A question in an appeal which is required to be determined in accordance with section 47 or 47B of the Management Act or section 222(4A) of the Inheritance Tax Act 1984 may be referred to the appropriate tribunal by the Tribunal before whom the appeal is brought or, if the hearing of the appeal has not begun, by an inspector or other officer of the Board.

Where any question in an appeal has been referred to another tribunal in accordance with section 47 or 47B of the Management Act or section 222(4A) of the Inheritance Tax Act 1984, the Tribunal before whom the appeal is brought may finally determine the remaining questions in the appeal without awaiting the determination of the question referred to the other tribunal.
