GR L 1538; (November, 1949) (CRITIQUE)

THE AI-ASSISTED CRITIQUE
The Court of Appeals’ factual determination that no duress or intimidation occurred is binding, as the Supreme Court correctly notes that such findings are conclusive absent a showing of grave abuse. The petitioner’s failure to present the notary or witnesses to corroborate his claim of coercion severely undermined his position, reinforcing the appellate court’s reliance on the voluntary execution of the deed. This adherence to factual finality underscores the principle that appellate courts do not reweigh evidence, a cornerstone of hierarchical review that prevents endless litigation over settled factual disputes.

Regarding the validity of Japanese military notes, the Court properly sidestepped the broader constitutional question by focusing on the petitioner’s voluntary acceptance. Even assuming arguendo that the currency proclamations were invalid under international law like the Hague Conventions, the petitioner’s active solicitation of payment and execution of the deed constituted a waiver of any objection to the medium of exchange. This aligns with the doctrine of estoppel, preventing a party from profiting from their own voluntary acts, and avoids unnecessary rulings on the legitimacy of an occupying regime’s decrees—a prudent judicial restraint in politically sensitive post-war contexts.

The decision’s reliance on the companion case (G.R. No. L-18620) creates a consistent jurisprudence but risks oversimplification by treating distinct factual matrices as interchangeable. While efficiency is served, a more nuanced discussion of whether economic coercion in a wartime setting could ever rise to duress might have been warranted, given the exceptional circumstances of 1943 Manila. Nonetheless, the holding that voluntary acceptance validates otherwise questionable consideration remains sound, reinforcing that parties cannot approbate and reprobate—a vital maxim for contractual stability.
