Petitioner admitted wrongful availment and retention of excess transitional input tax credit and later reversed it; interest liability for wrongful availment is mandatory under the applicable GST interest provisions and was computed for the period of retention. The adjudicating and appellate authorities considered and rejected petitioner's contentions that interest required a separate show-cause notice, should be computed only on net tax, or that mere portal reflection did not constitute utilisation; both orders were upheld and the petition dismissed.
