Unjust enrichment bars tax refund where the burden was passed on to purchasers; authority must verify tax collection first.

Tax refund or relief must be withheld where the assessee has passed on the tax burden to purchasers, because the principle against unjust enrichment prevents repayment in such cases. The Andhra Pradesh High Court approved the remand in substance but required the assessing authority to examine whether tax had been collected from purchasers before any refund or relief was granted. The court linked this safeguard to the earlier recognised doctrine and its incorporation in section 33-BB of the Andhra Pradesh General Sales Tax Act. Relief was therefore made conditional on proof that the tax burden had not been transferred.

Issues: Whether the remand ordered by the Tribunal should be modified to require the assessing authority to consider whether tax had been collected from purchasers and to apply the rule against unjust enrichment.

Analysis: The Tribunal had remitted the matter for fresh consideration on the nature of the goods and the applicable rate of tax. In disposing of the revision, the Court accepted that there was force in the Revenue's objection regarding the assessee's failure to appeal, but held that, in the facts of the case, it would not be just to interfere on that ground. The Court instead applied the principle of unjust enrichment, as recognised in its earlier decision and incorporated in section 33-BB of the Andhra Pradesh General Sales Tax Act, and directed the assessing authority to examine whether the assessee had collected tax from purchasers before granting any refund or relief.

Conclusion: The remand was upheld in substance but modified to require consideration of tax collection and unjust enrichment; relief would be denied if tax had already been collected from purchasers, and refund would be available only if the tax had not been so collected.

Final Conclusion: The matter was finally disposed of by sustaining the remand with an added safeguard against unjust enrichment, thereby limiting any monetary relief to cases where the tax burden had not been passed on.

Ratio Decidendi: In tax matters, refund or relief should not be granted where the assessee has passed on the tax burden and would thereby be unjustly enriched; the authority must examine that question before finalising the assessment or granting refund.
