Modvat credit on defective inputs remains available when material enters the manufacturing stream and is later rejected during processing.

Modvat credit on float glass used in an integrated manufacturing sequence could not be denied merely because some pieces were later found defective and rejected before the final product was completed. Once the input had entered the manufacturing stream, Rules 57A and 57D protected credit even if part of the material became waste or was rejected during the process. The Court also noted that a settlement order based on the mistaken premise that such input was not used in or in relation to manufacture, or on the supplier's reimbursement being decisive, reflected a misdirection in law and was open to judicial review.

Issues: (i) Whether Modvat credit could be denied on float glass which, after being subjected to the manufacturing process, was found defective and rejected before the final product was completed; (ii) Whether the Settlement Commission had misdirected itself in law in holding that such input was not used in or in relation to manufacture and in treating the supplier's reimbursement as decisive.

Issue (i): Whether Modvat credit could be denied on float glass which, after being subjected to the manufacturing process, was found defective and rejected before the final product was completed.

Analysis: The relevant question was whether the input had entered the manufacturing stream. The process of cutting, marking, breaking off, grinding, washing and inspection formed an integrated manufacturing sequence, and the defect was detected only after the input had undergone these stages. Rule 57A permitted credit on inputs used in or in relation to manufacture, and Rule 57D protected credit from denial merely because part of the input became waste or was rejected during the course of manufacture. Once the float glass was used in the manufacturing process, later rejection of some pieces did not deprive the manufacturer of credit.

Conclusion: The denial of Modvat credit on that basis was not sustainable and the assessee was entitled to credit on the inputs used in the manufacturing process.

Issue (ii): Whether the Settlement Commission had misdirected itself in law in holding that such input was not used in or in relation to manufacture and in treating the supplier's reimbursement as decisive.

Analysis: The Commission proceeded on an erroneous premise that because defects were inherent or reimbursed by suppliers, the input was not used in manufacture. That approach ignored the statutory width of the expression 'used in or in relation to manufacture' and the effect of Rule 57D. The Court held that the Commission's reasoning disclosed misdirection in law and non-application of mind to the actual stage at which rejection occurred, which justified interference under writ jurisdiction notwithstanding the finality attached to settlement orders.

Conclusion: The Commission's order could not stand and was liable to be set aside for fresh consideration.

Final Conclusion: The petition succeeded, the settlement order was interfered with, and the matter was required to be reconsidered afresh in accordance with law.

Ratio Decidendi: Where an input has entered an integrated manufacturing process, credit cannot be denied merely because some quantity is later rejected as defective or waste during that process; a settlement order founded on an erroneous understanding of this principle is open to judicial review.
