When a Second Spouse Becomes an Accomplice to Bigamy: Santiago v. People

The Supreme Court's 2015 decision in Santiago v. People (G.R. No. 200233) clarifies an important point in Philippine criminal law: a person who knowingly marries someone already bound by a valid prior marriage may be held liable — not as a principal, but as an accomplice to bigamy. The case also warns that parties cannot use their own fraudulent acts to escape criminal responsibility.

The Facts of the Case

Leonila Santiago married Nicanor Santos on 29 July 1997. Four months later, both were charged with bigamy. The prosecution showed that Santos had been married to Estela Galang since 1974, and that the marriage was still subsisting when he wed Santiago.

Santiago pleaded not guilty, arguing she believed Santos was single. She also claimed her marriage to Santos was void because it was celebrated without a marriage license, which should have resulted in her acquittal.

The trial court convicted her as a principal to bigamy, a ruling affirmed by the Court of Appeals.

The Issue Before the Supreme Court

The central questions were: (1) whether Santiago could be held liable for bigamy given her alleged lack of knowledge of Santos's prior marriage; and (2) whether the absence of a marriage license — which would make the second marriage void — should have led to her acquittal.

The Ruling: Liability as an Accomplice, Not a Principal

The Court upheld Santiago's conviction but modified her participation. Under People v. Archilla and People v. Nepomuceno, Jr., a second spouse who knowingly marries someone already wed is liable only as an accomplice, not as a principal. The Court found that Santiago knew of Santos's first marriage based on credible testimony and surrounding circumstances.

Under the Revised Penal Code, the penalty for a principal in bigamy is prision mayor. Since Santiago was an accomplice, she received the penalty next lower in degree — prision correccional. She was sentenced to an indeterminate penalty of six months of arresto mayor as minimum to four years of prision correccional as maximum.

The Court's Rejection of the "Void Marriage" Defense

Santiago argued that her marriage to Santos was void for lack of a marriage license, citing People v. De Lara. The Court acknowledged that a void second marriage normally prevents a bigamy conviction, since the crime requires the second marriage to have all essential requisites for validity.

However, the Court distinguished De Lara. In that case, the accused did not falsify documents. Here, Santiago and Santos misrepresented in their Certificate of Marriage that they had cohabited for at least five years, claiming exemption from the license requirement under Article 34 of the Family Code. In reality, they had known each other for less than four years.

The Court refused to let Santiago benefit from her own fraudulent act. Allowing her to use the flawed marriage she helped create to escape conviction would "make a mockery of the sanctity of marriage." The Court applied the principle that no court will aid a party whose cause of action arises from an illegal act (ex turpi causa).

Practical Takeaways

• Knowledge is key. A second spouse who marries without knowledge of the first marriage is generally not criminally liable. Knowledge of the prior marriage makes the second spouse an accomplice, not a principal.

• Accomplice penalties are lower. An accomplice to bigamy receives the penalty next lower in degree than that imposed on a principal.

• A void marriage can be a defense — but only if honestly obtained. If the second marriage lacks a marriage license without fraud, it may be a valid defense to bigamy. Courts will not entertain the defense when the accused deliberately caused the defect.

• Article 34 requires genuine cohabitation. Exemption from the marriage license requirement demands that the parties actually lived together as husband and wife for at least five years. Merely knowing each other for that period is insufficient.

• Fraud does not pay. A party cannot rely on his or her own illegal or fraudulent act to escape criminal liability.
