In all cases where a legal opinion is required under the GEM Listing Rules (or is otherwise obtained by the issuer) in connection with the title to a property, such opinion together, so far as practicable, with copies of any document referred to therein should be made available to the valuer carrying out any valuation in respect of the property, prior to the completion of the valuation report, and the valuer shall explain whether and if so how he has taken account of the content of such opinion in the valuation of the property.
