I shall follow that approach.
92 As is usual in these cases, both sides called expert witnesses. Ultimately, however, the question is an "original decision for the court itself": Ancher, Mortlock, Murray and Woolley Pty Ltd v Hooker Homes Pty Ltd [1971] 2 NSWLR 278 at 286 per Street J. His Honour, after discussing the assistance that experts could give the judge in such cases, went on to say:
But the important point is that, in distinction from the judicial process in relation to expert evidence such as is normally encountered in litigation, a court in the present type of litigation is entitled, and, indeed, bound, to form and act on its own original opinion.
93 Senior counsel for Barrett pointed to the following close similarities between the al fresco quadrant feature that appear in both Barrett and Carlisle's plans and houses. (It is to be noted that in the Carlisle plans and houses these features appear in a mirror image to those of Barrett.)
(a) The sequence of rumpus, family, kitchen and meals areas around the central al fresco feature.
(b) The shape, relative space and configuration of these different surrounding areas.
(c) The right angled sides and corners of the al fresco area.
(d) The placement of the al fresco area between the meals and rumpus rooms.
(e) The grouping of these elements under a single side roof line.
94 Senior counsel accepted that there were some differences and in particular:
(a) while the position of the kitchen is the same in both, the configuration of the kitchen is different; and
(b) the Barrett al fresco is slightly more rectangular than that of Carlisle's which is more of a square shape.
95 Counsel for Carlisle relied on the proposition that the more simple, commonplace, familiar and straight forward the subject matter of a copyright work, the closer the similarity that will be required if infringement is to be found: Tamawood at [42]. He cited the well known case of Kenrick & Co v Lawrence & Co (1890) 25 QBD 99 at 103-104, a case which concerned the representation of a hand making the mark of a cross on a ballot paper.
96 This proposition, while undoubtedly correct, is of little assistance in the present case. Barrett's al fresco quadrant was truly original and commercially successful. Nor is it to the point, as counsel for Carlisle argued, that there are differences elsewhere between the Provence and the Barrett designs, such as in respect of the front facades. The fact that this is a "substantial part" case necessarily means that there are other parts of Carlisle's works in respect of which there is no allegation of copying.
97 Barrett's expert witness Dr John Cooke compared the Seattle plan to the Provence plan. He said:
The rear part of the [Provence] plan, containing Kitchen, Meals, Family, Alfresco, Rumpus, Bed 2, Bed 3, Bed 4, Laundry, Bath, WC, Laundry and Pantry is essentially very similar in layout (mirror reversed) to the corresponding area in the Seattle plan, with differences in the arrangement of wet areas and angled doors to Bed 3 and Bed 4 instead of the doors at right angles to the corridor in the Seattle plan.
The main difference in this part of the plans is the shape of the Kitchen and the access to the Laundry (direct from the Kitchen in the Respondent's Plan; from the bedroom corridor in the Seattle Plan). The position of the Laundry access in the Respondent's Plan has enabled the bedroom corridor to be shortened.
98 In comparing the respective houses, Dr Cooke said:
The vista from the Entry in the (Carlisle house) (Photograph No 67) is closed by a recessed and top lit wall feature, whereas the corresponding vista in the Seattle (Photograph No 4) is closed by an aperture in the wall beside the Rumpus room doorway and the doorway of the Rumpus room itself. The Rumpus room doorway is visible in this vista because the rear part of the plan of the (Carlisle house) is a mirror reversed version of the Seattle plan, with the result that the Entry access leads to the Rumpus room doorway in the Seattle whereas in the (Carlisle house) the Rumpus room is to the right of the Entry access.
However the spatial effects in both houses are similar.
99 He concluded:
Overall, in my opinion the arrangement of the Alfresco and surrounding living areas, including the indoor/outdoor connection and the Alfresco space itself is a highly significant feature of both houses [reference to photographs] as is the organization of the circulation areas to minimize waste and maximize virtual impact.
100 Dr Cooke made similar comments in relation to the Memphis plan compared with the Provence plan. He considered the Memphis plan a close version of the Seattle plan and subject to his general comments as to the latter.
101 In comparing the Memphis house to the Provence houseDr Cooke did not think that the numerous differences in colours, furnishings and floor materials affected the fundamentals. Again he thought the al fresco and surrounding living areas including the indoor/outdoor connection and the al fresco space itself was a "highly significant" feature of both houses.
102 In comparing the Aberdeen plan to the Provence plan Dr Cooke considered the Aberdeen plan a close version of the Memphis plan, mirror reversed. His comments on the comparisons between the Memphis plan and the Provence plan generally applied to the Aberdeen plan.
103 In conclusion, Dr Cooke noted that Barrett and Carlisle sell project homes in competition with each other and it was to be expected that houses of comparable size would contain very similar accommodation. It was not surprising in his view that competitors in the same housing market would produce roughly rectangular plans of single storey houses as such a plan is likely to fit a typical lot size more readily than other plan shapes. However, within those constraints he thought that Barrett and Carlisle had produced plans with "striking similarities", even though by no means identical. In particular, the al fresco area cut into the rectangular plan shape and bounded on three sides by informal living/dining areas was "a crucial factor in the generation of that substantial part of the plan and is a highly distinctive feature".
104 Carlisle's expert Mr Brickell noted a number of similarities and differences between the Provence plan and the Seattle plan. Some of these would seem to be irrelevant to the issues in this case, for example, the garage main entry and master bedroom suite (similarity) and the detailed layouts of the master bedroom suites (difference). His main grounds for his view that the Provence plan did not involve a reproduction of a substantial part of the Seattle were (i) that the design process followed a logical path over some four months whereas copying could have been achieved "in a matter if days by simply copying plans" and (ii) that competing project home builders with similar site constraints, market demands and cost objectives "may well arrive at design concepts resulting in plans that closely resemble those of their competitors".
105 Both these grounds seem to be more a matter of forensic comment than architectural analysis. Further, Mr Brickell was given no instructions on the design derivation of the three sketches which Carlisle purported to show the independent development of the Provence, and he sought no instructions on how these documents came into existence.
106 In cross-examination Mr Brickell was directed to the al fresco areas of the Seattle and Provence plans. He was asked:
Just having regard to these features if you don't mind. So you have got Provence in front of you, looking at the meals, kitchen, family, rumpus, alfresco?---Yes.
And you know it has got a single covered roof across those features?---Okay
And if you compare that to the Seattle would you agree the features in both houses save in respect to the, you can see a difference in the way in which the kitchen benches are depicted, save in that respect do you agree the plans are very similar?---I said that in my report.
Yes, and so much so that they are almost identical?---Well, I said they are similar.
And would you adopt a description extent of similarity, very similar?---I would say they are similar. I am not prepared to say they are identical. I think there are some aspects in there which may appear to be insignificant about the location of the kitchen, the relationship of the room that is behind the kitchen area which do impact on the similarity.
Well, otherwise in an overall sense those features are similar in both houses?
---Yes.
107 Although Mr Brickell commented on the commonality of the al fresco design feature, he made no enquiry concerning the state of design in relation to the actual use of the feature before January 2000. In maintaining the commonplace nature of the al fresco he relied on examples which were post-Seattle.
108 Mr Quigley was asked to undertake a design task based on reference to the Rochester 30. Whilst he is a distinguished architect I am not persuaded that his evidence was of any assistance in this case. As already discussed, the fact that the Rochester might have been developed by a rumpus room and roof line over the courtyard is not to the point. Whether it was "logical" or not, the fact is by 1999, nobody other than Barrett had done it.
109 In conclusion I find that there was sufficient similarity between the al fresco quadrant part of the respective plans and houses. I think this conclusion could be reached without the finding of deliberate copying, but such a finding adds weight to the evidence supporting this conclusion.
