Modvat invoice defects can defeat credit when mandatory transport particulars are missing; pre-commencement interest cannot be levied.

Mandatory particulars in Modvat invoices, including mode of transport, vehicle registration number and time of despatch, were treated as essential for verifying receipt of goods. Because those particulars were absent, the defect was substantive rather than merely procedural, so Modvat credit and penalty were sustained against the assessee. Interest under Rule 57-I(3) could not be charged for April-May 1995 because that provision came into force only on 31-5-1995; the statutory basis for interest was not in force during the relevant period, so the interest demand was set aside.

Issues: (i) Whether Modvat credit could be denied on the ground that the invoices suffered from defects such as omission of vehicle details and time of despatch, and whether such defects were merely procedural or went to the validity of the documents; (ii) Whether interest under Rule 57-I(3) could be sustained for the period when that provision had not yet come into force.

Issue (i): Whether Modvat credit could be denied on the ground that the invoices suffered from defects such as omission of vehicle details and time of despatch, and whether such defects were merely procedural or went to the validity of the documents.

Analysis: The invoices were required, under the governing notification issued under Rule 57GG, to contain essential particulars including the mode of transport, vehicle registration number and time of despatch. Those particulars were material for verifying actual receipt of the goods. The defects were not treated as mere technical irregularities, and the plea of substantive compliance was held insufficient where the basic document itself could not be accepted as valid for Modvat purposes.

Conclusion: The disallowance of Modvat credit and the penalty were upheld, against the assessee.

Issue (ii): Whether interest under Rule 57-I(3) could be sustained for the period when that provision had not yet come into force.

Analysis: The relevant interest provision came into force only from 31-5-1995, whereas the invoices and the disputed period related to April-May 1995. As the statutory basis for charging interest was not in force during the relevant period, the interest demand could not be sustained.

Conclusion: The interest demand was set aside, in favour of the assessee.

Final Conclusion: The duty demand and penalty were sustained, but the interest component was deleted, resulting in partial relief to the assessee.

Ratio Decidendi: Where mandatory particulars required for a duty-paying document are absent, the defect is substantive and Modvat credit can be denied; interest cannot be levied for a period anterior to the commencement of the charging provision.
