Clause 120 - Retrospective effect to notification issued under clause (i) of section 20 of Integrated Goods and Services Tax Act read with subsection (2) of section 7 of Central Goods and Services Tax Act.

Retrospective effect for a GST notification established, with a bar on refunds for tax already collected under prior treatment.

The provision deems a specified Government notification under the Integrated Goods and Services Tax framework to have been in force from an earlier commencement date for all purposes, thereby giving it retrospective effect. It further bars refunds of integrated tax already collected which would not have been collected had that notification been treated as effective from the earlier commencement date.
