Defining Probable Cause in Philippine Plunder Cases: Estrada v. Office of the Ombudsman

In July 2018, the Supreme Court En Banc issued a significant ruling in Estrada v. Office of the Ombudsman (G.R. Nos. 212761-62, 213473-74, and 213538-39), consolidating petitions filed by Senator Jinggoy Ejercito Estrada, Janet Lim Napoles, and John Raymund de Asis. The case arose from the Priority Development Assistance Fund (PDAF) scam, where public funds were allegedly diverted to fake NGOs. The decision clarifies the legal standard for probable cause in plunder cases and reaffirms the courts' limited role in reviewing the Ombudsman's findings.

The Facts of the Case

The petitioners were charged with plunder under Section 2 of Republic Act No. 7080, as amended, and violation of Section 3(e) of RA 3019. The charges stemmed from the alleged illegal use of Senator Estrada's PDAF allocations from 2004 to 2012. According to the complaints filed by the National Bureau of Investigation and the Ombudsman's Field Investigation Office, Estrada endorsed fraudulent NGOs controlled by Napoles to implement ghost projects, receiving commissions and kickbacks totaling PHP 183,793,750.00.

The alleged scheme involved a systematic process: Napoles would negotiate with legislators, prepare project listings, and arrange for the release of funds through implementing agencies. Estrada's staff, including his deputy chief-of-staff, facilitated the endorsements. De Asis, described as a driver and messenger for Napoles, allegedly served as president of one of the fake NGOs and helped process the fraudulent transactions.

The Issue Presented

The sole issue before the Court was whether the Ombudsman committed grave abuse of discretion in finding probable cause to indict the petitioners for plunder and violation of Section 3(e) of RA 3019.

The Ruling: Deference to the Ombudsman

The Supreme Court denied the petitions and upheld the Ombudsman's findings. The Court emphasized that both the Constitution and RA 6770 (The Ombudsman Act of 1989) grant the Ombudsman wide latitude in investigating criminal complaints against public officials. As an independent constitutional body, the Ombudsman is better positioned to assess the strengths and weaknesses of evidence in determining probable cause.

The Court reiterated its policy of non-interference in the Ombudsman's probable cause determinations. This policy rests on respect for the Ombudsman's constitutional powers and practical considerations—otherwise, courts would be swamped with petitions seeking dismissal of investigations. However, the Court clarified that it may review the Ombudsman's action when there is a charge of grave abuse of discretion, which implies a capricious and whimsical exercise of judgment tantamount to lack of jurisdiction.

Understanding Probable Cause

The decision distinguishes between two types of probable cause: executive and judicial. The executive determination occurs during preliminary investigation and belongs to the public prosecutor. The judicial determination is made by a judge to decide whether to issue a warrant of arrest.

Under Rule 112 of the Revised Rules of Criminal Procedure, probable cause exists when there are sufficient grounds to engender a well-founded belief that a crime has been committed and the respondent is probably guilty. The Court quoted its earlier ruling in Estrada v. Office of the Ombudsman: probable cause requires more than bare suspicion but less than evidence that would justify conviction. It is based on opinion and reasonable belief, not on the technical calibrations of the rules of evidence.

Significantly, the Court held that probable cause can be established with hearsay evidence, as long as there is substantial basis for crediting the hearsay. Preliminary investigation is not the occasion for a full and exhaustive display of the prosecution's evidence, and technical rules of evidence should not be applied at that stage.

Application to the Plunder Charges

Applying these principles, the Court found that the Ombudsman properly determined probable cause. The elements of plunder were reasonably apparent: Estrada was a public officer; he allegedly amassed ill-gotten wealth through a series of overt acts; and the aggregate amount exceeded PHP 50 million. The evidence included witness testimonies, ledgers showing kickback payments, endorsement letters, and corroborating statements from implementing agency officials.

Similarly, the elements of violation of Section 3(e) of RA 3019 were present: the accused acted with manifest partiality and evident bad faith, causing undue injury to the government and giving unwarranted benefits to private parties.

Practical Takeaways

• Probable cause is a low threshold. It requires only a reasonable belief of guilt, not proof beyond reasonable doubt. This standard applies even in serious cases like plunder.
• Courts generally defer to the Ombudsman. The Ombudsman's findings on probable cause are respected unless there is clear evidence of grave abuse of discretion.
• Hearsay can establish probable cause. At the preliminary investigation stage, hearsay evidence may suffice if there is substantial basis for crediting it.
• Defenses are for trial. The validity of a defense, the admissibility of evidence, and the credibility of witnesses are matters for the trial court, not the preliminary investigation.
• Plunder requires a pattern. The prosecution must show a combination or series of overt acts resulting in ill-gotten wealth of at least PHP 50 million, but this need only be reasonably apparent at the probable cause stage.
