Modvat credit may survive invoice defects where duty-paid inputs are verified, received, used in manufacture, and misuse is excluded.

Procedural defects in Modvat invoices, including a handwritten rather than printed serial number, do not by themselves justify denial of credit where the department verifies that the inputs were duty-paid, actually received, used in manufacture, and not capable of misuse. The printed serial number requirement under the invoice procedure is aimed at control and prevention of abuse, but the scheme's substantive conditions prevail when entitlement is otherwise established. The same principle applies to the absence of the words "duplicate for transporter" if overall eligibility is proved and no misuse is possible.

Issues: Whether Modvat credit can be denied where the invoice serial number is handwritten instead of printed, when the inputs are received under duty-paying documents, entered in statutory records, and verified by the department.

Analysis: The requirement of a printed serial number under Rule 52A(6) and the corresponding procedure under Rule 57GG are intended to secure proper control over invoices and prevent misuse. A handwritten serial number does not satisfy the literal requirement of a printed serial number. However, where the proper officer verifies that the goods were duty-paid, were actually received and used in manufacture, and there is no scope for misuse of the invoice, the defect remains a procedural irregularity. The legislative intent behind the Modvat scheme and the subsequent amendment to Rule 57G support grant of credit when the substantive conditions are fulfilled. The same approach applies to the absence of the words 'duplicate for transporter' where the overall entitlement is otherwise established.

Conclusion: Handwritten serial numbers on invoices do not by themselves disentitle Modvat credit if the department verifies that the inputs were duty-paid, received, used, and the invoice was not capable of misuse; the question is answered in favour of the assessee on this limited basis.

Ratio Decidendi: Procedural defects in Modvat invoices do not warrant denial of credit when the substantive requirements of receipt, duty payment, use in manufacture, and absence of misuse are established on verification by the department.
