Navigating Libel Law: Probable Cause and Privileged Communication in the Philippines

A Supreme Court ruling clarifies that probable cause for libel is a prosecutor's call, and privileged communication is a trial defense.


The Supreme Court’s 2010 decision in Corpuz v. Del Rosario (G.R. No. 149261) clarifies two important points for anyone facing a libel complaint: who decides whether a case should go to trial, and when a defense of privileged communication can be raised. The ruling underscores that a finding of probable cause rests with the public prosecutor, and that courts will respect that finding unless there is clear grave abuse of discretion.

The Facts of the Case

The case began with an affidavit-complaint filed by Assistant Solicitor General Roman G. Del Rosario against his colleague, Assistant Solicitor General Azucena B. Corpuz. Del Rosario alleged that a memorandum Corpuz issued on June 13, 1997 contained a defamatory statement about him. The memorandum, addressed to the Solicitor General and all Assistant Solicitors General, included the phrase that "there is no such thing as 'palabra de honor' as far as ASG del Rosario is concerned."

After preliminary investigation, the investigating prosecutor found probable cause for libel. The prosecutor reasoned that the statement imputed a defect on Del Rosario that tended to discredit his integrity as a government lawyer. Because the memorandum was distributed beyond the Solicitor General to all Assistant Solicitors General, the prosecutor also found that malice was presumed and that there was undue publication.

The Issue Before the Court

Corpuz appealed the finding of probable cause all the way to the Supreme Court. She argued that the prosecutor committed grave abuse of discretion because the elements of libel were not sufficiently established. She also claimed that her memorandum was a privileged communication — a private communication made in the performance of a legal, moral, or social duty — and therefore should not be considered libelous.

The Ruling: Probable Cause Is the Prosecutor’s Call

The Supreme Court denied the petition and affirmed the lower courts’ rulings. The Court reiterated a well-settled rule: the determination of probable cause for filing an information in court is an executive function that belongs to the public prosecutor and, ultimately, to the Secretary of Justice. Judicial review of the prosecutor’s resolution is limited to determining whether there was grave abuse of discretion amounting to lack or excess of jurisdiction.

The Court defined probable cause as "such facts as are sufficient to engender a well-founded belief that a crime has been committed and that respondent is probably guilty thereof." A finding of probable cause does not require clear and convincing evidence of guilt, nor evidence establishing guilt beyond reasonable doubt. It only requires evidence showing that more likely than not a crime was committed by the suspect.

The Court found that the prosecutor’s resolution squarely addressed the elements of libel under the Revised Penal Code: (1) an imputation of a crime, vice, or defect; (2) that the imputation is malicious; (3) that it is given publicity; and (4) that the victim is identifiable. Since these elements were established during the preliminary investigation, the prosecutor had a well-founded belief that libel was committed.

Privileged Communication Is a Trial Defense

Corpuz also argued that her memorandum was a privileged communication under the exception in the Revised Penal Code for a private communication made by any person to another in the performance of any legal, moral, or social duty.

The Court rejected this argument at the preliminary investigation stage. It held that whether the memorandum was a privileged communication is essentially evidentiary in nature and a matter of defense. This defense must be presented and heard during trial, where the accused can prove innocence through a full examination of the evidence. The Court stressed that it is not a trier of facts and cannot assess the merit of such a claim during a review of probable cause.

Practical Takeaways

  • Probable cause is a low threshold. A prosecutor only needs a well-founded belief that a crime was committed and that the suspect is probably guilty. It does not require proof beyond reasonable doubt.
  • Courts defer to prosecutors. Judges will not second-guess a prosecutor’s finding of probable cause unless there is a clear showing of grave abuse of discretion — such as arbitrary, capricious, or whimsical exercise of power.
  • Privileged communication is a defense for trial. Arguments that a statement is privileged or made without malice are matters of defense. They are best raised during the trial itself, not during the preliminary investigation.
  • Publication matters. A memorandum addressed to multiple people can constitute publication for purposes of libel, even if it is an internal office document.
  • An accusation is not guilt. A finding of probable cause merely means the case should proceed to trial. The accused still has the opportunity to prove innocence.
