The appellants seek to set aside this interim injunction granted by the Australian Industrial Court. The respondent had sought a more qualified injunction. In this Court the respondent did not support the Australian Industrial Court's order, but still sought a more limited order. Much argument was addressed to the question whether the respondent could succeed on the final determination of the application for injunction. In my view (irrespective of any proprietary rights in the respondent), if the appellant's conduct in using the words "Hornsby Building Information Centre", is capable in the circumstances of misleading or deceiving persons into regarding its Centre as associated with the Sydney Building Information Centre, then the Court may under s. 80 (1) enjoin the appellants from the conduct unless precautions are taken to overcome the misleading or deceptive nature of the conduct (for example, by identifying the Centre as the first appellant's own). The requirement that such precautions be taken should be reviewable, in order to meet the practical necessities. The case raises considerations resembling those in Sears, Roebuck & Co. v. Stiffel Co. [11] and Compco Corp. v. Day-Brite Lighting Inc. [12] (in which the national-state legislative roles were opposite to those here). There was much evidence to the effect that the Sydney Building Information Centre was conducting a service primarily of "presenting and disseminating information on past building techniques, modern trends and progress in the building industry, particularly with reference to building materials, building practice and building industry products and their correct use, to professional trade and private users of information, materials and products". It had become accredited with the international Permanent Conference of Building Centres and had received much official recognition for its educational activities and services to the building industry and the public.
