Why Prosecutors Must Present Evidence in Rape Cases: Lessons from Merciales v. Court of Appeals

The Supreme Court's 2002 decision in Merciales v. Court of Appeals (G.R. No. 124171) serves as a powerful reminder that in Philippine criminal procedure, the prosecution's duty to present evidence cannot be taken lightly. The case, which arose from the tragic death of Maritess Ricafort Merciales, illustrates what happens when a public prosecutor fails to fulfill this duty — and why the courts will step in to protect the rights of the offended party.

The Facts of the Case

In August 1993, six individuals were charged with rape with homicide before the Regional Trial Court of Legazpi City. During trial, the prosecution presented seven witnesses, but none of them actually witnessed the crime. The only potential eyewitness was one of the accused, Joselito Nuada, who offered to become a state witness.

The trial court ordered the prosecution to present evidence to justify Nuada's discharge as a state witness, as required by the Rules of Court. The public prosecutor refused, insisting that no such proof was needed because Nuada had already been admitted into the Witness Protection Program. The trial court denied the motion to discharge.

The Prosecution's Premature Resting of Its Case

What followed was a series of procedural missteps. The prosecution filed a petition for certiorari with the Supreme Court questioning the denial. Meanwhile, the accused moved to set the case for hearing, invoking their right to a speedy trial. The trial court granted this motion.

At the scheduled hearing, the prosecution again sought a continuance, which the court initially granted. But at the next hearing, the court directed the prosecutor to present an NBI agent who was present in court and could prove the due execution of Nuada's extrajudicial confession. Rather than comply, the prosecutor declared that the prosecution was resting its case — despite knowing the evidence was insufficient.

The accused then filed a demurrer to evidence, which the trial court granted, resulting in the acquittal of all accused.

The Supreme Court's Ruling

The Supreme Court reversed the acquittal, holding that both the public prosecutor and the trial court were guilty of serious nonfeasance. The Court emphasized several key principles:

First, a public prosecutor has a duty to pursue criminal actions and protect the public interest. Under Section 5, Rule 110 of the Rules of Court, all criminal actions shall be prosecuted under the direction and control of the public prosecutor. By deliberately refusing to present an available witness, the prosecutor failed in this duty.

Second, the trial court should have acted motu proprio (on its own motion) to call additional witnesses when it knew the prosecution's evidence was insufficient. The Court noted that a judge may question witnesses to satisfy his mind on particular facts or issues.

Third, the acquittal was void for lack of due process. The Court explained that when a judgment is rendered without regard to due process, it is null and void — as if no acquittal occurred at all. Consequently, the accused could not claim double jeopardy.

The Rule on State Witnesses

The Court also clarified the requirements for discharging an accused as a state witness. Under Rule 119, Section 9 (now Section 17) of the Rules of Court, the prosecution must present evidence and the sworn statement of each proposed state witness at a hearing. Mere admission into the Witness Protection Program does not excuse this requirement.

Practical Takeaways

• Prosecutors cannot shortcut the rules. The requirement to present evidence supporting a state witness discharge is mandatory, not optional.
• Judges have a duty to ensure fairness. A trial court that passively watches a prosecution fail may itself be guilty of nonfeasance.
• The offended party has rights. While private complainants generally cannot appeal an acquittal, they may challenge a void judgment, especially when the Solicitor General joins their cause.
• Double jeopardy does not protect void judgments. An acquittal rendered without due process is null and void and cannot bar re-prosecution.
• Due process applies to all parties. It is not only the State, but also the offended party, that is entitled to due process in criminal cases.
