Section 3 of the Relaxation Act, 2020 while extending the time limits for taking action and making compliances in the specified Acts upto 31.12.2020 the power was given to the Central Government to extend the time further by issuing a notification. This was the only power vested in the Central Government. As a piece of delegated legislation the notifications issued in exercise of such powers, had to be within the confines of such powers. In plain terms under subsection (1) of Section 3 of the Relaxation Act, 2020 the Government of India was authorized to extend the time limits by issuing notifications in this regard. Issuing any explanation touching the provisions of the Income Tax Act was not part of this delegation at all. The CBDT while issuing the notifications dated 31.03.2021 and 27.04.2021 when introduced an explanation which provided by way of clarification that for the purposes of issuance of notice under Section 148 as per the time limits specified in Section 149 or 151, the provisions as they stood as on 31.03.2021 before commencement of the Finance Act, 2021 shall apply, plainly exceeded its jurisdiction as a subordinate legislation. The subordinate legislation could not have travelled beyond the powers vested in the Government of India by the parent Act. Even otherwise it is extremely doubtful whether the explanation in the guise of clarification can change the very basis of the statutory provisions. If the plain meaning of the statutory provision and its interpretation is clear, by adopting a position different in an explanation and describing it to be clarificatory, the subordinate legislature cannot be permitted to amend the provisions of the parent Act. Accordingly, these explanations are unconstitutional and declared as invalid.
