The defendants (Amcor) sought to use the letter of advice in cross examination and objection was made to that use by the plaintiff under s118 of the Evidence Act 2008 (Vic) (the Evidence Act) and s138 of the Evidence Act. Amcor said that it could use the letter by reason of the plaintiff acting inconsistently with the maintenance of a claim of privilege by the following conduct:
- The letter of advice was received by two third parties.
- The letter of advice was listed in a supplementary affidavit of documents and the plaintiff did not object to it being listed in that document.
- The letter of advice was referred to in the opening address of Amcor's senior counsel and the plaintiff did not object to it being referred to.
