"(i). One should identify the "transaction" in respect of which the disclosure has been made. (ii). That transaction may be identifiable simply from the nature of the disclosure made – for example, advice given by counsel on a single occasion. (iii). However, it may be apparent from that material, or from other available material, that the transaction is wider than that which is immediately apparent. If it does, then the whole of the wider transaction must be disclosed. (iv). When that has been done, further disclosure will be necessary if that is necessary in order to avoid unfairness or misunderstanding of what has been disclosed."
