(1) Any power conferred or any duty imposed upon the relevant tax authority may be exercised or performed by it, by an officer authorised generally, or specifically, in that behalf.

(2) Notwithstanding the provisions of subsection (1) of this section, the relevant tax authority may, at any time and at its discretion, reverse or modify any decision of any officer, affecting any tax or taxable income, whether or not the discretion to make the decision was conferred on the officer by any provision of this Act or any other tax law or whether or not the officer was authorised by it to make the decision, and the reversal or modification of the decision shall have effect as if it were the original decision made in respect of the matter concerned.
