G.R. No. L-41555 - Industrial Fice Corp. vs. Tobias

On June 16, 1968, respondent Castor Tobias purchased one (1) Dodge truck on installment from Leelin Motors, Inc.
To finance the purchase, respondent executed a promissory note for P29,070.28, payable in 36 equal installments with an interest rate of 12% per annum.
To secure the promissory note, a chattel mortgage on the Dodge truck was executed in favor of Leelin Motors, Inc.

On June 19, 1969, Leelin Motors, Inc. indorsed the promissory note and assigned both this note and the chattel mortgage to the petitioner, Industrial Finance Corporation.
Respondent made six (6) installments directly to petitioner, with the last payment on February 19, 1970, leaving a substantial unpaid balance.

On May 14, 1970, petitioner’s counsel sent a letter demanding payment of the arrears (P4,254.65) and the remaining balance (P25,249.65) on or before May 24, 1970, or the surrender of the truck.
The demand letter explicitly warned that failure to comply would lead to legal action, including claims for damages and attorney’s fees.
At that time, respondent was already in arrears on more than two installment payments.
On May 27, 1970, respondent replied, voluntarily offering to surrender the truck. In his letter, he cited:

The truck’s involvement in an accident (noted to have occurred in the later part of February) which rendered the vehicle less valuable and repair delayed.
His dissatisfaction with the quality and progress of repairs.
An appeal that if he surrendered the truck, his name would not be adversely affected in the credit division.

Upon learning of the accident and subsequent issues with the truck, petitioner decided against retrieving the truck from Leelin Motors, Inc.
On February 16, 1971, petitioner initiated legal action in the Court of First Instance of Manila to recover the unpaid balance of the promissory note.
The lower court dismissed the complaint on the grounds that respondent had voluntarily surrendered the truck by complying with petitioner’s demand.
The Court of Appeals subsequently affirmed the dismissal but modified the decision by ordering respondent to pay the cost of repairs (P5,396.78 plus interest).

Petitioner argued that as an unpaid vendor under Article 1484 of the New Civil Code, it retained the option to exact fulfillment of the obligation despite having offered the alternative of surrendering the truck.
Respondent contended that petitioner was estopped from claiming the balance when it had effectively chosen to demand the truck’s surrender, which the respondent executed.
The dispute centered on the interpretation and application of Article 1484, which provides alternative remedies in installment sales contracts.

Whether the petitioner, as an unpaid vendor under Article 1484 of the New Civil Code, is precluded from pursuing the remedy of exact fulfillment of the obligation after offering the option to surrender the truck.
Whether respondent’s voluntary act of surrendering the truck—coupled with his reasons for doing so—effectively barred the petitioner from claiming the unpaid balance of the promissory note.
Whether the prior demand for surrender of the truck by petitioner, and respondent’s subsequent acceptance of that offer in his correspondence, constitutes an estoppel that prevents petitioner from later claiming exact fulfillment of the obligation.
