August 13, 2026: The Swiss Federal Court has now published the decision in which it dismissed a technical challenge lodged by Australian billionaire Clive Palmers company Zeph Investments against the September 2025 ISDS tribunal award . The tribunal had declined jurisdiction over Zeph’s claims under the ASEAN-Australia-New Zealand free trade agreement (AANZFTA).
This decision confirms that Palmer is not a foreign investor and could not claim $300 billion over a disputed Western Australian iron ore mining license which he lost in the High Court. The decision confirms that he must pay the Australian government’s ISDS tribunal legal costs of $13.6 million. However, this is only the first of four claims Palmer has made against the government and three other claims totalling $120 billion are still on foot unless he withdraws them.
