(1) Any certificate of survey granted under this Part may be cancelled or suspended by the Central Government if it has reason to believe--
         (a) that the declaration by the surveyor of the sufficiency of the hull, boilers, engines or any of the equipment of the ship has been fraudulently or erroneously made; or
         (b) that the certificate has otherwise been issued upon false of erroneous information.
     (2) Before any certificate of survey is cancelled or suspended under sub-section (1), the holder of the certificate shall be given a reasonable opportunity of showing cause why the certificate should not be cancelled or suspended, as the case may be:
     Provided that this sub-section shall not apply where the Central Government is satisfied that for some reason to be recorded in writing it is not reasonably practicable to give to the holder of the certificate an opportunity of showing cause.
