Discretion in penalty quantification under a taxing provision cannot be bypassed by mechanically applying the maximum penalty.

The applicable tax rate for the assessment year was 13%, as the amendment reducing the rate applied to the year in question. Penalty under Section 23 could not be fixed automatically at 150% because the provision authorised only a maximum penalty and required the assessing authority to exercise discretion in quantification. A clarificatory circular was treated as retrospective and supported the conclusion that the authority had wrongly proceeded on the assumption that 150% was mandatory. The penalty determination was therefore set aside and remitted for fresh quantification.

Issues: (i) whether the tax rate applied for the relevant assessment year had to be taken at 13% instead of 16%; and (ii) whether the penalty under Section 23 could be automatically quantified at 150% without an examination of discretion.

Issue (i): whether the tax rate applied for the relevant assessment year had to be taken at 13% instead of 16%.

Analysis: The rate reduction introduced by amendment applied to the assessment year in question. The respondents accepted that the tax rate ought to have been taken at 13%, and there was no surviving dispute on this aspect.

Conclusion: The correct tax rate was 13% and not 16%, in favour of the assessee.

Issue (ii): whether the penalty under Section 23 could be automatically quantified at 150% without an examination of discretion.

Analysis: Section 23 authorises levy of a penalty not exceeding one and a half times the tax payable, which necessarily leaves room for discretion in quantification. The circular issued by the Commissioner was treated as clarificatory and retrospective, and it showed that the assessing authority had proceeded on the mistaken view that 150% penalty was mandatory. The authority had therefore failed to exercise the discretion vested in it and had imposed the maximum penalty mechanically.

Conclusion: Automatic imposition of penalty at 150% was unsustainable, and the matter had to be reconsidered by the assessing authority for fresh quantification, in favour of the assessee.

Final Conclusion: The penalty determination was set aside and the matter was remitted only for fresh quantification of penalty, while the applicable tax rate issue stood resolved in favour of the assessee.

Ratio Decidendi: Where a taxing provision prescribes only the maximum penalty and not the minimum, the assessing authority must exercise discretion in quantifying the penalty and cannot impose the maximum mechanically; a clarificatory circular may operate retrospectively to guide pending assessments.
