Section 9
SEC. 9. The grantees shall not commence any construction whatever pursuant to this franchise without first obtaining a certificate of convenience and public necessity from the Public Service Commission of the form and character provided for in Commonwealth Act Numbered One hundred and forty-six, as amended, specifically authorizing such construction. The grantees shall not exercise any right or privilege under this franchise without first having obtained such certificate of public convenience and necessity from the Public Service Commission. The Public Service Commission shall have the power to issue such certificate of convenience and public necessity whenever it shall, after due hearing, determine that such construction or such exercise of the rights and privileges under this franchise is necessary and proper for public convenience, and the Commission shall have the power in issuing such certificate to impose such conditions as to construction, equipment, maintenance, service or operation as the public convenience and interests may reasonably require, and such certificate shall state the date in which the grantees shall commence construction and the period within which the work shall be completed. In order to avail itself of the right granted by such certificate of convenience and public necessity, the grantees shall file with the Public Service Commission, within such period as said Commission shall fix, their written acceptance of the terms and conditions of this franchise and of the certificate, together with the document evidencing the fact that the deposit required in Section ten has been made. In the event that the grantees shall not commence the telephone service referred to in the certificate obtained and filed as herein provided within such period as the Public Service Commission shall have fixed, said Commission may declare said certificate null and void and the deposit made pursuant to Section ten of this Act forfeited to the National Government unless the grantees shall have been prevented from doing so by fortuitous cause or force majeure, usurped or military power, martial law, riot, uprising or other inevitable cause: Provided, however, That if the grantees shall have been prevented by any of said causes from commencing the telephone service within the period specified, the time during which they shall have been so prevented shall be added to said period: Provided, further, That failure on the part of the grantees to accept conditions of this franchise and those imposed in the certificate of convenience and public necessity shall automatically void this franchise.
