G.R. No. L-5054 - Garcia vs. De los Santos

On September 9, 1944, the defendants executed a promissory note in favor of the plaintiff for P10,000 with an interest rate of 10% per annum.
As security for the note, the defendants also constituted a mortgage on a piece of land in the City of Manila.
The note contained the stipulation that interest and principal "shall be made in full whatever legal tender and currency is prevailing and in use at the time such interests or the obligation becomes due and payable."

The promissory note was due "four years after date" but remained unpaid except for a partial payment of P500 in 1946.
As a consequence of non-payment, the plaintiff initiated an action for foreclosure of the mortgage.
A judgment was rendered in favor of the plaintiff for the sum due under the note, plus an additional P600 for attorney's fees and costs.

Defendants, as appellants, raised several errors on appeal including issues related to the law on moratorium.
The moratorium question became moot due to the decision in Rutter vs. Esteban invalidating related laws and executive orders.
The remaining issue was whether the debt should be discharged peso for peso in present-day Philippine currency or by its equivalent value according to the Ballantyne scale.

The court referenced the case of Cristobal Rono vs. Jose L. Gomez where a similar dispute was resolved, holding that a promissory note payable at a fixed period must be settled in Philippine currency.
In both cases, the notes contained a fixed maturity date and required payment in the currency prevailing at maturity, emphasizing the importance of the stipulated deadline.

Appellants argued that the promissory note allowed for payment anytime within the four-year period, thereby permitting payment during the Japanese occupation and later discharge by converting the amount using the Ballantyne rate.
The court rejected this interpretation, citing the clear and express language of the instrument which explicitly enjoins payment "four years after date."
The mortgage provision limiting its duration to four years was interpreted as a measure to forestall any extension of the note, rather than to allow early discharge.

Whether the defendant’s debt should be discharged strictly in Philippine currency peso for peso, or
Whether it could be paid by its equivalent in Philippine currency as determined by the Ballantyne scale.

Whether the language "four years after date" in the promissory note permits payment at any time within the four-year period, or
Whether it mandates payment strictly at the maturity date.

Whether the provision in the mortgage regarding its four-year duration has any implication on permitting early payment of the promissory note.

Whether the arguments based on the moratorium law (as advanced by the appellants) are sustainable in light of the precedent set by Rutter vs. Esteban.
