1. What is an adhesion contract?

An adhesion contract is a standard-form contract drafted by the party with greater bargaining power, where the weaker party generally has only the choice to:

accept the terms or reject the transaction.

Typical examples include:

• insurance policies;
• bank loan agreements;
• consumer/service agreements;
• telecom agreements;
• employment contracts;
• online terms and conditions;
• standard government tender contracts;
• transportation agreements.

The Supreme Court has recognised that an adhesion contract is essentially one where the weaker party has no realistic opportunity to negotiate the terms. Importantly, however, the Court has also made clear that not every adhesion or standard-form contract is unconscionable.

Thus:

Adhesion contract ≠ automatically unconscionable contract ≠ automatically invalid arbitration clause.

That distinction is fundamental.

2. The basic rule: an arbitration clause in a standard-form contract can be valid

Section 7 of the Arbitration and Conciliation Act, 1996 requires an arbitration agreement, among other things, to be an agreement by the parties to submit disputes to arbitration.

The fact that the arbitration clause appears in:

• pre-printed conditions,
• a standard form,
• terms and conditions printed on the reverse,
• online terms,
• purchase-order conditions,

does not by itself destroy consent.

The Supreme Court has repeatedly upheld arbitration agreements incorporated through standard contractual terms.

Inox Wind Ltd. v. Thermocables Ltd.

(2018) 2 SCC 519

This is one of the most important cases on standard-form arbitration clauses.

The Supreme Court held that a general reference to a consensual standard form of contract can be sufficient to incorporate an arbitration clause.

The Court expressly modified the earlier approach in M.R. Engineers, holding that a general reference to a standard form of one contracting party, as well as standard forms of trade associations and professional bodies, can incorporate the arbitration clause.

Therefore, where:

1. A sends a purchase order;
2. the purchase order states that the transaction is governed by A's standard terms;
3. those standard terms contain an arbitration clause; and
4. B accepts the transaction,

the arbitration clause may become part of the contract.

3. But there must still be consent

The most important counter-principle is that arbitration is founded on consent.

A party cannot ordinarily be compelled to arbitrate merely because the other party has unilaterally printed an arbitration clause somewhere.

The court therefore asks:

Was the arbitration clause actually incorporated into the contract?

This becomes particularly important where:

• the clause is in another document;
• the standard terms were never supplied;
• the contract merely refers generally to another agreement;
• the arbitration clause is hidden or obscure;
• the parties executed different documents containing inconsistent terms.

4. Incorporation by reference — M.R. Engineers

M.R. Engineers & Contractors (P) Ltd. v. Som Datt Builders Ltd.

(2009) 7 SCC 696

The Supreme Court considered incorporation of an arbitration clause contained in another document.

The basic principle was that a mere general reference to another contract ordinarily does not automatically incorporate its arbitration clause.

The contract should demonstrate an intention to incorporate the arbitration provision.

The case established an important distinction between:

A. Reference to another contract

and

B. Reference to standard contractual terms

That distinction was subsequently developed by the Supreme Court in Inox Wind.

5. The present position after Inox Wind

The law can be broadly understood as follows:

The Supreme Court has continued to apply this distinction.

The 2026 Supreme Court decision in Kanta Devi reiterated the principles governing incorporation by reference, including the distinction between standard forms and other contracts.

Similarly, the Supreme Court's 2026 jurisprudence confirms that in a two-contract case, a general reference to the earlier contract ordinarily does not automatically incorporate its arbitration clause.

6. Does "take it or leave it" invalidate the arbitration clause?

No, not automatically.

This is perhaps the most common misconception.

The fact that:

"You either sign this contract or you do not get the service"

does not, by itself, mean that the arbitration clause is void.

Modern commerce necessarily involves numerous standard-form contracts.

The Supreme Court has expressly recognised that not every standard-form/adhesion contract is unconscionable.

The court instead examines the circumstances and substance of the bargain.

7. Central Inland Water Transport — the leading unconscionability case

Central Inland Water Transport Corporation Ltd. v. Brojo Nath Ganguly

(1986) 3 SCC 156

This is the leading Indian authority on unconscionable standard-form contracts.

The Supreme Court recognised that where there is a substantial inequality of bargaining power, a stronger party may impose terms upon a weaker party that are so unfair or unreasonable that they cannot be enforced.

The Court particularly examined a standard employment contract imposed by a State-controlled corporation.

The important principle is:

A contractual term may be struck down where it is unconscionable, unreasonable and opposed to public policy, particularly where the parties have grossly unequal bargaining power.

The Supreme Court's later decisions continue to recognise this principle.

But there is an important limitation

Central Inland Water Transport cannot simply be read as:

"Every standard-form arbitration clause is unconstitutional."

That would be incorrect.

The case arose in the context of a State instrumentality and Article 14/public policy considerations, particularly an oppressive employment condition.

A private commercial contract between sophisticated parties presents a different question.

The Delhi High Court, for example, has correctly observed that merely finding an arbitration clause in a standard-form contract does not make it unconscionable; the reasoning of Central Inland Water Transport must be applied in its proper factual and constitutional context.

8. D.C.M. Ltd. v. Assistant Engineer

D.C.M. Ltd. v. Assistant Engineer

(1987)

The Supreme Court subsequently considered the principles of Central Inland Water Transport in the context of a standard-form arrangement.

It recognised that an unconscionable term in a contract with a State entity may be invalid where it violates Article 14.

The Court also explained the concept of adhesion contracts and the relevance of absence of meaningful choice.

This is important because it shows that the issue is not simply:

"Was the contract printed in a standard form?"

Instead, the inquiry is:

Was the weaker party effectively deprived of meaningful choice, and is the particular contractual term so unfair or unreasonable that the law should refuse enforcement?

9. LIC v. Consumer Education & Research Centre

LIC of India v. Consumer Education & Research Centre

(1995) 5 SCC 482

The Supreme Court developed the doctrine of unequal bargaining power in contracts involving State/public authorities.

The Court emphasised that contractual freedom cannot be treated as completely absolute where one party has overwhelming economic power and the other has no meaningful alternative.

This is particularly significant for:

• insurance contracts;
• public-sector contracts;
• employment contracts;
• public utilities;
• essential services.

The principle can be relevant to an arbitration clause where the clause is part of a wider oppressive contractual arrangement.

10. The distinction between "unfair contract" and "unfair arbitration clause"

This distinction is crucial.

Suppose a bank loan agreement contains:

"Any dispute shall be referred to arbitration."

The fact that the loan agreement is a standard-form contract does not make the arbitration clause invalid.

But imagine the same agreement says:

"The borrower must deposit 50% of the disputed amount before he can invoke arbitration."

That is a very different issue.

The second provision may operate as a barrier to accessing arbitration.

This takes us to ICOMM Tele and Lombardi Engineering.

11. ICOMM Tele Ltd. v. Punjab State Water Supply & Sewerage Board

ICOMM Tele Ltd. v. Punjab State Water Supply & Sewerage Board

(2019) 4 SCC 401

This is an extremely important arbitration-clause validity case.

The contract required the party invoking arbitration to deposit 10% of the amount claimed.

The Supreme Court struck down the requirement.

Why?

Because the condition:

• deterred parties from invoking arbitration;
• was excessive and disproportionate;
• made access to arbitration unnecessarily expensive;
• was arbitrary in the circumstances of a State contract.

The Supreme Court subsequently summarised ICOMM Tele by explaining that a contractual term may be arbitrary when it is unfair and unjust, and that a 10% pre-deposit requirement defeated the purpose of arbitration.

Principle

An arbitration clause cannot be used as a mechanism to discourage or practically prevent the weaker party from invoking arbitration.

12. Lombardi Engineering Ltd. v. Uttarakhand Jal Vidyut Nigam Ltd.

Lombardi Engineering Ltd. v. Uttarakhand Jal Vidyut Nigam Ltd.

(2023) 2 SCC 201

The Supreme Court considered another contractual pre-deposit requirement.

The contract required the party initiating arbitration to deposit 7% of the arbitration claim.

The Supreme Court held the provision invalid.

The decision is particularly important because it demonstrates that even though the parties agreed to the contract, party autonomy has limits.

In later Supreme Court jurisprudence, Lombardi has been cited for the proposition that contractual terms in State/public contracts must satisfy constitutional standards and cannot arbitrarily burden access to arbitration.

13. Party autonomy is important—but not unlimited

Indian arbitration law strongly respects party autonomy.

Normally, parties are free to determine:

• whether to arbitrate;
• number of arbitrators;
• procedure;
• seat/place of arbitration;
• governing law;
• institutional or ad hoc arbitration;
• scope of disputes.

But party autonomy is not absolute.

The Supreme Court has expressly recognised that an arbitration agreement must operate within the broader legal framework, including the Constitution, the Arbitration Act and other applicable law.

Therefore:

"I signed it" is not necessarily the end of the legal inquiry.

14. What makes an adhesion arbitration clause vulnerable?

An arbitration clause in a standard-form contract is particularly vulnerable where several of the following factors exist:

1. Extreme inequality of bargaining power

For example:

• individual consumer vs multinational corporation;
• employee vs powerful employer;
• small contractor vs State corporation;
• individual borrower vs large financial institution.

2. No meaningful alternative

If the weaker party cannot reasonably obtain the essential service elsewhere, the argument becomes stronger.

3. Hidden arbitration clause

For example, an arbitration clause buried in extremely lengthy terms without adequate notice.

4. No incorporation

The standard terms containing arbitration were never supplied or properly incorporated.

5. One-sided arbitration mechanism

For example, one party has unilateral control over appointment of the arbitrator.

This is governed by additional jurisprudence such as TRF Ltd. v. Energo Engineering Projects Ltd. and Perkins Eastman Architects DPC v. HSCC (India) Ltd.

6. Excessive financial barrier

For example:

• 10% pre-deposit;
• 50% deposit;
• prohibitively high arbitration costs imposed exclusively on one side.

7. Unreasonable limitation of remedies

A clause may be problematic if it effectively destroys substantive legal rights.

8. Constitutional/public-policy problems

Particularly where a State instrumentality is involved.

15. Standard-form contract alone is NOT enough

Consider two examples.

Example A — likely valid

A large manufacturing company enters into a purchase contract with another established commercial company.

The purchase order says:

"This purchase is subject to the attached Standard Terms and Conditions."

The standard terms clearly contain:

"All disputes arising out of this contract shall be resolved by arbitration."

Both companies routinely use these terms.

This is very likely to constitute a valid arbitration agreement.

Inox Wind strongly supports such incorporation.

Example B — potentially problematic

An individual consumer receives a 40-page agreement for an essential service.

The arbitration provision is buried in small print, requires arbitration at a distant location, imposes extremely high costs on the consumer, and effectively prevents the consumer from pursuing the claim.

Here, simply saying:

"But the consumer signed the agreement"

may not dispose of the challenge.

The court may examine:

• bargaining power;
• meaningful choice;
• notice;
• transparency;
• proportionality;
• financial burden;
• public policy;
• statutory consumer protections.

16. Adhesion contract and Section 7 of the Arbitration Act

Section 7 is fundamental.

An arbitration agreement must demonstrate the parties' agreement to submit disputes to arbitration.

The Supreme Court's contemporary approach places considerable emphasis on existence of the arbitration agreement.

At the Section 11 stage, the court's inquiry is now generally confined to a prima facie determination of the existence of the arbitration agreement. The Supreme Court reiterated this position in 2026.

The Supreme Court has also explained that the Section 11 inquiry is limited and should not become a detailed trial regarding every possible issue concerning the arbitration agreement.

Therefore, a party challenging an adhesion arbitration clause should distinguish between:

"There is no arbitration agreement"

and

"The arbitration agreement exists but is legally unenforceable."

Those are analytically different arguments.

17. Separability of the arbitration agreement

Another important principle is severability.

The arbitration clause is treated as legally distinct from the underlying contract.

Therefore:

Even if the main contract is challenged, the arbitration clause does not automatically disappear.

This is reflected in Section 16 of the Arbitration and Conciliation Act.

Consequently, saying:

"The main contract is void, therefore the arbitration clause is automatically void"

is generally incorrect.

The challenge must be directed appropriately at the arbitration agreement itself or at the legal enforceability of the relevant contractual term.

18. Arbitration clause incorporated from another document

This issue frequently arises in standard-form contracts.

Suppose Contract A says:

"The terms of Contract B shall apply."

Contract B contains an arbitration clause.

Does Contract A automatically contain the arbitration clause?

Generally, not always.

The answer depends upon the nature of the reference.

The Supreme Court distinguishes between:

Single-contract case

A contract incorporates a standard set of terms.

A general reference can be sufficient.

Two-contract case

The parties enter into a new contract and merely refer to an earlier/different contract.

A mere general reference will generally not automatically import the arbitration clause.

The Supreme Court's recent jurisprudence continues to maintain this distinction.

19. Inox Wind — practical test

The Inox Wind approach can be reduced to this practical question:

Did the contractual language demonstrate that the parties intended the standard terms containing the arbitration clause to govern their relationship?

If yes, incorporation is much easier to establish.

If the clause exists in a completely separate contract involving different parties, courts apply a stricter approach.

20. Arbitration clauses imposed by government bodies

This is a particularly important category.

Where one party is:

• Union Government;
• State Government;
• public-sector undertaking;
• statutory corporation;
• State instrumentality,

Article 14 may become relevant.

The government cannot hide behind "freedom of contract" to justify arbitrary contractual conditions.

This is where Central Inland, ICOMM Tele, and Lombardi become particularly important.

The Supreme Court has reiterated that State action in contractual matters must comply with constitutional standards of fairness, reasonableness and non-arbitrariness.

21. Does Article 14 apply to private contracts?

This requires considerable caution.

Central Inland Water Transport is sometimes cited too broadly.

Article 14 is principally a constraint on State action.

Therefore, the argument:

"This private company's standard-form arbitration clause violates Article 14"

is not automatically sustainable merely because the contract is unfair.

For purely private contracts, the challenge ordinarily needs to be founded on applicable principles such as:

• Contract Act;
• public policy;
• unconscionability where legally recognised;
• statutory prohibition;
• absence of consent;
• fraud/misrepresentation;
• undue influence;
• illegality;
• impossibility or other applicable contractual doctrines.

Accordingly, one should identify who the stronger contracting party is before relying on Central Inland.

22. Consumer contracts

Consumer agreements deserve separate treatment.

An arbitration clause does not necessarily eliminate statutory consumer remedies merely because the consumer signed an agreement.

Indian consumer law contains a specific statutory framework, and the Supreme Court has repeatedly considered the relationship between arbitration agreements and statutory remedies.

The analysis can therefore differ depending on:

• when the transaction occurred;
• the applicable Consumer Protection legislation;
• nature of the dispute;
• statutory remedy involved;
• whether the dispute is arbitrable.

Thus, in a consumer dispute, the argument should not be reduced merely to:

"The contract is an adhesion contract."

The statutory framework must also be examined.

23. Employment contracts

Employment agreements are another sensitive category.

A standard employment agreement containing arbitration is not automatically void merely because the employee had no opportunity to negotiate it.

But the court may scrutinise:

• unequal bargaining power;
• statutory employment rights;
• public employment;
• mandatory labour legislation;
• nature of the dispute;
• whether the particular dispute is capable of arbitration.

If the employer is a State instrumentality, Central Inland and Article 14 considerations can become especially important.

24. Unilateral appointment clauses

There is a related but distinct issue.

Suppose an adhesion contract says:

"The employer shall appoint the sole arbitrator."

The problem is not necessarily that the contract is standard-form.

The problem is arbitral impartiality and independence.

The Supreme Court's decisions in:

TRF Ltd. v. Energo Engineering Projects Ltd.

(2017) 8 SCC 377

and

Perkins Eastman Architects DPC v. HSCC (India) Ltd.

(2020) 20 SCC 760

establish important limitations on unilateral appointment mechanisms.

Thus, an adhesion contract can contain an otherwise valid agreement to arbitrate while the appointment mechanism itself is invalid.

That distinction is extremely important.

25. The doctrine of severability can save the arbitration agreement

Suppose a standard-form contract contains:

"All disputes shall be arbitrated."

But its appointment provision says:

"The Managing Director of Company X shall be the sole arbitrator."

The second provision may be legally defective.

That does not necessarily mean:

"There is no arbitration agreement at all."

The court may separate the valid commitment to arbitrate from an invalid appointment mechanism, depending on the wording and applicable law.

26. The court's approach: a useful four-stage test

For an adhesion arbitration clause, I would analyse validity in this sequence:

Stage 1 — Was there an arbitration agreement?

Examine Section 7.

Ask:

• Was there assent?
• Was the clause incorporated?
• Was the standard form part of the contract?
• Were the terms supplied or accessible?
• Was there a reference sufficient to incorporate them?

Stage 2 — Is the clause sufficiently certain?

Ask whether the clause identifies:

• arbitration as the dispute-resolution mechanism;
• the relevant disputes;
• the parties;
• the contractual relationship.

An arbitration clause should manifest an intention to arbitrate.

Stage 3 — Is the arbitration agreement legally enforceable?

Examine:

• Arbitration Act;
• Contract Act;
• statutory prohibitions;
• public policy;
• arbitrability;
• constitutional limitations where applicable.

Stage 4 — Is the particular arbitration mechanism valid?

Examine:

• unilateral appointment;
• excessive pre-deposit;
• unreasonable costs;
• oppressive venue;
• procedural barriers;
• conflict of interest;
• denial of equal treatment.

This final stage is where ICOMM Tele, Lombardi, TRF and Perkins become particularly useful.

27. Key case-law matrix

The recent Supreme Court cases reinforce that consent and existence of an arbitration agreement remain foundational, while questions going beyond the limited Section 11 inquiry may be left to the arbitral tribunal where appropriate.

28. The most important legal proposition

The correct proposition is not:

"An arbitration clause in an adhesion contract is invalid."

Nor is it:

"A signed adhesion contract is always binding."

The more accurate rule is:

An arbitration clause contained in a standard-form or adhesion contract is prima facie capable of being valid and enforceable, provided that the clause has been properly incorporated and satisfies Section 7 of the Arbitration and Conciliation Act, 1996. The mere absence of negotiation does not invalidate it. However, where the weaker party lacked meaningful choice and the arbitration provision or associated contractual mechanism is unconscionable, arbitrary, oppressive, statutorily prohibited, or otherwise contrary to public policy, the court may refuse to enforce the provision or may sever an invalid component.

That is the position that best reconciles Central Inland Water Transport, M.R. Engineers, Inox Wind, ICOMM Tele, Lombardi, and the more recent Supreme Court arbitration jurisprudence.

29. A useful argument for challenging an adhesion arbitration clause

If you are challenging such a clause, the strongest pleading would generally not be:

"It is a standard-form contract, therefore the arbitration clause is invalid."

Instead, build the argument cumulatively:

1. No genuine consent to arbitration;
2. arbitration clause was not properly incorporated;
3. standard terms were not supplied/made available;
4. there was gross inequality of bargaining power;
5. the weaker party had no realistic alternative;
6. the clause is unusually onerous or hidden;
7. the mechanism imposes a disproportionate financial/procedural burden;
8. the clause contains a prohibited unilateral appointment mechanism;
9. the clause defeats access to the arbitral process;
10. the relevant party is a State instrumentality, attracting Article 14 scrutiny;
11. the clause conflicts with a mandatory statutory remedy;
12. consequently, the particular clause/condition is unenforceable even if the underlying contract otherwise exists.

That is substantially stronger than relying on the label "adhesion contract" alone.

30. Conversely, the defence of the arbitration clause

The party seeking to enforce it would argue:

1. standard-form contracts are legally recognised;
2. adhesion does not equal unconscionability;
3. the contract was voluntarily accepted;
4. the arbitration clause was clearly incorporated;
5. the terms were available to the other party;
6. the parties had a commercial relationship;
7. the parties are commercially sophisticated;
8. there is no statutory prohibition;
9. the arbitration procedure is mutually applicable;
10. there is no excessive financial barrier;
11. the appointment mechanism is independent and legally valid;
12. there is no violation of public policy.

Inox Wind is particularly useful for establishing incorporation of standard terms, while Central Inland should be distinguished where the parties have relatively equal bargaining power.

Bottom line

An arbitration clause in an adhesion contract is not per se void in India.

The decisive questions are consent + incorporation + statutory validity + fairness of the particular mechanism, rather than simply whether the contract was presented on a "take-it-or-leave-it" basis.

For a private commercial contract between sophisticated parties, courts are generally much less receptive to an argument that the arbitration clause is invalid merely because it was contained in standard terms.

For a consumer, employee, small contractor, borrower, or party dealing with a State instrumentality, a serious challenge may arise where there is gross inequality of bargaining power combined with an oppressive or disproportionate arbitration mechanism. Central Inland, ICOMM Tele and Lombardi become particularly important in that situation.
