Subtitled: Law and, or, versus the Marketers: Evidence in the Cadburys v Darrell Lea case
I’ve been hearing rumours for some time now about evidence issues/problems/disasters in the recently concluded hearing in the case of Cadburys versus Darrell Lea, before Justice Heerey down here in the Vic Federal Court. So imagine my excitement when I realised there were no less than three decisions up on AustLII. They’re really interesting decisions because they say a lot about how law interacts with marketing people, marketing experts in these cases that are all about how consumers behave. Yes, I am a sad IP law geek. Never mind, I’ve come to terms with that. The decisions are:
- Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd [2006] FCA 363 (which I’ll call the Cadburys Expert Decision). In this decision, Justice Heerey ruled that a whole bunch of expert evidence from a marketing expert was inadmissible;
- Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd [2006] FCA 364 (I’ll call this one the Cadburys Survey Decision). In this decision, Justice Heerey ruled some survey-style evidence was admissible; and
- Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd [2006] FCA 386 (the Cadburys Hearsay decision). In this case, Heerey J ruled that some reports that included statements from consumers about how they reacted to purple weren’t admissible to prove the truth of those statements.
I was fascinated, partly because the Judge has chosen to exclude a whole lot of stuff (which must annoy the Cadburys lawyers), and partly because I’m currently teaching Trade Mark Law to undergraduate students. Of course, one thing you spend time talking about in such a course is matters of proof. Since I’ve had to dissect the reasoning for my students, I want to spend a little time in this post putting my thoughts out there. Comments welcome of course! (more…)
