G.R. No. 25338 | People of the Philippine Islands vs. Simeon Solanga | September 9, 1926 | Ostrand, J.

FACTS:
The defendant-appellant, Simeon Solanga, was convicted of homicide for killing David Gupalao. The prosecution’s primary evidence was Solanga’s extrajudicial confession before the justice of the peace, where he admitted that upon returning home, he found his mistress, Catalina Habitan, having sexual intercourse with Gupalao. A struggle ensued, Gupalao struck him and tried to take his bolo, and in a state of excitement and rage, Solanga used the bolo to inflict multiple wounds on Gupalao, who later died.

At trial, Solanga presented a different version, claiming he found Gupalao attempting to rape Catalina (whom he now called his lawful wife), acted in defense, and that Gupalao accidentally impaled himself on the bolo during the struggle. Catalina initially corroborated this defense at trial but was impeached by her prior sworn statement given immediately after the incident, which largely supported Solanga’s original confession and described an unprovoked attack.

ISSUE

Whether the mitigating circumstances of passion and obfuscation (Article 9, No. 7, Revised Penal Code) and lack of education and instruction (Article 11, RPC) should be appreciated in favor of the appellant to reduce his penalty.

RULING

Yes. The Supreme Court modified the trial court’s judgment.

The Court found that the evidence clearly showed Solanga and Catalina were not legally married, thus Article 423 of the RPC (which provides a lesser penalty for a spouse who kills or injures a partner caught in the act of adultery) did not strictly apply. However, the Court held that discovering his mistress and the deceased in a compromising situation, coupled with the invasion of his home, produced a powerful impulse amounting to passion and obfuscation, a mitigating circumstance under Article 9(7).

Furthermore, the Court considered Solanga’s lack of instruction and education as an extenuating circumstance under Article 11. It noted that in backward communities, such informal unions carried moral sanction akin to legal marriage, making his level of education directly pertinent to his culpability.

With two mitigating circumstances and no aggravating circumstances, the penalty was reduced by one degree under Article 81(5) of the RPC. The Court modified the penalty from *reclusion temporal* to six years and one day of *prision mayor*, with accessory penalties. The indemnity and costs were affirmed.

DISSENTING OPINION (Villamor, J.):
Justice Villamor believed the evidence justified applying the first paragraph of Article 423 of the RPC, implying an even lesser penalty than the majority applied.
