Marconi's Wireless Telegraph Co Ltd v Commonwealth (No 3)

In an action brought by Marconi's Wireless Telegraph Co Ltd against the Commonwealth for infringement of patent, the High Court had previously made an order for inspection of certain wireless telegraphic apparatus. The Commonwealth sought a stay of proceedings under this order pending an application for special leave to appeal to the Privy Council. The dispute centred on whether such a stay should be granted, given that refusal would render any potential appeal nugatory, while granting it without conditions might cause significant loss to the plaintiffs.

The legal issue before the High Court was whether it possessed the power and, if so, whether it should exercise its discretion to grant a stay of proceedings under its own order, pending an application for special leave to appeal to the Privy Council. This involved balancing the potential for an appeal to become nugatory against the risk of the plaintiffs losing the benefit of their action.

The Court reasoned that while it would not ordinarily grant such an application without very strong and special grounds, this case presented peculiar circumstances. It acknowledged that a refusal of the stay would render the Commonwealth's potential appeal nugatory, while a simple grant could cause the plaintiffs to lose the whole benefit of their action. Applying principles of preserving the rights of parties and balancing convenience, the Court decided to grant the stay. This was conditioned on the Commonwealth undertaking to expedite its application to the Privy Council and to pay such damages, whether legally claimable or not, as the High Court deemed just and fair compensation to the plaintiffs for any disadvantage suffered due to the stay. The Commonwealth was also ordered to pay the costs of the application.
