Article 5

Within twenty-one days of being notified under the last foregoing rule that his appeal has been referred to the tribunal, the appellant shall furnish the tribunal and the Board with a statement in writing setting out the grounds of his appeal.

If the tribunal requires any facilities or further facilities for the investigation of the appellant's case, it shall give to the appellant notice in writing, substantially in accordance with Form 2, specifying such facilities or further facilities:

Provided that no such notice shall be given until the tribunal has received the appellant's statement of the grounds of his appeal or, if the appellant does not furnish such a statement, until the time limited by paragraph (1) of this rule has expired.

The tribunal shall give to the appellant an opportunity of objecting to any notice under paragraph (2) of this rule on the grounds that the facilities or further facilities specified therein are unnecessary or unreasonable and may, after considering any such objection, modify or withdraw the notice.
