(1) If the person entitled to a Government security applies to the Bank alleging that the Government security has been lost, stolen or destroyed, or has been defaced or mutilated, the Bank may, on proof to its satisfaction of the loss, theft, destruction, defacement or mutilation of the Government security, and subject to such conditions and on payment of such fees as may be prescribed, order the issue of a duplicate Government security to the applicant.
     (2) If the person entitled to a Government security applies to the Bank to have the Government security converted into a Government security of another form, or into a Government security issued in connection with another loan or to have it consolidated with other like Government securities, or to have it sub-divided, or to have it renewed, stripped or reconstituted, the Bank may, subject to such conditions and on payment of such fees as may be prescribed, cancel the Government security and order the issue of a new Government security or Government securities.
     Explanation.--A Government security may be stripped separately for interest and principal or reconstituted on the application of the holder subject to such terms and conditions as may be specified.
     (3) The person to whom a duplicate Government security or a new Government security is issued under this section shall be deemed for the purposes of section 18 to have been recognised by the Bank as the holder of the Government security; and a duplicate Government security or new Government security so issued to any person shall be deemed to constitute a new contract between the Government and such person and all persons deriving title thereafter through him:
     Provided that the issue of new security under this section shall not affect the interest of third parties in whose favour a charge or other interest was lawfully created and was subsisting at the time of issue of the new security.
