Section 2
SEC. 2. At least twenty days immediately prior to the day of the election, the certificates of candidacy for said election, in quadruplicate, subscribed and sworn to by the candidates themselves, shall be filed with the Commission on Elections which shall immediately send copies of said certificates of candidacy to the Secretary of the House of Representatives, and to the provincial treasurers of the provinces where the special elections shall be held who in turn must send immediately said copies to the boards of election inspectors concerned. The Commission on Elections, upon receipt of said certificates of candidacy, shall communicate the names of said candidates by telegram or radiogram to the corresponding provincial treasurer who in turn must transmit the same immediately to the boards of election inspectors of the legislative district where the election will be held. If the certificate of candidacy is sent by mail, it shall be by registered mail, and the date on which the envelope containing the certificate was deposited in the post office may be considered as the filing date of such certificate of candidacy. However, in case the post office wherein this envelope was deposited does not have registered mail facilities, the postmaster shall accept said envelope as ordinary mail, show the date on which it was deposited on the envelope, and in addition swear to a statement showing that he had received the said envelope on the same date, which date shall be considered as the filing date of such certificate of candidacy. In the absence of a postmaster, the duties pertaining to him shall be performed by the municipal treasurer. A person occupying any civil office by appointment in the Government or any of its political subdivisions or agencies or government-owned or controlled corporations, whether such office be appointive or elective, shall be considered to have resigned from such office from the moment of the filing of his certificate of candidacy.
