2018 Political Law, Q20

Andreas and Aristotle are foreign nationals working with the Asian Development Bank (ADS) in its headquarters in Manila. Both were charged with criminal acts before the local trial courts.
Andreas was caught importing illegal drugs into the country as part of his “personal effects” and was thus charged with violation of Comprehensive Dangerous Drugs Act of 2002. Before the criminal proceedings could commence, the President had him deported as an undesirable alien. Aristotle was charged with grave oral defamation for uttering defamatory words against a colleague at work. In his defense, Aristotle claimed diplomatic immunity. He presented as proof a communication from the Department of Foreign Affairs stating that, pursuant to the Agreement between the Philippine Government and the ADS, the bank’s officers and staff are immune from legal processes with respect to acts performed by them in their official capacity.
(a) Can the President’s act of deporting an undesirable alien be subject to judicial review? (2.5%)
(b) Is Aristotle’s claim of diplomatic immunity proper? (2.5%)

1. Judicial Review Power
Under Article VIII, Section 1 of the 1987 Constitution, judicial power includes the duty of the courts to determine whether there has been a grave abuse of discretion amounting to lack or excess of jurisdiction on the part of any branch or instrumentality of the Government. Although the deportation of undesirable aliens is a recognized executive prerogative, executive power is not absolute. The President's exercise of deportation power remains subject to judicial review to ensure that constitutional due process guarantees are strictly observed and that executive actions do not exceed statutory or constitutional boundaries.

2. Functional Immunity Principle
Under international law and bilateral headquarters agreements, officers and staff of international organizations such as the Asian Development Bank enjoy functional immunity rather than diplomatic immunity. Functional immunity protects international officials exclusively with respect to acts performed by them in their official capacity. When an officer commits an act outside the scope of official duties, such as uttering defamatory statements against a co-worker, the act constitutes an ultra vires personal tort. Consequently, functional immunity cannot be invoked to shield the officer from local criminal prosecution for grave oral defamation.

3. Executive Deportation Authority
The power to deport aliens is an inherent act of state arising from sovereignty and self-preservation. While the President exercises broad executive discretion in determining whether an alien's presence is inimical to national interest, this authority must be exercised in accordance with established law. An alien facing deportation is entitled to administrative due process, including notice and a fair hearing before a competent tribunal. When deportation proceedings bypass constitutional safeguards or involve grave abuse of authority, the aggrieved alien may invoke judicial review before the courts to seek appropriate legal redress.
