law: 5. 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 by order in writing the registration and communicate the order to the principal employer:
  Provided that where the registering officer considers it necessary so to do for any special reasons, he may, pending such revocation, by order suspend the operation of the certificate of registration for such period as may be specified in the order and serve, by registered post, such order along with a statement of the reasons on the principal employer and such order shall take effect on the date on which such service is effected.
