State Witness Exclusion: Balancing Prosecutorial Discretion and Court Oversight

The Supreme Court’s 2005 decision in Soberano v. People (G.R. No. 154629) settles a recurring tension in Philippine criminal procedure: how far may a prosecutor go in amending an information to exclude some accused so they can become state witnesses, and when must a trial court intervene? The ruling, arising from the high-profile Dacer-Corbito double murder case, draws a clear line between the executive’s power to prosecute and the judiciary’s duty to protect the rights of the accused.

The Dacer-Corbito Case

In November 2000, public relations practitioner Salvador “Bubby” Dacer and his driver Emmanuel Corbito were abducted in Manila. Their charred remains were later found in Indang, Cavite; both had been killed by strangulation. The Department of Justice (DOJ) charged over twenty individuals—mostly police officers—with double murder before the Regional Trial Court of Manila.

After the filing of the original Information, the prosecution moved for reinvestigation, which the trial court granted. Following reinvestigation, the prosecution filed a Motion to Admit Amended Information that (1) excluded four accused—Jimmy Lopez, William Lopez, Alex Diloy, and Glen Dumlao—to serve as state witnesses, (2) substituted one accused, and (3) added three new accused, including Michael Ray Aquino and Cezar Mancao. The trial court denied the motion, ruling that the discharge of accused persons must comply with Section 17, Rule 119 of the Revised Rules of Criminal Procedure, which requires a hearing and proof of certain conditions.

The Court of Appeals reversed, and the Supreme Court affirmed with a modification.

The Two Competing Rules

Section 14, Rule 110 governs amendments to an information before the accused enters a plea. It provides that an amendment before plea which excludes any accused may be made only upon motion by the prosecutor, with notice to the offended party, and with leave of court.

Section 17, Rule 119, on the other hand, governs the discharge of an accused to be a state witness during trial. It requires the prosecution to present evidence and the sworn statement of each proposed state witness at a hearing, and the court must be satisfied that, among others, there is absolute necessity for the testimony, no other direct evidence is available, and the accused does not appear to be the most guilty.

The Court’s Ruling

The Supreme Court held that when an amendment excluding an accused is made before plea, Section 14, Rule 110 applies—not Section 17, Rule 119. The Court reasoned that the determination of who should be criminally charged is essentially an executive function, not a judicial one. The prosecutor enjoys wide discretion in deciding whether, what, and whom to charge.

However, this discretion is not boundless. Citing Crespo v. Mogul, the Court emphasized that once a case is filed in court, any disposition by the prosecutor must be addressed for the consideration of the court. The trial court’s action must not impair the substantial rights of the accused or the People’s right to due process.

The Court found that the trial court erred in denying the motion solely because it believed Section 17, Rule 119 applied. The trial court had granted the prosecution’s motion for reinvestigation, which effectively constituted leave of court to amend the information. The Court also clarified that a law enforcement officer like Dumlao, though disqualified from the Witness Protection Program under Republic Act No. 6981, may still be discharged as a state witness—admission to the program and discharge from an information are two different things.

Practical Takeaways

• Prosecutors may exclude an accused from an information before arraignment under Section 14, Rule 110, subject to the requirements of a motion, notice to the offended party, and leave of court.
• The stricter requirements of Section 17, Rule 119—including a hearing and proof of necessity—apply only when the accused remains in the information and discharge is sought during trial.
• A trial court’s grant of a motion for reinvestigation may be treated as leave of court to amend the information based on the reinvestigation’s results.
• Judicial discretion in these matters is limited: courts may deny an amendment only to protect substantial rights or due process, not to substitute their judgment for the prosecutor’s.
• Disqualification from the Witness Protection Program does not bar an accused from being discharged as a state witness.
