Palmer eyes mediation in defamation case

·1-min read

Billionaire Clive Palmer has flagged he's willing to participate in mediation in his defamation claim against West Australian Premier Mark McGowan.

But the battle is likely to stretch into next year after Mr McGowan indicated he presently "does not wish to participate" in the negotiation process.

Mr Palmer last year filed a lawsuit against the premier, claiming his public comments, including labelling him the "enemy of West Australia", had damaged his reputation.

Mr McGowan lodged his own defamation counter-claim a month later.

Federal Court Justice Richard White this week noted the contrasting positions of the two parties on mediation in a case management hearing.

He said it was "improbable" the matter would go to trial until the first quarter of 2022.

A separate High Court matter between Mr Palmer and the state of Western Australia is scheduled to be heard on June 15.

It relates to extraordinary legislation passed in WA's parliament in August to amend a 2002 state agreement with Mr Palmer's Mineralogy company and terminate arbitration between the two parties.

The bill is designed to block Mr Palmer from claiming damages from the state.

Mr Palmer is seeking almost $30 billion from WA taxpayers over a decision by the former state government not to assess one of his mining projects.

The federal government on Friday filed a notice of intervention rejecting Mr Palmer's position.

"The Commonwealth intervenes to contend that the provisions ... do not infringe any constitutional limitation identified by the plaintiffs," the notice said.

NSW and the Northern Territory have also intervened in support of WA.
