Stamp-Duty Guideline Value as the Statutory Baseline in NH Act Acquisitions: Single, Dissimilar Sale Exemplar as “Patent Illegality”

1. Introduction

This Supreme Court decision in Project Director National Highways Authority of India v. Alfa Remidis Ltd, Nagpur (2026 INSC 480, decided on 12-05-2026) addresses how compensation must be determined for land acquired under the National Highways Act, 1956 (“NH Act”), particularly when the matter reaches arbitration under Section 3G(5), and is later tested under Sections 34 and 37 of the Arbitration and Conciliation Act, 1996 (“Arbitration Act”).

The appellant, National Highways Authority of India (NHAI), challenged an enhanced compensation rate granted to the respondent landowner, Alfa Remidis Ltd., for acquisition of 1,394 sq. meters in Mouza Pardi (Rithi), Tahsil Saoner, District Nagpur, for four-laning of NH No. 547-E.

Key issues

  1. Whether compensation determination under NH Act acquisitions must strictly follow Section 26 of the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013 (“2013 LA Act”).
  2. Whether an arbitrator can adopt a single sale deed of a dissimilar land type (residential plot) to value land used for industrial purpose.
  3. Whether ignoring Section 26 methodology amounts to “patent illegality” warranting setting aside under Section 34(2A) of the Arbitration Act.

2. Summary of the Judgment

The Supreme Court allowed NHAI’s appeal and held that the Arbitrator’s adoption of a single sale exemplar for a residential plot in a nearby village to value industrial-use land was contrary to the statutory mandate in Section 26 of the 2013 LA Act. This constituted patent illegality on the face of the award.

The Court restored a statutory-compliant valuation by applying Section 26(1)(a) (stamp-duty guideline value / Ready Reckoner), fixing compensation at ₹2,020 per sq. meter (instead of ₹3,588 per sq. meter adopted by the arbitrator and restored by the High Court), along with all consequential statutory benefits under the 2013 LA Act. The respondent’s withdrawal of ₹50,00,000 was directed to be adjusted.

3. Analysis

A. Precedents Cited

(i) National Highways Authority of India v. P. Nagaraju alias Cheluvaiah and another

The Court relied on National Highways Authority of India v. P. Nagaraju alias Cheluvaiah and another (2022) 15 SCC 1 to reaffirm that, after the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement (Removal of Difficulties) Order, 2015 (effective 01.09.2015), compensation determination for acquisitions under statutes listed in the Fourth Schedule—including the NH Act (Serial No. 6)—must apply the 2013 LA Act’s compensation framework.

The controlling takeaway from this precedent, as invoked in the present case, is that Sections 26 to 28 of the 2013 LA Act govern the determination of compensation even when acquisition is under the NH Act and the dispute is processed via Section 3G arbitration.

(ii) MADHYA PRADESH ROAD DEVELOPMENT CORPORATION v. VINCENT DANIEL and others

The Court cited MADHYA PRADESH ROAD DEVELOPMENT CORPORATION v. VINCENT DANIEL and others (2025) 7 SCC 798 to explain the internal logic of Section 26(1)(b): “average sale price” implies reliance on multiple comparable transactions, because a single transaction may not provide “adequate and reliable data.” This precedent reinforced that Section 26 is not a loosely-guiding factor but a structured statutory methodology.

B. Legal Reasoning

(i) Section 26 of the 2013 LA Act is mandatory and structured

The Court set out Section 26(1) and emphasized its architecture: the Collector (and by extension the arbitral decision-maker valuing compensation) must select the highest among:

  • Section 26(1)(a): stamp-duty guideline value (market value specified for registration purposes in the area);
  • Section 26(1)(b): average sale price for similar type of land in the nearest village/vicinity (computed via Explanations 1–4);
  • Section 26(1)(c): consented amount (not relevant here).

Crucially, when proceeding under clause (b), the statute demands an average determined through the mechanism in Explanations 1 to 4— including using registered transactions from the immediately preceding three years and taking into account one-half of the transactions with the highest prices. This scheme is fundamentally inconsistent with “picking” a single sale deed.

(ii) “Similar type of land” is a hard constraint, not a loose comparison

Alfa Remidis’ case was that its land was used for an industrial purpose (paracetamol production unit). Yet the Arbitrator applied a rate derived from a sale deed dated 29.03.2017 for a small residential plot (195.09 sq. meters) in another village. The Supreme Court held that such lands were not “similar type” for Section 26(1)(b). Therefore:

  • the exemplar was ineligible for clause (b) comparability; and
  • even if it were comparable, using a single deed violates the statutory “average sale price” method.

(iii) Why the Court applied Section 26(1)(a) (Ready Reckoner) here

The respondent itself relied on the Ready Reckoner rate of ₹2,020 per sq. meter (Zone 4, highway-abutting lands; Mouza Pardi (Rithi) included). The Supreme Court held that this is the statutory input contemplated by Section 26(1)(a). Since the arbitrator’s clause (b) approach was unlawfully executed, the legally correct basis was clause (a) on the record before the Court.

(iv) Patent illegality under Section 34(2A) of the Arbitration Act

The Court drew a line between:

  • mere erroneous application of law or reappreciation of evidence (generally insulated by the proviso to Section 34(2A)), and
  • ignoring a binding statutory mandate governing the valuation method (treated as patent illegality).

Here, the arbitrator did not simply “prefer one plausible view”; he discarded the statutory valuation architecture of Section 26(1)(b) and its Explanations and adopted a prohibited approach (single, dissimilar exemplar). This, the Court held, fell outside the protective shield of the proviso and justified interference.

C. Impact

(i) Tightening arbitral discretion in statutory-compensation arbitrations

The judgment signals that Section 3G(5) arbitration under the NH Act is not “free-form valuation.” Arbitrators must comply with Section 26 methodology and will face Section 34(2A) scrutiny if they bypass it.

(ii) Reinforcement of guideline value (Ready Reckoner) as an anchor

The decision strengthens the practical role of Section 26(1)(a)—stamp-duty guideline value—particularly where:

  • reliable, multiple comparable sale deeds of similar type are unavailable; or
  • the attempted exemplars are dissimilar or methodologically non-compliant with “average sale price.”

(iii) Consequences for evidence strategy in compensation claims

Claimants seeking higher valuation under Section 26(1)(b) must now anticipate stricter demands: they should marshal multiple sale deeds, within the relevant time window, of similar type land, enabling the statutory averaging exercise. Reliance on a single high-value outlier transaction is unlikely to survive.

4. Complex Concepts Simplified

  • Ready Reckoner / guideline value: Government-notified land rates used for calculating stamp duty during registration. Section 26(1)(a) treats this as a legally recognized “market value” input for compensation.
  • “Average sale price” (Section 26(1)(b)): Not “any one” sale deed. It requires collecting several comparable sales and computing an average using the statutory filter (including using half of the highest-priced transactions).
  • “Similar type of land”: Land comparability depends on nature/use and characteristics; residential plot prices cannot automatically value industrial-use land.
  • Patent illegality (Section 34(2A)): A glaring legal flaw apparent on the face of the award—such as ignoring a mandatory statutory method—permitting courts to set aside the award even though courts generally avoid merits reappraisal in arbitration.
  • NH Act + 2013 LA Act linkage: Due to the 2015 Removal of Difficulties Order and the NH Act being in the Fourth Schedule, compensation determination for NH acquisitions must use the 2013 LA Act framework (Sections 26–28).

5. Conclusion

The Supreme Court’s ruling establishes a clear operational rule for NH Act acquisition compensation disputes: statutory valuation methodology under Section 26 of the 2013 LA Act is mandatory, and arbitral awards that determine market value by relying on a single sale exemplar—especially one involving a dissimilar land type—are vulnerable as patently illegal under Section 34(2A) of the Arbitration Act.

By resetting the compensation to the Ready Reckoner rate under Section 26(1)(a) (₹2,020 per sq. meter), the Court both corrected the award on the facts and provided a doctrinal signal: arbitral discretion in statutory-compensation regimes ends where the statute’s valuation algorithm begins.
