G.R. No. 152318 14 of 19 http://sc.judiciary.gov.ph/jurisprudence/2009/april2009/152318.htm In Public International Law, when a state or international agency wishes to plead sovereign or diplomatic immunity in a foreign court, it requests the Foreign Office of the state where it is sued to convey to the court that said defendant is entitled to immunity. In the United States, the procedure followed is the process of "suggestion," where the foreign state or the international organization sued in an American court requests the Secretary of State to make a determination as to whether it is entitled to immunity. If the Secretary of State finds that the defendant is immune from suit, he, in turn, asks the Attorney General to submit to the court a "suggestion" that the defendant is entitled to immunity. In England, a similar procedure is followed, only the Foreign Office issues a certification to that effect instead of submitting a "suggestion" (O'Connell, I International Law 130 [1965]; Note: Immunity from Suit of Foreign Sovereign Instrumentalities and Obligations, 50 Yale Law Journal 1088 [1941]). In the Philippines, the practice is for the foreign government or the international organization to first secure an executive endorsement of its claim of sovereign or diplomatic immunity. But how the Philippine Foreign Office conveys its endorsement to the courts varies. In International Catholic Migration Commission v. Calleja, 190 SCRA 130 (1990), the Secretary of Foreign Affairs just sent a letter directly to the Secretary of Labor and Employment, informing the latter that the respondentemployer could not be sued because it enjoyed diplomatic immunity. In World Health Organization v. Aquino, 48 SCRA 242 (1972), the Secretary of Foreign Affairs sent the trial court a telegram to that effect. In Baer v. Tizon, 57 SCRA 1 (1974), the U.S. Embassy asked the Secretary of Foreign Affairs to request the Solicitor General to make, in behalf of the Commander of the United States Naval Base at Olongapo City, Zambales, a "suggestion" to respondent Judge. The Solicitor General embodied the [53] "suggestion" in a Manifestation and Memorandum as amicus curiae. It is to be recalled that the Labor Arbiter, in both of his rulings, noted that it was imperative for petitioners to secure from the Department of Foreign Affairs a certification of respondents [54] diplomatic status and entitlement to diplomatic privileges including immunity from suits. The requirement might not necessarily be imperative. However, had GTZ obtained such certification from the DFA, it would have provided factual basis for its claim of immunity that would, at the very least, establish a disputable evidentiary presumption that the foreign party is indeed immune which the opposing party will have to overcome with its own factual evidence. We do not see why GTZ could not have secured such certification or endorsement from the DFA for purposes of this case. Certainly, it would have been highly prudential for GTZ to obtain the same after the Labor Arbiter had denied the motion to dismiss. Still, even at this juncture, we do not see any evidence that the DFA, the office of the executive branch in charge of our diplomatic relations, has indeed endorsed GTZs claim of immunity. It may be possible that GTZ tried, but failed to secure such certification, due to the same concerns that we have discussed herein. Would the fact that the Solicitor General has endorsed GTZs claim of States immunity from suit before this Court sufficiently substitute for the DFA certification? Note that the rule in public international law quoted in Holy See referred to endorsement by the Foreign Office of the State where the suit is filed, such foreign office in the Philippines being the Department of Foreign Affairs. Nowhere in the Comment of the OSG is it manifested that the DFA has endorsed GTZs 1/26/2016 4:07 PM
