Case: Oriental Insurance Co. Ltd Vs. Mantora Oil Products Pvt. Ltd

1. The respondent Company dealt in oil products and for that purpose, it used to purchase vegetable and refined oil from different parts of the country and transported the same in oil tankers. In order to protect itself against losses due to accidents, theft, pilferage, non delivery etc., occurring in the course of transit, the respondent took insurance policies with the appellant in January 1988. The first policy was for an insurance cover of Rs 10,10,00,000 which was further increased by Rs 7 crores. Thus the total insurance coverage was for Rs 17.10 crores for which an aggregate premium of Rs 4,26,826 was paid by the respondent to the appellant.2. One of the conditions of the contract of insurance was that in respect of the unutilised portion of the coverage, the appellant would refund to the respondent the proportionate amount of premium. That is to say, if the value of the total quantity of oil transported fell short of Rs 17.10 crores during the period of policy, the appellant would refund to the respondent the proportionate premium on the amount of shortfall in the quantity transported.

Reasoning: 5. If it was a mistake, the same should have been pointed out to the respondent during the period of the policy but the appellant did not raise this objection at any time during the continuance of the policy cover. The respondent also fulfilled its obligations under the policy and paid the premium as was agreed to between the parties. If there was a mistake on the part of the appellant in collecting the premium, the same should have been pointed out at the time of entering into the contract or immediately thereafter. After having received the benefit under the policy of insurance from the respondent by way of premium, it is not open to the appellant to contend that there was a mistake on their part in charging the premium at a rate lower than the rate at which it should have been charged by them. If the parties were not ad idem on this vital part of the contract of insurance, it would have an adverse effect on the contract itself. Since the period of policy is over, the appellant is under an obligation to refund the extra premium in terms of the policy. It cannot itself unilaterally make any adjustment from the amount of unutilised premium and retain a part of it on the ground that the premium charged was less than what it should have been charged.
