G.R. No. L-10396; July 29, 1915
THE UNITED STATES, plaintiff-appellee, vs. TERESA CONCEPCION, defendant-appellant.

FACTS:
The defendant, Teresa Concepcion, was charged with violating the Opium Law for having in her possession and under her control a quantity of opium. On the night of December 2, 1913, policemen searched the house she shared with her husband, Felix Ricablanca. During the search, upon her husband’s order, she retrieved a small can of opium from under a pillow and attempted to discard it, but the policemen seized it. The policemen initially arrested her husband, Felix Ricablanca, and charged him with illegal possession of the same opium. He was later tried and acquitted. More than ten months after the incident, a complaint was filed against Teresa Concepcion. During her trial, the lower court admitted, over her objection, the testimony her husband had given in his own prior criminal case. She was convicted and sentenced to pay a fine.

ISSUE:
1. Whether the evidence was sufficient to prove beyond a reasonable doubt that Teresa Concepcion had illegal possession of opium as contemplated by law.
2. Whether the lower court erred in admitting the testimony of her husband given in a separate case against her objection.

RULING:
The Supreme Court reversed the conviction and ordered the dismissal of the complaint.

1. On the Sufficiency of Evidence for Illegal Possession: The Court held the evidence insufficient to establish guilt beyond a reasonable doubt. The defendant’s momentary act of retrieving the opium at her husband’s command did not constitute the illegal possession prohibited by law. There was no proof she was an opium user, knew the can contained opium, or had the animus possidendi (intent to possess). Her act was that of a faithful wife complying with her husband’s order, not a voluntary assumption of possession with criminal intent.

2. On the Admissibility of the Husband’s Testimony: The Court ruled the lower court committed reversible error in admitting the testimony.
It violated Section 383(3) of the Code of Civil Procedure (Act No. 190), which prohibits a husband from testifying against his wife without her consent, except in civil actions between them or criminal proceedings where one commits a crime against the other. The present case did not fall under any exception.
It also violated the defendant’s right under the Philippine Bill (Act of Congress of July 1, 1902, Sec. 5) “to meet the witnesses face to face.” Using her husband’s testimony from a different case deprived her of the opportunity to cross-examine him in her own trial.
The Court emphasized that this marital disqualification rule, rooted in common law and public policy, protects marital harmony and prevents perjury.

DISPOSITIVE PORTION:
The sentence of conviction was revoked. The complaint was dismissed, and the defendant was ordered discharged from custody, with costs de oficio.
