Donio-Teves vs. Vamenta, Jr.

In the prosecution of adultery under Article 333 of the Revised Penal Code, the complaint required by Article 344 is satisfied by a formal complaint filed with the court (not merely the fiscal's office) that states the essential requisites under Rule 110 and is subscribed and sworn to by the offended party; once this complaint is filed, the subsequent death of the complainant does not extinguish criminal liability or terminate the proceedings, as the offended party's role is limited to initiating the action to protect his/her privacy, while the State maintains the prosecution to vindicate public order.

Adultery is classified as a "private crime" under the Revised Penal Code, meaning it cannot be prosecuted de oficio and requires a complaint initiated by the offended spouse. The requirement exists to protect the aggrieved party from the scandal of public trial if they prefer to suffer the outrage in silence. However, the case addresses the procedural confusion between the complaint needed to start preliminary investigation versus the complaint required to vest jurisdiction in the trial court, as well as the effect of the complainant's death on ongoing proceedings.

• July 13, 1972: Complainant Julian L. Teves filed a letter-complaint with the City Fiscal of Dumaguete, thumbmarked and sworn, attaching witness affidavits
• January 16, 1973: Complainant filed a second letter-complaint with the Fiscal, also thumbmarked and sworn, amplifying the first complaint
• March 26, 1973: An information was filed with the Court of First Instance (CFI) of Negros Oriental (docketed as Criminal Case No. 1097), attaching a complaint thumbmarked and sworn to by complainant
• September 28, 1973: Petitioners filed a Motion to Quash challenging jurisdiction and the validity of the complaint; motion denied by respondent Judge on December 3, 1973; reconsideration denied on January 14, 1974
• April 14, 1974: Complainant Julian L. Teves died during the pendency of the proceedings
• Instant Petition: Filed for certiorari, prohibition, and mandamus seeking to annul all proceedings; SC dismissed the petition

• Petitioner Milagros Donio-Teves is the wife of complainant Julian L. Teves; petitioner Manuel Moreno is the alleged paramour
• The offended spouse filed multiple complaints: (1) initial letter-complaint dated July 13, 1972 with the City Fiscal; (2) second letter-complaint dated January 16, 1973 with the Fiscal; and (3) formal complaint dated March 26, 1973 filed with the CFI
• All complaints were thumbmarked (not signed with a pen) by the complainant and sworn to before the City Fiscal
• The March 26, 1973 complaint filed with the CFI designated the offense as "Adultery," named the accused, stated the acts occurred between May 1970 to December 1970 in Dumaguete City, and alleged sexual intercourse between the accused
• Petitioners were charged under Article 333 of the RPC (adultery)
• Complainant died on April 14, 1974 while the case was pending and before the instant SC petition was resolved

• The letter-complaint filed with the City Fiscal was insufficient to initiate prosecution because it lacked a proper signature (only thumbmarked) and did not strictly comply with the formal requisites of a complaint under Article 344 of the RPC
• The City Fiscal lacked jurisdiction to conduct preliminary investigation due to the defective complaint
• The thumbmarked complaint filed with the CFI was similarly invalid as it was not "signed" by the complainant as required by Section 5, Rule 110 of the Rules of Court
• The death of the complainant on April 14, 1974 extinguished criminal liability and rendered the continuation of the prosecution moot, as adultery is a private crime requiring the offended party's continued participation

• N/A (The SC decision does not explicitly enumerate separate arguments for the respondents; the case was resolved based on the SC's independent evaluation of the petitioners' claims and the applicable law)

• Procedural Issues: Whether the thumbmarked and sworn complaints filed with the City Fiscal and the CFI satisfied the jurisdictional requirement of a "complaint by the offended party" under Article 344 of the RPC and Section 5, Rule 110 of the Rules of Court
• Substantive Issues:
  • Whether the death of the offended party during the pendency of the case extinguishes the criminal liability of the accused for adultery
  • Whether the requirement of a complaint by the offended party applies to the preliminary investigation stage or only to the filing of the information in court

• Procedural: The SC ruled that the complaints filed were sufficient and valid. The second complaint dated January 16, 1973 filed with the Fiscal's Office and the complaint dated March 26, 1973 filed with the CFI both stated the names of the defendants, designated the offense, described the acts constituting the offense, named the offended party, and stated the approximate time and place of commission. Both were thumbmarked and sworn to by the complainant, satisfying the requisites of Article 344 and Rule 110. The SC clarified that while strict compliance is required for the court complaint, a letter-complaint suffices to start preliminary investigation.
• Substantive:
  • Death of complainant: The death of the offended party is not a ground for extinguishment of criminal liability under Article 89 of the RPC. The participation of the offended party is essential only for the initiation of the criminal action, not for its maintenance. Once a valid complaint is filed, the will of the offended party is ascertained, and the action proceeds in the name of the State to vindicate public order, regardless of the complainant's subsequent death.
  • Nature of "private crimes": The term "private crimes" is misleading. While the offended spouse has the option to initiate prosecution to avoid scandal, once the choice is made and a complaint filed, the law applies in full force beyond the control of the complainant. The State has an independent interest in prosecuting the offense because every violation of penal laws disturbs public order and safety.

• Initiation vs. Maintenance of Criminal Actions in Private Crimes — In crimes that cannot be prosecuted de oficio (such as adultery under Article 344), the offended party's complaint is required solely to initiate the prosecution, not to maintain it. Once the complaint is filed, the case proceeds despite the complainant's death, withdrawal, or pardon, because the State is also an offended party seeking to vindicate public order.
• Sufficiency of Complaint for Adultery — A complaint for adultery must comply with Section 5, Rule 110 of the Rules of Court: (1) name of the accused; (2) designation of the offense by the statute; (3) acts or omissions constituting the offense; (4) name of the offended party; (5) approximate time of commission; and (6) place where the offense was committed. The complaint filed with the court (not merely the preliminary investigation complaint) must satisfy these requisites and be subscribed and sworn to by the offended party.
• Strict Construction of Article 344 — The SC adheres to strict compliance with the jurisdictional requirement of a complaint by the offended party for private crimes. However, the "spirit rather than the letter" prevails where the complainant's intent to prosecute is unequivocally demonstrated, as in this case where three separate complaints were filed to meet procedural objections.

• "The term 'private crimes' in reference to felonies which cannot be prosecuted except upon complaint filed by the aggrieved party, is misleading. Far from what it implies, it is not only the aggrieved party who is offended in such crimes but also the State."
• "The participation of the offended party is essential not for the maintenance of the criminal action but solely for the initiation thereof."
• "It is the spirit rather than the letter of the law which should prevail."
• "Once a complaint is filed, the will of the offended party is ascertained and the action proceeds just as in any other crime... the law will be applied in full force beyond the control of, and in spite of the complainant, his death notwithstanding."

• People v. Ilarde, 125 SCRA 11 — Cited for the principle that the spirit rather than the letter of the law should prevail in determining whether the condition precedent of a complaint has been complied with.
• People v. Santos, 101 Phil. 798 — Cited to distinguish between the complaint required for preliminary investigation (letter-complaint suffices) versus the complaint required for filing with the court.
• People v. Palabao, G.R. No. L-80027, August 31, 1954 — Cited as precedent where an information signed by the offended party at the bottom (over the fiscal's signature) was held insufficient for lack of proper complaint.
• People v. Martinez, 76 Phil. 559 — Cited for the SC's power to motu proprio dismiss cases for failure to file the proper complaint for offenses that cannot be prosecuted de oficio.
• U.S. v. Gomez, 12 Phil. 279; U.S. v. Narvasa, 14 Phil. 410; U.S. v. dela Cruz, 17 Phil. 139; U.S. v. Castanares, 18 Phil. 210; U.S. v. Salazar, 19 Phil. 233 — Early Philippine cases cited for the strict adherence to the requirement of a complaint by the offended party for private crimes.

• Article 333 of the Revised Penal Code — Defines and penalizes adultery (sexual intercourse by a married woman with a man not her husband, knowing she is married).
• Article 344 of the Revised Penal Code — Requires that adultery "cannot be prosecuted except upon a complaint filed by the offended spouse who cannot institute the criminal prosecution without including both the guilty parties, if they are both alive, nor in any case, if he shall have consented or pardoned the offenders."
• Article 89 of the Revised Penal Code — Enumerates grounds for total extinguishment of criminal liability; death of the offended party is not included.
• Article 94 of the Revised Penal Code — Enumerates grounds for partial extinguishment of criminal liability.
• Section 5, Rule 110 of the Rules of Court — Prescribes the requisites of a valid complaint or information (name of accused, designation of offense, acts/omissions, name of offended party, time and place of commission).
• Section 2, Rule 106 of the Rules of Court (now Rule 110) — Historical reference to the requirement of a complaint for offenses requiring the offended party's initiative.

• Aquino, J. (Concurring) — Stated briefly that the motion to quash was "obviously dilatory" and that the instant petition should not have been given due course.
