Juliano-Llave vs. Republic of the Philippines

A marriage solemnized under the Civil Code before the effectivity of the Code of Muslim Personal Laws (P.D. 1083) is governed by the Civil Code and cannot be dissolved by a divorce obtained under the later Muslim Code, because the Muslim Code operates prospectively and preserves rights already vested under prior law; a subsequent marriage contracted during the subsistence of such prior marriage is bigamous and void ab initio.

On May 31, 1958, Senator Mamintal A.J. Tamano and respondent Haja Putri Zorayda A. Tamano were married in both civil and Muslim ceremonies. At that time, absolute divorce was not recognized under the governing Civil Code. Nearly 35 years later, about eleven months before his death, Senator Tamano married petitioner Estrellita Juliano-Llave twice in 1993—first under Islamic law and tradition, and subsequently in a civil ceremony—indicating his civil status as “divorced.” After the senator’s death, a dispute arose between the two women and the senator’s children over the validity of the second marriage.

• The First Marriage: Senator Mamintal A.J. Tamano and respondent Haja Putri Zorayda A. Tamano were married on May 31, 1958 in ceremonies that were both civil and Muslim in character. At the time, the governing law was the Civil Code of 1950, which did not permit absolute divorce. The marriage was never annulled or legally dissolved, and no divorce was obtained under Republic Act No. 394 while it was in effect. The spouses never registered a mutual desire to be covered by the Code of Muslim Personal Laws after its enactment in 1977.

• The Subsequent Marriages of Senator Tamano: In 1993, roughly eleven months before his death, Senator Tamano married petitioner Estrellita Juliano-Llave on two occasions—first according to Islamic laws and tradition on May 27, 1993 in Cotabato City, and then in a civil ceremony before an RTC Judge on June 2, 1993 in Malabang, Lanao del Sur. In the marriage contracts, Tamano’s civil status was stated as “divorced.” Following the senator’s death, petitioner publicly presented herself as his widow.

• The Complaint for Declaration of Nullity: On November 23, 1994, respondents Zorayda and her son Adib, acting for themselves and on behalf of the senator’s other legitimate children with Zorayda, filed a complaint in the RTC of Quezon City seeking the declaration of nullity of the second marriage. The complaint alleged that the first marriage remained subsisting, that Tamano could not have validly obtained a divorce under the Civil Code, and that P.D. 1083 did not apply because the spouses never registered their consent to be governed by it. The subsequent marriage was claimed to be void ab initio for bigamy under Article 35(4) of the Family Code.

• Petitioner’s Response and Trial Proceedings: Petitioner obtained extensions to file an answer but instead filed a Motion to Dismiss on February 20, 1995, asserting that shari’a courts had exclusive jurisdiction over the validity of Muslim marriages. The trial court denied the motion. While her certiorari challenge (eventually G.R. No. 126603) was pending, petitioner was never declared in default and actively participated in the proceedings. However, she persistently refused to file an answer and, when it was her turn to adduce evidence, sought repeated postponements, insisting that the trial court should await the final outcome of her jurisdictional challenge. The RTC ultimately deemed her to have waived her right to present evidence and rendered judgment solely on the evidence offered by respondents.

• Prematurity and Denial of Due Process: Petitioner argued that the RTC judgment was prematurely rendered because she had not yet filed an answer and the trial court should have awaited the Supreme Court’s final resolution of G.R. No. 126603. She invoked Judge Macias v. Macias, asserting that the filing of a motion to dismiss suspends the period to file an answer and obliges the trial court to hold proceedings in abeyance until the jurisdictional challenge is resolved with finality. She maintained that her participation in the trial was without prejudice to her certiorari petition and that the RTC violated that assurance.

• Lack of Collusion Report: Petitioner contended that the trial court failed to require the public prosecutor to investigate and report on the existence of collusion, a mandatory requirement under Article 48 of the Family Code and Rule 9, Section 3(e) of the Rules of Court. She asserted that this omission invalidated the proceedings.

• Validity of the Marriage under Muslim Law: Petitioner maintained that Senator Tamano’s prior marriage was governed by the Code of Muslim Personal Laws because both spouses were Muslims whose union was solemnized under Muslim rites. She argued that P.D. 1083 automatically applied without the need for registration of mutual consent, that Tamano validly divorced Zorayda under that Code, and that he was therefore capacitated to marry her.

• Lack of Standing: Petitioner claimed that under Section 2(a) of A.M. No. 02-11-10-SC, only the husband or the wife may file a petition for declaration of absolute nullity of marriage. Hence, respondents Zorayda and Adib, who are not parties to the second marriage, had no legal standing to bring the suit.

• No Denial of Due Process: The Solicitor General argued that petitioner was never deprived of her right to be heard; she was given ample opportunity to file an answer and present evidence but employed dilatory tactics. The pendency of a certiorari petition does not stay the main proceedings absent a restraining order or injunction, and no such order was in effect.

• Substantial Compliance with Collusion Requirement: The Solicitor General maintained that a formal investigation report was unnecessary because petitioner’s vigorous opposition to the suit conclusively negated the possibility of collusion. Even assuming a deficiency, the lack of the fiscal’s participation is not fatal to the validity of the proceedings, as held in Tuason v. Court of Appeals.

• Bigamous Nature of the Marriage: The Solicitor General defended the lower courts’ conclusion that the Civil Code governed the 1958 marriage. P.D. 1083 cannot be applied retroactively to impair vested rights; the prior marriage was never dissolved and remained subsisting, rendering the subsequent union void ab initio.

• Proper Parties to Sue: The Solicitor General countered that a void marriage may be attacked directly or collaterally by any interested party. Respondents, as the prejudiced prior spouse and compulsory heir, had a real interest in the suit. The restrictions under A.M. No. 02-11-10-SC do not apply retroactively to a case filed in 1994.

• Due Process and Prematurity of Judgment: Whether the trial court’s judgment was rendered prematurely and in violation of petitioner’s right to due process, considering that (a) her certiorari petition questioning the denial of the motion to dismiss was still pending final resolution, (b) she had not filed an answer, and (c) the public prosecutor allegedly failed to conduct an investigation and submit a report on collusion.

• Validity of the Second Marriage (Bigamy): Whether the marriage between petitioner and Senator Tamano was bigamous and therefore void ab initio in light of the effect of P.D. 1083 on the prior marriage celebrated under civil and Muslim rites in 1958.

• Standing to File the Nullity Suit: Whether respondents Zorayda and Adib had the legal standing to seek the declaration of nullity of petitioner’s marriage under A.M. No. 02-11-10-SC and general principles governing real parties-in-interest.

• Due Process and Prematurity of Judgment: No denial of due process occurred. Petitioner was never declared in default and actively participated in the proceedings. Judge Macias v. Macias was distinguished: it merely requires the trial court to suspend proceedings until it resolves the motion to dismiss, not until all appellate remedies are exhausted. Petitioner filed her motion to dismiss after the extended period for filing an answer had already lapsed; thus, she had no remaining time within which to file an answer. Under Rule 65, Section 7 of the Rules of Court, a petition for certiorari does not interrupt the principal case unless a temporary restraining order or writ of preliminary injunction is issued. The RTC respected the CA’s earlier TRO, and no injunctive relief was ordered by the Supreme Court in G.R. No. 126603. Petitioner’s repeated postponements and refusal to answer constituted a waiver of her right to present evidence; the trial court correctly proceeded to judgment. As to the collusion report, the public prosecutor had filed a Manifestation attesting to the absence of collusion. Moreover, the record showed vigorous opposition by petitioner, which negated any possibility of collusion. The non-intervention of the prosecutor is not fatal under Tuason v. Court of Appeals.

• Validity of the Second Marriage (Bigamy): The marriage between Senator Tamano and Zorayda, celebrated in 1958 under civil and Muslim rites, was governed by the Civil Code, which did not permit absolute divorce. P.D. 1083 took effect only on February 4, 1977, and Article 186(1) thereof explicitly provides for its prospective application, preserving the validity and effects of acts executed under prior laws. In G.R. No. 126603, the Court had already ruled that Article 13(1) of P.D. 1083 does not cover a situation where the parties were married both in civil and Muslim rites. The spouses never registered their mutual desire to convert the marriage under Article 186(2). Because the prior marriage was never dissolved, Senator Tamano’s subsequent marriage to petitioner was contracted during the subsistence of a valid marriage and is void ab initio for bigamy under Article 35(4) of the Family Code and Article 83 of the Civil Code.

• Standing to File the Nullity Suit: A.M. No. 02-11-10-SC, which limits the filing of a petition for declaration of nullity to the husband or wife, is prospective in application and does not govern a complaint filed in 1994. Before the Rule’s effectivity on March 15, 2003, any interested party could directly or collaterally attack a void marriage because such a marriage produces no legal effects and is not a source of rights. Additionally, even under the “aggrieved or injured spouse” standard, the prior spouse in a bigamous marriage is the injured party, as a bigamous second marriage threatens property rights and inflicts emotional harm; the subsequent spouse who benefits from the void marriage cannot be expected to initiate nullification. Adib, as a child and compulsory heir with a direct interest in the estate, likewise qualifies as a real party-in-interest.

• Prospective Application of the Code of Muslim Personal Laws (P.D. 1083) — Article 186(1) of P.D. 1083 embodies the general rule that the Muslim Code applies prospectively; acts executed prior to its effectivity are governed by the laws in force at the time, and nothing in the Code shall affect their validity or operate to extinguish rights already vested. A marriage validly celebrated under the Civil Code cannot be dissolved by divorce provisions introduced by the later Muslim Code. The Court applied this principle to bar the use of a Muslim divorce to terminate a 1958 civil-law marriage.

• Non-Suspensive Effect of a Certiorari Petition on the Principal Action — Under Rule 65, Section 7 of the Rules of Court, a petition for certiorari does not interrupt the course of the principal case unless a temporary restraining order or writ of preliminary injunction is issued. The pendency of such a petition, therefore, does not prevent the trial court from continuing with the proceedings and rendering judgment on the merits.

• Collusion Investigation in Nullity Cases Is Not Jurisdictional — While Article 48 of the Family Code and Rule 9, Section 3(e) require the public prosecutor to investigate collusion, the absence of a formal report does not invalidate the proceedings if the adversarial nature of the case itself demonstrates the lack of collusion and there is no allegation that evidence was suppressed or fabricated (citing Tuason v. Court of Appeals). Substantial compliance suffices.

• Standing to Attack a Void Marriage Before A.M. No. 02-11-10-SC — Prior to the effectivity of the Rule on Declaration of Absolute Nullity of Void Marriages (March 15, 2003), any interested party could attack a void marriage directly or collaterally, without prescription, because a void marriage produces no legal effects and cannot be the source of rights. The subsequent rule limiting standing to the spouses applies prospectively.

• “Injured Spouse” in Bigamous Marriages Under A.M. No. 02-11-10-SC — Even where the Rule applies, the prior spouse in a bigamous marriage is the “injured spouse” entitled to file the petition. To confine standing to the husband and wife of the subsequent void marriage would unjustly preclude the truly aggrieved party, as parties benefiting from a bigamous marriage would be unlikely to seek its nullification.

• “A new law ought to affect the future, not what is past. Hence, in the case of subsequent marriage laws, no vested rights shall be impaired that pertain to the protection of the legitimate union of a married couple.” — The decision’s opening paragraph, encapsulating the principle of prospectivity that decided the choice-of-law issue.

• “The petition shall not interrupt the course of the principal case unless a temporary restraining order or a writ of preliminary injunction has been issued against the public respondent from further proceeding in the case.” — Rule 65, Section 7, quoted to reject petitioner’s claim that the RTC should have suspended proceedings.

• “Should parties in a subsequent marriage benefit from the bigamous marriage, it would not be expected that they would file an action to declare the marriage void and thus, in such circumstance, the ‘injured spouse’ who should be given a legal remedy is the one in a subsisting previous marriage.” — The rationale for recognizing the prior spouse as the aggrieved party with standing to sue.

• “In a void marriage, in which no marriage has taken place and cannot be the source of rights, any interested party may attack the marriage directly or collaterally without prescription, which may be filed even beyond the lifetime of the parties to the marriage.” — Reaffirming the settled rule on void marriages before A.M. No. 02-11-10-SC.

• Tamano v. Hon. Ortiz, 353 Phil. 775 (1998) — Controlling precedent in G.R. No. 126603, holding that Article 13 of P.D. 1083 does not cover marriages celebrated under both civil and Muslim rites and that the RTC had jurisdiction. The ruling was followed here as law of the case on the jurisdictional and choice-of-law issues.

• Malang v. Judge Moson, 398 Phil. 41 (2000) — Followed for the doctrine that the Civil Code governs marriages celebrated before the effectivity of the Muslim Code and that the Muslim Code operates prospectively, preserving rights and obligations already vested.

• Judge Macias v. Macias, 457 Phil. 463 (2003) — Distinguished; it only requires suspension of trial until the trial court resolves the motion to dismiss, not until appellate review of that denial is exhausted.

• Tuason v. Court of Appeals, 326 Phil. 169 (1996) — Followed to hold that the lack of a prosecutor’s collusion investigation is not fatal when the adversary nature of the proceedings negates collusion.

• Niñal v. Bayadog, 384 Phil. 661 (2000) — Applied for the rule that any interested party may attack a void marriage directly or collaterally, even beyond the lifetime of the parties.

• Enrico v. Heirs of Medinaceli, G.R. No. 173614, September 28, 2007, 534 SCRA 418, and Carlos v. Sandoval, G.R. No. 179922, December 16, 2008, 574 SCRA 116 — Both cited to confirm that A.M. No. 02-11-10-SC applies prospectively and does not deprive parties of standing in cases filed before its effectivity.

• Article 35(4), Family Code — Declares bigamous or polygamous marriages not falling under Article 41 void from the beginning. Applied to adjudge the second marriage void ab initio.

• Article 83, Civil Code — Declares a subsequent marriage contracted during the subsistence of a prior marriage illegal and void unless the first was annulled or dissolved. The prior marriage was never dissolved; thus the second was void.

• Article 48, Family Code — Mandates the appearance of the prosecuting attorney to prevent collusion. Non-compliance was held not fatal under the circumstances, as the proceedings were adversarial.

• Rule 9, Section 3(e), Rules of Court — Requires the court, when the defendant in a nullity case fails to answer, to order the prosecuting attorney to investigate collusion. Held satisfied in substance.

• Rule 65, Section 7, Rules of Court — Provides that a certiorari petition shall not interrupt the principal case unless a temporary restraining order or writ of preliminary injunction is issued. Directly defeated petitioner’s claim that the trial court should have awaited the resolution of G.R. No. 126603.

• Presidential Decree No. 1083 (Code of Muslim Personal Laws), Articles 13(1), 186(1) and 186(2) — Article 13(1) on applicability: the Code does not apply to a marriage celebrated both in civil and Muslim rites. Article 186(1) mandates prospective application, preserving the effects of prior civil marriages. Article 186(2) allows conversion of a prior marriage to Muslim law only if the spouses register mutual consent, which did not happen.

• A.M. No. 02-11-10-SC, Section 2(a) — Limits the right to petition for declaration of nullity to the husband or wife. Construed as prospective, and in bigamy cases the prior spouse is recognized as the injured spouse with standing.
