Any of the following reasons shall be sufficient for denial of the certificate:
(A) That the application is not in the form, and does not contain the information required to be contained therein by this chapter.
(B) That the vehicles described therein are inadequate or unsafe for the purposes for which they are to be used.
(C) That the color scheme, name, monogram, or insignia to be used upon such automobiles would be in conflict with or imitate any other certificate.
(D) That the location of the stand, as requested would congest or interfere with travel on any public street, or that the proposed stand is within 300 feet of any other taxi stand theretofore fixed by the City Council on the same street.
(E) That the City Council finds that there are a sufficient number of taxicabs and automobiles for hire in the city to fully serve the public and that the granting of more certificates would unduly congest the traffic and interfere with the free use of the public streets by the public, and that the public interest, convenience and necessity do not require the issuance of the certificate.
