44 In Telstra v BT Australasia (1998) 85 FCR 152 Branson and Lehane JJ, Beaumont J dissenting, held that consent in s 122(1) should be construed to extend to imputed consent. At 168 the majority stated:
In our view, s 122(1) of the Act is to be construed as reaching to cases in which the client or party concerned is deemed to have consented to the disclosure of the otherwise privileged material in the sense discussed above. To constrain the operation of the subsection to instances of voluntary assent to the adducing of evidence which would otherwise attract client legal privilege is, in our view, to give insufficient weight to the context in which the subsection is found, and to the common law background against which the Act as a whole is to be understood. The primary judge expressed the view that, while "consent" in s 122(1) might include implied as well as express consent, it would be straining language excessively to hold that it extended to a "consent" imputed to a party on the basis of fairness. Presumably an implied consent, as envisaged by his Honour, is one that is found to be, on the evidence, real and voluntary though not express. In fact, however, the cases, not surprisingly, use the terms "implied" and "imputed" interchangeably (see, for example, Maurice at 488 per Mason and Brennan JJ, Goldberg at 95-96 per Deane, Dawson and Gaudron JJ and at 109 per Toohey J). Once it is accepted that consent for the purposes of the section extends beyond express consent, we think it should be taken to extend to imputed consent. In particular, if that were not so, a defendant ordinarily would no longer be able, where the plaintiff alleges that a transaction was procured by the defendant's undue influence, to lead evidence to the effect that the plaintiff had comprehensive legal advice, immediately before entering into the transaction as to its effect. We cannot believe that that was intended. It follows that, in such cases, the position has changed little, if at all, following the introduction of the Act. Of course, as the Adelaide Steamship case demonstrates, the position may be different where the conduct relied upon is some disclosure of legal advice, but that need not be further considered here.
