Where a warranty is broken, the assured cannot avail himself of the defence that the breach has been remedied, and the war ranty complied with, before loss.
The insurers, on their part, are bound, by the Act, to con tribute rateably to the loss in proportion to the amount for which they are liable under their contracts, and if any insurer pays more than his proportion of a loss, he is entitled to main tain an action for contribution against the other insurers. Where the assured has over-insured under an unvalued policy, a propor tionate part of the premium is returnable, but if the policies have been effected at different times, and the earlier policy has, at any time, borne the entire risk, or if a claim has been paid on the policy in respect of the full sum insured, no premium is return able in respect of that policy nor is any premium returnable when a double insurance is effected knowingly by the assured.
example of this is where there has been a total wreck, and the underwriter has paid a total loss, since he then becomes entitled to the proceeds of the sale of the wreck. On broad lines, the assured must account to the insurer for any diminution of the loss. A very general application of this right of subrogation is where the insurer pays a loss and then proceeds against a third party to recover; for his own benefit, but in the name of the assured ; in respect of a liability that third party may have in curred.
Re-Insurance.--Re-insurance is the indemnification of one insurer by another in respect of liabilities that the former has incurred in the course of business, and the Marine Insurance Act of 1906 gives the re-insured an insurable interest in his risks, but stipulates that unless the policy provides, the original assured has no right or interest in respect of such re-insurance. Re-in surance may be either facultative, which is the re-insurance of specified individual risks, or by treaty. A treaty of re-insurance is an agreement by one insurer to accept a stated proportion of the whole, or any specified part of, the business accepted by another, it being customary to place limits as to the maximum amount that may be given off under the treaty. In connection with these treaties an anomalous situation has arisen concerning their val idity under British law, for while they are undoubtedly contracts of marine insurance, the fact that they cover no specified amount makes it impossible to pay duty on them in accordance with the provisions of the Stamp Act so that it would seem that they are unenforceable in law. The leading legal decision on this point is that of the House of Lords In re National Benefit Assurance Co., Ltd. (31 Ll. L. Rep. 321). In practice, however, legal difficulties are not likely often to arise, since most treaties provide that stamped policies shall be issued in respect of the risks accepted under the contract, and in the event of dispute arising, legal action can be taken on these policies.
