In Telstra the applicant had pleaded that it entered into an agreement in reliance on misleading or deceptive conduct of one of the respondents, the State of New South Wales.
The agreement in issue was a large and complex commercial agreement between the State of New South Wales and the applicant, a subsidiary of a large foreign international telecommunications company.
The applicant had had, as one would expect, the assistance of its own lawyers before entering into the agreement.
The State claimed, at the pre-trial discovery stage, that privilege had been waived by the applicant on that advice because the advice went to the applicant's state of mind in connection with entry into the agreement and the pleading of reliance made state of mind in connection with the entry into the agreement an issue.
The advice was relevant to that issue.
Reliance was placed by the State in particular on Ampolex.
The majority (Branson and Lehane JJ) found waiver. Beaumont J dissented.
Where, as in this case, a party pleads that he or she undertook certain actions “in reliance on” a particular representation made by another, he or she opens up as an element of his or her cause of action, the issue of his or her state of mind at the time that he or she undertook such action.
The court will be required to determine the factor or factors which influenced the mind of the party so as to induce him or her to act in that way.
That is, the party puts in issue in the proceeding a matter which cannot fairly be assessed without examination of relevant legal advice, if any, received by that party.
In such circumstances, the party, by putting in contest the issue of his or her reliance, is to be taken as having consented to the use of relevant privileged material, or to put it another way, to have waived reliance on the privilege which such material would otherwise attract.
