As Senator Jovito R. Salonga and Former Chief Justice Pedro L. Yap stated in their book, Public International Law (p. 83,1956 ed.):
Permanent international commissions and administrative bodies have been created by the agreement of a considerable number of States for a variety of international purposes, economic or social and mainly non-political. Among the notable instances are the International Labor Organization, the International Institute of Agriculture, the International Danube Commission. In so far as they are autonomous and beyond the control of any one State, they have a distinct juridical personality independent of the municipal law of the State where they are situated. As such, according to one leading authority they must be deemed to possess a species of international personality of their own. (Salonga and Yap, Public International Law, 83 [1956 ed.]
Pursuant to its being a signatory to the Agreement, the Republic of the Philippines agreed to be represented by one Director in governing SEAFDEC Council (Agreement Establishing SEAFDEC, Art. 5, Par. 1,. . .), and that its national laws and regulations shall apply only insofar as its contributions to SEAFDEC of "an agreed amount of money, movable and immovable property and services necessary for the establishment and operation of the Center" are concerned (Art. 11, ibid). It expressly waived the application of the Philippine laws on the disbursement of funds of petitioner SEAFDEC-AQD (Section 2, P.D. No. 292).
The then Minister of Justice likewise opined that Philippine Courts have no jurisdiction over SEAFDEC-AQD in Opinion No. 139, Series of 1984 —
4. One of the basic immunities of an international organization is immunity from local jurisdiction, i.e., that it is immune from the legal writs and processes issued by the tribunals of the country where it is found. (See Jenks, Id., pp. 37-44). The obvious reason for this is that the subjection of such an organization to the authority of the local courts would afford a convenient medium thru which the host government may interfere in their operations or even influence or control its policies and decisions of the organization; besides, such objection to local jurisdiction would impair the capacity of such body to discharge its responsibilities impartially on behalf of its member-states. In the case at bar, for instance, the entertainment by the National Labor Relations Commission of Mr. Madamba's reinstatement cases would amount to interference by the Philippine Government in the management decisions of the SEARCA governing board; even worse, it could compromise the desired impartiality of the organization since it will have to suit its actuations to the requirements of Philippine law, which may not necessarily coincide with the interests of the other member-states. It is precisely to forestall these possibilities that in cases where the extent of the immunity is specified in the enabling instruments of international organizations (jurisdictional immunity, is specified in the enabling instruments of international organizations), jurisdictional immunity from the host country is invariably among the first accorded. (See Jenks, Id.; See Bowett. The Law of International Institutions. pp. 284-285).
