In Philippine jurisprudence, the principle of mootness dictates that a court should not decide a case if there is no actual, substantial relief to be granted. This principle is particularly relevant in challenges to preliminary investigations. The Supreme Court has consistently held that once an information (the formal charge) is filed in court based on a preliminary investigation, and the trial court issues a warrant of arrest upon finding probable cause, any question about the regularity or validity of the preliminary investigation becomes moot. The focus shifts to the trial court’s assessment of the case’s merits. This protects the integrity of the judicial process by preventing courts from ruling on issues that no longer affect the parties’ rights.

Atimonan Encounter: Can Preliminary Doubts Halt Justice After Charges Are Filed?

The case of Police Superintendent Hansel M. Marantan v. Department of Justice stemmed from the controversial Atimonan Encounter, where 13 individuals were killed in a shootout involving police and military personnel. Marantan, a police superintendent involved in the incident, sought to halt the preliminary investigation conducted by the Department of Justice (DOJ), alleging bias due to public statements made by the then-Secretary of Justice, Leila De Lima. Marantan argued that these statements prejudiced his right to an impartial investigation and equal protection under the law. However, before the Supreme Court could rule on the merits of Marantan’s claims regarding the impartiality of the preliminary investigation, the DOJ concluded its investigation, found probable cause, and filed an information against Marantan for multiple murder in the Regional Trial Court (RTC). The RTC subsequently issued a warrant for his arrest.

The Supreme Court, in its decision, addressed several key issues, including whether the case constituted an exception to the rule on judicial hierarchy and the principle of exhaustion of administrative remedies. The Court emphasized that direct invocation of its original jurisdiction is reserved for cases with special and important reasons. The court noted that grave abuse of discretion, the very basis of Marantan’s petition, did not automatically warrant direct recourse to the Supreme Court, especially when the Court of Appeals could also grant the relief sought. Furthermore, Marantan failed to file a motion for reconsideration before elevating the case to the Supreme Court, violating the principle of exhaustion of administrative remedies. The Court found no compelling reason to waive this requirement, reinforcing the importance of allowing administrative bodies the opportunity to correct their own errors before judicial intervention.

The Supreme Court also addressed Marantan’s claim of bias on the part of the DOJ. Marantan argued that public pronouncements by the Secretary of Justice prejudiced his right to due process, rendering the preliminary investigation unfair. The Court referenced the case of Cojuangco, Jr. v. Presidential Commission on Good Government, which established that impartiality is a requisite of due process in preliminary investigations. However, the Supreme Court distinguished the present case, noting that unlike the PCGG in Cojuangco, the DOJ did not have a vested interest against Marantan from the outset. While acknowledging that the Secretary of Justice’s conduct could have been more circumspect, the Court found no evidence of ulterior motives or demonstrable bias that tainted the investigation. The Court highlighted that the DOJ’s investigation, conducted through the National Bureau of Investigation (NBI), was within its mandate to investigate crimes and offenses of public interest, as per Republic Act No. 157.

The Court further emphasized that to warrant judicial intervention, the alleged irregularities in the preliminary investigation must have fundamentally deprived the accused of the opportunity to be heard, or the infirmities must be so fatal as to deprive the accused of a fair chance during judicial examination, pre-trial, and trial. In this case, Marantan failed to demonstrate that the DOJ’s findings of probable cause were erroneous or tainted with grave abuse of discretion. The Court noted that the Panel of Prosecutors presented well-reasoned, evidence-based conclusions to support its finding of probable cause for murder. The Panel identified several suspicious circumstances surrounding the Atimonan Encounter, including the irregular setup of the checkpoint, the absence of a legitimate firefight as indicated by forensic evidence, and the attempt to tamper with evidence.

The Supreme Court ultimately ruled that the filing of the information against Marantan in the Regional Trial Court rendered the petition moot. Citing the landmark case of Crespo v. Mogul, the Court reiterated that once an information is filed in court, the court acquires jurisdiction over the case, and it is the trial court’s prerogative to determine the accused’s guilt or innocence. As such, any decision on whether the DOJ should have inhibited itself from the preliminary investigation would be of no practical value, as the matter was already within the jurisdiction of the trial court. The Court stated:

Here, an information against petitioner has already been filed before the Regional Trial Court. Consequently, whether the case should be dismissed, or whether petitioner should be acquitted or convicted, is for the trial court to determine. Resolving whether public respondent Department of Justice should have inhibited from conducting the preliminary investigation and forwarded the case records to the Office of the Ombudsman would be of no practical use and value here.

The decision in Marantan v. Department of Justice reinforces the principle that once a criminal case is filed in court based on a preliminary investigation, the focus shifts to the trial court’s jurisdiction, rendering challenges to the preliminary investigation moot. This ruling underscores the importance of adhering to procedural rules such as judicial hierarchy and exhaustion of administrative remedies. Litigants must exhaust available remedies and demonstrate exceptional circumstances before directly seeking relief from the Supreme Court.

Building on this principle, the Court emphasizes that allegations of bias must be substantiated with concrete evidence showing that the investigating body acted with prejudice or ulterior motives. Mere public statements or prior investigations by the same agency are insufficient to establish bias. Furthermore, the decision serves as a reminder that preliminary investigations are primarily intended to determine whether there is sufficient basis to file charges and prevent harassment suits, and are not meant to be full-blown trials. Therefore, any alleged irregularities must be so egregious as to deprive the accused of a fair opportunity to be heard during the subsequent judicial proceedings.

FAQs

What was the key issue in this case?	The key issue was whether the Department of Justice (DOJ) committed grave abuse of discretion during the preliminary investigation against Police Superintendent Hansel M. Marantan, and whether the filing of an information in court rendered the petition questioning the preliminary investigation moot.
What is a preliminary investigation?	A preliminary investigation is an inquiry or proceeding to determine whether there is sufficient ground to engender a well-founded belief that a crime has been committed and that the respondent is probably guilty thereof, and should be held for trial. It is not a trial on the merits but rather a means of determining probable cause.
What does it mean for a case to be moot?	A case becomes moot when it ceases to present a justiciable controversy because of supervening events, such that a declaration by the court would be of no practical use or value. In legal terms, the issue is no longer relevant.
Why did the Supreme Court dismiss Marantan’s petition?	The Supreme Court dismissed the petition because the filing of the information against Marantan in the Regional Trial Court (RTC) rendered the issues regarding the preliminary investigation moot. The RTC’s jurisdiction over the case meant the validity of the preliminary investigation was no longer relevant.
What did Marantan allege was wrong with the preliminary investigation?	Marantan alleged that the Department of Justice (DOJ) was biased against him due to public pronouncements made by the Secretary of Justice, and that this bias tainted the entire preliminary investigation process.
What is the principle of exhaustion of administrative remedies?	The principle of exhaustion of administrative remedies requires parties to avail themselves of all administrative processes available before seeking judicial intervention. In this case, Marantan failed to file a motion for reconsideration with the DOJ before filing his petition with the Supreme Court.
What is the rule on judicial hierarchy?	The rule on judicial hierarchy directs that cases should be filed with the lower courts first before elevating them to higher courts. Marantan directly filed his petition with the Supreme Court without first seeking relief from the Court of Appeals.
What was the legal basis for the DOJ’s authority to investigate?	The DOJ’s authority to investigate the Atimonan Encounter stemmed from its mandate to investigate crimes and offenses of public interest, as provided by Republic Act No. 157.
What is the significance of the Crespo v. Mogul case?	The Crespo v. Mogul case established that once an information is filed in court, the court acquires jurisdiction over the case, and it is the court’s prerogative to determine the accused’s guilt or innocence, rendering challenges to the preliminary investigation moot.

In conclusion, the Supreme Court’s decision in Marantan v. Department of Justice reinforces the importance of procedural rules and the principle of mootness in Philippine law. Once a case is properly within the jurisdiction of a trial court, challenges to the preliminary stages of the investigation become irrelevant, ensuring the efficient administration of justice.
