a management takeover. CBLI filed an injunction case (Civil Case No. 0023-P). On July 24, 1984, Delta and CBLI entered a compromise agreement stipulating the extrajudicial foreclosure of the chattel mortgages as full settlement of their rights and obligations.
• Subsequent Foreclosures: Delta foreclosed on the chattel mortgages, purchasing 14 buses at auction on April 2, 1987. Separately, SIHI levied on execution on the same 14 buses in a different case against Delta, purchasing them at auction on April 7, 1987.
• The Collection Suit: On December 26, 1984, SIHI sued CBLI to collect on the five assigned promissory notes. The RTC dismissed the complaint, finding novation. The Court of Appeals reversed, prompting CBLI's petition to the Supreme Court.

• Novation by Restructuring Agreement: CBLI argued that the restructuring agreement did not merely change incidental elements but increased obligations and added new ones incompatible with the old promissory notes, thereby extinguishing them.
• Discharge by Compromise Agreement: CBLI maintained that the 1984 compromise agreement in Civil Case No. 0023-P superseded and discharged the promissory notes, operating as res judicata since it settled all rights and obligations.
• Estoppel by Non-Intervention: CBLI contended that SIHI was estopped from questioning the compromise agreement because it failed to intervene in Civil Case No. 0023-P after being informed of the management takeover.
• Prohibition on Deficiency Claims under Art. 1484(3): CBLI asserted that SIHI, as successor-in-interest, could no longer recover on the notes because Delta had already extrajudicially foreclosed on the chattel mortgages, barring a deficiency claim under Article 1484(3) of the Civil Code.
• Invalidity of Attachment: CBLI claimed there was no basis for the writ of preliminary attachment, as it committed no fraud in contracting the obligation and did not fraudulently dispose of its properties.

• No Novation: SIHI implicitly argued that the restructuring agreement did not novate the notes, as it expressly ratified the old obligations.
• Compromise Does Not Bind Assignee: SIHI maintained that the compromise agreement between Delta and CBLI could not bind it, as it was not a party to it and Delta had no authority to compromise the assigned notes.
• Validity of Attachment: SIHI asserted the validity of the preliminary attachment, which had already been upheld by the Court of Appeals in a prior final ruling.

• Novation: Whether the restructuring agreement between CBLI and Delta novated the five promissory notes assigned to SIHI.
• Compromise Agreement: Whether the compromise agreement between CBLI and Delta in Civil Case No. 0023-P superseded and discharged the five promissory notes assigned to SIHI.
• Art. 1484(3) Applicability: Whether Article 1484(3) of the Civil Code prohibits SIHI from recovering on the promissory notes after Delta's extrajudicial foreclosure of the chattel mortgages.
• Validity of Attachment: Whether the writ of preliminary attachment issued against CBLI's properties was valid.

• Novation: The restructuring agreement did not novate the promissory notes. Novation is never presumed and requires either an express declaration of extinguishment or complete incompatibility between the old and new obligations. The restructuring agreement expressly ratified the old promissory notes in paragraph 8 and merely provided a new schedule of payments and additional security. Changes in payment terms and the addition of compatible obligations do not constitute extinctive novation.
• Compromise Agreement: The compromise agreement did not supersede or discharge the assigned promissory notes. Delta had no authority to compromise the five notes after assigning them to SIHI; Article 1878 of the Civil Code requires a special power of attorney to compromise, which was absent. Furthermore, a compromise agreement binds only the parties to it. SIHI was not a party, and the agreement expressly covered only the rights and obligations of Delta and CBLI.
• Estoppel by Non-Intervention: SIHI was not estopped from pursuing its claim. The assignment of the notes separated CBLI's obligations to SIHI from the pending case involving the remaining notes. Intervention is permissive, not mandatory, and the judgment in the compromise case did not operate as res judicata due to a lack of identity of parties and subject matter.
• Art. 1484(3) Applicability: Article 1484(3) finds no application. Delta's extrajudicial foreclosure could not prejudice SIHI's rights, as the assignment created a separate and independent obligation. CBLI knew of the assignment and Delta's lack of authority, yet agreed to the foreclosure.
• Validity of Attachment: The validity of the preliminary attachment was already resolved with finality by the Court of Appeals in CA-G.R. SP No. 08376, precluding re-litigation of the issue. Moreover, a claim for damages resulting from attachment cannot be sustained where the requesting party acted in good faith and without malice.

• Novation — Defined as the extinguishment of an obligation by the substitution or change of the obligation by a subsequent one. It may be extinctive (old obligation terminated) or modificatory (old obligation subsists to the extent compatible). For extinctive novation to occur, there must be: (1) a previous valid obligation; (2) an agreement of all parties to a new contract; (3) the extinguishment of the old obligation; and (4) the birth of a valid new obligation. Novation is never presumed; the animus novandi must appear by express agreement or unequivocal acts. In this case, the restructuring agreement was merely modificatory because it expressly ratified the old promissory notes and contained no irreconcilable incompatibility with them.
• Incompatibility Test for Novation — The test of incompatibility is whether the two obligations can stand together, each having its independent existence. If they cannot, they are incompatible and the latter novates the first. Changes must be essential (object, cause, principal conditions), not merely accidental. For monetary obligations, an instrument that expressly recognizes the old, changes only payment terms, or adds compatible obligations does not novate.
• Relativity of Compromise Agreements — A compromise agreement determines the rights and obligations of only the parties to it. It cannot bind third persons who are not parties to the agreement.
• Authority to Compromise — Under Article 1878(3) of the Civil Code, an agent requires a special power of attorney to compromise the rights of the principal. Absent such special authority, a compromise executed by an agent does not bind the principal.

• "Novation is never presumed, and the animus novandi, whether totally or partially, must appear by express agreement of the parties, or by their acts that are too clear and unequivocal to be mistaken."
• "The test of incompatibility is whether the two obligations can stand together, each one having its independent existence. If they cannot, they are incompatible and the latter obligation novates the first."
• "Where the parties to the new obligation expressly recognize the continuing existence and validity of the old one, there can be no novation."

• Inchausti & Co. v. Yulo, 34 Phil. 978 (1914) — Followed. Held that an obligation to pay a sum of money is not novated by a new instrument that ratifies the old, changes only the term of payment, and adds other obligations not incompatible with the old one.
• Tible v. Aquino, No. L-28967, 22 July 1975, 65 SCRA 207 — Followed. Declared that a mere extension of payment and the addition of another obligation not incompatible with the old one is not a novation.
• Young v. CA, G.R. No. 83271, 8 May 1991, 196 SCRA 795 — Followed. Ruled that a change in the incidental elements of, or an addition of such element to, an obligation, unless otherwise expressed by the parties, will not result in its extinguishment.
• Guerrero v. Court of Appeals, No. L-22366, 30 October 1969, 29 SCRA 791 — Followed. Stated the settled rule that a compromise agreement determines the rights and obligations of only the parties to it.
• Tropical Homes, Inc. v. Court of Appeals, G.R. No. 111858, 14 May 1997, 272 SCRA 428 — Followed. Held that an agreement providing a different schedule and manner of payment to restructure an outstanding obligation is not tantamount to novation.

• Article 1484(3), Civil Code — Prohibits a vendor from suing for the deficiency after foreclosing on a chattel mortgage in a sale payable in installments. The Court held this provision inapplicable because the assignment of the notes created a separate and independent obligation, and the foreclosure by Delta could not prejudice SIHI's distinct right to collect.
• Article 1878(3), Civil Code — Requires a special power of attorney for an agent to compromise, submit questions to arbitration, renounce the right to appeal, waive objections to venue, or abandon a prescription already acquired. The Court applied this to hold that Delta's limited authority to collect for SIHI did not include the power to compromise CBLI's obligations on the assigned notes.
• Section 19, Rule 3, Rules of Court — Governs the transfer of interest pendente lite, allowing the action to continue by or against the original party unless the court directs substitution. The Court noted that the assignment of the notes during the pendency of Civil Case No. 0023-P meant SIHI's rights were separate, and the judgment in that case would not prejudice SIHI as a non-party.
• Section 1, Rule 19, 1997 Rules of Civil Procedure (formerly Sec. 2, Rule 12, 1988 Revised Rules) — Governs intervention, providing that a person with a legal interest may be allowed to intervene. The Court cited this to emphasize the permissive, not mandatory, nature of intervention, ruling that SIHI's failure to intervene did not estop it from filing a separate action.
