Liang vs. People

Factual Background

Jeffrey Liang (Huefeng) was an economist employed by the Asian Development Bank. In 1994 he was criminally charged before the MeTC of Mandaluyong City with two counts of grave oral defamation for allegedly uttering defamatory words against fellow ADB worker Joyce Cabal. The MeTC issued a warrant of arrest, arrested petitioner, and set bail at P2,400.00 for each criminal charge. The MeTC released petitioner to the custody of the Security Officer of the ADB after bail was posted.

DFA Communication and MeTC Dismissal

The day following petitioner's release, the MeTC judge received an "office of protocol" communication from the Department of Foreign Affairs stating that petitioner was covered by immunity from legal process under Section 45 of the Agreement. Acting on that communication ex parte and without notice to the prosecution, the MeTC dismissed the two criminal cases.

Prosecution's Motions and RTC Intervention

The prosecution filed a motion for reconsideration of the MeTC dismissals. The Department of Foreign Affairs opposed the motion. When the MeTC denied reconsideration, the prosecution sought relief by filing a petition for certiorari and mandamus in the RTC of Pasig City. The RTC set aside the MeTC rulings and ordered the MeTC to enforce the previously issued warrant of arrest.

Petition to the Supreme Court and Petitioner's Contentions

After denial of reconsideration in the RTC, petitioner elevated the matter to this Court by a petition for review. Petitioner argued that he enjoyed immunity under Section 45 of the Agreement and also asserted that no preliminary investigation was conducted prior to the filing of the criminal cases in court.

Supreme Court's Disposition

The Supreme Court denied the petition. The Court held that the DFA communication asserting immunity did not bind the courts and that the MeTC erred in dismissing the cases ex parte without affording the prosecution an opportunity to be heard. The Court ordered the MeTC's dismissals set aside and the warrant enforced pursuant to the RTC direction to proceed.

Legal Basis for Rejecting Automatic Recognition of Immunity

The Court reasoned that the DFA's determination that a person is covered by immunity is preliminary and not binding on the courts. The MeTC's ex parte receipt of the DFA protocol and its motu proprio dismissal deprived the prosecution of due process. The Court cited United States v. Guinto, 182 SCRA 644 (1990), for the proposition that such executive communications require judicial inquiry.

Requirement of an Evidentiary Inquiry into Official Capacity

The Court emphasized that Section 45 of the Agreement provides immunity "with respect to acts performed by them in their official capacity except when the Bank waives the immunity." The Court held that the immunity is therefore not absolute. It requires a determination whether the alleged acts were performed in an official capacity. That factual and legal determination demands an opportunity for the prosecution to present controverting evidence.

Defamation and the Limits of Official Immunity

The Court observed that the commission of a crime such as slander or defamation ordinarily cannot form part of official functions. The Court noted the settled principle that public officials may be liable in their personal capacity for acts done with malice, in bad faith, or beyond the scope of authority. The Court cited M.H. Wylie v. Rarang, 209 SCRA 357 (1992), and other authorities to support the proposition that the mere invocation of an immunity clause does not automatically result in dismissal of criminal charges, referencing Chavez v. Sandiganbayan, 193 SCRA 282 (1991).

Diplomatic Immunity and the Vienna Convention

Addressing the contention that diplomatic immunity might apply, the Court recalled that under the Vienna Convention on Diplomatic Relations a diplomatic agent enjoys immunity from criminal jurisdiction of the receiving State except for actions relating to professional or commercial activities outside official functions. The Court cited Section 31, 1(c) and Minucher v. CA, 214 SCRA 242 (1992), to underline that criminal acts are generally not within official functions and that the exception must be strictly construed.

Preliminary Investigation and MeTC Jurisdiction

On the contention that no preliminary investigation was conducted, the Court held that preliminary investigation is not an absolute right in cases cognizable by the MeTC. The Court explained that preliminary investigati
