Probable Cause and Preliminary Investigations: Safeguarding Rights in Criminal Proceedings

The Supreme Court’s 2016 decision in Pemberton v. De Lima (G.R. No. 217508, April 18, 2016) clarifies key principles in Philippine criminal procedure: what probable cause means, how preliminary investigations protect the accused, and why a court’s own finding of probable cause can render a challenge to the prosecutor's finding moot. The ruling is instructive for anyone facing or following a criminal case, as it delineates the distinct roles of prosecutors and judges.

The Facts of the Case

Joseph Scott Pemberton was charged with murder before the Olongapo City Prosecutor. During the preliminary investigation, the City Prosecutor ordered the collection of fingerprints and buccal swabs from Pemberton for forensic examination. Despite Pemberton’s objections and motions, the prosecutor found probable cause for murder and filed an Information in court. The trial court issued a warrant of arrest.

Pemberton appealed to the Secretary of Justice, who affirmed the finding of probable cause. He then went directly to the Supreme Court via a petition for certiorari, arguing that the Secretary committed grave abuse of discretion and denied him due process.

The Issue

The Court addressed three questions: (1) whether the Secretary of Justice committed grave abuse of discretion in affirming probable cause, (2) whether Pemberton violated the principle of hierarchy of courts by filing directly with the Supreme Court, and (3) whether the case had become moot.

Probable Cause: A Reasonable Belief, Not Certainty

The Court defined probable cause as “the existence of such facts and circumstances as would lead a person of ordinary caution and prudence to entertain an honest and strong suspicion that the person charged is guilty.” It requires “more than bare suspicion but less than evidence which would justify a conviction.” A finding of probable cause rests on evidence showing that “more likely than not, a crime has been committed by the suspect.”

Significantly, the Court ruled that absence of direct evidence does not preclude a finding of probable cause. Prosecutors may rely on circumstantial evidence, since crimes are often committed in secret. In this case, the Secretary of Justice based her finding on CCTV footage, witness identifications, physical examination results, and the presence of qualifying circumstances such as treachery, abuse of superior strength, and cruelty.

Due Process in Preliminary Investigations

Pemberton claimed he was denied due process because the prosecutor considered evidence he could not rebut. The Court disagreed, explaining that the essence of due process is “a reasonable opportunity to be heard.” Pemberton was given multiple chances: he was directed to file a counter-affidavit, he filed oppositions and motions, and he sought reconsideration. “When the party seeking due process was in fact given several opportunities to be heard. but it was by his own fault or choice that he squandered these chances, then his cry for due process must fail.”

The Doctrine of Hierarchy of Courts

The Court also reminded litigants that petitions for certiorari should generally be filed with the Court of Appeals, not directly with the Supreme Court. Direct resort to the Supreme Court is allowed only in exceptional cases—such as genuine constitutional issues, cases of first impression, or matters of transcendental importance. Pemberton’s argument that the trial was moving quickly was not a “special and important reason” to bypass the Court of Appeals.

Executive vs. Judicial Determination of Probable Cause

Perhaps the most important principle in the decision is the distinction between two kinds of probable cause:

• Executive determination – made by the prosecutor during preliminary investigation, to decide whether to file charges.
• Judicial determination – made by the judge, to decide whether to issue a warrant of arrest.

Once the Information is filed and the judge independently finds probable cause and issues a warrant, the court acquires jurisdiction over the case. Any challenge to the prosecutor's finding becomes moot. As the Court explained, “Once there has been a judicial finding of probable cause, an executive determination of probable cause is irrelevant.”

Practical Takeaways

• Probable cause is a low threshold. It requires reasonable belief, not proof beyond reasonable doubt. Direct evidence is not required; circumstantial evidence can suffice.
• Preliminary investigations protect the innocent. They are inquisitorial in nature, designed to shield the innocent from wrongful prosecution and to spare the state from useless trials.
• Due process means an opportunity to be heard. As long as the accused is given a chance to submit counter-affidavits and seek reconsideration, due process is satisfied—even if the accused chooses not to participate.
• Respect the hierarchy of courts. File petitions for certiorari with the Court of Appeals unless a compelling reason justifies direct resort to the Supreme Court.
• Judicial probable cause supersedes executive probable cause. Once a judge issues a warrant of arrest, the case belongs to the court, and the prosecutor's finding can no longer be questioned through certiorari.
