Introduction
Land acquisition law begins with a fundamental proposition: when the State takes private property for a public purpose, the owner is constitutionally entitled to compensation in accordance with law.
But what happens when the first compensation determination says one thing and a later arbitral award says another?
Suppose an acquisition authority initially values land as agricultural. Years later, an arbitrator considers additional material and concludes that the same land should command a substantially higher value because of its location, use, or development potential.
Has the arbitrator merely corrected the amount of compensation?
Or has the arbitrator effectively changed the legal character of the acquisition itself?
This question becomes particularly significant in acquisitions under the National Highways Act, 1956, where Section 3G provides the statutory mechanism for determining compensation and Section 3G (5) permits an aggrieved party to seek determination by an arbitrator. Section 3G (6) applies the Arbitration and Conciliation Act, 1996 to such proceedings.
The tension is therefore not merely about money.
It concerns the limits of arbitral power.
An arbitrator may be authorised to determine compensation, but can the process of enhancement retrospectively transform the factual or legal basis on which the acquisition was originally valued?
Recent judicial developments show why the answer requires considerably more nuance than either “yes” or “no.”
The acquisition does not begin with the compensation figure
One of the first principles that must be kept clear is that acquisition and compensation are legally distinct questions.
Under the National Highways Act, the acquisition process begins with statutory notifications. Section 3A provides for the declaration of intention to acquire land, while Section 3D deals with the vesting of the land in the Central Government.
Section 3G subsequently deals with the determination of compensation.
This statutory sequence matters.
The acquisition is not created by the compensation award.
The compensation award follows the acquisition.
Consequently, when an arbitrator later enhances compensation, the natural legal assumption is that the arbitrator is correcting the valuation of property already acquired, rather than creating a new acquisition.
This distinction is consistent with the Supreme Court’s reasoning in Union of India v. Parmal Singh, where the Court observed that enhancement by an arbitrator or court relates to the date of acquisition because the enhanced determination represents what ought to have been awarded in the first instance.
The principle is powerful:
A later enhancement ordinarily changes the amount payable, not the date or identity of the acquisition.
But that does not mean that an arbitrator possesses unlimited freedom to reconsider every factual assumption behind the original award.
What exactly does Section 3G(5) permit?
Section 3G(5) of the National Highways Act provides a statutory remedy where the amount determined by the competent authority is disputed.
The dissatisfied party may approach an arbitrator appointed by the Central Government.
This mechanism is designed to provide an avenue for reconsidering compensation.
The arbitrator’s role is therefore not merely administrative.
The proceedings are quasi-judicial, and Section 3G(6) makes the Arbitration and Conciliation Act, 1996 applicable to them.
But the critical point is this:
The arbitrator is determining compensation within the statutory acquisition framework.
The arbitrator is not conducting an entirely fresh acquisition proceeding.
That distinction places a boundary around arbitral authority.
Enhancement is not the same thing as reclassification
Consider a simple example.
A competent authority acquires land for a highway and values it at ₹20 lakh per acre after treating it as agricultural land.
The landowner challenges the valuation.
The arbitrator examines comparable sale transactions and concludes that the appropriate market value should have been ₹35 lakh per acre.
That is ordinarily a straightforward case of enhancement.
The arbitrator has not changed the acquisition.
The same land was acquired under the same notification for the same public purpose. Only the compensation payable for that acquisition has been reconsidered.
Now change the facts.
Suppose the original authority classified the property as agricultural because of its recorded land use, but the arbitrator later declares that it was effectively commercial or industrial land and uses a fundamentally different valuation methodology to determine compensation.
The legal question becomes more difficult.
Is this still merely valuation?
Or has the arbitrator effectively altered the legal character of the acquired property?
The answer depends upon what the statute permits the arbitrator to reconsider and what evidence establishes the property’s relevant characteristics at the legally prescribed valuation date.
Market value is not simply today’s market price
Land acquisition compensation is governed by statutory methodology.
Under the National Highways Act, Section 3G must be read alongside the applicable provisions of the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013.
The valuation exercise is therefore not an unrestricted assessment of what the land might be worth today.
The relevant question is generally:
What was the legally determinable value of the land at the relevant statutory point in time?
This distinction prevents a later arbitrator from simply looking at subsequent appreciation and treating that appreciation as if it existed on the acquisition date.
The purpose of arbitration is to correct the compensation legally due for the acquisition—not to retrospectively rewrite the economic history of the property.
Parmal Singh: Enhancement relates back
The Supreme Court’s decision in Union of India v. Parmal Singh, (2008) 9 SCC 704, is particularly important in understanding the relationship between the original award and later enhancement.
The Court held that where compensation is increased by an arbitrator or court, the enhancement relates to the date of acquisition because the subsequent adjudication determines what should have been awarded originally.
This principle has significant consequences.
It means that enhanced compensation is not ordinarily treated as a new liability arising on the date of the arbitral award.
Instead, the enhanced amount is understood as part of the compensation that was legally payable for the original acquisition.
This explains why statutory interest can, depending upon the governing law, attach to the enhanced amount from the relevant acquisition date.
The principle also reinforces a broader idea:
The arbitral award does not ordinarily create a new acquisition event.
It corrects the financial consequence of an existing one.
The Supreme Court’s decision in Sarjuprasad: Enhancement requires a fair evidentiary process
The Supreme Court decision in Sarjuprasad v. National Highways Authority of India, decided on 4 April 2025, provides another important dimension to this debate.
The case concerned enhancement of compensation under Section 3G(5) of the National Highways Act. The arbitrator had relied upon sale deeds while increasing compensation. The High Court subsequently interfered with the enhancement on the ground that the additional documents had been produced after the arbitral proceedings had effectively closed.
The Supreme Court’s approach emphasises an important procedural principle:
An arbitral tribunal cannot rely upon material in a manner that deprives the opposite party of a fair opportunity to contest it.
This is especially important in land valuation disputes because a single sale deed, valuation report or classification document can substantially alter the compensation payable.
Enhancement therefore requires more than a conclusion that the original authority was wrong.
It requires a legally sustainable evidentiary foundation.
The danger of the “single sale deed”
The problem becomes even more visible in Project Director, National Highways Authority of India v. Alfa Remidis Ltd.
There, the compensation had initially been determined by treating the acquired property as agricultural. The arbitrator subsequently enhanced the compensation substantially by relying upon a sale deed relating to residential land in a neighbouring village.
The Supreme Court held that residential and industrial land could not simply be treated as “similar” land for purposes of the statutory valuation methodology. It further held that the statutory requirement concerning average sale price could not be satisfied by relying upon a solitary and dissimilar sale instance. The award was consequently vulnerable as being patently illegal.
This judgment illustrates the boundary between correction and transformation.
An arbitrator is entitled to correct an inadequate valuation.
But correction must remain within the statutory framework.
An arbitrator cannot enhance compensation merely because another property somewhere nearby was sold at a much higher rate.
The comparable property must actually be comparable.
The statutory methodology must be respected.
Can an arbitrator reconsider the character of the land?
This is where the question becomes particularly interesting.
The answer should not be expressed as an absolute prohibition.
An arbitrator may necessarily have to determine factual characteristics relevant to valuation.
For example, the tribunal may need to examine:
- whether land was agricultural or non-agricultural;
- whether it had development potential;
- its location in relation to a highway;
- surrounding development;
- comparable transactions;
- the nature of permissible use;
- the existence of structures; and
- other statutory valuation factors.
Therefore, examining the nature of the property is not automatically an impermissible exercise.
The real limitation is different.
The arbitrator cannot use the power to determine compensation as a disguised power to alter the acquisition itself.
The distinction may be expressed simply:
Determining the correct value of the acquired property is within the compensation inquiry. Changing the statutory acquisition itself is not.
The valuation date is the invisible anchor.
One of the easiest ways to misunderstand land-acquisition enhancement is to focus exclusively on the date of the arbitral award.
But the valuation does not ordinarily ask:
“What is this land worth when the arbitrator decides the case?”
The relevant statutory date anchors the inquiry.
That is why subsequent development cannot automatically be treated as evidence of the property’s value at an earlier date.
A highway may have transformed a rural area after acquisition.
Commercial establishments may have emerged.
Residential colonies may have developed.
Land prices may have multiplied.
None of these developments automatically proves that the acquired land possessed the same value on the legally relevant date.
The arbitrator must therefore distinguish between evidence of value and subsequent appreciation.
Does a later enhancement invalidate the original award?
Generally, no.
The existence of a later enhancement does not mean that the original competent authority acted without jurisdiction.
Nor does the enhanced award mean that the acquisition itself was defective.
The statutory framework deliberately allows the initial compensation determination to be challenged.
That is the purpose of Section 3G(5).
The original award and the arbitral award therefore occupy different positions in the statutory process:
The competent authority makes the initial determination.
The arbitrator provides the statutory mechanism for resolving a dispute over that determination.
If the arbitrator finds that the compensation was inadequate and lawfully enhances it, the later award supersedes the earlier determination to the extent of the dispute.
The acquisition, however, remains rooted in the original statutory proceedings.
But what if the original award classified the land incorrectly?
This presents the most difficult version of the problem.
Suppose the competent authority classified the land as agricultural.
The landowner proves before the arbitrator that, even on the relevant acquisition date, the property legally qualified for a different valuation category.
Can the arbitrator correct that error?
There is a strong argument that the arbitrator can do so for the purpose of determining the compensation legally payable, corrected is supported by the governing statute and evidence.
Otherwise, the statutory right to challenge compensation would become meaningless.
An arbitrator who is permitted only to adjust arithmetic but not correct the legal or factual assumptions underlying valuation would have an unnecessarily narrow mandate.
However, the correction must remain connected to the acquisition and valuation date.
The arbitrator cannot use a later change in land use to retroactively create a status that did not exist when the land was acquired.
Arbitration is not a second acquisition proceeding
This is perhaps the clearest conceptual boundary.
The arbitrator does not ask:
Should this land have been acquired?
That question ordinarily belongs to the acquisition process and the statutory remedies available against it.
The arbitrator asks:
Given that the land has been acquired, what compensation is legally payable?
That difference protects the integrity of the acquisition framework.
If every compensation arbitration could reopen the entire acquisition, Section 3G(5) would become an indirect mechanism for challenging the acquisition itself.
That would fundamentally alter the statutory scheme.
Judicial review: Why Section 34 matters
Because Section 3G(6) applies the Arbitration and Conciliation Act, arbitral awards concerning National Highway compensation may be challenged under the framework of that Act.
But judicial review of arbitral awards is intentionally limited.
Courts do not ordinarily sit as appellate valuation authorities simply because another valuation appears possible.
At the same time, an award that ignores mandatory statutory provisions, relies upon legally impermissible methodology, or reaches a conclusion unsupported by the governing framework may attract judicial intervention.
The decision in Alfa Remidis is particularly significant here because the Supreme Court treated disregard of the statutory valuation methodology as capable of constituting patent illegality.
The lesson is therefore two-sided:
Arbitrators have room to determine compensation.
They do not have freedom to disregard the statute governing compensation.
The constitutional dimension: Article 300A
The issue also has a constitutional dimension.
Article 300A provides that no person shall be deprived of property except by authority of law.
Once the State compulsorily acquires private property, compensation becomes an essential part of the statutory framework governing that deprivation.
The constitutional protection does not necessarily guarantee any particular market price.
But it reinforces the requirement that compensation be determined according to the governing law rather than administrative convenience.
This makes arbitral review especially important.
The landowner should not be trapped permanently by an erroneous initial valuation merely because the first authority happened to assign an inadequate amount.
At the same time, the State should not be subjected to arbitrary retrospective increases unsupported by statutory methodology.
The arbitration mechanism therefore has to maintain a difficult equilibrium between fair compensation and legal certainty.
The larger problem: Administrative arbitral appointments
A particularly interesting institutional issue arises because Section 3G(5) arbitrators are often serving government officers.
The Supreme Court and other courts have noted concerns regarding the practical difficulties faced by landowners when compensation disputes involving complex valuation questions are decided within an administrative structure.
A recent Punjab and Haryana High Court decision noted the contrast between the earlier Land Acquisition Act regime—where references were decided by judicial officers—and the National Highways Act mechanism, under which administrative officers are commonly appointed as arbitrators.
This raises an important question:
Can an administrative arbitrator simultaneously protect the statutory interests of the acquisition process and independently adjudicate a compensation dispute against the acquiring authority?
The answer depends upon the safeguards of independence, procedure and judicial review.
But the question itself deserves greater legislative attention.
Original compensation versus later enhancement: What actually changes?
The answer can now be stated more clearly.
When an arbitrator enhances compensation, several things may change:
The amount payable may change.
The valuation methodology may be corrected.
The classification relevant to valuation may, where legally and factually justified, be corrected.
Interest and consequential statutory benefits may change according to the enhanced amount and applicable law.
But several things ordinarily do not change:
The original acquisition notification remains the foundation of the acquisition.
The date of acquisition does not shift merely because compensation is enhanced.
The public purpose does not change.
The identity of the acquired property does not change.
The arbitral award does not ordinarily constitute a fresh acquisition.
This distinction is crucial.
A line that arbitrators should not cross
The law ultimately requires a disciplined distinction between valuation correction and legal transformation.
An arbitrator should be able to say:
“The competent authority valued this land incorrectly; applying the statutory criteria, the correct compensation is higher.”
But the arbitrator should not effectively say:
“The acquisition should now be treated as though it occurred under a different legal regime, on a different factual basis, or with a different statutory character.”
The first is adjudication.
The second risks legislation by arbitration.
Conclusion
The battle between original compensation and later enhancement is not simply a contest between a lower number and a higher number.
It is a contest over institutional boundaries.
The competent authority determines compensation at the initial stage.
The arbitrator provides a statutory mechanism to correct disputed compensation.
The courts supervise the legality of that arbitral determination within the limited framework prescribed by arbitration law.
Within this structure, an arbitrator can correct valuation errors, reconsider relevant evidence and enhance compensation where the law requires it.
But enhancement should not be confused with rewriting the acquisition itself.
The principle emerging from cases such as Union of India v. Parmal Singh is that enhanced compensation relates to the acquisition because it represents the amount that should have been determined in the first place.
At the same time, Sarjuprasad demonstrates that enhancement must rest upon a procedurally fair evidentiary foundation, while Alfa Remidis demonstrates that statutory valuation rules cannot be discarded merely because an alternative valuation appears attractive.
The most defensible position, therefore, is this:
An arbitrator may correct the value of an acquisition, but cannot use compensation arbitration to create a different acquisition.
The distinction may appear subtle, but it is fundamental.
Because when private property is compulsorily taken, fairness demands adequate compensation—but legality determines how that compensation must be calculated.
