In its June 22, 2009 Decision,[13] the trial court convicted petitioner of Bigamy and acquitted Baleda. In so ruling, the RTC dismissed Pulido's claim that both his marriages are void. As to the first marriage, the trial court noted that the certifications issued by the Civil Registrar merely proved that the marriage license and marriage application could not be found, not that they never existed, or were never issued. It held that the marriage certificate which reflected on its face the marriage license number of Pulido and Arcon's marriage has a higher probative value than the certifications issued by the Civil Registrar. Moreover, the trial court noted that the testimony of Pulido's witness shows only irregularities in the formal requisites of Pulido's second marriage which did not affect its validity. Thus, the RTC upheld the validity of Pulido's marriage with Arcon. The fallo of the RTC judgment reads: WHEREFORE, judgment is hereby rendered ACQUITTING accused Rowena M. Baleda. In turn, accused LUISITO G. PULIDO is found GUILTY beyond reasonable doubt of the crime of bigamy and he is hereby sentenced to suffer an indeterminate prison term of 2 years, 4 months and 1 day of prision correccional as minimum to 6 years and 1 day of prision mayor as maximum and to suffer the accessory penalty provided for by law and to pay the cost. SO ORDERED.[14] The appellate court further ruled that even assuming that the first marriage was void for lack of a marriage license, one may still be held liable for bigamy if he/she enters into a subsequent marriage without first obtaining a judicial declaration of nullity of the prior marriage. Bigamy was consummated the moment Pulido entered into the second marriage without his marriage with Arcon being first judicially declared null and void. judicial declaration of absolute nullity of either the first and second marriages obtained by the accused is considered a valid defense in bigamy. In the Aragon case already mentioned (supra) we held that if the defendant in a case for bigamy claims that the first marriage is void and the right to decide such validity is vested in another court, the civil action for annulment must first be decided before the action for bigamy can proceed. There is no reason not to apply the same rule when the contention of the accused is that the second marriage is void on the ground that he entered into it because of duress, force and intimidation.[43] (Emphasis supplied.) Upon the enactment of the Family Code on August 3, 1988, the doctrine laid down in Gomez, Consuegra and Wiegel that there is a need for a judicial declaration of nullity of a prior "void" marriage was encapsulated in Article 40, which reads: Article 40. The absolute nullity of a previous marriage may be invoked for purposes of remarriage on the basis solely of a final judgment declaring such previous marriage void. The prevailing rule, therefore, is that even if the marriage is void, a final judgment declaring it void for purposes of remarriage is required. The Commission, in drafting Article 40, considered the Court's ruling in Landicho[49] that parties to a marriage should not be permitted to judge for themselves its nullity; only competent courts have such authority.[50] In Domingo v. Court of Appeals (Domingo),[51] the Court elucidated on the intent behind the provision, thus: "Justice Caguioa explained that his idea is that one cannot determine for himself whether or not his marriage is valid and that a court action is needed. xxx xxxx Prof. Baviera remarked that the original idea in the provision is to require first a judicial declaration of a void marriage and not annullable marriages, with which the other members concurred. Judge Diy added that annullable marriages are presumed valid until a direct action is filed to annul it, which the other members affirmed. Justice Puno remarked that if this is so, then the phrase 'absolute nullity' can stand since it might result in confusion if they change the phrase to 'invalidity' if what they are referring to in the provision is the declaration that the marriage is void. Prof. Bautista commented that they will be doing away with collateral defense as well as collateral attack. Justice Caguioa explained that the idea in the provision is that there should be a final judgment declaring the marriage void and a party should not declare for himself whether or not the marriage is void, which the other members affirmed. Justice Caguioa added that they are, therefore, trying to avoid a collateral, attack on that point. Prof. Bautista stated that there are actions which are brought on the assumption that the marriage is valid. He then asked: Are they depriving one of the right to raise the defense that he has no liability because the basis of the liability is void? Prof. Bautista added that they cannot say that there will be no judgment on the validity or invalidity of the marriage because it will be taken up in the same proceeding. It will not be a unilateral declaration that it is a void marriage. Justice Caguioa saw the point of Prof. Bautista and suggested that they limit the provision to remarriage. He then proposed that Article 39 be reworded as follows: The absolute nullity of a marriage for purposes of remarriage may be invoked only on the basis of final judgment ... Justice Puno suggested that the above be modified as follows: The absolute nullity of a previous marriage may be invoked for purposes of establishing the validity of a subsequent marriage only on the basis of a final judgment declaring such previous marriage void, except as provided in Article 41. Justice Puno later modified the above as follows: For the purpose of establishing the validity of a subsequent marriage, the absolute nullity of a previous marriage may only be invoked on the basis of a final judgment declaring such nullity, except as provided in Article 41. Justice Caguioa commented that the above provision is too broad and will not solve the objection of Prof. Bautista. He proposed that they say: For the purpose of entering into a subsequent marriage, the absolute nullity of a previous marriage may only be invoked on the basis of a final judgment declaring such nullity, except as provided in Article 41. Justice Caguioa explained that the idea in the above provision is that if one enters into a subsequent marriage without obtaining a final judgment declaring the nullity of a previous marriage, said subsequent marriage is void ab initio. xxx After further deliberation, Justice Puno suggested that they go back to the original wording of the provision as follows: The absolute nullity of a previous marriage may be invoked for purposes of remarriage only on the basis of a final judgment declaring such previous marriage void, except as provided in Article 41." [52] (Emphasis supplied.) To repeat, Pulido's first marriage with Arcon was contracted in 1983 or before the effectivity of the Family Code while his second marriage with Baleda was celebrated in 1995, during the effectivity of the said law. Pulido assails the retroactive application of Article 40 of the Family Code on his case which requires him to obtain a judicial declaration of absolute nullity before he can contract another marriage. When the prior marriage was contracted prior to the effectivity of the Family Code while the subsequent marriage was contracted during the effectivity of the said law, we recognize the retroactive application of Article 40 of the Family Code but only insofar as it does not prejudice or impair vested or acquired rights. In Atienza v. Brillantes, Jr.,[53] and reiterated in Jarillo[54] and in Montañez v. Cipriano (Montañez),[55] we declared thus: As far back as 1995, in Atienza v. Brillantes, Jr., the Court already made the declaration that Article 40, which is a rule of procedure, should be applied retroactively because Article 256 of the Family Code itself provides that said "Code shall have retroactive effect insofar as it does not prejudice or impair vested or acquired rights." The Court went on to explain, thus: Marbella-Bobis v. Bobis[63] (Marbella-Bobis) held that without a judicial declaration of nullity, the first marriage is presumed to be subsisting and for all legal intents and purposes, the parties are considered as married at the time the second marriage was celebrated.[64] Hence, he who contracts a second marriage before the judicial declaration of nullity of the first marriage assumes the risk of being prosecuted for bigamy, [65] Thus, the Court declared that: In the light of Article 40 of the Family Code, respondent, without first having obtained the judicial declaration of nullity of the first marriage, cannot be said to have validly entered into the second marriage. Per current jurisprudence, a marriage though void still needs a judicial declaration of such fact before any party can marry, again; otherwise the second marriage will also be void. The reason is that, without a judicial declaration of its nullity, the first marriage is presumed to be subsisting. In the case at bar, respondent was for all legal intents and purposes regarded as a married man at the time he contracted his second marriage with petitioner. Against this legal backdrop, any decision in the civil action for nullity would not erase the fact that respondeat entered into a second marriage during the subsistence of a first marriage. Thus, a decision in the civil case is not essential to the determination of the, criminal charge. It is, therefore, not a prejudicial question. As stated above, respondent cannot be permitted to use his own malfeasance to defeat the criminal action against him.[66] (Emphasis supplied.) A thorough review of the foregoing rulings shows that the judicial declarations of absolute nullity of the first and second marriages obtained subsequent to the celebration of the second marriage are not valid defenses in the criminal prosecution for bigamy. The only valid defense recognized by the Court in the above-mentioned cases is a judicial declaration of absolute nullity of the first marriage obtained by the accused prior to the celebration of the second marriage. However, if the first marriage is merely voidable, the accused cannot interpose an annulment decree as a defense in the criminal prosecution for bigamy since the voidable first marriage is considered valid and subsisting when the second marriage was contracted. The crime of bigamy, therefore, is consummated when the second marriage was celebrated during the subsistence of the voidable first marriage. The same rule applies if the second marriage is merely considered as voidable. To our mind, 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 accused may present testimonial or documentary evidence such as the judicial declaration of absolute nullity of the first and/or subsequent void ab initio marriages in the criminal prosecution for bigamy. The said view is more in accord with the retroactive effects of a void ab initio marriage, the purpose of and legislative intent behind Article 40 of the Family Code, and the rule on statutory construction of penal laws. Therefore, the absence of a "prior valid marriage" and the subsequent judicial declaration of absolute nullity of his first marriage, Pulido is hereby acquitted from the crime of Bigamy charged against him. New Doctrine on Bigamy: Pulido v. People Summary In the leading case of Pulido v. People, G.R. No. 220149, 27 July 2021, Hernando, J., the SC en banc exonerated the accused from criminal liability for bigamy when during the pendency of the bigamy case, a judicial declaration of nullity of the first marriage was entered. Previous decisions had held that a person who contracts a second marriage without a prior court declaration of nullity of his first marriage was liable for bigamy even if the first marriage was subsequently declared void by a court. The SC held in Pulido that the requirement of a prior judicial declaration of nullity under Article 40 of the Family Code, which is for purposes only of remarriage, should not have been extended to criminal cases. Case law prior to Pulido The crime of bigamy is committed by any person who shall contract a second or subsequent marriage while validly married to another. (See Article 349, Revised Penal Code). Consider this hypothetical: Horace contracted marriage with Annika. Horace then filed a petition for declaration of nullity of his marriage to Annika on the ground of absence of a marriage license. While this petition was pending, Horace contracted a second marriage with Blondie. When Annika learned of this, she filed a criminal complaint with the prosecutor for bigamy against Horace. The information for bigamy against Horace was subsequently filed in court. (a) Horace filed a motion for suspension of the criminal case on the ground that the marriage nullification case presented a prejudicial question. Should the motion be granted? (b) Assume that the motion was not granted. During the pendency of the criminal case, judgment was entered declaring the marriage between Horace and Annika as void because of the absence of a marriage license. Will the judgment exonerate Horace from criminal liability? Prior to Pulido, the answer to (a) was in the negative. The petition for declaration of nullity of marriage will not pose a prejudicial question since, as will be discussed in the answer to (b), Horace can still be convicted of bigamy even if his prior marriage to Annika was later nullified. The answer to (b) was also in the negative. In a line of cases, the Supreme Court has held that a spouse cannot take the law into his own hands and contract marriage without a previous judicial declaration of nullity of the prior marriage. “Persons intending to contract a second marriage must first secure a judicial declaration of nullity of their first marriage. If they proceed with the second marriage without the judicial declaration, they are guilty of bigamy regardless of evidence of the nullity of the first marriage.” (See Vitangcol v. People, 780 SCRA 598 [2016]). This holding was based on Article 40 of the Family Code which provides that “[t]he absolute nullity of a previous marriage may be invoked for purposes of remarriage on the basis solely of a final judgment declaring such previous marriage void.” The Pulido case In Pulido, the petitioner contracted marriage with a woman whom we shall refer to as W1. Subsequently, petitioner contracted marriage with another woman, W2. Stung by this betrayal, W1 filed a complaint for bigamy against the petitioner. The petitioner’s defense was that his marriage with W1 was void because of the absence of a marriage license. In accordance with the then case law, the petitioner was however convicted by the RTC of Las Piñas City since there was no prior judicial declaration of his marriage with W1 at the time he married W2. The Court of Appeals affirmed the petitioner’s conviction and the case was elevated to the Supreme Court. While the case was pending in the Supreme Court, a judgment was entered by the RTC of Imus, Cavite, declaring the marriage between the petitioner and W1 as void due to the absence of a marriage license. With this development, the Supreme Court held that the petitioner should be exonerated from criminal liability. The High Court stated that for bigamy to arise, there must have been a prior valid marriage. The fact that the judicial declaration of nullity was obtained after the accused had contracted the second marriage will still not give rise to bigamy because a void marriage is inexistent from the very beginning. With respect to Article 40 of the Family Code, the Court held that its application to a bigamy charge was not warranted. The Court held that by the express terms of Article 40, the prior judicial declaration of nullity of the marriage is a requirement only for purposes of remarriage and that Article 40 should not have been construed as imposing a requirement for the accused to raise the defense of nullity of the first marriage. Thus, in the light of Pulido, the answer now to (b) of the hypothetical is that the judgment of nullification will exonerate Horace from criminal liability for bigamy. Effect of Pulido on prior rulings re prejudicial question The doctrine laid down in Pulido will necessarily call for a revisit of previous doctrines which held that a pending marriage nullification case will not pose a prejudicial question in a bigamy case. In light of Pulido, the answer to (a) of the hypothetical is that the motion for suspension on the ground of prejudicial question should be granted. The resolution of the issue of whether the prior marriage between Horace and W1 is valid is determinative of whether the criminal case for bigamy will proceed. It should be noted that by virtue of the 1 December 2000 amendments to the Rules of Criminal Procedure, the civil case in order to pose a prejudicial question must have been filed prior to the institution of the criminal case. Hence, if the civil case for marriage nullification was filed after the criminal case had been instituted, there will be no suspension of the criminal case on the ground of prejudicial question. In such a case, the remedy of the accused is to prove the nullity of his prior marriage in the criminal case. Pulido held that a prior judicial declaration is not the sole means of proving the nullity of the prior marriage. The accused may collaterally attack the validity of the first marriage by introducing evidence, for example, that no marriage license was obtained therein. The Court held that a certification from the LCR that no record of a marriage license was found in its record would cast reasonable doubt on the accused’s guilt. Retroactive effect of Pulido What about an accused who had been convicted of bigamy notwithstanding a judicial declaration of nullity of his marriage? May he invoke the Pulido doctrine? It is submitted that the accused may do so. It is axiomatic that a law should be given retroactive effect if favorable to the accused. (Article 22, Revised Penal Code). Judicial decisions favorable to an accused should be given retroactive effect since such decisions form part of the law in accordance with Article 8 of the Civil Code and so as not to infringe upon the constitutional right of the accused to equal protection of the law. (Gumabon v. Director of Prisons, 37 SCRA 420 [1971]). In such a case, the accused may file a petition for habeas corpus to obtain his release from prison. The crime of bigamy does not necessary entail the joint liability of two persons who marry each other while the previous marriage of one of them is valid and subsisting. As explained in Nepomuceno: 18 In the crime of bigamy, both the first and second spouses may be the offended parties depending on the circumstances, as when the second spouse married the accused without being aware of his previous marriage. Only if the second spouse had knowledge of the previous undissolved marriage of the accused could she be included in the information as a co-accused. (Emphasis supplied) Therefore, the lower courts correctly ascertained petitioner's knowledge of Santos's marriage to Galang. Both courts consistently found that she knew of the first marriage as shown by the totality of the following circumstances: 19 (1) when Santos was courting and visiting petitioner in the house of her in-laws, they openly showed their disapproval of him; (2) it was incredible for a learned person like petitioner to not know of his true civil status; and (3) Galang, who was the more credible witness compared with petitioner who had various inconsistent testimonies, straightforwardly testified that she had already told petitioner on two occasions that the former was the legal wife of Santos. After a careful review of the records, we see no reason to reverse or modify the factual findings of the R TC, less so in the present case in which its findings were affirmed by the CA. Indeed, the trial court's assessment of the credibility of witnesses deserves great respect, since it had the important opportunity to observe firsthand the expression and demeanor of the witnesses during the trial. 20 Given that petitioner knew of the first marriage, this Court concurs with the ruling that she was validly charged with bigamy. However, we disagree with the lower courts' imposition of the principal penalty on her. To recall, the RTC, which the CA affirmed, meted out to her the penalty within the range of prision correctional as minimum to prision mayor as maximum. Her punishment as a principal to the crime is wrong. Archilla 21 holds that the second spouse, if indicted in the crime of bigamy, is liable only as an accomplice. In referring to Viada, Justice Luis B. Reyes, an eminent authority in criminal law, writes that "a person, whether man or woman, who knowingly consents or agrees to be married to another already bound in lawful wedlock is guilty as an accomplice in the crime of bigamy." 22 Therefore, her conviction should only be that for an accomplice to the crime. Under Article 349 of the Revised Penal Code, as amended, the penalty for a principal in the crime of bigamy is prision mayor, which has a duration of six years and one day to twelve years. Since the criminal participation of petitioner is that of an accomplice, the sentence imposable on her is the penalty next lower in degree, 23 prision correctional, which has a duration of six months and one day to six years. There being neither aggravating nor mitigating circumstance, this penalty shall be imposed in its medium period consisting of two years, four months and one day to four years and two months of imprisonment. Applying the Indeterminate Sentence Law, 24 petitioner shall be entitled to a minimum term, to be taken from the penalty next lower in degree, arresto mayor, which has a duration of one month and one day to six months imprisonment. The criminal liability of petitioner resulting from her marriage to Santos Jurisprudence clearly requires that for the accused to be convicted of bigamy, the second or subsequent marriage must have all the essential requisites for validity. 25 If the accused wants to raise the nullity of the marriage, he or she can do it as a matter of defense during the presentation of evidence in the trial proper of the criminal case. 26 In this case, petitioner has consistently27 questioned below the validity of her marriage to Santos on the ground that marriages celebrated without the essential requisite of a marriage license are void ab initio. 28 Unfortunately, the lower courts merely brushed aside the issue. The RTC stated that it could not pass judgment on the validity of the marriage. The CA held that the attempt of petitioner to attack her union with Santos was in vain. 1âwphi1 On the basis that the lower courts have manifestly overlooked certain issues and facts, 29 and given that an appeal in a criminal case throws the whole case open for review, 30 this Court now resolves to correct the error of the courts a quo. After a perusal of the records, it is clear that the marriage between petitioner and Santos took place without a marriage license. The absence of this requirement is purportedly explained in their Certificate of Marriage, which reveals that their union was celebrated under Article 34 of the Family Code. The provision reads as follows: No license shall be necessary for the marriage of a man and a woman who have lived together as husband and wife for at least five years and without any legal impediment to marry each other. The contracting parties shall state the foregoing facts in an affidavit before any person authorized by law to administer oaths. The solemnizing officer shall also state under oath that he ascertained the qualifications of the contracting parties are found no legal impediment to the marriage.31 Here, respondent did not dispute that petitioner knew Santos in more or less in February 1996 32 and that after six months of courtship,33 she married him on 29 July 1997. Without any objection from the prosecution, petitioner testified that Santos had frequently visited her in Castellano, Nueva Ecija, prior to their marriage. However, he never cohabited with her, as she was residing in the house of her in-laws,34 and her children from her previous marriage disliked him.35 On cross examination, respondent did not question the claim of petitioner that sometime in 1993, she first met Santos as an agent who sold her piglets.36 All told, the evidence on record shows that petitioner and Santos had only known each other for only less than four years. Thus, it follows that the two of them could not have cohabited for at least five years prior to their marriage. Santiago and Santos, however, reflected the exact opposite of this demonstrable fact. Although the records do not show that they submitted an affidavit of cohabitation as required by Article 34 of the Family Code, it appears that the two of them lied before the solemnizing officer and misrepresented that they had actually cohabited for at least five years before they married each other. Unfortunately, subsequent to this lie was the issuance of the Certificate of Marriage, 37 in which the solemnizing officer stated under oath that no marriage license was necessary, because the marriage was solemnized under Article 34 of the Family Code. The legal effects in a criminal case of a deliberate act to put a flaw in the marriage The Certificate of Marriage, signed by Santos and Santiago, contained the misrepresentation perpetrated by them that they were eligible to contract marriage without a license. We thus face an anomalous situation wherein petitioner seeks to be acquitted of bigamy based on her illegal actions of (1) marrying Santos without a marriage license despite knowing that they had not satisfied the cohabitation requirement under the law; and (2) falsely making claims in no less than her marriage contract. We chastise this deceptive scheme that hides what is basically a bigamous and illicit marriage in an effort to escape criminal prosecution. Our penal laws on marriage, such as bigamy, punish an individual's deliberate disregard of the permanent and sacrosanct character of this special bond between spouses.38 In Tenebro v. Court of Appeals,39 we had the occasion to emphasize that the State's penal laws on bigamy should not be rendered nugatory by allowing individuals "to deliberately ensure that each marital contract be flawed in some manner, and to thus escape the consequences of contracting multiple marriages, while beguiling throngs of hapless women with the promise of futurity and commitment." Thus, in the case at bar, we cannot countenance petitioner's illegal acts of feigning a marriage and, in the same breath, adjudge her innocent of the crime. For us, to do so would only make a mockery of the sanctity of marriage. 40 Furthermore, it is a basic concept of justice that no court will "lend its aid to x x x one who has consciously and voluntarily become a party to an illegal act upon which the cause of action is founded." 41 If the cause of action appears to arise ex turpi causa or that which involves a transgression of positive law, parties shall be left unassisted by the courts. 42 As a result, litigants shall be denied relief on the ground that their conduct has been inequitable, unfair and dishonest or fraudulent, or deceitful as to the controversy in issue. 43 Here, the cause of action of petitioner, meaning her affirmative defense in this criminal case of bigamy, is that her marriage with Santos was void for having been secured without a marriage license. But as elucidated earlier, they themselves perpetrated a false Certificate of Marriage by misrepresenting that they were exempted from the license requirement based on their fabricated claim that they had already cohabited as husband and wife for at least five years prior their marriage. In violation of our law against illegal marriages,44 petitioner married Santos while knowing full well that they had not yet complied with the five-year cohabitation requirement under Article 34 of the Family Code. Consequently, it will be the height of absurdity for this Court to allow petitioner to use her illegal act to escape criminal conviction. The applicability of People v. De Lara Petitioner cites De Lara as the relevant jurisprudence involving an acquittal for bigamy on the ground that the second marriage lacked the requisite marriage license. In that case, the Court found that when Domingo de Lara married his second wife, Josefa Rosales, on 18 August 1951, the local Civil Registrar had yet to issue their marriage license on 19 August 1951. Thus, since the marriage was celebrated one day before the issuance of the marriage license, the Court acquitted him of bigamy. Noticeably, Domingo de Lara did not cause the falsification of public documents in order to contract a second marriage. In contrast, petitioner and Santos fraudulently secured a Certificate of Marriage, and petitioner later used this blatantly illicit act as basis for seeking her exculpation. Therefore, unlike our treatment of the accused in De Lara, this Court cannot regard petitioner herein as innocent of the crime. No less than the present Constitution provides that "marriage, as an inviolable social institution, is the foundation of the family and shall be protected by the State." 45 It must be safeguarded from the whims and caprices of the contracting parties. 46 in keeping therefore with this fundamental policy, this Court affirms the conviction of petitioner for bigamy WHEREFORE, the Petition for Review on Certiorari filed by petitioner Leonila G. Santiago is DENIED. The Decision and Resolution of the Court of Appeals in CA-G.R. CR No. 33566 is AFFIRMED with MODIFICATION. As modified, petitioner Leonila G. Santiago is hereby found guilty beyond reasonable doubt of the crime of bigamy as an accomplice. She is sentenced to suffer the indeterminate penalty of six months of arresto mayor as minimum to four years of prision correctional as maximum plus accessory penalties provided by law.
