Section 11. Whenever the President transmits to the President of the Senate and the Speaker of the House of Representatives his written declaration that he is unable to discharge the powers and duties of his office, and until he transmits to them a written declaration to the contrary, such powers and duties shall be discharged by the VicePresident as Acting President. Whenever a majority of all the Members of the Cabinet transmit to the President of the Senate and to the Speaker of the House of Representatives their written declaration that the President is unable to discharge the powers and duties of his office, the VicePresident shall immediately assume the powers and duties of the office as Acting President. Thereafter, when the President transmits to the President of the Senate and to the Speaker of the House of Representatives his written declaration that no inability exists, he shall reassume the powers and duties of his office. Meanwhile, should a majority of all the Members of the Cabinet transmit within five days to the President of the Senate and to the Speaker of the House of Representatives, their written declaration that the President is unable to discharge the powers and duties of his office, the Congress shall decide the issue. For that purpose, the Congress shall convene, if it is not in session, within forty-eight hours, in accordance with its rules and without need of call. If the Congress, within ten days after receipt of the last written declaration, or, if not in session, within twelve days after it is required to assemble, determines by a two-thirds vote of both Houses, voting separately, that the President is unable to discharge the powers and duties of his office, the Vice-President shall act as President; otherwise, the President shall continue exercising the powers and duties of his office. Section 12. In case of serious illness of the President, the public shall be informed of the state of his health. The members of the Cabinet in charge of national security and foreign relations and the Chief of Staff of the Armed Forces of the Philippines, shall not be denied access to the President during such illness. Section 13. The President, Vice-President, the Members of the Cabinet, and their deputies or assistants shall not, unless otherwise provided in this Constitution, hold any other office or employment during their tenure. They shall not, during said tenure, directly or indirectly, practice any other profession, participate in any business, or be financially interested in any contract with, or in any franchise, or special privilege granted by the Government or any subdivision, agency, or instrumentality thereof, including government-owned or controlled corporations or their subsidiaries. They shall strictly avoid conflict of interest in the conduct of their office. The spouse and relatives by consanguinity or affinity within the fourth civil degree of the President shall not, during his tenure, be appointed as Members of the Constitutional Commissions, or the Office of the Ombudsman, or as Secretaries, Undersecretaries, chairmen or heads of bureaus or offices, including government-owned or controlled corporations and their subsidiaries.
