Bigamy Doctrine, 1954–2026 [From People v. Mendoza (1954) to Pulido v. People (2021) and Tungol (2026)]

 

Article 349, Revised Penal Code  ·  Philippine Supreme Court

Bigamy: seventy-two years of a rule that kept changing its mind

One question has governed almost every bigamy prosecution in Philippine history: must an accused first obtain a judicial declaration that the earlier marriage was void, before that nullity can be used as a defense? The Court has answered it both ways — repeatedly. In 2021 it reversed itself again, and this time abandoned twenty-eight years of contrary doctrine.

Pulido v. People

A void ab initio marriage may be raised as a defense in a bigamy prosecution without any prior judicial declaration of its nullity. Article 40 of the Family Code did not amend Article 349 of the Revised Penal Code; the judicial declaration it requires is for purposes of remarriage, not an element of the crime and not a precondition to the defense. The accused may prove nullity by testimonial or documentary evidence, including a declaration obtained after the fact.

G.R. No. 220149 · July 27, 2021 · EN BANC · Hernando, J.
Concurring opinions: Perlas-Bernabe, Caguioa, Lazaro-Javier, JJ. · Petitioner ACQUITTED.

A void ab initio first marriage is a defense — no prior declaration required.

A void ab initio subsequent marriage may likewise be raised.

The rule applies to marriages celebrated under both the Civil Code and the Family Code.

A second marriage void only because it is bigamous is not a defense.

A merely voidable first marriage is not: an annulment decree cannot be interposed, because the marriage was valid and subsisting when the second was contracted.

1954 — 1957 The permissive rule Civil Code. A void marriage needs no decree to be treated as void.
1954

People v. Mendoza

95 Phil. 845

No judicial decree is necessary to establish the invalidity of a void prior marriage as a defense in bigamy — as distinguished from voidable marriages. The accused, whose second marriage was void for bigamy and whose first wife had died, did not commit bigamy by contracting a third.

Defense allowed
1957

People v. Aragon

100 Phil. 1033

Reaffirmed Mendoza on materially identical facts. For three decades this was understood as the settled rule.

Defense allowed
1970 — 1986 The oscillation Four reversals in sixteen years. The Court could not hold a position.
1970

Gomez v. Lipana

144 Phil. 514

Deviated from Mendoza and Aragon: a judicial declaration of nullity is necessary even though the marriage is presumed void for having been contracted during a prior subsisting marriage.

Declaration required
1971

Vda. de Consuegra v. GSIS

147 Phil. 269

Followed Gomez.

Declaration required
1977 · 1983

Odayat v. Amante · Tolentino v. Paras

168 Phil. 1  ·  207 Phil. 458

The Court reverted to Mendoza and Aragon.

Defense allowed
1986

Wiegel v. Sempio-Diy

227 Phil. 457

Reversed course again: a judicial declaration of nullity of a void marriage is required before one may enter another. This reasoning would later be codified in Article 40 of the Family Code.

Declaration required
1986

Yap v. Court of Appeals

229 Phil. 251

In the same year as Wiegel, the Court held otherwise once more.

Defense allowed
1997

Apiag v. Cantero · Ty v. Court of Appeals

335 Phil. 511

Clarified the confusion by drawing a line at the statute: the requirement of a judicial decree does not apply to marriages celebrated before the Family Code, which remain governed by Mendoza, Aragon and Odayat.

Defense allowed — pre-Family Code
1993 — 2016 Article 40 hardens Twenty-three years of consistent doctrine against the accused.
1993

Domingo v. Court of Appeals

297 Phil. 642

A declaration of absolute nullity is required, whether pleaded as a cause of action or as a defense. Parties may not judge for themselves whether their marriage is void; only a competent court may say so.

Declaration required
2000

Mercado v. Tan

391 Phil. 809

Expressly abandoned Mendoza and Aragon as superseded by Article 40. A declaration of nullity obtained after the second marriage is immaterial — the crime was already consummated. To hold otherwise would let an accused file a nullity petition and invoke it to stall the prosecution.

Declaration required
2000

Marbella-Bobis v. Bobis

384 Phil. 661

A pending petition to nullify the first marriage is not a prejudicial question that suspends the bigamy case.

Declaration required
2004

Tenebro v. Court of Appeals

467 Phil. 723

Extended the rule to the second marriage: its later declaration of nullity for psychological incapacity is "of absolutely no moment insofar as the State's penal laws are concerned." Article 349 punishes the mere act of contracting a second marriage during a subsisting valid one.

Declaration required
2004

Morigo v. People

466 Phil. 1013

The outlier. The parties merely signed a marriage contract with no ceremony and no solemnizing officer — so there was no first marriage at all, and the first element of bigamy was missing. Acquittal. Pulido would later note that Morigo and Mercado were "at variance" on the effects of a void marriage.

Acquitted — no marriage existed
2005 — 2016

The consolidation

Manuel · Jarillo · Nollora · Montañez · Lasanas · Vitangcol

Manuel v. People (512 Phil. 818), Jarillo v. People (617 Phil. 45), Nollora, Jr. v. People (672 Phil. 771), Montañez v. Cipriano (697 Phil. 586), Lasanas v. People (736 Phil. 735) and Vitangcol v. People (778 Phil. 326) each reapplied the rule. Jarillo held Article 40 applies even to marriages governed by the Civil Code; the line held that even a first marriage void for want of a licence left the accused liable absent a prior decree.

Declaration required
2021 — present The reversal En Banc. The Court abandons its own twenty-eight-year line.

Pulido v. People

G.R. No. 220149 · Hernando, J. · ACQUITTED

"It is time to abandon the earlier precedents and adopt a more liberal view that a void ab initio marriage can be used as a defense in bigamy even without a separate judicial declaration of absolute nullity." The parties need not obtain a declaration to raise nullity of either the first or the subsequent marriage; the rule now applies to marriages under both Codes; and Article 40 did not deny the accused the right to collaterally attack a void marriage in a criminal prosecution. The Court rested this on the retroactive effects of a void marriage, the legislative intent behind Article 40, and the rule that penal laws are construed strictly against the State.

Defense allowed
February 26, 2026

Lapira-y-Tungol v. Fariscal

G.R. No. 233512 · Third Division · Caguioa, J. · ACQUITTED

The first squarely on-point application. The accused raised the nullity of her first marriage for want of a licence without any prior declaration, invoking Pulido, and rebutted the presumption of validity with a civil registrar's certification that no licence was ever issued. One element of bigamy therefore failed. The case supplies the evidentiary standard Pulido left open for this ground of nullity.

Defense allowed
The analysis

What actually changed

QuestionMercado line (2000–2016)Pulido (2021– )
Void first marriage, no prior decree Not a defense. Crime already consummated. A defense. No decree needed.
Decree obtained after the second marriage Immaterial. Admissible as evidence of nullity.
Void second marriage Immaterial (Tenebro). May be raised — unless void only for being bigamous.
Voidable first marriage Not a defense. Still not a defense. Unchanged.
Marriages under the Civil Code Article 40 applied retroactively (Jarillo). Same rule for both Codes — now the permissive one.
Function of Article 40 A precondition to the defense. A requirement for remarriage only. It did not amend Article 349.
Rule of construction Protect the institution of marriage; deter evasion. Penal laws construed strictly against the State.
Unsettled

What Pulido did not decide

Retroactive benefit to final convictions

Pulido is favourable to the accused, and penal rules favourable to the accused ordinarily apply retroactively. Whether that reaches convictions already final — and by what remedy — is not resolved in any decision I could verify.

Prejudicial question

Pulido records that Merced, Zapanta and De la Cruz — which had treated a nullity action as a prejudicial question — were abandoned, and that under the rule it was reviewing, nullity of the second marriage was neither a defense nor a prejudicial question. Having restored the defense, the Court did not squarely say whether the prejudicial-question doctrine returns with it.

Morigo's continuing role

Morigo turned on the absence of any ceremony, not on the absence of a decree. Under Pulido that distinction may no longer carry weight, since nullity on any ground is now available as a defense — but Morigo has not been expressly superseded.
