Agricultural implements classification preserved for water pumping sets; retrospective amendment could not justify later tax enhancement.

Water pumping sets used for agricultural purposes were treated as agricultural implements under the relevant sales tax notification for assessment year 1970-71, so the concessional 3 per cent rate applied. A later retrospective amendment could not be extended back beyond the inception of the 1971 Schedule to alter the meaning of that earlier notification, and the validation provision in section 3-AB could not enlarge the scope of the notified goods for the past period. On that basis, reassessment under section 22 to enhance tax for 1970-71 was not justified, and the excess levy was held refundable.

Issues: (i) Whether water pumping sets used for agricultural purposes were "agricultural implements" under the relevant notification and were therefore taxable at 3 per cent for the assessment year 1970-71. (ii) Whether the retrospective amendment made by section 9 of the Uttar Pradesh Sales Tax (Amendment) Act, 1974, read with section 3-AB of the Act, displaced that classification so as to justify enhancement of tax under section 22 of the U.P. Sales Tax Act.

Issue (i): Whether water pumping sets used for agricultural purposes were "agricultural implements" under the relevant notification and were therefore taxable at 3 per cent for the assessment year 1970-71.

Analysis: The relevant notification in force during the assessment year prescribed tax at 3 per cent for agricultural implements other than those worked by human or animal power and tractors, including their parts and accessories. The earlier Full Bench view had already held that water pumping sets used for pumping water to fields fell within that expression under the materially similar earlier notification. The later notification used the same language, and no intervening statutory change applicable to the assessment year had altered the position before the 1971 amendment came into force.

Conclusion: Water pumping sets were agricultural implements for the assessment year 1970-71 and were liable to tax at 3 per cent.

Issue (ii): Whether the retrospective amendment made by section 9 of the Uttar Pradesh Sales Tax (Amendment) Act, 1974, read with section 3-AB of the Act, displaced that classification so as to justify enhancement of tax under section 22 of the U.P. Sales Tax Act.

Analysis: The retrospective deeming in section 9 of the 1974 Amendment Act was held to operate only from the inception of the First Schedule introduced by the 1971 Amendment Act and not to a period before that schedule itself came into existence. Section 3-AB was treated as a validation provision regularising levy under the specified notifications, not as enlarging the scope of the expressions used in those notifications or extending the retrospectivity of later amendments. Since the original assessment for 1970-71 was not erroneous, there was no basis for reassessment under section 22.

Conclusion: The retrospective amendment did not authorise enhancement of tax for the assessment year 1970-71, and the section 22 correction was invalid.

Final Conclusion: The reassessment and appellate enhancement were unsustainable, and the assessee remained entitled to assessment of the pumping set turnover at 3 per cent with consequential refund of the excess tax collected.

Ratio Decidendi: A retrospective deeming amendment to a later statutory schedule cannot be stretched beyond the date of the schedule's own inception so as to alter the meaning of an earlier taxing notification, and a validation clause cannot be used to expand the scope of the notified goods for a past assessment period.
