“I trust this decision will finally close the book on this long-running saga,” he said.
Palmer claimed the legislation was “akin to the actions of a banana republic” in a notice of arbitration to the international tribunal after the High Court rejected the challenge.
The arbitration court operated under a “very unusual system” that allowed foreign investors to sue the state they invested in, outside of that state’s courts, international-state dispute settlement expert Jonathan Bonnitcha said.
“It’s a way to basically internationalise a dispute,” the UNSW law associate professor said.
The ad-hoc tribunals are comprised of two arbitrators nominated by the claimant and respondent, who then agree on a third.
The government has a policy to exclude the process from future trade agreements, in line with some others internationally.
Palmer’s other cases might also end if subsequent tribunals adopt the most recent position but precedents are not binding under the system.
In addition to being one of Australia’s wealthiest citizens, Palmer is also a prominent figure in politics who has chaired multiple parties and represented the Queensland seat of Fairfax in federal parliament.
His foreign investor claim jarred with much of his often nationalistic political messaging.
“Those ads don’t generally say a lot about suing the Australian government for hundreds of billions of dollars,” Bonnitcha said.

His campaign ahead of the 2025 election under the Trumpet of Patriots banner included a call for Australians to “wake up”.
None of the party’s candidates were elected.
The tribunal’s decision, yet to be made public, ordered Palmer to pay costs of $13.6 million, Ms Rowland said.
Palmer will review the judgment, a spokesman said.
The dispute was subject to a three-day hearing in The Hague on jurisdiction and admissibility in September 2024.
Australian Fair Trade and Investment Network convenor Patricia Ranald said Palmer’s claim had exposed “the absurdity” of international-state dispute settlement.
“Which lacks proper legal safeguards and allows investors to game the system and make outrageous claims,” she added.
“This is a narrow escape and there could be more claims from other fossil fuel or other foreign investors.”
