The next question is whether the appellants, as the insured, had an insurable interest. They were equitable mortgagees of the insured premises under their liens and the deposit of securities. Bunyon on Fire Insurance, 5th ed., at p. 42, summarizes insurable interests as "any legal or equitable estate, or right which may be prejudicially affected, or any responsibility which may be brought into operation by a fire." Of the case of a mortgagee, Bowen L.J., says in Castellain v. Preston[11]: - "If he has the legal ownership, he is entitled to insure for the whole value, but even supposing he is not entitled to the legal ownership he is entitled to insure primâ facie for all. If he intends to cover only his mortgage and is only insuring his own interest, he can only in the event of a loss hold the amount to which he has been damnified. If he has intended to cover other persons besides himself, he can hold the surplus for those whom he has intended to cover. But one thing he cannot do, that is, having intended only to cover himself and being a person whose interest is only limited; he cannot hold anything beyond the amount of the loss caused to his own particular interest." And his Lordship points out that the whole matter is regulated by the doctrine of indemnity. As the Chief Justice has pointed out, the debtors owed the appellants more than the amount of the policy at the time of the loss, so that there can be no problem to solve as to the extent of the mortgagees' insurable interest. They can recover at any rate to the amount of the debt due to them when the fire took place, upon proof and within the value insured. A further defence was raised under condition 6 of the policy, which, if there is a new contract such as I have endeavoured to show, is a condition of that contract. It will be observed that it is almost totidem verbis with the condition which was the subject of the decision in Weir v. Northern Counties of England Insurance Co.[12]. The only difference on which counsel placed serious reliance was that in the present case the words "unless and" are inserted, and precede "until" in the last sentence of the condition. Notice, with a statement and account under this condition, was not sent to the insurers until 17th December, a year after the fire, and as we are told, after the buildings had been reinstated. It was argued that the delivery of the statement, and within fifteen days after the happening of the loss, was a condition precedent to the right to recover. I think Weir's Case[13], so far as it goes, ought to be followed by us. It is now more than 28 years old, and so far as I can learn, has not been challenged during that time, although there must have been many opportunities of raising the question in British Courts. The decision has, no doubt, been followed in the transaction of insurance business throughout the interval, and we should do nothing to disturb it now. Moreover I am strongly disposed to think it correct. For very many years the clause existed without the addition of the words beginning "and in default thereof," and in that state it was repeatedly construed as imposing a condition precedent on the right to recover. No doubt its very plain terms justified that interpretation, which it received in the several instances cited in Weir's Case[14]. The distinct inference from the words was that if the fifteen days had elapsed without delivery of the notice, account, &c., on the part of the insured, he could not afterwards be allowed to sustain his claim. But expressum facit cessare tacitum, and in Weir's Case[15], it was held that the added words "have the effect of only deferring the right to payment until the notice and account are given, and thus enlarging the time." The Court thought that the words had been added with the purpose of defining what should be the consequence of failure to comply with the requirements within the time limited. Instead of saying (as tacitly it had said) that in default no action shall be brought or payment made, it says that no claim shall be payable until such notice and account &c. are given. "Besides," added the Court[16], "the words are those of the company's own form, and the maxim applies, fortius contra preferentem." It was held, therefore, that the delivery of the notice, account, &c., within fifteen days was not a condition precedent.
