The principle of reprisal asserts that on the passing of a loss the insured shall be put back into the same fiscal position as he used to enthrall incontinently before the loss.
In other words, the ensured shall get neither further nor lower than the factual quantum of loss sustained.
This, of course, is always subject to the limit of the sum ensured and also subject to certain terms and conditions of the policy.
Therefore, to put it in a much better way, on the happening of a loss, the insurers will try to put back the insured into the same financial position as the insured used to occupy immediately before the happening of the loss, only if the insurance is properly arranged on full value insurance.
Under-insurance and restrictive terms of the policy may preclude the insured from getting the actual loss.
On the other hand, even if the sum insured is more than the actual value of the property or subject matter; this would not entitle the insured to get more than the actual loss.
This principle is indeed very important to keep the business of insurance on track and to keep it free from wagering.
This also checks the moral hazard of a man and at the same time allows him to get the actual amount of loss and certainly not more than that.
Consider a proposition wherein through over-insurance somebody is allowed to take more than the actual amount of loss.
Well, in that case, it can be said with definite certainty that there will always be a temptation to create an insured event deliberately for the sole purpose of making a profit out of a loss.
The principle of indemnity was well cared for in the leading case of Castellain V. Preston (1883) in the following way “A contract of insurance is necessarily a contract of indemnity (except life and personal accident insurance) and of indemnity only, and this means that in case of a loss the insured shall be fully indemnified, but shall never be more than fully indemnified.
That is the fundamental principle of insurance and if ever a proposition is brought forward, which is at variance with it, that is to say, which either will prevent the insured from obtaining a full indemnity or which will give the insured more than a full indemnity, that proposition must certainly be wrong”.
In a contract of reprisal, the selection of proper sum ensured is important as this is always the limit within which reprisal will be considered.
thus, if the sum ensured is confined to a lower quantum than the factual value also in the case of a total loss the insured gets the sum ensured which doesn't compensate him.
Indeed if it isn't a total loss, nonetheless, using a policy condition known as ’ average ’ the insurers won't pay further than the commensurate loss, i.e., corresponding the rate between sum- ensured and factual value.( Average bandied latterly on).
Also, there's also no point in arranging an inordinate sum- ensured as that will noway entitle him to get further than the factual quantum of loss as formerly explained.
This will simply mean the payment of inordinate decoration without any matching benefit. Sum- ensured should, thus, always base on the factual request value of the subject matter of insurance at the time of effecting the policy of insurance.
The essential demand of insurance is that it should be full value insurance.
