Condition 3 on the other hand does not prohibit double insurance, or exempt the insurer from liability if double insurance exists, but requires the insured to disclose in writing any other insurance and requires particulars thereof to be stated in or indorsed on the policy by the insurer, and avoids liability unless those things are done. The effect of such a condition was considered in Steadfast Insurance Co. Ltd. v. F. & B. Trading Co. Pty. Ltd. [9] . In that case, during the term of a policy of fire insurance which contained a condition identical with condition 3, a cover note was issued by another insurer (Queensland Insurance) with respect to the same risk. The cover note was expressed to be "subject to the terms and conditions of this company's policy", and the policies issued by Queensland Insurance also contained a condition in the same terms as condition 3. No notice in writing was given to either insurer. The property was destroyed by fire and it was held that the insured had not lost the benefit of the first policy. The reasons for this conclusion were as follows. First, it was held, an insurance is "effected" within the meaning of a clause such as condition 3 only when what has been done attaches risk of loss to another insurer; in other words, if the contract with the other insurer contains a condition whose effect, in the circumstances, is that that insurer is at no time liable to indemnify the insured, the making of that contract is not the effecting of an insurance within the meaning of condition 3 [10] . Secondly, the effect of condition 3 was that because the claimants did not give Queensland Insurance notice of the earlier policy, Queensland Insurance was at no time under a liability to indemnify the claimants, so that the obtaining of the cover note did not constitute the effecting of an insurance covering the property issued under the earlier policy. Condition 3 was therefore no answer to the claim under the first policy [11] . It was submitted on behalf of the appellant that the fact that a cover note only was issued in that case distinguished it from the present case. The fact that a cover note was issued raised an additional question, viz., whether the cover note was subject to condition 3, or at least to that part of the condition which required written notice to be given, but once that question had been answered in the affirmative the fact that the second contract was in the form of a cover note was immaterial. The case is direct authority for the proposition that in the present case, unless the S.G.I.O. policy had been cancelled, the failure to give notice in writing of that insurance to C.M.L., and to state or indorse the particulars in or on the C.M.L. policy, entailed the consequence, subject to any question of waiver, that C.M.L. did not become liable under its policy - the condition on which its liability depended would not have been fulfilled in those circumstances. On this view, condition 10, providing for contribution, is to be reconciled with condition 3 by regarding the former condition as applying to other insurances of which notice has been given, and particulars of which have been stated in or indorsed on the policy. It further follows of course that condition 3 of the S.G.I.O. policy provided no answer to a claim on that policy, since no insurance had subsequently been effected.
