"59. Present Law - An insured is required to disclose to the insurer all material facts relating to the insurance he proposes to effect and which are material to the insurer's assessment of the risk he is incurring or as to the premium he should charge. At common law, some lines of authority support the proposition that the insured's obligation is to disclose every material fact known to him and which a reasonable man would realise to be material. Other authorities, and particularly more recent Australian cases have rejected this approach in favour of the 'prudent insurer' test ie a fact is material if it would have reasonably affected the mind of a prudent insurer in determining whether it will accept the insurance, and if so, at what premium and on what conditions.

> 60. The duty exists before the contract is entered into and continues until the contract is concluded. If an insured fails to do so, the insurer may, on discovering the full facts, elect to avoid the contract of insurance ab initio and he may do so whether or not any loss has occurred. An insured need not disclose facts

> (1) which are known, or presumed to be known, to the insurer;
>
> (2) which are of common knowledge;

> (3) which tend to diminish the risk;

> 61. Proposed Law - An insured will have, before the contract is entered into, a duty to disclose to the insurer all material facts of which he is aware. His duty will be to disclose those facts which he knows or which a reasonable person in the circumstances could be expected to know would be relevant to the insurer in his decision to accept the risk and, if so, on what terms (clause 21(1)). The insured is not required to disclose matter
>
> (1) that diminishes the risk;
>
> (2) of common knowledge;
>
> (3) that the insurer knows or in the ordinary course of his business as an insurer ought to know; or
>
> (4) as to which compliance with the duty of disclosure is waived by the insurer. An insurer will be deemed to have waived compliance if, in response to a question in a proposal form, the insured failed to answer the question or gave an obviously incomplete or irrelevant answer to it.

> 62. Rationale - Clause 21 clarifies the existing law by specifying the test of materiality. It also ameliorates the existing law, particularly in so far as the 'prudent insurer' test has been applied, for this test takes no account of the insured's circumstances or the circumstances in which the contract of insurance is negotiated. Clause 21 mitigates the application of the duty by providing that the insured's duty is only to disclose those facts which he knew or a reasonable person in the circumstances would have known to be relevant to the insurer's assessment of the risk. As an examination of what a reasonable man would know cannot take place in a vacuum, a court would not be precluded from considering an insured's position and circumstances in applying the test. Clause 21 also clarifies the circumstances in which an insurer will be deemed to have waived compliance with the duty." (emphasis added)
