activity as exempted service under a deeming fiction, the same cannot have retrospective effect. Prior to the amendment of Notification No. 13/2011-CE (NT) whereby, the trading activity was made deemed exempted service, there was no clarity even with the department and therefore, the amendment was brought. Further, the appellant’s records have been audited regularly during the relevant period and department after knowing that the appellant are involved in trading activity and availing the Cenvat credit on various input services, some of which are common input service did not raise any objection. Therefore, in our considered view, firstly, there was a bonafide belief that trading activity will not attract any demand under Rule 6 (3), secondly,in fact, there is absolutely no suppression of fact on the part of the appellant. Therefore, we also observed that as per various judgments cited by the appellant, it has been held that the effect of trading activity being exempted service is prospective and not retrospective. Therefore on the issue, there were multiple litigations, this also shows that there is no malafide intention on the part of the appellant to invoke extended period of demand.
