(1) The person to whom a duplicate or new security has been issued under the regulations made by the Board shall be deemed for the purposes of sub-section (2) to have been recognised by the Board as the holder of the security; and a duplicate security or a new security so issued to any person shall be deemed to constitute a new contract between the Board and such person and all persons deriving title thereafter through him.
    (2) No recognition by the Board of a person as the holder of a port security shall be called in question by any court so far as such recognition affects the relations of the Board with the person recognised by it as the holder of a port security or with any person claiming an interest in such security; and any such recognition by the Board of any person shall operate to confer on that person a title to the security or securities subject only to a personal liability to the rightful owner of the security for money had and received on his account.
