Industrial capacity refixation requires fresh parameter changes and reasoned effective dates; unexplained increases and delays cannot stand.

Industrial capacity under the prescribed rules cannot be refixed upward unless there is a fresh and identified change in the governing parameters; an unexplained increase without supporting material is unsustainable. The operative date for applying revised capacity and duty must also be based on a stated and rational basis; shifting that date later without justification is not permitted. The impugned fixation and delayed effective date were set aside, and the matter was remitted for fresh determination after hearing the assessee and recording reasons.

Issues: (i) Whether the annual capacity of the rolling mill could be re-fixed at a figure higher than the earlier determined capacity without any fresh change in the relevant parameters. (ii) Whether the effective date for applying the revised capacity and duty could be shifted to a later date without a stated basis.

Issue (i): Whether the annual capacity of the rolling mill could be re-fixed at a figure higher than the earlier determined capacity without any fresh change in the relevant parameters.

Analysis: The capacity had already been determined after taking into account the reduction in one of the prescribed factors. The later order did not identify any subsequent alteration in the determinants that could justify an increase in capacity. In the absence of any stated basis or fresh material, a higher capacity could not be sustained.

Conclusion: The revised capacity fixation was unsustainable and was set aside in favour of the assessee.

Issue (ii): Whether the effective date for applying the revised capacity and duty could be shifted to a later date without a stated basis.

Analysis: The change in the relevant parameter had been indicated to operate from an earlier month, and the duty consequence had to follow that effective change. No reason was given for postponing the operative date to a later point in the financial year. The apportionment of capacity and duty from a later date therefore lacked support.

Conclusion: The later effective date for applying the revised capacity and duty was not justified and was set aside in favour of the assessee.

Final Conclusion: The appeal succeeded, the impugned order was quashed, and the matter was sent back for fresh determination after giving the assessee an opportunity of hearing and a reasoned basis for the proposed fixation.

Ratio Decidendi: A reassessment of industrial capacity under the prescribed rules must rest on identified changes in the governing parameters and must fix the operative date on a reasoned and supportable basis; an unexplained increase or delayed effective date cannot stand.
