Lasco vs. United Nations Revolving Fund for Natural Resources Exploration

Factual Background

The petitioners were employees of UNRFNRE, a special fund and subsidiary organ of the United Nations engaged in a joint project with the Philippine Government for mineral exploration in Dinagat Island. The petitioners were dismissed from employment and filed complaints before the Labor Arbiter for illegal dismissal and damages, docketed as NLRC Cases Nos. SRAB 10-03-00067-91 to 10-03-00078-91 and SRAB 10-07-00159-91. UNRFNRE moved to dismiss the complaints on the ground of diplomatic immunity under the 1946 Convention on the Privileges and Immunities of the United Nations, and submitted a letter from the Department of Foreign Affairs dated August 26, 1991 acknowledging its immunity.

Trial Court and NLRC Proceedings

On November 25, 1991, the Labor Arbiter dismissed the complaints on the ground that UNRFNRE enjoyed diplomatic immunity, relying on a Department of Foreign Affairs letter dated September 10, 1991. The petitioners’ motion for reconsideration before the Labor Arbiter was denied. The petitioners appealed to the NLRC, which affirmed the dismissal in its Resolution dated January 25, 1993. Petitioner then sought relief by filing a petition for certiorari under Rule 65, Rules of Court in the Supreme Court.

Petition for Certiorari and Preliminary Procedural Issue

The petition invoked certiorari under Rule 65 to annul the NLRC resolution. The Court observed that pursuant to Article 223 of the Labor Code, decisions of the NLRC are final and executory and ordinarily may be assailed only by certiorari; however, the Court reiterated the settled rule that an aggrieved party must first file a motion for reconsideration before the tribunal as a condition precedent to certiorari (cf. Liberty Insurance Corporation v. Court of Appeals, 222 SCRA 37). The petitioners failed to file a motion for reconsideration of the NLRC resolution and offered no explanation for that omission. The Court nonetheless gave due course to the petition because of the international implications of the issues raised.

Parties' Contentions

The petitioners contended that acts of mining exploration and exploitation fall outside the official functions of an international agency protected by diplomatic immunity and that UNRFNRE waived any immunity by engaging in exploration work and by entering into employment contracts. The petitioners further invoked the constitutional duty of the State to protect labor and promote full employment and equality of employment opportunities (1987 Constitution, Art. XIII, Sec. 3). The Office of the Solicitor General and UNRFNRE maintained that the organization was covered by diplomatic immunity as a specialized agency of the United Nations, that such immunity was recognized by the Executive through the Department of Foreign Affairs, and that no express waiver of immunity had been made.

Legal Issues Presented

The principal issues were whether UNRFNRE, as a specialized agency of the United Nations, was entitled to diplomatic immunity in the Philippines; whether such immunity extended to acts alleged by petitioners, including employment relations arising from exploration activities; whether the Executive’s recognition of immunity is conclusive upon the courts; and whether a waiver of immunity may be inferred from UNRFNRE’s activities in the Philippines.

The Court’s Ruling

The Court dismissed the petition. It held that the diplomatic immunity of UNRFNRE had been sufficiently established by the Department of Foreign Affairs’ recognition and confirmation of that immunity in accordance with the 1946 Convention on the Privileges and Immunities of the United Nations, to which the Philippines was a party. The Court ruled that the determination whether an international organization is entitled to diplomatic immunity is a political question and that the Executive’s recognition of such immunity is conclusive on the courts and quasi-judicial agencies. The Court further held that no express waiver of immunity by UNRFNRE had been shown.

Legal Basis and Reasoning

The Court anchored its reasoning on Article 105 of the Charter of the United Nations, which confers privileges and immunities necessary for the Organization’s fulfillment of its purposes, and on the Convention on the Privileges and Immunities of the Specialized Agencies, particularly Art. III, Sec. 4 (immunity from legal process unless expressly waived, with no waiver extending to measures of execution) and Sec. 5 (inviolability and immunity of premises, property, and assets). The Court invoked the constitutional policy that the Philippines adopts generally accepted principles of international law (1987 Constitution, Art. II, Sec. 2) and noted that both the Charter and the Convention have the force and effect of law. The Court relied on prior precedents, including World Health Organization v. Aquino, where it recognized that diplomatic immunity is essentially a political question and that courts must follow the Executive’s determination to avoid embarrassing the political branch in foreign relations. The Court observed that the purpose of immunity is to secure the legal and practical independence of international organizations and to ensure unimpeded performance of their functions, citing authorities including Jenks and International Catholic Migration Commission v. Calleja. The Court rejected the characterization of UNRFNRE’s presence as a commercial venture, noting that its mission in the joint project was not pecuniary exploitation of resources but assistance to improve the quality of life of the people.

Relief and Alternative Remedies

Although denying judicial jurisdiction with respect to the petitioners’ labor complaints, the Court recognized that petitioners were not left without remedy. It noted Art. I
