Post-contract tax variation claims may be examined for reimbursement under Section 64A principles after GST transition.

A claim for reimbursement of tax burden arising from services rendered across the pre-GST to GST transition was not granted by direct mandamus. The Court noted that the principle reflected in Section 64A of the Sale of Goods Act, 1930 applies where tax is imposed or increased after contractual arrangements, and permitted the petitioner to approach the respondents for examination of reimbursement on that basis. The matter was left to the competent authorities for consideration in accordance with the tax-variation principle, without a merits determination by the Court.

Issues: Whether the petitioner was entitled to a direct mandamus for disbursement of service tax, interest and penalty amounts, and whether the claim relating to increased tax burden after GST implementation could be examined by the respondents in the light of Section 64A of the Sale of Goods Act, 1930.

Analysis: The claim arose from services rendered during the transition from the pre-GST regime to the GST regime. The Court noted that the principle embodied in Section 64A of the Sale of Goods Act, 1930 governs situations where tax is imposed, increased, decreased or remitted after contractual arrangements, and that the petitioner's grievance concerned reimbursement of tax burden arising after implementation of GST. Instead of deciding the claim on merits, the Court considered it appropriate to allow the petitioner to approach the respondents for reimbursement based on the statutory principle and the change in tax regime.

Conclusion: The petitioner was not granted a direct writ of mandamus for immediate payment, but was permitted to approach the first to fourth respondents for reimbursement of the tax arising from the increase in tax rate after GST implementation.

Final Conclusion: The matter was disposed of by leaving the claim to be examined by the respondents in accordance with the governing principle on tax variation, without a merits determination by the Court.

Ratio Decidendi: Where a claim concerns increased tax burden arising after contractual performance and the dispute is not adjudicated on merits, the Court may permit the claimant to seek reimbursement before the competent authority by applying the statutory principle on post-contract tax variation.
