ADULTERY CASES CAN BE FILED ONLY BY THE OFFENDED PARTY—SUPREME COURT
The Supreme Court (SC) has junked an adultery case, noting that under the law, the offense is classified as a private crime and that only the offended spouse has the legal standing to initiate and file a criminal complaint.
In a 9-page decision penned by Associate Justice Antonio T. Kho, Jr., the SC’s Second Division reversed the ruling of the Regional Trial Court (RTC), which had ordered the reinstatement of the adultery case against Aurel Ann Chua-Chiba and Michael Llona.
In 2022, Aurel’s husband, Jin Chiba through his authorized representative, Marvin Ayende filed a complaint affidavit charging Aurel Ann and Michael Llona of the crimes of adultery and grave threats before the Office of the City Prosecutor, Pasay City.
Following a preliminary investigation, the prosecutor found probable cause to indict Aurel and Michael of adultery and grave threats. As a result, they face grave threats and adultery complaints.
The lower court issued the corresponding warrant of arrest with a recommended PHP 36,000.00 bail against them. Subsequently, Aurel and Michael posted cash bonds for their provisional liberty.
Aurel filed a motion to dismiss before the Metropolitan Trial Court (MeTC) seeking the dismissal of the adultery case on the ground of lack of jurisdiction, as the case cannot be prosecuted by a complete stranger even if aided by a special power of attorney, and the grave threats case in view of the alleged deprivation of due process.
The MeTC granted the petition and dismissed the adultery charge, citing that only the offended spouse can initiate it. The RTC overturned the MeTC’s decision, confirming that the filing met legal standards because Jin’s complaint-affidavit was actually attached to the complaint submitted by his representative. Dissatisfied, Aurel took a direct recourse before the Supreme Court.
In reversing the RTC decision, the high court cited Rule 110, Section 5, of the Revised Rules of Criminal Procedure and Article 344 of the Revised Penal Code (RPC), which provides that adultery and concubinage are private crimes that may be prosecuted only upon a complaint filed by the offended spouse.
It noted that this requirement exists “out of consideration for the aggrieved party who might prefer to suffer the outrage in silence rather than go through the scandal of a public trial.” The law allows the offended spouse to decide whether to bring the matter to court or handle it privately.
The SC explained that in the case of Aurel, the complaint for adultery was not initiated by the offended spouse but by his representative. Although Jin submitted his own complaint-affidavit, it was only included as an annex to his representative’s complaint.
"Therefore, since no valid complaint for adultery was filed against Aurel and Michael, the MeTC Pasay City-Branch 167 was correct in granting the motion to dismiss," the Supreme Court added.
