Introduction
In a significant judgment on motor accident compensation, the Supreme Court has held that the loss of a right leg above the knee should be treated as 100% functional disability in the case of a mason. The Court clarified that compensation should not be determined solely by the percentage of physical disability certified by medical experts but by the actual impact of the injury on the victim’s ability to earn a livelihood.
Background of the Case
The case involved a mason who suffered a severe road accident, resulting in the amputation of his right leg above the knee. Although the medical board assessed his permanent physical disability at 70%, the Motor Accident Claims Tribunal and the High Court calculated compensation based on the same percentage.
The claimant approached the Supreme Court, arguing that due to the nature of his profession, he could no longer continue working as a mason and had effectively lost his entire earning capacity.
Court’s Key Observation
The Supreme Court observed that:
- Physical disability and functional disability are distinct legal concepts.
- Compensation must reflect the actual loss of earning capacity suffered by the injured person.
- For occupations involving strenuous physical labour, the inability to perform the work may amount to complete functional disability even if the medical disability is lower.
- Courts must assess the effect of the injury on the claimant’s profession rather than mechanically relying on the medical disability percentage.
Functional Disability Depends on the Nature of Employment
The Court explained that a mason’s work requires:
- Standing for prolonged periods.
- Climbing and balancing.
- Lifting heavy construction materials.
- Continuous physical movement.
Since an above-knee amputation makes it practically impossible for a person to continue such physically demanding work, the claimant’s loss of earning capacity was effectively 100%, irrespective of the medical assessment of 70% permanent disability.
Difference Between Physical and Functional Disability
The judgment reiterates an important legal principle:
- Physical disability refers to the medical assessment of bodily impairment.
- Functional disability refers to how that impairment affects a person’s ability to pursue their occupation and earn an income.
The Court emphasized that in motor accident compensation cases, functional disability is often the more relevant consideration when calculating future loss of income.

Enhancement of Compensation
After reassessing the claimant’s functional disability at 100%, the Supreme Court substantially enhanced the compensation payable.
The Court also corrected errors in the calculation of future loss of earnings and increased the amount awarded towards future medical expenses, recognizing that an above-knee amputee would require lifelong medical care, rehabilitation, and periodic replacement of an artificial limb.
Importance of the Ruling
This judgment is significant because it:
- Reinforces that compensation should reflect the actual impact of injuries on earning capacity.
- Distinguishes between medical disability and functional disability.
- Ensures fair compensation for workers engaged in physically demanding occupations.
- Strengthens the rights of accident victims under the Motor Vehicles Act.
Impact on Future Motor Accident Claims
The ruling is expected to guide Motor Accident Claims Tribunals and courts in future cases by emphasizing that:
- Medical disability percentages should not be applied mechanically.
- The claimant’s profession and nature of work must be carefully considered.
- Functional disability may be assessed at 100% where injuries completely prevent a person from continuing their occupation.
This approach promotes a more realistic and equitable assessment of compensation.
Conclusion
The Supreme Court’s decision marks an important development in motor accident compensation law by recognizing that the real measure of disability is its effect on a person’s livelihood. By treating the loss of a right leg above the knee as 100% functional disability for a mason, the Court reaffirmed that compensation must be based on the actual loss of earning capacity and not merely on the percentage of physical impairment certified by medical authorities.
