(i)any tax liability to which that person is or may be subject, or
(ii)the amount of any such liability, or
(b)to provide him with such information as he may reasonably require as being relevant to, or to the amount of, any such liability.
(2)An “authorised officer of the Board” means an officer of the Board authorised for the purposes of this Part of this Schedule.
(3)Before a person is given a notice under this paragraph he must be given a reasonable opportunity to deliver the documents or provide the information in question.
No application for consent under paragraph 2 shall be made unless he has been given that opportunity.

(3)A Commissioner who has given such consent shall not take part in, or be present at, any proceedings on, or related to, any appeal brought by the person to whom the notice applies if the Commissioner has reason to believe that any of the required information is likely to be adduced in evidence in those proceedings.
The “required information” means any document or information that was the subject of the notice with respect to which the Commissioner gave his consent.
3(1)A notice under paragraph 1 must—
(a)specify or describe the documents or information to which it relates, and

(b)that the General or Special Commissioner giving consent under paragraph 2 directs need not be disclosed.
(3)A Commissioner shall not give any such direction unless he is satisfied that the officer has reasonable grounds for believing that disclosure of the information in question would prejudice the assessment or collection of tax.
