"concept of sovereignty as auto-limitation."

UN Charter and Other Treaties
Limit Sovereignty

Thus, when the Philippines joined the United Nations as one of its 51 charter members, it consented to restrict its sovereign rights under the "concept of sovereignty as auto-limitation."47-A Under Article 2 of the UN Charter, "(a)ll members shall give the United Nations every assistance in any action it takes in accordance with the present Charter, and shall refrain from giving assistance to any state against which the United Nations is taking preventive or enforcement action." Such assistance includes payment of its corresponding share not merely in administrative expenses but also in expenditures for the peace-keeping operations of the organization. In its advisory opinion of July 20, 1961, the International Court of Justice held that money used by the United Nations Emergency Force in the Middle East and in the Congo were "expenses of the United Nations" under Article 17, paragraph 2, of the UN Charter. Hence, all its members must bear their corresponding share in such expenses. In this sense, the Philippine Congress is restricted in its power to appropriate. It is compelled to appropriate funds whether it agrees with such peace-keeping expenses or not. So too, under Article 105 of the said Charter, the UN and its representatives enjoy diplomatic privileges and immunities, thereby limiting again the exercise of sovereignty of members within their own territory. Another example: although "sovereign equality" and "domestic jurisdiction" of all members are set forth as underlying principles in the UN Charter, such provisos are however subject to enforcement measures decided by the Security Council for the maintenance of international peace and security under Chapter VII of the Charter. A final example: under Article 103, "(i)n the event of a conflict between the obligations of the Members of the United Nations under the present Charter and their obligations under any other international agreement, their obligation under the present charter shall prevail," thus unquestionably denying the Philippines — as a member — the sovereign power to make a choice as to which of conflicting obligations, if any, to honor.

The point is that, as shown by the foregoing treaties, a portion of sovereignty may be waived without violating the Constitution, based on the rationale that the Philippines "adopts the generally accepted principles of international law as part of the law of the land and adheres to the policy of . . . cooperation and amity with all nations."
