Apportionment of Liability

1. Meaning

Apportionment of liability means dividing responsibility for a loss, injury, damage, or compensation among two or more persons according to the extent to which each person contributed to the wrongful act or damage.

In Indian tort and motor-accident law, the concept becomes particularly important where more than one person is negligent. The court must first determine whether the case involves:

1. Contributory negligence — the injured person himself contributed to the accident; or
2. Composite negligence — two or more other persons caused the injury, while the injured person was not negligent.

The distinction is crucial because liability can be reduced in contributory negligence, whereas in composite negligence the claimant ordinarily retains the right to recover the entire compensation from any one of the joint tortfeasors.

2. Object of Apportionment

Apportionment seeks to:

• identify the respective responsibility of negligent parties;
• ensure that a person does not bear more than his appropriate share as between wrongdoers;
• reduce compensation where the claimant himself contributed to the loss;
• determine inter se liability between joint tortfeasors;
• prevent injustice where different parties have contributed differently to the damage;
• facilitate recovery of amounts paid by one tortfeasor from another.

However, apportionment does not always mean that the claimant can recover only the percentage attributed to each defendant. This depends upon the nature of negligence.

3. Contributory Negligence

Contributory negligence occurs where the claimant's own negligence contributes to the accident or injury.

Example

Suppose:

• Total compensation = ₹10 lakh
• Driver's negligence = 70%
• Victim's negligence = 30%

The claimant's compensation may ordinarily be reduced by 30%.

Thus:

₹10 lakh − 30% = ₹7 lakh

The claimant can recover ₹7 lakh.

The Supreme Court has explained that where the injured person himself contributed to the accident, damages are reduced proportionately to his negligence.

4. Composite Negligence

Composite negligence occurs when two or more persons independently or jointly act negligently and their combined negligence causes injury to a person who himself is not negligent.

Example

A's car and B's truck collide because both drivers were negligent. C, a passenger in A's car, suffers injuries.

C did not contribute to the accident.

This is composite negligence.

A and B may be jointly and severally liable to C.

C can ordinarily recover the entire compensation from either A or B, subject to the applicable law. The party who pays more than its ultimate share may seek adjustment or contribution from the other tortfeasor.

5. Difference Between Contributory and Composite Negligence

The Supreme Court has repeatedly emphasized this distinction.

6. Joint and Several Liability

Joint and several liability means that where several persons are responsible for the same injury, the injured claimant can proceed against one or more of them for the whole amount of compensation.

For example, if A and B are jointly responsible for ₹20 lakh damage:

• claimant may recover ₹20 lakh from A;
• or ₹20 lakh from B;
• or recover from both in appropriate proportions.

The claimant should not be forced to bear the risk that one wrongdoer is unable to pay.

The Supreme Court in Khenyei v. New India Assurance Co. Ltd. specifically held that, in composite negligence, apportionment of compensation vis-à-vis the claimant is not permissible because the liability of joint tortfeasors is joint and several.

7. Apportionment Between Tortfeasors

There is an important distinction between:

A. Apportionment against the claimant

This is generally not permissible in composite negligence.

The claimant can recover the entire compensation from any joint tortfeasor.

B. Apportionment between tortfeasors

This may be determined where all tortfeasors are before the court and sufficient evidence exists.

For example:

• A = 70% negligence
• B = 30% negligence
• compensation = ₹10 lakh

If A pays the entire ₹10 lakh to the claimant, A may, depending upon the applicable legal principles, seek ₹3 lakh from B as B's inter-se share.

The purpose is to settle the equities between the wrongdoers, not to restrict the claimant's recovery.

8. Factors Considered by Courts

Courts generally consider:

1. Nature of the negligent act

Whether the conduct was rash, careless, reckless, or otherwise unreasonable.

2. Causative contribution

How substantially each person's conduct contributed to the accident.

3. Proximity to the damage

Whether the conduct was a direct or significant cause of the injury.

4. Conduct of the injured person

Whether the claimant took reasonable precautions for his own safety.

5. Surrounding circumstances

Courts examine the complete factual situation rather than applying a mathematical formula.

6. Evidence

Witness testimony, documents, accident reports, medical evidence and surrounding circumstances may be relevant.

The Supreme Court has observed that negligence is a comparative concept and that no mathematically exact formula can be applied in every case; the surrounding circumstances must be considered.

9. Important Case Laws

1. T.O. Anthony v. Karvarnan

(2008) 3 SCC 748

This is one of the leading Supreme Court decisions explaining the difference between contributory and composite negligence.

Principle

The Court explained that:

• composite negligence involves negligence of two or more wrongdoers;
• the injured person is not himself responsible for the accident;
• each wrongdoer can be jointly and severally liable;
• in contributory negligence, the injured person's own negligence contributes to the accident;
• damages payable to the injured person are reduced proportionately.

Importance

This case provides the basic doctrinal framework for determining whether apportionment should affect the claimant's compensation.

2. Khenyei v. New India Assurance Co. Ltd.

(2015) 9 SCC 273

This is perhaps the most important authority on apportionment in composite negligence.

Principle

The Supreme Court held that in a case of composite negligence:

• liability towards the claimant is joint and several;
• the claimant may recover the entire compensation from any one of the joint tortfeasors;
• the claimant cannot be compelled to recover only the percentage attributed to a particular tortfeasor;
• apportionment between tortfeasors may nevertheless be determined for their inter-se liability.

Thus, apportionment is possible for adjustment between wrongdoers but does not ordinarily reduce the claimant's right to recover the entire compensation.

3. Municipal Corporation of Greater Bombay v. Laxman Iyer

(2003) 8 SCC 731

The Supreme Court discussed negligence, contributory negligence and composite negligence.

Principle

The Court recognized that in cases of contributory negligence, courts have the power to apportion the loss between the parties in a manner that is just and equitable.

But where the injured person has not contributed to the accident and the injury results from the combined negligence of two other persons, the matter is one of composite negligence, not contributory negligence.

Importance

This case demonstrates why the court must first correctly classify the type of negligence before deciding whether compensation should be reduced.

4. Pawan Kumar v. Harkishan Dass Mohan Lal

(2014)

The Supreme Court considered an accident involving multiple vehicles and the question whether liability could properly be characterized as contributory or composite negligence.

Principle

Where the claimant is a third party who has not contributed to the accident, the negligence of the different vehicles may constitute composite negligence rather than contributory negligence.

The distinction becomes especially important where one of the negligent vehicles or its driver cannot be brought before the court.

5. New India Assurance Co. Ltd. v. Ashok Kumar Acharya

7 January 1994

The Court examined the distinction between composite and contributory negligence.

Principle

The decision explains that:

• composite negligence involves combined negligence of two or more persons;
• contributory negligence involves negligence by the injured person himself;
• in composite negligence, the wrongdoers may be jointly and severally liable;
• the claimant can proceed against one or more wrongdoers.

The judgment also considered whether liability could be apportioned between tortfeasors for purposes of inter-se adjustment.

6. Sushila Bhadoriya v. Madhya Pradesh State Road Transport Corporation

2004

The Madhya Pradesh High Court considered whether liability between joint tortfeasors could be apportioned.

Principle

The court recognized that in composite negligence the claimant can proceed against either or both tortfeasors because their liability is joint and several.

At the same time, where adequate evidence exists, the court may determine the inter-se liability between the tortfeasors.

Thus, apportionment may have significance between the wrongdoers even though it does not ordinarily restrict the claimant's right to recover compensation.

7. Champa Devi Sharma v. New India Assurance Co. Ltd.

2019

This case reiterated the distinction between composite and contributory negligence.

Principle

Where the claimant himself is negligent, the claim is reduced to the extent attributable to his negligence.

But in composite negligence, where the claimant has not contributed to the accident, the joint tortfeasors remain jointly and severally liable.

The decision expressly relied upon the principles in T.O. Anthony and Khenyei.

8. Recent Supreme Court approach

The Supreme Court has continued to apply apportionment principles where the evidence establishes contributory negligence.

In a 2025 decision, the Court found contributory negligence on the part of both drivers and apportioned liability at 50% each, based upon the particular facts and driving conduct involved.

This illustrates that apportionment is ultimately fact-sensitive and depends on the evidence establishing the respective contribution of the parties.

10. Hypothetical Illustration

Suppose A is driving a car and B is driving a truck.

A drives negligently and contributes 40% to the accident.

B drives negligently and contributes 60%.

C, a passenger, suffers damages of ₹10 lakh.

Situation 1 — C was completely innocent

This is composite negligence.

C may ordinarily claim the entire ₹10 lakh from A or B.

The court may determine:

• A: 40%
• B: 60%

for the purpose of inter-se adjustment.

But A cannot ordinarily tell C:

"I am only 40% liable, so you can recover only ₹4 lakh from me."

That would improperly shift the burden of the other tortfeasor's liability onto the innocent claimant.

Situation 2 — C was also negligent

Suppose C's own negligence is 20%.

Then the case involves contributory negligence.

Total damage = ₹10 lakh.

C's contribution = 20%.

Recoverable compensation:

₹10 lakh × 80% = ₹8 lakh

The compensation is therefore reduced because the claimant himself contributed to the accident.

11. Apportionment in Motor Accident Claims

Apportionment is particularly significant under motor accident litigation.

The court may have to determine:

• negligence of each driver;
• negligence of the claimant;
• whether the case is composite or contributory negligence;
• liability of owners;
• liability of insurers;
• extent of inter-se liability;
• amount of compensation.

However, courts should not mechanically divide compensation merely because two vehicles were involved.

The nature of the claimant's involvement must first be determined.

12. Important Legal Principle

The central rule can be summarized as follows:

If the claimant is negligent, his compensation may be reduced according to his contributory negligence. If the claimant is innocent and the injury is caused by two or more negligent persons, the case is ordinarily one of composite negligence, and the tortfeasors may be jointly and severally liable to the claimant.

This distinction has been consistently emphasized by the Supreme Court.

13. Conclusion

Apportionment of liability is the legal process of determining how responsibility for damage should be distributed among persons whose conduct contributed to the loss.

Its application depends primarily on whether the case involves contributory negligence or composite negligence.

In contributory negligence, the claimant's own fault contributes to the accident, and the compensation is ordinarily reduced proportionately.

In composite negligence, the claimant is innocent but suffers injury because of the combined negligence of two or more persons. The claimant ordinarily has the benefit of joint and several liability and can recover the entire compensation from any one of the responsible tortfeasors. The courts may nevertheless determine the respective shares of the tortfeasors for inter-se adjustment.

Therefore, the modern Indian position can be expressed in one sentence:

Apportionment may determine the ultimate burden between wrongdoers, but in composite negligence it should not ordinarily prejudice the innocent claimant's right to recover the full compensation.
