Ombudsman's Primary Jurisdiction: Who Investigates Public Officials First

When a complaint is filed against a public official, which government body has the authority to conduct the preliminary investigation? This question often arises when both the Office of the Ombudsman and the Department of Justice (DOJ) appear to have overlapping powers. In Department of Justice v. Liwag (G.R. No. 149311, February 11, 2005), the Supreme Court En Banc settled this issue by affirming that the Ombudsman's primary jurisdiction prevails once it has taken cognizance of a complaint involving public officials.

The Facts of the Case

The case began when Mary Ong, a former undercover agent, filed a complaint-affidavit before the Ombudsman against PNP General Panfilo Lacson, PNP Colonel Michael Ray Aquino, and other officials for various crimes. The Ombudsman found the complaint sufficient and required the respondents to file their counter-affidavits.

Months later, Ong and other witnesses executed sworn statements before the National Bureau of Investigation (NBI) alleging the same facts. The NBI recommended investigating the same respondents for kidnapping for ransom and murder. The DOJ then issued subpoenas and scheduled a preliminary investigation.

Lacson and Aquino moved to dismiss the DOJ proceedings, arguing that the Ombudsman has primary jurisdiction over cases involving public officials. When the DOJ denied their motion, they filed a petition for prohibition before the Regional Trial Court (RTC), which ruled in their favor and enjoined the DOJ from proceeding. The DOJ elevated the matter to the Supreme Court.

The Central Issue

The core question was whether the DOJ could conduct a preliminary investigation despite the pendency before the Ombudsman of a complaint involving the same accused, facts, and circumstances.

The Ruling: Ombudsman's Primary Jurisdiction Prevails

The Supreme Court dismissed the DOJ's petition and upheld the RTC's ruling. The Court held that while the DOJ has general jurisdiction to conduct preliminary investigations, this general authority cannot diminish the Ombudsman's plenary power and primary jurisdiction over complaints directed against public officers and employees.

The Court anchored its ruling on Section 15(1) of Republic Act No. 6770 (the Ombudsman Act of 1989), which grants the Ombudsman primary jurisdiction over cases cognizable by the Sandiganbayan. This provision allows the Ombudsman to take over, at any stage, the investigation of such cases from any investigatory agency of the government.

The Doctrine of First Cognizance

The Court rejected the DOJ's argument that it had concurrent jurisdiction. Even assuming concurrent jurisdiction existed, the Court applied the settled rule that the body or agency that first takes cognizance of a complaint exercises jurisdiction to the exclusion of others. Since Mary Ong filed her complaint with the Ombudsman first, that office had the authority to proceed with the preliminary investigation to the exclusion of the DOJ.

The Court distinguished prior cases relied upon by the DOJ, noting that in each of those cases, the complaint was filed solely with the DOJ or another agency—not with the Ombudsman first. None involved simultaneous exercise of power between two coordinate bodies.

Why This Matters

The Court emphasized that allowing the same complaint to be filed successively before multiple investigative bodies would promote multiplicity of proceedings, cause undue difficulty to respondents who would have to defend themselves before every agency, risk conflicting resolutions, and entail unnecessary expenditure of public funds.

Practical Takeaways

• The Ombudsman's primary jurisdiction over cases involving public officials is not merely shared with other agencies—it prevails once the Ombudsman has taken cognizance of a complaint.
• First to act wins: When two bodies may have jurisdiction, the one that first takes cognizance of the complaint exercises jurisdiction to the exclusion of the other.
• The DOJ's general authority to investigate crimes does not override the Ombudsman's constitutionally protected role in investigating public officials.
• Filing the same complaint before multiple agencies is discouraged and may be enjoined by the courts.
• The Ombudsman may delegate its investigative power, but the delegate cannot claim equal power with the Ombudsman.
