1987 Constitution of the Republic of the Philippines

The President shall notify the Congress of every contract entered into in accordance with this provision, within thirty days from its execution. SECTION 3. Lands of the public domain are classified into agricultural, forest or timber, mineral lands, and national parks. Agricultural lands of the public domain may be further classified by law according to the uses which they may be devoted. Alienable lands of the public domain shall be limited to agricultural lands. Private corporations or associations may not hold such alienable lands of the public domain except by lease, for a period not exceeding twenty-five years, renewable for not more than twenty-five years, and not to exceed one thousand hectares in area. Citizens of the Philippines may lease not more than five hundred hectares, or acquire not more than twelve hectares thereof by purchase, homestead, or grant. Taking into account the requirements of conservation, ecology, and development, and subject to the requirements of agrarian reform, the Congress shall determine, by law, the size of lands of the public domain which may be acquired, developed, held, or leased and the conditions therefor. SECTION 4. The Congress shall, as soon as possible, determine by law the specific limits of forest lands and national parks, marking clearly their boundaries on the ground. Thereafter, such forest lands and national parks shall be conserved and may not be increased nor diminished, except by law. The Congress shall provide, for such period as it may determine, measures to prohibit logging in endangered forests and watershed areas. SECTION 5. The State, subject to the provisions of this Constitution and national development policies and programs, shall protect the rights of indigenous cultural communities to their ancestral lands to ensure their economic, social, and cultural well-being. The Congress may provide for the applicability of customary laws governing property rights or relations in determining the ownership and extent of ancestral domain. SECTION 6. The use of property bears a social function, and all economic agents shall contribute to the common good. Individuals and private groups, including corporations, cooperatives, and similar collective organizations, shall have the right to own, establish, and operate economic enterprises, subject to the duty of the State to promote distributive justice and to intervene when the common good so demands. SECTION 7. Save in cases of hereditary succession, no private lands shall be transferred or conveyed except to individuals, corporations, or associations qualified to acquire or hold lands of the public domain. SECTION 8. Notwithstanding the provisions of Section 7 of this Article, a natural-born citizen of the Philippines who has lost his Philippine citizenship may be a transferee of private lands, subject to limitations provided by law. SECTION 9. The Congress may establish an independent economic and planning agency headed by the President, which shall, after consultations with the appropriate public agencies, various private sectors, and local government units, recommend to Congress, and implement continuing integrated and coordinated programs and policies for national development. Until the Congress provides otherwise, the National Economic and Development Authority shall function as the independent planning agency of the government. SECTION 10. The Congress shall, upon recommendation of the economic and planning agency, when the national interest dictates, reserve to citizens of the Philippines or to corporations or associations at least sixty per centum of whose capital is owned by such citizens, or such higher percentage as Congress may prescribe, certain areas of investments. The Congress shall enact measures that will encourage the formation and operation of enterprises whose capital is wholly owned by Filipinos. In the grant of rights, privileges, and concessions covering the national economy and patrimony, the State shall give preference to qualified Filipinos. The State shall regulate and exercise authority over foreign investments within its national jurisdiction and in accordance with its national goals and priorities. SECTION 11. No franchise, certificate, or any other form of authorization for the operation of a public utility shall be granted except to citizens of the Philippines or to corporations or associations organized under the laws of the Philippines at least sixty per centum of whose capital is owned by such citizens, nor shall such franchise, certificate, or authorization be exclusive in character or for a longer period than fifty years. Neither shall any such franchise or right be granted except under the condition that it shall be subject to amendment, alteration, or repeal by the Congress when the common good so requires. The State shall encourage equity participation in public utilities by the general public. The participation of foreign investors in the governing body of any public utility enterprise shall be limited to their proportionate share in its capital, and all the executive and managing officers of such corporation or association must be citizens of the Philippines. SECTION 12. The State shall promote the preferential use of Filipino labor, domestic materials and locally produced goods, and adopt measures that help make them competitive. SECTION 13. The State shall pursue a trade policy that serves the general welfare and utilizes all forms and arrangements of exchange on the basis of equality and reciprocity. SECTION 14. The sustained development of a reservoir of national talents consisting of Filipino scientists, entrepreneurs, professionals, managers, high-level technical manpower and skilled workers and craftsmen in all fields shall be promoted by the State. The State shall encourage appropriate technology and regulate its transfer for the national benefit. The practice of all professions in the Philippines shall be limited to Filipino citizens, save in cases prescribed by law. SECTION 15. The Congress shall create an agency to promote the viability and growth of cooperatives as instruments for social justice and economic development. SECTION 16. The Congress shall not, except by general law, provide for the formation, organization, or regulation of private corporations. Government-owned or controlled corporations may be created or established by special charters in the interest of the common good and subject to the test of economic viability. SECTION 17. In times of national emergency, when the public interest so requires, the State may, during the emergency and under reasonable terms prescribed by it, temporarily take over or direct the operation of any privately owned public utility or business affected with public interest. SECTION 18. The State may, in the interest of national welfare or defense, establish and operate vital industries and, upon payment of just compensation, transfer to public ownership utilities and other private enterprises to be operated by the Government.
