The appellants' final submission on s. 18 was that the combined effect of the provisions of the proposal and the policy was that any breach of the duty to disclose material facts constituted, in any event, a failure to observe or perform a term or condition of the contract. The basis of that submission was what was said to be the combined effect of the form of proposal completed by the appellants and the actual policy. The proposal, which contained answers to a number of specific questions relating to the risk, contained a declaration that "no matter has been withheld" and a provision that the appellants agreed that the proposal, including the declaration, "shall be the basis of the contract with the office whose policy [we] agree to accept". The policy, when it finally issued, recited that " the Insured has made to [the insurer] a written Proposal which it is hereby agreed shall be the basis of this contract and be considered as incorporated herein ". This submission is, however, confronted by difficulty at every step. As a matter of construction, it would seem that the statement in the proposal that "no matter has been withheld" should be read as referring to the answers to the specific questions which the form of proposal contained. None of those questions called for disclosure of Mr. Khoury's belief as to past thefts by a son from his business. Again, the reference to no matter being "withheld" is not appropriate to refer to a mere breach of the common law duty of disclosure in that the "word "withheld" means more than "omitted to communicate". It means "refrained from disclosing" and would not be satisfied by an omission through failure to advert to the subject": per Dixon J., with whom Rich J. agreed, Saunders [43] and see, to the same effect, per Starke J. [44] and Evatt J. [45] . There has been neither suggestion nor finding that the failure to disclose material facts in the present case was other than inadvertent. The real answer to the submission is, however, that the insurer in the present case relies upon breach of the common law duty of disclosure and it is not to the point that, if the non-disclosure also involved a breach of a term or condition of the contract, relief could be granted under s. 18 against the consequences of that breach. In that regard, as the decision in Saunders demonstrates, it is clear that the fact that the contract contained a provision in relation to withholding information would not, in the circumstances of the present case, warrant a conclusion that the ordinary common law duty to disclose material facts had been displaced. Indeed, as we followed the argument, it was not suggested that it would.
