Standardised Prosthetic-Limb Compensation in Motor Accident Claims: 5-Year Replacement Cycles up to Age 70, Reasonableness Test, and Rejection of Government Rate Caps

1. Introduction

Prahlad Sahai v. Haryana Roadways & Anr. (2026 INSC 396, decided on 21-04-2026) concerns the computation of compensation in a motor accident claim where the claimant suffered amputation of the right leg below the knee. The accident occurred on 02.05.2007 when a Haryana Roadways bus hit the motorcycle the appellant was riding on from behind, causing crushing injuries and eventual amputation (noted as having occurred on 17.07.2009).

The Motor Accident Claims Tribunal awarded Rs. 8,73,211, which the Rajasthan High Court enhanced to Rs. 13,02,043 under various heads but awarded nothing for a prosthetic limb. Before the Supreme Court, the central issue was the jurisprudential basis and method to compute “just compensation” for prosthetic limb purchase and maintenance, and whether further enhancement was due on income and disability.

2. Summary of the Judgment

The Supreme Court allowed the appeal and granted substantial enhancement, principally by:

  • Recognising prosthetic-limb costs as an essential component of restitutio in integrum and awarding compensation for periodic replacement and maintenance.
  • Reiterating a standard approach: replacement every 5 years and computation up to an assumed life span of 70 years.
  • Rejecting reliance on the Government notification rates (Rs. 20,000–25,000) as “abysmally low” and holding that courts are not bound by them where the claimant’s reasonable needs require higher sums.
  • Enhancing income assessment to Rs. 6,000/month (despite lack of documentary proof), treating the appellant’s functional disability as 100% for a heavy-vehicle driver, and applying 40% future prospects and multiplier 16.
  • Awarding litigation costs.

The Court directed the insurer (Respondent No.2) to pay Rs. 36,20,350 (rounded) over and above the High Court award, within four weeks, failing which interest @ 9% per annum would apply.

3. Analysis

3.1 Precedents Cited (and their Influence)

(A) “Just compensation” and avoidance of windfall/pittance

The Court anchored the entire analysis in Section 168 of the Motor Vehicles Act, 1988 (“just compensation”), relying on State Of Haryana And Another v. Jasbir Kaur And Others, which emphasises: compensation is neither “a windfall” nor “a pittance,” but a fair, reasoned, non-arbitrary assessment. The reference to Helen C. Rebello v. Maharashtra SRTC (quoted within Jasbir Kaur) reinforces that “just” entails equitability and rationality.

(B) Assumed lifespan of 70 years

For projecting future prosthetic needs, the Court relied on Hardeo Kaur v. Rajasthan State Transport Corpn. (which cites Jyotsna Dey v. State Of Assam) to justify taking 70 years as a conservative assumed lifespan in modern conditions. This directly supported the “up to 70 years” standardisation adopted in the prosthetic-limb computation.

(C) Prosthetic limb compensation: replacement and maintenance as long-term necessities

The Court treated MOHD. SABEER @ SHABIR HUSSAIN v. REGIONAL MANAGER, U.P. STATE ROAD TRANSPORT CORPORATION as a key domestic benchmark: it recognised that prosthetic limbs require replacement after a few years and awarded both acquisition and maintenance, assuming life up to 70.

The Court also relied strongly on its more recent pronouncement in Chandra Mogera v. Santosh A. Ganachari & Anr. for two propositions:

  1. A prosthetic limb “usually requires replacement once every 5 years” and computation may reasonably proceed on that basis until age 70.
  2. A procedural standard: henceforth, a prosthetic-limb claim should be accompanied by quotations from at least two or three service providers—reiterated and affirmed in the present decision.

(D) The “reasonableness” test and claimant’s choice (including private procurement)

The Court drew on comparative tort jurisprudence to articulate the measure of reasonableness in assistive-device damages:

  • David Pinnington v. Crossleigh (Lord Brooke’s observations) was used both to highlight the intensely personal nature of prosthetics and to support the proposition that it can be reasonable for a claimant to obtain devices privately and replace them periodically (the judgment notes five-year renewal as reasonable in that case).
  • A (suing by her litigation friend Mrs H) v. Powys Local Health Board was relied upon for the principle that if the claimant’s proposed treatment/equipment is reasonable, the defendant cannot defeat it merely by pointing to cheaper options. Within that discussion, the Court also referenced Rialis v Mitchell, Sowden v Lodge, Massey v Tameside and Glossop Acute Services NHS Trust, and Taylor v Chesworth and MIВ as authorities extending the reasonableness framework from care regimes to aids/equipment.
  • Kerry Donnelly v. Fas Products Ltd was used to explicitly connect prosthetic provision with the compensatory objective of restitutio in integrum, including recognition of replacement costs over the claimant’s life, subject to reasonableness.

This comparative line of authority materially influenced the Court’s rejection of a “lowest-cost” approach and its refusal to treat governmental schedule rates as determinative.

(E) Income assessment without strict documentary proof; future prospects; multiplier

For income determination, the Court accepted Rs. 6,000/month notwithstanding the absence of documents, relying on the pragmatic approach in Ramachandrappa v. Manager, Royal Sundaram Alliance Insurance Company Limited and Syed Sadiq and others v. Divisional Manager, United India Insurance Company Limited, and also noting Chandra and Another v. Mukesh Kumar Yadav and others. For future prospects and structured computation, it applied National Insurance Company Limited v. Pranay Sethi and Others (40% future prospects) and Smt. Sarla Verma & Others v. Delhi Transport Corporation & Another (multiplier 16).

(F) Conceptual framework for personal-injury damages

The Court cited Jai Bhagwan v. Laxman Singh, which in turn references H. West & Son, Ltd. v. Shephard and Admiralty Comrs. v. Susquehanna (Owners), The Susquehanna, to explain the inherent limits of monetising bodily injury and the need for uniform, moderate, comparable awards—while still aiming at financial restoration for pecuniary losses.

3.2 Legal Reasoning

  1. Prosthetic limb as a compensable necessity (pecuniary loss): The Court treated prosthetics not as a discretionary comfort but as an instrument that restores mobility and dignity—squarely within “just compensation” under Section 168 and within the restorative ambition of restitutio in integrum.
  2. Standardised assumptions to reduce arbitrariness: Noting wide variability in awards, the Court adopted standards already emerging from its own jurisprudence: (i) replacement cycle of five years, (ii) assumed lifespan of 70 years.
  3. Number of prosthetic limbs required: With the appellant being 32 years old in 2007, and computing entitlement up to 70 years with a 5-year cycle, the Court held he would need seven prosthetic limbs (correcting the claimant’s suggested eight, also noting the amputation date in 2009).
  4. Quantum and structure of payment: The Court awarded a consolidated amount of Rs. 3,00,000 per limb for seven limbs (Rs. 21,00,000) and separately awarded maintenance at Rs. 15,000 per annum—consolidated as Rs. 5,00,000. Because it awarded a consolidated sum, it declined interest from the accident date for this head.
  5. Government notification rates rejected: The insurer’s reliance on a Government notification suggesting Rs. 20,000–25,000 was rejected as “abysmally low,” with the Court holding that the legally relevant inquiry is the claimant’s reasonable requirement, not a rate card that would defeat restoration.
  6. Functional disability and loss of earning capacity: Based on medical evidence (AW-2) that the appellant could not drive heavy vehicles, the Court treated functional disability as 100% (even if physical disability might be expressed differently), and computed future income loss using Rs. 6,000/month, 40% future prospects, 12 months, multiplier 16, arriving at Rs. 16,12,800, enhancing the High Court figure accordingly.
  7. Litigation costs: A consolidated Rs. 2,00,000 was awarded, signalling judicial recognition that access-to-justice costs in long-running motor accident litigation are real and compensable where appropriate.

3.3 Impact

  • Standardisation with flexibility: By reaffirming “5-year replacement” and “up to 70 years” as a workable standard, the Court provides Tribunals a predictable framework—while still tethering the award to reasonableness and case facts.
  • Rejection of rate-cap defences: The explicit refusal to be bound by governmental schedule rates (where inadequate) will likely curb insurer arguments that attempt to compress prosthetic awards into low administrative price bands.
  • Evidence discipline via quotations: The reiterated direction from Chandra Mogera v. Santosh A. Ganachari & Anr. (quotations from 2–3 providers) promotes more evidence-based awards and may reduce the variance the Court itself noted.
  • Functional disability emphasis: The case reinforces that disability in motor accident law is primarily about loss of earning capacity; for occupation-specific claimants (drivers, manual labourers), courts may treat disability as 100% even if the medical percentage is lower.
  • Likely downstream effects: Tribunals and High Courts may increasingly (i) create distinct prosthetic heads (purchase, replacement, maintenance), (ii) prefer consolidated present-value awards, and (iii) scrutinise reasonableness rather than cheapest-available options.

4. Complex Concepts Simplified

“Just compensation” (Section 168, Motor Vehicles Act, 1988)
The amount must be fair—neither a token amount nor an excessive “windfall”—and must be determined rationally on the claimant’s real losses.
Restitutio in integrum
A damages principle aiming (as far as money can) to restore the injured person to the position they were in before the wrong. For amputees, that includes realistic provision for prosthetics and their upkeep.
Functional disability vs. medical disability
Medical disability describes bodily impairment; functional disability measures how the injury affects the person’s ability to earn in their occupation. A driver losing a leg may be treated as 100% functionally disabled.
Multiplier method
A standard way to compute future loss of earnings: annual loss × a “multiplier” (based on age) to reflect the number of earning years.
Future prospects
An added percentage reflecting likely growth in income over time (here, 40% as per Pranay Sethi).
Reasonableness test (aids/equipment)
If what the claimant seeks is reasonable for their needs, the defendant cannot deny it merely by pointing to a cheaper alternative that might also work.

5. Conclusion

Prahlad Sahai v. Haryana Roadways consolidates a practical, claimant-centred rule for prosthetic-limb compensation in motor accident claims: courts may assume a lifespan of 70 years, treat prosthetics as requiring replacement every 5 years, award both purchase/replacement and maintenance, and decide quantum by reasonableness rather than by low governmental schedule rates. It also strengthens the evidentiary architecture by reaffirming that prosthetic claims should be supported by 2–3 provider quotations.

Beyond prosthetics, the judgment underscores two enduring themes in motor accident jurisprudence: (i) income and livelihood losses must be assessed realistically even in the informal economy, and (ii) disability must be assessed functionally with reference to the claimant’s occupation. Together, these holdings push adjudication closer to genuine restoration rather than nominal compensation.
