(1) Notwithstanding anything contained in sub-rules (1), (3) and (7) of rule 6, and sub-rule (5) of rule 9, any information which is by nature confidential or which is provided on a confidential basis shall, upon cause being shown, be treated as such by the Authorised Officer and not be disclosed without specific authorisation of the party providing such information.
(2) The Authorised Officer may require the parties providing information on confidential basis to furnish non confidential summary thereof and if, in the opinion of the party providing such information, such information cannot be summarised, such party may submit to the Authorised Officer a statement of reasons why summarisation of such information is not possible.
(3) Notwithstanding anything contained in sub-rule (2), if the Authorised Officer is satisfied that the request for confidentiality is not warranted or the supplier of the information is unwilling either to make the information public or to authorise its disclosure in a generalised or summary form, it may disregard such information unless it is demonstrated to its satisfaction from appropriate sources that such information is correct.
