This is an excerpt from the judgment of ‘Sidram v. Divisional Manager, United India Insurance co. Ltd. (2018)’.

Permanent Disability and Temporary Disability

Disability refers to any restriction or lack of ability to perform an activity in the manner considered normal for a human being.

Permanent disability refers to the residuary incapacity or loss of use of some part of the body, found existing at the end of the period of treatment and recuperation, after achieving the maximum bodily improvement or recovery which is likely to remain for the remainder life of the injured.

Temporary disability refers to the incapacity or loss of use of some part of the body on account of the injury, which will cease to exist at the end of the period of treatment and recuperation.

Permanent Disability

Permanent disability can be either partial or total. Partial permanent disability refers to a person’s inability to perform all the duties and bodily functions that he could perform before the accident, though he is able to perform some of them and is still able to engage in some gainful activity. Total permanent disability refers to a person’s inability to perform any avocation or employment related activities as a result of the accident.

The permanent disabilities that may arise from motor accident injuries, are of a much wider range when compared to the physical disabilities which are enumerated in the Persons with Disabilities (Equal Opportunities, Protection of Rights and Full Participation) Act, 1995 (“the Disabilities Act”, for short). But if any of the disabilities enumerated in Section 2(i) of the Disabilities Act are the result of injuries sustained in a motor accident, they can be permanent disabilities for the purpose of claiming compensation.

The percentage of permanent disability is expressed by the doctors with reference to the whole body, or more often than not, with reference to a particular limb. When a disability certificate states that the injured has suffered permanent disability to an extent of 45% of the left lower limb, it is not the same as 45% permanent disability with reference to the whole body. The extent of disability of a limb (or part of the body) expressed in terms of a percentage of the total functions of that limb, obviously cannot be assumed to be the extent of disability of the whole body.

If there is 60% permanent disability of the right hand and 80% permanent disability of left leg, it does not mean that the extent of permanent disability with reference to the whole body is 140% (that is 80% plus 60%). If different parts of the body have suffered different percentages of disabilities, the sum total thereof expressed in terms of the permanent disability with reference to the whole body cannot obviously exceed 100%.

Where the claimant suffers a permanent disability as a result of injuries, the assessment of compensation under the head of loss of future earnings would depend upon the effect and impact of such permanent disability on his earning capacity. The Tribunal should not mechanically apply the percentage of permanent disability as the percentage of economic loss or loss of earning capacity. In most of the cases, the percentage of economic loss, that is, the percentage of loss of earning capacity, arising from a permanent disability will be different from the percentage of permanent disability.

Some Tribunals wrongly assume that in all cases, a particular extent (percentage) of permanent disability would result in a corresponding loss of earning capacity, and consequently, if the evidence produced show 45% as the permanent disability, will hold that there is 45% loss of future earning capacity. In most of the cases, equating the extent (percentage) of loss of earning capacity to the extent (percentage) of permanent disability will result in award of either too low or too high a compensation.

The effect of permanent disability on the earning capacity of person

What requires to be assessed by the Tribunal is the effect of the permanent disability on the earning capacity of the injured; and after assessing the loss of earning capacity in terms of a percentage of the income, it has to be quantified in terms of money, to arrive at the future loss of earnings (by applying the standard multiplier method used to determine loss of dependency).

The Tribunal has to first decide whether there is any permanent disability and, if so, the extent of such permanent disability. This means that the Tribunal should consider and decide with reference to the evidence:

(i) whether the disablement is permanent or temporary;

(ii) if the disablement is permanent, whether it is permanent total disablement or permanent partial disablement;

(iii) if the disablement percentage is expressed with reference to any specific limb, then the effect of such disablement of the limb on the functioning of the entire body, that is, the permanent disability suffered by the person.

If the Tribunal concludes that there is no permanent disability then there is no question of proceeding further and determining the loss of future earning capacity. But if the Tribunal concludes that there is permanent disability then it will proceed to ascertain its extent. After the Tribunal ascertains the actual extent of permanent disability of the claimant based on the medical evidence, it has to determine whether such permanent disability has affected or will affect his earning capacity.

Ascertainment of the effect of the permanent disability on the actual earning capacity involves three steps.

• The Tribunal has to first ascertain what activities the claimant could carry on in spite of the permanent disability and what he could not do as a result of the permanent disability (this is also relevant for awarding compensation under the head of loss of amenities of life).
• The second step is to ascertain his avocation, profession and nature of work before the accident, as also his age.
• The third step is to find out whether

(i) the claimant is totally disabled from earning any kind of livelihood, or

(ii) whether in spite of the permanent disability, the claimant could still effectively carry on the activities and functions, which he was earlier carrying on, or

(iii) whether he was prevented or restricted from discharging his previous activities and functions, but could carry on some other or lesser scale of activities and functions so that he continues to earn or can continue to earn his livelihood.

For example, if the left hand of a claimant is amputated, the permanent physical or functional disablement may be assessed around 60%. If the claimant was a driver or a carpenter, the actual loss of earning capacity may virtually be hundred per cent, if he is neither able to drive or do carpentry. On the other hand, if the claimant was a clerk in government service, the loss of his left hand may not result in loss of employment and he may still be continued as a clerk as he could perform his clerical functions; and in that event the loss of earning capacity will not be 100% as in the case of a driver or carpenter, nor 60% which is the actual physical disability, but far less.

In fact, there may not be any need to award any compensation under the head of “loss of future earnings”, if the claimant continues in government service, though he may be awarded compensation under the head of loss of amenities as a consequence of losing his hand.

Sometimes the injured claimant may be continued in service, but may not be found suitable for discharging the duties attached to the post or job which he was earlier holding, on account of his disability, and may therefore be shifted to some other suitable but lesser post with lesser emoluments, in which case there should be a limited award under the head of loss of future earning capacity, taking note of the reduced earning capacity.

It may be noted that when compensation is awarded by treating the loss of future earning capacity as 100% (or even anything more than 50%), the need to award compensation separately under the head of loss of amenities or loss of expectation of life may disappear and as a result, only a token or nominal amount may have to be awarded under the head of loss of amenities or loss of expectation of life, as otherwise there may be a duplication in the award of compensation. Be that as it may.

The role of Tribunal

The Tribunal should not be a silent spectator when medical evidence is tendered in regard to the injuries and their effect, in particular, the extent of permanent disability. Sections 168 and 169 of the Act make it evident that the Tribunal does not function as a neutral umpire as in a civil suit, but as an active explorer and seeker of truth who is required to “hold an enquiry into the claim” for determining the “just compensation”. The Tribunal should therefore take an active role to ascertain the true and correct position so that it can assess the “just compensation”.

While dealing with personal injury cases, the Tribunal should preferably equip itself with a medical dictionary and a handbook for evaluation of permanent physical impairment (for example, Manual for Evaluation of Permanent Physical Impairment for Orthopaedic Surgeons, prepared by American Academy of Orthopaedic Surgeons or its Indian equivalent or other authorised texts) for understanding the medical evidence and assessing the physical and functional disability. The Tribunal may also keep in view the First Schedule to the Workmen’s Compensation Act, 1923 which gives some indication about the extent of permanent disability in different types of injuries, in the case of workmen.

If a doctor giving evidence uses technical medical terms, the Tribunal should instruct him to state in addition, in simple non-medical terms, the nature and the effect of the injury. If a doctor gives evidence about the percentage of permanent disability, the Tribunal has to seek clarification as to whether such percentage of disability is the functional disability with reference to the whole body or whether it is only with reference to a limb. If the percentage of permanent disability is stated with reference to a limb, the Tribunal will have to seek the doctor’s opinion as to whether it is possible to deduce the corresponding functional permanent disability with reference to the whole body and, if so, the percentage.

The Tribunal should also act with caution, if it proposed to accept the expert evidence of doctors who did not treat the injured but who give “ready to use” disability certificates, without proper medical assessment. There are several instances of unscrupulous doctors who without treating the injured, readily give liberal disability certificates to help the claimants. But where the disability certificates are given by duly constituted Medical Boards, they may be accepted subject to evidence regarding the genuineness of such certificates.

The Tribunal may invariably make it a point to require the evidence of the doctor who treated the injured or who assessed the permanent disability. Mere production of a disability certificate or discharge certificate will not be proof of the extent of disability stated therein unless the doctor who treated the claimant or who medically examined and assessed the extent of disability of the claimant, is tendered for cross- examination with reference to the certificate. If the Tribunal is not satisfied with the medical evidence produced by the claimant, it can constitute a Medical Board (from a panel maintained by it in consultation with reputed local hospitals/medical colleges) and refer the claimant to such Medical Board for assessment of the disability.

Conclusion

We may now summarise the principles discussed above:

(i) All injuries (or permanent disabilities arising from injuries), do not result in loss of earning capacity.

(ii) The percentage of permanent disability with reference to the whole body of a person, cannot be assumed to be the percentage of loss of earning capacity. To put it differently, the percentage of loss of earning capacity is not the same as the percentage of permanent disability (except in a few cases, where the Tribunal on the basis of evidence, concludes that the percentage of loss of earning capacity is the same as the percentage of permanent disability).

(iii) The doctor who treated an injured claimant or who examined him subsequently to assess the extent of his permanent disability can give evidence only in regard to the extent of permanent disability. The loss of earning capacity is something that will have to be assessed by the Tribunal with reference to the evidence in entirety.

(iv) The same permanent disability may result in different percentages of loss of earning capacity in different persons, depending upon the nature of profession, occupation or job, age, education and other factors.
