AN arbitrated Western Australian decision in Clive Palmer's favour and which may have severe financial ramifications for the Liberal Western Australian Government may be at the heart of a concentrated attack on Fairfax MP Clive Palmer by Queensland's Premier and Deputy Premier and WA Premier Colin Barnett.

The decision was confidential to the party's involved - Mr Palmer's Mineralogy, the Chinese-owned International Minerals and the WA Government - until it was tabled in Queensland Parliament at 1am last Friday by Palmer United Party Queensland leader Dr Alex Douglas.

The document can be accessed on the Queensland Parliament website but Hansard's recording of the matter won't be included in the record of proceedings until today.

The decision found that Mr Barnett, the WA Mines Minister, failed to deal with in accordance with legislation a Mineralogy application for a project to mine and export ore from its Susan Palmer deposit named after Mr Palmer's late first wife.

The arbitrator Michael McHugh's judgment noted that Mineralogy had foreshadowed a potential claim for damages based on Mr Barnett's breach in failing to deal with the August, 2012, submission.

However he said no evidence had been tendered in support of such a claim and it was not appropriate for him to make an order in respect of it.

The damages claim, which could be as high as $1 billion, is now likely to be pursued in another court with Mr Palmer saying delays had cost mum and dad investors hundreds of millions of dollars.
