G.R. No. L-35978 & L-36069 December 26, 1974
EMMA MONDRAGON, petitioner, vs. THE COURT OF APPEALS and THE PEOPLE OF THE PHILIPPINES, respondents.

FACTS

Petitioner Emma Mondragon, married to Frank Fernando, was convicted alongside Luis Abdon Jr. of two counts of adultery by the City Court of Quezon City. The convictions were affirmed with penalty modifications by the Court of Appeals. The prosecution’s case hinged on testimonies from three witnesses: Aristeo Mondragon (petitioner’s brother), Caridad Abdon (the wife of Luis Abdon Jr.), and Maria Catalan (a neighbor). Aristeo and Caridad testified to witnessing the accused in compromising situations indicative of an illicit relationship. However, during cross-examination, both Aristeo and Caridad recanted their direct testimonies. They claimed their inculpatory statements were not true and were the result of instructions from the private prosecutor.
The trial court and the Court of Appeals discounted these recantations. The trial judge observed Aristeo’s father exerting a sharp look during the recantation, implying coercion to retract. The appellate court found the original direct testimonies credible, noting no proven ulterior motive for the witnesses to falsely testify initially. It held that the trial court did not rely on evidence from a separate administrative case but merely referenced it to establish the accused’s awareness of their respective marital statuses.

ISSUE

Whether the Court of Appeals erred in affirming petitioner’s conviction based on the testimonies of witnesses who subsequently recanted their direct examinations.

RULING

The Supreme Court reversed the decision and acquitted petitioner Emma Mondragon due to insufficiency of evidence. The legal logic centered on the proper judicial treatment of a witness’s self-contradiction under oath. The Court distinguished the situation from mere inconsistencies between different witnesses or prior inconsistent statements given on separate occasions. Here, within the same trial, the two key witnesses repudiated their entire direct testimonies, attributing the falsehoods to the private prosecutor’s instructions.
Applying established doctrines from U.S. vs. Pala, the Court held that when a witness makes two sworn statements in the same case that are in “gravest contradiction,” and the contradiction reveals willful falsehood induced by counsel, neither statement can be accepted as proof. The witness impeaches their own testimony, compelling the court to exclude it from consideration. Consequently, the testimonies of Aristeo Mondragon and Caridad Abdon were rendered legally worthless and had to be disregarded entirely.
With these two testimonies invalidated, the only remaining evidence was from Maria Catalan. Given the demonstrated manipulation of witness testimony by the prosecution, her testimony became suspect and insufficient to sustain a conviction beyond reasonable doubt. The Court emphasized that in such circumstances, the evidence cannot be evaluated to choose which contradictory statement is true; both must be discarded as a matter of law, leading to an acquittal.
