The President appoints Emilio Melchor as Chairperson of the CSC. Upon confirmation of Melchor's appointment, the President issues an executive order including him as Ex-Officio member of the Board of Trustees of the Government Service Insurance System (GSIS), Employees Compensation Commission (ECC), and the Board of Directors of the Philippine Health Insurance Corporation (PHILHEALTH). Allegedly, this is based on the Administrative Code of 1987 (E.O. No. 292), particularly Section 14, Chapter 3, Title I-A, Book V. This provision reads: "The chairman of the CSC shall be a member of the Board of Directors of other governing bodies of government entities whose functions affect the career development, employment, status, rights, privileges, and welfare of government officials and employees..." A taxpayer questions the designation of Melchor as ex-officio member of the said corporations before the Supreme Court based on two (2) grounds, to wit: (1) it violates the constitutional prohibition on members of the Constitutional Commissions to hold any other office or employment during his tenure; and (2) it impairs the independence of the CSC. Will the petition prosper? Explain. (2015 BAR)
