The parties' submissions
7 Flameglow and Hotpoint each submit that, as they took no active part in the appeals, there should be no order for costs against them.
8 Garth Living, Cohen Nominees and Bunnings have made no submissions on the question of costs or on any other matter arising from the Full Court's decision in the appeals.
9 Bitech submits that, in respect of the appeals, costs orders should be made in its favour on a party-party basis against all respondents, and, in respect of the cross-appeal, against Garth Living, Cohen Nominees and Bunnings.
10 Bitech accepts that only Garth Living took an active role in the appeals but submits that, by filing written submissions, Cohen Nominees and Bunnings were supporting Garth Living's position and, in seeking to benefit from any outcome in Garth Living's favour, they should, as unsuccessful parties in the appeals concerning them, be liable for costs. Bitech submits that Hotpoint and Flameglow should be liable for costs because they did not consent to the appeals concerning them.
11 As to the costs of the cross-appeal, Bitech submits that costs should be ordered against Garth Living as the unsuccessful cross-appellant. It also submits that, because Cohen Nominees and Bunnings sought to benefit from any declaration of invalidity that might ensue as a consequence of Garth Living's cross-appeal, they too should be liable for costs equally with Garth Living.
12 Bitech also seeks variations of the costs orders made by the primary Judge. It seeks cost orders in its favour with respect to the proceedings at first instance against Garth Living, Cohen Nominees, Bunnings and Hotpoint on the basis that, having regard to the Full Court's reasons, Bitech should have succeeded in each proceeding. It submits that it should have the benefit of orders that those respondents be liable jointly and severally for those costs, rather than for an identified portion of them. In support of this outcome Bitech submits that, although it commenced separate proceedings against different respondents, the issues in the proceedings were broadly the same; the conduct of the respondents in those proceedings was broadly the same; the proceedings were heard together, with evidence in each proceeding being evidence in all other proceedings; and the heater designs were all materially identical, the heaters being imported from the same manufacturer. No respondent has made a submission against the variation that Bitech seeks.
