A more limited case at trial than pleaded?
14 Darrell Lea submitted that the case run by Cadbury at trial was confined ultimately to the use of purple in the Christmas campaigns 2000-2004 and thus had ceased before the commencement of the proceeding in June 2005. This was said to be much narrower than the case pleaded. It will also be convenient to discuss in this context the vexed question of boysenberry.
15 In annexure A to the statement of claim there are eight samples of colour, each identified by a Pantone number, including Pantone 2658C. To a layperson's eye all samples appear as reasonably dark shades of purple; some are very dark, almost black. In particulars sub-joined to par 1 of the statement of claim "(t)he colour Cadbury purple" is said to be the colour perceived in the shades in annexure A "including those shades of 'purple' which are substantially similar thereto". In par 10 it is alleged that "by no later than 1995 Cadbury had achieved a substantial, exclusive and valuable reputation and goodwill throughout Australia in the colour Cadbury purple". This allegation is denied in par 11 of the defence.
16 Paragraph 21 of the statement of claim alleges that since approximately mid to late 2001 Darrell Lea has used in its business "a colour purple bearing a striking and obvious likeness to the colour Cadbury purple". This is denied in par 29 of the defence. But at an earlier stage of its defence Darrell Lea pleads (par 14 (a)) that since at least 1954 it has sold a variety of chocolate and confectionary products "packaged in purple coloured wrapping" and (par 14(b)) that since about early 1962 it has "adopted the use of a shade of purple known as 'boysenberry'" on signage and colour schemes in retail outlets, point of sale material, wrapping paper etc.
17 On the face of the pleadings, and notwithstanding par 29 of the defence, it might appear Darrell Lea is admitting that it has been using a purple that is not different from "Cadbury purple", or is substantially similar to "Cadbury purple". At the very least, it has not clearly distinguished the shade of purple it admits using from the alleged "Cadbury purple". Moreover, it is not clear whether Darrell Lea is saying that the "shade of purple known as 'boysenberry'" is or is not different from "Cadbury purple" or substantially similar to that colour.
18 In the letter of 27 February 2006 already referred to Darrell Lea's solicitors said in summarising its case:
"The shade of purple used by Darrell Lea is, in any event, not the same shade or shades used by Cadbury, and is of a decorative character rather than used as an indication of origin or association."
As Cadbury submits, this appears to amount to a denial that Darrell Lea used the shade claimed by Cadbury ("Cadbury purple") at all, even for Christmas 2000-2004. In the light of Darrell Lea's letter and par 29 of its defence it was reasonable for Cadbury to prepare for trial on the basis that it would have to prove Darrell Lea used "Cadbury purple", both at Christmas 2000-2004 and otherwise.
19 In opening Cadbury's case senior counsel said that Pantone 2658C was "the central core purple that Cadbury is concerned with" (T10). Senior counsel produced a box of Darrell Lea Soft & Hard Centres, subsequently tendered as exhibit V. The lid and a band around the top of the box were in a purple colour much the same as Pantone 2658C. The remainder of the box was in a lilac colour, noticeably lighter than any of the colours in annexure A. It is this colour which Darrell Lea referred to as boysenberry. Senior counsel for Cadbury said (T11):
"The matter's been confused by this reference to boysenberry. The nature of boysenberry, the precise shade of boysenberry that they [Darrell Lea] have identified in their material filed in the court is this lilac sort of colour, like the lower part of that [i.e. exhibit V], but in fact they are using colours that are identical with or very close to the Cadbury purple Pantone 2658C."
Later senior counsel said (T13) that an issue for determination would be what colour Darrell Lea had used. He agreed with what I expressed as my understanding of Cadbury's case, namely that Darrell Lea had used different shades of purple, some of which were "the same as the Cadbury Pantone purple". He also agreed with my understanding that Cadbury was not contending that "everything that could be described as purple can be protected by an order of the Court". In the course of the opening of senior counsel for Darrell Lea which immediately followed I confirmed my understanding in these terms (T25):
"In broad terms I understand the applicant's opening to be concerned with the colour Pantone 2658C or a colour similar to or very like that, I'm speaking roughly at the moment, but not all colours which could be described as purple, and not, looking at this box [exhibit V], boysenberry; it doesn't matter what you call it, but the colour of the bulk of the box is not sought to be injuncted."
20 Insofar as the trial dealt with the issue of the colours used by Darrell Lea, there was no narrowing of what was canvassed in the opening. Ultimately there were findings that Darrell Lea used a purple colour "much like that used by Cadbury", in particular at Christmas 2000-2004, but also at other times: [105]. Thus it is not correct to say, in effect, that any complaint as to Darrell Lea's usage of purple outside those times was abandoned by Cadbury. On the contrary, such usage was alleged, denied, or at least not admitted, by Darrell Lea, and proved by Cadbury.
21 Although there was some discovery, and evidence filed, about Darrell Lea's use of boysenberry, that is not surprising since such use had been positively pleaded by Darrell Lea and was thus a relevant fact. However, no time was taken up at the trial about boysenberry since Cadbury made clear from the outset that it was not seeking a restraint in respect of that shade.
