https://www.taxtmi.com/caselaws?id=73104 Rule 173PP(10) required excise assessment at the close of the accounting year, with the limitation under Rules 10 and 11 computed from that close subject to the rule's modification. Where the department already knew of the assessee's manufacturing activity and no suppression of vital facts was shown, only the shorter limitation period applied. A show cause notice dated 27-3-1979 was therefore out of time for the year ended 30-6-1978, and it could not validly sustain duty for the year ended 30-6-1979 because that accounting year had not yet closed and assessment was not due. en-us Mon, 30 Sep 1985 00:00:00 +0530 Sat, 28 May 2011 10:46:28 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=73104 Rule 173PP(10) required excise assessment at the close of the accounting year, with the limitation under Rules 10 and 11 computed from that close subject to the rule's modification.
