Commissioner Of Sales Tax vs Madhu Chemical Works on 6 January, 1988
21. The distinction between an advertent mistake or omission and change of opinion is well-settled. In a case where a particular point has been considered on merits, and a view is taken, it would not be a case of inadvertent mistake or omission, if it is found that the view taken earlier was wrong. It would be a case of change of opinion, but if it is not so, then it would be a case of non-application of mind and certainly an action would be justified under Section 21 of the Act [see Commissioner of Sales Tax v. Steel Engineering Corporation [1981] 48 STC 432 (All.)].
