Under the 2017 Act, a single show-cause notice covering multiple financial years is impermissible because limitation applies independently to each year and cannot be bypassed by clubbing years.

The composite notice, consequential order-in-original and related steps were quashed, while revenue authorities remained free to initiate fresh proceedings in accordance with law.
