An assessment order issued under the GST regime without a Document Identification Number was treated as non-est and unsustainable, following the principle that a DIN is mandatory for validity.

The assessment order was set aside and the matter remanded to the Assessing Officer for fresh consideration in accordance with law, with exclusion of the intervening period for limitation purposes.
