  1. National Insurance Co. LTD vs Seema Malhotra

    Supreme Court of India 20 Feb 2001 Binding (SC)

    Court's Decision & Legal Precedent

    When an insured gives a cheque towards payment of insurance premium and the cheque is subsequently dishonoured by the bank due to insufficiency of funds, the insurer is not liable to the insured or their legal heirs to honour the insurance contract or pay claims arising from accidents that occurred before the cheque was dishonoured. This is because: (1) a cheque is a conditional promise to pay, not actual payment; (2) Section 64-VB of the Insurance Act requires that premium must be received before the insurer assumes any risk; (3) an insurance contract consists of reciprocal promises, and when the insured fails to pay the premium, the insurer is absolved from providing coverage; (4) the insurer's statutory liability to third parties under the Motor Vehicles Act is distinct from and does not extend to claims by the insured or their legal heirs.

    High Court 16 Jun 2023 Persuasive (High Court, Single Bench)

    Court's Decision & Legal Precedent

    Where an agreement of sale imposed reciprocal obligations to be performed by the stipulated date - the vendor to evict the ground floor tenants and the purchaser to evict the first floor tenant - and the purchaser led no evidence that he took any step to evict his tenant, he could not call on the vendor to perform; since neither side performed and time was of the essence, the discretionary relief of specific performance was rightly refused and the advance ordered refunded with interest.

    On this section: Applies Section 51 to a suit for specific performance: the promisor need not perform unless the promisee is ready and willing to perform his own reciprocal promise, and a plaintiff who defaults on his side of the bargain cannot enforce it.
