Political Law · Environmental writs
The Supreme Court held that suits against US Navy officers for the USS Guardian's grounding on Tubbataha Reefs are barred by State immunity, though the US bears international responsibility under UNCLOS Article 31.
The USS Guardian, a US Navy minesweeper granted diplomatic clearance to visit Philippine ports, ran aground on the South Shoal of the Tubbataha Reefs Natural Park on January 17, 2013 while transiting the Sulu Sea, damaging the protected coral reef system. Salvage operations were completed by March 30, 2013. Petitioners, citizens and organizations suing also for minors and generations yet unborn, filed a petition for a Writ of Kalikasan with a prayer for a TEPO against US Navy officials and Philippine officials, and also sought to nullify provisions of the Visiting Forces Agreement.
Whether the Court may exercise jurisdiction over the US respondents, or whether the suit is barred by State immunity
The Court held it has no jurisdiction over the US respondents. They were sued in their official capacity as commanding officers of the US Navy who had control and supervision over the USS Guardian and its crew, and the acts complained of were committed while performing official military duties. Since satisfaction of any judgment would require remedial action and appropriation of funds by the US government, the suit is in effect one against the United States itself, and the principle of State immunity bars the exercise of jurisdiction over respondents Swift, Rice and Robling.
Whether petitioners have legal standing to file the petition for a Writ of Kalikasan
Yes. Following Oposa v. Factoran, the right to a balanced and healthful ecology is a public right of transcendental importance with intergenerational implications, so ordinary citizens may sue for its enforcement, even in representation of future generations. This liberalized standing is now enshrined in the citizen suit provision of the Rules of Procedure for Environmental Cases, which collapses the traditional rule on personal and direct interest on the principle that humans are stewards of nature.
Whether the United States, a non-party to UNCLOS, bears responsibility for the damage caused by its warship in Philippine waters
The Court concurred with Justice Carpio that non-membership in UNCLOS does not mean the US will disregard Philippine rights as a Coastal State over its internal waters and territorial sea, since the US as a matter of long-standing policy considers itself bound by customary rules on the traditional uses of the oceans. While warships enjoy sovereign immunity from the jurisdiction of Coastal States, Articles 30 and 31 create exceptions: a non-complying warship may be required to leave, and the flag State bears international responsibility for loss or damage resulting from non-compliance with the Coastal State's laws. The Court thus expects the US to bear international responsibility for the Tubbataha grounding, but this responsibility is to be pursued through diplomatic and executive channels, not by suit here.
Suits against foreign State officials for acts done in the performance of official (jure imperii) functions are in effect suits against the foreign State, which cannot be impleaded without its consent; redress for such acts lies in international responsibility of the flag State pursued through diplomatic channels, not in local courts.
