Hindusthan Malleables And Forgings ... vs Union Of India (Uoi) on 18 December, 1991
"Reliance has been placed on the decision of the Supreme Court in Padmini Products v. Collector of Central Excise, 1989 (43) E.L.T. 195 (SC) wherein it has been held that extended period of five years is inapplicable for mere failure or negligence to pay duty when there was scope for doubt that the goods were not dutiable unless there is evidence that the manufacturer knew that the goods were liable to duty and he due to fraud or collusion or wilful misstatement or suppression of facts in contravention of any provision of the Act and the Rules, cleared the goods without payment of duty, the extended period of five years limitation could be invoked."
