G.R. No. 190969 ; January 30, 2013
BARON A. VILLANUEVA and the SECRETARY OF JUSTICE, Petitioners, vs. EDNA R. CAPARAS, Respondent.

FACTS

An altercation occurred between Renato Caparas and petitioner Baron Villanueva on August 24, 2005, resulting in Renato’s death. Respondent Edna Caparas, Renato’s wife, filed a criminal complaint for murder. After preliminary investigation, the Quezon City Prosecutor found probable cause and filed an Information for Homicide against Villanueva. Villanueva filed a petition for review with the Secretary of Justice, who reversed the prosecutor’s finding, directed the withdrawal of the Information, and ruled the evidence insufficient for a prima facie case. Edna Caparas then filed a Rule 65 petition for certiorari with the Court of Appeals.
The Court of Appeals granted the petition, reversed the Secretary of Justice’s resolution, and ordered the reinstatement of the prosecutor’s resolution and the Information. The CA held that the Secretary committed grave abuse of discretion by exceeding the scope of a preliminary investigation, which is merely to determine probable cause, not to rule on the validity of defenses or the weight of evidence, matters best left for trial. Villanueva’s subsequent motion for reconsideration was denied, prompting this petition.

ISSUE

Whether the Court of Appeals correctly ruled that the Secretary of Justice committed grave abuse of discretion in reversing the prosecutor’s finding of probable cause.

RULING

The Supreme Court denied the petition and affirmed the decision of the Court of Appeals. The legal logic is anchored on the nature and purpose of a preliminary investigation and the limited scope of judicial review over executive determinations of probable cause. Probable cause is defined as facts and circumstances sufficient to engender a well-founded belief that a crime has been committed and the respondent is probably guilty. It implies probability, not certainty, and requires only evidence sufficient to establish a prima facie case.
While the determination of probable cause is an executive function primarily vested in the prosecutor and reviewable by the Secretary of Justice, such findings are generally not subject to judicial interference. However, courts may intervene through a writ of certiorari when the Secretary acts with grave abuse of discretion—that is, when the action is done in a capricious, whimsical, or despotic manner equivalent to lack of jurisdiction. The Supreme Court found that the Secretary did precisely that by delving into matters essentially evidentiary, such as assessing the credibility of affidavits and the conflict between the autopsy report and an NBI medico-legal opinion. These are matters of defense whose validity and weight are proper for full examination during trial, not for resolution at the preliminary investigation stage. The prosecutor’s finding was based on sufficient evidence, including an eyewitness account, to establish probable cause for Homicide. Therefore, the Secretary’s reversal constituted a grave abuse of discretion, correctly rectified by the Court of Appeals.
