Limitation and installed capacity under an exemption notification: clubbing of paper and straw board units upheld, but extended period rejected for no suppression.

Where the department already had the basic facts, including separate manufacture in paper and straw board units and approved classification lists, the extended limitation period could not be invoked in the absence of suppression or withholding of material facts, so the demand was held time barred. On Notification No. 128/77, the installed capacity had to be assessed for the paper mill as a whole rather than by treating the paper and straw board plants separately, because both units formed one establishment under the same management in the same complex. The exemption was therefore to be computed by clubbing the capacities of both units.

Issues: (i) whether the demand for Rs. 2,85,544.59 was barred by limitation in the absence of suppression or withholding of material facts; and (ii) whether, for the purpose of Notification No. 128/77, the installed capacity of the paper unit and the straw board unit was required to be clubbed.

Issue (i): whether the demand for Rs. 2,85,544.59 was barred by limitation in the absence of suppression or withholding of material facts.

Analysis: The assessee had disclosed that both paper and straw board were manufactured in separate units, had filed common classification lists, and had furnished the information asked for by the departmental authorities. The authorities were already in possession of the basic facts and approved the classification lists without raising any query on the applicability of the exemption slab. In such circumstances, the extended period could not be invoked merely because the authorities later took a different view of the notification.

Conclusion: The demand of Rs. 2,85,544.59 was time barred and the finding against the Revenue was upheld.

Issue (ii): whether, for the purpose of Notification No. 128/77, the installed capacity of the paper unit and the straw board unit was required to be clubbed.

Analysis: The exemption was linked to a paper mill and the annual installed capacity of the mill in respect of all varieties of paper and paper boards. The two units were situated in the same complex, operated under the same management, and formed part of one establishment. On that construction, the relevant unit for exemption was the mill as a whole and not each plant separately.

Conclusion: The installed capacity of the paper and straw board units had to be clubbed, and the assessee was not entitled to compute the exemption only on the paper plant capacity.

Final Conclusion: The Revenue's appeal failed on limitation, while the assessee's appeal failed on the merits of exemption under the notification, and the orders of the Collector (Appeals) were sustained.

Ratio Decidendi: For an exemption notification based on the installed capacity of a paper mill, the relevant unit is the mill as a whole, and where the material facts are already before the department and classification lists are approved without objection, the extended period of limitation cannot be invoked absent suppression.
