Retrospective amendment of registration certificate denied where later business changes, not original error, justified no backdated coverage.

Retrospective amendment of a sales tax registration certificate is not available merely because a dealer later seeks to add goods for resale; it requires an error or omission in the original certificate inconsistent with the registration order. Here, cement was excluded when registration was granted because there was then no intrastate purchase of cement, so the certificate correctly reflected the order and contained no clerical or inadvertent mistake. The later request arose from a change in purchasing pattern, not from any defect in the original grant. Retrospective inclusion of cement was therefore refused, and the writ petition was summarily rejected.

Issues: Whether the dealer was entitled to retrospective amendment of his registration certificate to include cement for resale under section 5(1)(aa) of the Bengal Finance (Sales Tax) Act, 1941, from the date of original registration.

Analysis: The authorities had refused coverage for cement when the registration was originally granted because, on the material then before them, there was no intrastate purchase of cement by the dealer. The certificate issued on 4 September 1975 was therefore consistent with the registration order and did not suffer from any inadvertent error or clerical omission. The later request for amendment arose from a subsequent change in the dealer's purchasing pattern and not from any mistake in the original certificate. The statutory power to amend a registration certificate did not justify treating the later amendment as operative retrospectively in the absence of an error in the original grant of registration. The available remedies against the original refusal had not been pursued in time.

Conclusion: The dealer was not entitled to retrospective insertion of cement in the registration certificate, and the writ petition was rightly summarily rejected.

Ratio Decidendi: Retrospective amendment of a registration certificate is not warranted unless the original certificate contains an error or omission inconsistent with the registration order; a later change in business circumstances does not justify retrospective coverage.
