The sub-panel may invite—
any person to whom notice under paragraph 28 was given, or
the designated HMRC officer,
(or both) to supply the sub-panel with further information within a period specified in the invitation.
Invitations must explain the effect of sub-paragraph (4) or (5) (as appropriate).
If a person invited under sub-paragraph (2)(a) supplies information to the sub-panel under this paragraph, that person must at the same time send a copy of the information to the designated HMRC officer.
If a designated HMRC officer supplies information to the sub-panel under this paragraph, the officer must at the same time send a copy of the information to each person to whom notice under paragraph 28 was given.
