A later explanatory notification could not be given retrospective effect to validate the excise demand, because delegated rule-making power does not include retrospective operation unless expressly authorised. The demand was therefore unsustainable, the exemption applied, and the appellant succeeded. en-us Wed, 15 Oct 1969 00:00:00 +0530 Sat, 09 Aug 2014 10:35:00 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=160436 An exemption notification for cotton yarn was construed in light of the rule-making authority's intended meaning of "hank"; it was not limited to a rigid commercial or technical sense that excluded yarn cleared in coils longer than a standard hank, and the exemption was available on that basis.
