The Allahabad High Court has delivered a significant ruling on the arbitrability of tax disputes arising from public works contracts, particularly concerning Goods and Services Tax (GST). The judgment clarifies the boundaries between contractual tax liability and statutory tax assessment, providing critical guidance for practitioners handling infrastructure disputes.
Background & Facts
The Genesis of the Dispute
The dispute originated from a contract dated 27.04.2016 between the Uttar Pradesh Public Works Department (appellant) and M/s Vriddhi Infratech India Pvt. Ltd. (respondent) for the widening and strengthening of Bilraya-Panwari Road (SH-21) and Nepalpur-Bijwar Road (ODR) in Sitapur District.

Relief Sought
The appellant sought setting aside of the award under Section 37 of the Arbitration and Conciliation Act, 1996, challenging the arbitrability of the tax dispute and the applicability of the MoRTH SOP over state government orders.
The Legal Issue
The central question was whether a dispute relating to the calculation and payment of GST in a public works contract is arbitrable, and if so, whether the MoRTH SOP or the state government orders govern the calculation.
Arguments Presented
For the Appellant
The appellant argued that tax disputes are non-arbitrable when they involve statutory determination by tax authorities, as the GST Act is a complete code in itself. It contended that the dispute pertained to the quantum and manner of GST calculation, which falls within the exclusive domain of the taxing authority. The appellant also argued that the MoRTH SOP was not binding on the state government department, as it was a directory document applicable only to EPC contracts, not item rate contracts. It further argued that the award was inconclusive as it subjected the GST liability to final assessment by the GST authorities.
For the Respondent
The respondent argued that the dispute was arbitrable as it pertained to contractual tax liability, not statutory tax assessment. It contended that the MoRTH SOP was applicable as the contract incorporated MoRTH technical specifications, and the state government orders were not binding on the respondent. The respondent also argued that the arbitrator had considered expert evidence and that the award was based on material evidence.
The Court's Analysis
The Court examined the arbitrability of tax disputes by distinguishing between disputes that can be resolved within the contract and those requiring statutory determination. It held that disputes relating to which party is contractually liable to pay tax or reimbursement of tax paid are arbitrable, while disputes involving determination of tax rates, classification, or quantum of tax liability are non-arbitrable.
The Court noted that the dispute in the instant case pertained to the manner of GST calculation, not the liability to pay GST. It held that the dispute was arbitrable as it arose from the contract and did not involve statutory determination by the taxing authority.
On the applicability of the MoRTH SOP, the Court held that the contract incorporated MoRTH technical specifications only for engineering standards, not tax provisions. It found that the MoRTH SOP was a directory document applicable only to EPC contracts, not item rate contracts, and that the state government orders were binding on the appellant department. The Court held that the Sole Arbitrator erred in applying the MoRTH SOP without material evidence or contractual basis.
The Court also held that the award was patently illegal as it subjected the GST liability to final assessment by the GST authorities, rendering the award inconclusive. It noted that the GST Act provides for self-assessment and final determination by tax authorities, and that the arbitrator could not act as an assessing officer.
"The Sole Arbitrator has merely proceeded in a compartmentalized way i.e. to say, it held that the technical specifications were borrowed in the contract, therefore, the MoRTH guidelines even for tax purposes would become applicable, consequently, the formula given for the EPC contracts would be applicable to the instant contract despite the said contract being an item rate based contract and as a fortiorari, the Government Orders have been held to be not applicable."
The Verdict
The High Court partly allowed the appeal, setting aside the award to the extent it awarded Rs. 11,35,80,273/- for GST, penalty, and interest. The Court held that the findings on issues 2 to 4 and 8 to 9 were unsustainable and severed them from the award. The Court remitted the matter to the Arbitral Tribunal for fresh adjudication of these issues, while protecting the award of Rs. 66,500/- under issue 10 and the finding on issue 1, which were based on consensus.
What This Means For Similar Cases
Tax Disputes Are Arbitrable Only When Rooted in Contract
- Contractual tax liability (e.g., which party pays tax) is arbitrable.
- Statutory tax assessment (e.g., tax rate, quantum, classification) is non-arbitrable and must be determined by tax authorities.
- Practitioners must frame disputes carefully to avoid non-arbitrability challenges.
Government Orders Bind State Departments Unless Statutorily Overridden
- Executive instructions (e.g., government orders) bind state departments unless overridden by statute.
- Directory documents (e.g., MoRTH SOP) are not binding unless incorporated into the contract.
- Contracts must explicitly incorporate tax provisions to override government orders.
Awards Must Be Conclusive and Not Subject to Statutory Assessment
- Arbitral awards must be final and conclusive, not subject to statutory assessment or final determination by authorities.
- Arbitrators cannot act as assessing officers or delegate statutory functions to private forums.
- Awards that subject liability to final assessment are patently illegal and liable to be set aside.
Severability Doctrine Applies to Partially Invalid Awards
- Courts can sever invalid portions of awards and preserve valid portions.
- Severance is permissible only where claims or parts of the award are legally and pragmatically severable.
- Courts cannot modify awards on debatable errors; only patent illegality is curable.
