Integrated manufacturing process principle denies exemption where power is used in an ancillary bleaching step and suppression sustains limitation.

Use of power in a preliminary or ancillary step can amount to use of power in the manufacturing process where that step is integral to the continuous operation. On that reasoning, lifting and transferring water for kiering and bleaching with power was treated as part of the integrated process, so the exemption was denied. Separate records also indicated suppression of material facts, including non-disclosure of power use and failure to maintain and produce relevant documents, which justified invocation of the extended limitation period. The demand therefore survived the time-bar challenge.

Issues: (i) Whether the use of power for lifting water and pouring it into the kier and bleaching vessel amounted to processing fabrics with the aid of power so as to deny exemption under the relevant notification; and (ii) whether the demand was barred by limitation on the ground that the extended period was not available.

Issue (i): Whether the use of power for lifting water and pouring it into the kier and bleaching vessel amounted to processing fabrics with the aid of power so as to deny exemption under the relevant notification.

Analysis: The exemption turned on whether the fabrics were processed with the aid of power. The reasoning adopted the principle that a manufacturing process is not confined to the core operation alone, but includes preliminary and ancillary steps which are integrally connected with the continuous process of manufacture. Since water was an essential ingredient for kiering and bleaching, its lifting and transfer by power formed part of the integrated manufacturing operation and could not be isolated as a merely incidental step. On that approach, the earlier view that power used only in an ancillary step would not matter was held inconsistent with the governing principle.

Conclusion: The assessee was not entitled to the exemption, because power was used in a step integrally connected with the bleaching process.

Issue (ii): Whether the demand was barred by limitation on the ground that the extended period was not available.

Analysis: The finding of suppression was supported by the absence of disclosure to the department about the use of power, the failure to maintain and produce relevant records, and the omission to furnish the material facts at the stage of obtaining licence and in subsequent correspondence. Those circumstances justified invocation of the extended period and sustained the demand as time-barred plea failed.

Conclusion: The demand was within limitation and the plea of time bar was rejected.

Final Conclusion: The appeal was dismissed as the exemption claim failed on merits and the limitation challenge also failed.

Ratio Decidendi: Power used in a preliminary or ancillary step is treated as use of power in the manufacturing process when that step is an integral part of the continuous process of manufacture, and suppression of material facts justifies invocation of the extended period of limitation.
