The text distinguishes such statutory liability from ordinary commercial cases involving supplementary invoices or price revisions, which were treated as inapplicable to a levy created by retrospective legislation. On that reasoning, interest was not payable from the original clearance date; it arose only from the first day of the month succeeding the retrospective amendment's effective date. en-us Wed, 22 Jan 2014 00:00:00 +0530 Fri, 26 Sep 2014 08:57:00 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=251739 Interest under Section 11AB on differential excise duty was held to run only from the date the duty first became legally payable, where the liability arose solely because of a retrospective amendment deeming the process to be manufacture.
