Section 2
SEC. 2. Section fifteen, paragraph (i), of Act Numbered Thirty-one hundred and eight is hereby amended to read as follows: "(i) With the exception of public services for the operation of vessels within the Philippine Islands, no public service as herein defined shall operate in the Philippine Islands without having first secured from the Commission a certificate, which shall be known as Certificate of Public Convenience, to the effect that the operation of said public service and the authorization to do business will promote the public interests in a proper and suitable manner. Every public service existing on the date of the approval of this Act shall pay the fees herein prescribed for the issuance of the proper certificate of public convenience or public necessity and convenience, as the case may be, in the same manner as said fees shall be payable by any new-public service subject to the provisions of this Act, within sixty days from the date of the approval of this Act: Provided, however, That in the case of a public service for the operation of whose business it is necessary to obtain a franchise from either a municipal government, or a provincial government, under the provisions of Act Numbered Six hundred and sixty-seven, as amended by Act Numbered Ten hundred and twenty-two, or from the Philippine Legislature, such public service shall secure a certificate to be known as Certificate of Public Necessity and Convenience, as required by section twenty-two of this Act. The duty to secure such certificates of public convenience or certificates of public necessity and convenience by public services or to pay the fees herein prescribed by public services already existing is of a mandatory character and noncompliance herewith may, in the judgment of the Public Service Commission, be sufficient ground for the revocation and cancellation of any vested right and for the imposition of the penalty provided for in this Act."
