b. Judicial Non-interference

Judicial Non-interference in the Prosecutor’s Determination

Concept

The decision whether to charge a respondent after preliminary investigation belongs in the first instance to the prosecution. Courts ordinarily do not substitute their assessment of probable cause for the prosecutor’s. Judicial restraint, however, does not remove the courts’ power to correct grave abuse of discretion. (Callo-Claridad v. Esteban, G.R. No. 191567, 20 March 2013)¹ (Ampatuan v. Justice, G.R. No. 200106, 22 February 2023)²

Governing provisions

Under Rule 112, the investigating prosecutor prepares a resolution and information if there is cause to hold the respondent for trial; otherwise, the prosecutor recommends dismissal. Filing or dismissal requires the prior written authority or approval of the designated supervising prosecutor or official. Under the 2024 DOJ-NPS Rules, the investigating prosecutor recommends filing when the evidence meets the stated standard of prima facie evidence with reasonable certainty of conviction, while dismissal requires the authority or approval of the head of the prosecution office. (Rule 112, Sec. 4, Rules of Court)³ (Sec. 16, 2024 DOJ-NPS Rules on Preliminary Investigations and Inqu…)⁴

Requisites / Rules

• General rule. A court does not disturb the Executive’s finding of probable cause merely because it would assess the evidence differently. Review asks whether the prosecution gravely abused its discretion; the court does not determine prosecutorial probable cause anew. (Callo-Claridad v. Esteban)¹ (Ampatuan v. Justice)²
• Threshold for intervention. Grave abuse must be clearly shown; it must be patent and gross enough to amount to an evasion of duty. Factual disputes and the determination of guilt beyond reasonable doubt belong to trial, not to judicial re-evaluation of the preliminary investigation. (Callo-Claridad v. Esteban)¹ (Ampatuan v. Justice)²
• Executive supervision. Prosecutorial recommendations remain subject to the approval and review mechanisms within the prosecution service. The Secretary of Justice’s review of a prosecutor’s probable-cause finding is an executive function, distinct from a court’s determination. (Rule 112, Sec. 4, Rules of Court)³ (Callo-Claridad v. Esteban)¹ (Lima v. Reyes, G.R. No. 209330, 11 January 2016)⁵

Distinctions

Executive versus judicial probable cause. The prosecutor’s executive determination concerns whether to charge the respondent. After an information is filed, the judge independently determines judicial probable cause for purposes of an arrest warrant. In doing so, the trial court does not sit as an appellate court reviewing the prosecutor’s finding. (People v. Omelio, G.R. No. 229705, 14 July 2021)⁶ (Mendoza v. People, G.R. No. 197293, 21 April 2014)⁷

Key doctrines

Filing the information terminates preliminary investigation and places the case within the trial court’s jurisdiction. Once the court has judicially determined probable cause, a challenge directed only at the preliminary investigation may become moot; an inquiry into whether the Secretary of Justice gravely abused discretion in deciding to charge may then have no practical value. (Lima v. Reyes)⁵ (People v. Omelio)⁶

Respect for executive determination also applies to the DOJ’s rules governing preliminary investigations and inquests. The DOJ may make rules within the executive sphere, while the Supreme Court retains supremacy over rules of court and the power to correct, for grave abuse of discretion, a prosecutorial rule or action that impairs constitutional rights. (Meking v. Remulla, G.R. No. 280455, 11 November 2025)⁸

Exceptions

Non-interference is not absolute. A court may intervene upon a clear showing of grave abuse of discretion in the Executive’s determination. Separately, after an information is filed, a judge’s independent assessment may support dismissal when the evidence absolutely fails to establish probable cause; that assessment is not an appeal from the prosecutor’s resolution. (Callo-Claridad v. Esteban)¹ (Mendoza v. People)⁷ (People v. Omelio)⁶

Bar tip

Identify whose probable-cause determination is challenged and whether an information has already been filed. Apply grave-abuse review to the prosecutor’s determination; do not confuse it with the judge’s independent warrant inquiry. (Ampatuan v. Justice)² (People v. Omelio)⁶
