Case Summary (G.R. No. 222105)

Key Dates and Procedural Milestones

June 15, 2010 (incident); February 9, 2012 (Information filed as Criminal Case No. 2747‑N before the 1st Municipal Circuit Trial Court (MCTC)); March 6, 2012 (MCTC ordered prosecution to submit additional proof); June 5, 2012 (MCTC dismissed the case for lack of probable cause); August 10, 2012 (MCTC denied motion for reconsideration); September 9, 2013 (RTC granted certiorari, reversed MCTC, and reinstated the Information); April 30, 2015 and October 27, 2015 (Court of Appeals Decision and Resolution affirming RTC); December 13, 2023 (Supreme Court decision denying the consolidated petitions).

Applicable Law and Legal Standards

Governing constitutional framework: 1987 Philippine Constitution (decision rendered after 1990). Controlling procedural law: Rule 112, Sections 5 and 6 of the Rules of Criminal Procedure (judicial determination of probable cause and issuance of warrant of arrest). Doctrinal points: (1) Adultery is a so‑called private crime that may only be initiated by the offended husband; (2) the prosecutor’s finding of probable cause is an executive function to determine whether to file an Information; (3) the judge’s inquiry on probable cause is a separate judicial function and must not require proof sufficient for conviction; (4) a trial court may dismiss only if the evidence on record clearly fails to establish probable cause.

Proceedings in the MCTC

The MCTC issued an order on March 6, 2012 directing the prosecution to submit additional supporting evidence within five days to assist the court’s probable‑cause determination. The prosecution did not comply. On June 5, 2012 the MCTC dismissed the case for lack of probable cause and later denied a motion for reconsideration, prompting Peter to file a Rule 65 petition for certiorari in the RTC alleging grave abuse of discretion.

RTC Ruling on Certiorari

The RTC (Branch 4, Kalibo) granted Peter’s petition for certiorari on September 9, 2013, holding that the MCTC gravely abused its discretion in dismissing the case. The RTC emphasized that the OPP’s earlier Resolution finding probable cause could not be disregarded and reiterated that probable cause requires only a reasonable belief that a crime has been committed and that the accused probably committed it, not proof beyond reasonable doubt. The RTC reinstated the Information and directed the MCTC to take cognizance of the case.

Court of Appeals Ruling

The Court of Appeals affirmed the RTC’s decision, finding that the MCTC judge improperly demanded evidence (e.g., photographs, proof of kissing or hugging, love letters) that would be necessary to secure a conviction rather than to establish probable cause. The CA agreed that the evidence filed with the OPP—affidavits, witness statements, recorded interviews, and the circumstances of the arrest—was sufficient to support a reasonable belief that adultery had likely occurred.

Issues Presented to the Supreme Court

Principal contested questions included: (1) whether Peter, as private complainant, had the legal personality to file a petition for certiorari under Rule 65 challenging the MCTC’s dismissal without the concurrence of the public prosecutor; and (2) whether the CA gravely erred in affirming the RTC’s finding that the MCTC abused its discretion for requiring proof appropriate only at trial and for disregarding the OPP’s Resolution.

Supreme Court Analysis — Legal Personality of the Private Complainant

The Court held that Peter possessed the legal personality to file a special civil action for certiorari in the RTC to challenge the MCTC’s dismissal on jurisdictional grounds and to protect his interest in the civil aspect of the criminal case. The Court distinguished the right to initiate a private‑crime complaint (vested in the offended party) from the authority to prosecute (vested in the State through the prosecutor). Once the complaint is filed, the State, via the public prosecutor, assumes the principal prosecutorial role. Nevertheless, because certiorari is an original, independent remedy directed at jurisdictional errors and not an appeal of the criminal ruling itself, the private complainant may properly institute certiorari in the RTC when no plain, speedy, and adequate remedy exists to safeguard the private complainant’s civil interest.

Supreme Court Analysis — Limits on Private Complainant’s Remedies and Guidelines

The Court reaffirmed that, as a rule, only the public prosecutor may appeal criminal judgments or interlocutory rulings affecting the criminal aspect; the private complainant may appeal only the civil component. Citing and restating the guidelines from the Austria v. AAA line of cases, the Court directed that when a private complainant files an appeal or petition affecting the criminal aspects before the RTC, the RTC must require the provincial or city prosecutor to file a comment within a non‑extendible 30‑day period if resolution of the private complainant’s remedy will necessarily affect the criminal aspect or the right to prosecute. The Court reiterated: (1) the private complainant may file certiorari alleging a specific pecuniary interest; (2) the private complainant lacks standing to challenge criminal aspects without the prosecutor’s conformity; (3) the RTC must solicit the provincial/city prosecutor’s comment within 30 days on petitions that question dismissal, acquittal, or interlocutory orders on grounds like grave abuse; and (4) those guidelines apply prospectively and ensure the State, through its prosecutors, is heard when the criminal interest is implicated.

Supreme Court Analysis — Probable Cause and Judicial Review

The Court explained the delineation of functions: the public prosecutor’s finding of probable cause is executive (for filing the Information); the judge’s determination is judicial (to decide need for custody). Under Section 5, Rule 112, a judge has three discrete o
