The Supreme Court, in People v. Castillo, clarified the boundaries between executive and judicial determinations of probable cause. The Court emphasized that trial courts should generally defer to a prosecutor’s finding of probable cause unless the information is facially invalid or the prosecutor acted with manifest error or grave abuse of discretion. This decision reinforces the principle of prosecutorial discretion within the Philippine justice system, ensuring that courts do not unduly interfere with the Ombudsman’s constitutionally mandated powers.

When the Fence Becomes the Focus: Questioning Undue Interference

The case originated from a dispute over the closure of stalls in front of SM Bacoor, Cavite. Complainant Cesar Sarino alleged that respondents Jessie B. Castillo, the Municipal Mayor, and Felicito R. Mejia, the Municipal Building Official, caused undue injury by erecting a galvanized iron fence that blocked and fenced off Sarino’s property. This action, Sarino claimed, deprived him of the full use and enjoyment of his property, leading to significant financial losses. The central legal question was whether the Sandiganbayan erred in overturning the Ombudsman’s determination of probable cause, effectively dismissing the case against Castillo and Mejia.

The heart of the issue lies in the distinct roles of the public prosecutor and the judge in determining probable cause. The Supreme Court delineated between two types of probable cause determination: executive and judicial. Executive determination, occurring during the preliminary investigation, is the domain of the public prosecutor. This official has the discretion to decide whether sufficient evidence exists to charge an individual with a crime. The Court emphasized that trial courts should not typically interfere with this determination.

Whether or not that function has been correctly discharged by the public prosecutor, i.e., whether or not he has made a correct ascertainment of the existence of probable cause in a case, is a matter that the trial court itself does not and may not be compelled to pass upon.

Judicial determination, conversely, is made by a judge to decide whether to issue a warrant of arrest. The judge assesses whether there is a need to place the accused in custody to ensure justice is served. This assessment is confined to the necessity of an arrest warrant and does not extend to overriding the prosecutor’s decision to bring charges. The Supreme Court underscored the importance of respecting the public prosecutor’s discretion, especially when the information filed is valid and free from manifest error or grave abuse of discretion.

The Court cited Schroeder v. Saldevar, reinforcing the principle that courts must respect the prosecutor’s wide latitude of discretion in determining whether to file a criminal case.

…courts must respect the exercise of such discretion when the information filed against the person charged is valid on its face, and that no manifest error or grave abuse of discretion can be imputed to the public prosecutor.

In this case, the informations filed against Castillo and Mejia were deemed valid, complying with Section 6, Rule 110 of the Rules of Court. The Ombudsman’s resolution, which led to the filing of the original information, was supported by substantial evidence. Each element of Section 3(e) of Republic Act No. 3019, the Anti-Graft and Corrupt Practices Act, was meticulously explained. The Court found that the Sandiganbayan had erred by conducting its own executive determination of probable cause, thereby overstepping its judicial role.

Furthermore, the Supreme Court found the Sandiganbayan’s pre-trial determination of the respondents’ lack of bad faith and the absence of undue injury to the complainant as premature. The Court emphasized that the presence or absence of these elements are evidentiary matters best assessed during a full trial.

…it is well established that the presence or absence of the elements of the crime is evidentiary in nature and is a matter of defense that may be best passed upon after a full-blown trial on the merits.

The Court cited Go v. Fifth Division, Sandiganbayan, to support this point, stressing that expecting the prosecution to present all evidence necessary for conviction at the information stage is unrealistic, given the limited scope of a preliminary investigation. The Supreme Court emphasized its standing policy of non-interference in the Ombudsman’s exercise of constitutionally mandated powers, citing both respect for these powers and the practical need to prevent the courts from being overwhelmed by petitions challenging prosecutorial decisions.

To further clarify the roles, consider this comparative table:

Aspect	Executive Determination (Public Prosecutor)	Judicial Determination (Judge)
Purpose	To decide whether to file criminal charges	To decide whether to issue a warrant of arrest
Scope	Broad discretion to assess evidence and determine probable cause	Limited to assessing the necessity of an arrest warrant
Interference	Courts should generally defer unless information is invalid or there is manifest error	Can refuse to issue warrant if probable cause is lacking
