Misuse of registration certificate cannot be inferred from sales to a cancelled dealer or non-production of accounts alone.

Misuse of a dealer's registration certificate could not be inferred merely because sales were made to a purchaser whose registration had been cancelled or because account books were not produced for verification. Those facts might affect entitlement to deduction or justify best judgment assessment, but they did not by themselves establish misuse within the power to cancel registration for sufficient cause. The High Court therefore held that cancellation of the assessee's registration certificate on the alleged ground of misuse was without jurisdiction and could not stand. The cancellation order was quashed, with costs awarded against the respondents.

Issues: Whether the Assessing Authority could cancel the dealer's registration certificate on the ground of misuse where the assessee had sold goods to a purchaser whose registration certificate had been cancelled and had not produced account books for verification.

Analysis: The statutory scheme allowed deduction for sales to a registered dealer only if the prescribed declaration was furnished. If the purchaser's registration had been cancelled, or if the purchaser was fictitious, the assessee could lose the deduction and be assessed accordingly. But such consequences did not convert the seller's conduct into misuse of its own registration certificate. Non-production of account books could justify best judgment assessment under the relevant assessment provision, but it did not by itself establish misuse within the meaning of the power to cancel registration for sufficient cause including misuse.

Conclusion: The cancellation of the assessee's registration certificate on the alleged ground of misuse was without jurisdiction and could not be sustained.

Final Conclusion: The appeal succeeded and the cancellation order was quashed, with costs awarded against the respondents.

Ratio Decidendi: Cancellation of a registration certificate for misuse cannot rest merely on sales to a dealer whose registration has been cancelled or on non-production of accounts; at most, those facts may affect deduction or assessment, not the existence of jurisdiction to cancel the certificate.
