Roadshow Films Pty Ltd v iiNet Ltd

The High Court of Australia considered applications for leave to intervene and to be heard as amicus curiae in proceedings between Roadshow Films Pty Ltd and iiNet Ltd. The dispute concerned allegations of copyright infringement by iiNet's customers. Several third parties sought to participate in the proceedings, either as interveners or as friends of the court.

The central legal issue before the High Court was the criteria for granting leave to third parties to intervene or to be heard as amicus curiae in appellate proceedings. Specifically, the Court had to determine whether the applicants had demonstrated that their intervention or submissions would significantly assist the Court and that their interests were directly affected by the outcome of the appeal.

The Court applied principles governing the joinder of parties and the admission of amici curiae, emphasising that such applications are exceptional. It considered the potential for duplication of arguments already presented by the parties and the extent to which the proposed submissions would genuinely assist the Court in its determination of the legal issues. The Court distinguished between the roles of interveners and amici curiae, noting that intervention typically requires a more direct and substantial interest in the subject matter of the litigation.

Consequently, the Court dismissed the applications for intervention by the Australian Recording Industry Association Limited and the Australian Digital Alliance Ltd. It also dismissed the applications for leave to be heard as amicus curiae by the Media, Entertainment and Arts Alliance, the Screen Actors Guild, and the Australian Privacy Foundation. However, limited leave was granted to the Australasian Performing Right Association Limited and Communications Alliance Limited to be heard as amicus curiae, subject to the condition that their submissions did not duplicate those of the parties.
