8. Revocation of registration in certain cases.- If the registering officer is satisfied, either on a reference made to him in this behalf or otherwise, that the registration of any establishment has been obtained by misrepresentation or suppression of any material fact, or that for any other reason the registration has become useless or ineffective and, therefore, requires to be revoked, the registering officer may, after giving an opportunity to the principal employer of the establishment to be heard and with the previous approval of the appropriate Government, revoke the registration.
