Collector Of Central Excise, Hyderabad vs Chemphar Drugs & Liniments, Hyderabad on 14 February, 1989
Again in the case of Collector of C. Excise v. Chemphar Drugs and Liniments, reported in 1989 (40) E.L.T. 276, the Supreme Court has held that "in order to make the demand of duty sustainable beyond a period of six months and upto a period of 5 years in view of the proviso to Section 11A of the Act, it has to be established that the duty of excise has not been levied or paid or short-levied or short-paid or erroneously refunded by reasons of either fraud or collusion or wilful mis-statement or suppression of facts or contravention of the provisions of the Act or Rules made thereunder, with the intent to evade payment of duty. Something positive other than mere inaction or failure on the part of the manufacturer or producer or conscious or deliberate withholding of information when the manufacturer knew otherwise, is required before he is saddled with any liability, before the period of six months".
