Embattled businessman Clive Palmer has lodged an appeal against last month's Supreme Court decision to strike-out parts of his defamation claim against

Prime Minister Malcolm Turnbull and Employment Minister Michaelia Cash after they allegedly blamed Mr Palmer for the collapse of Queensland Nickel at separate press conferences in Beijing in April 2016.

Mr Palmer claimed Mr Turnbull besmirched his name over the collapse and Senator Cash accused him of using funds from the company for his own benefit.

Mr Palmer's lawyer, Sam Iskander, wrote to Senator Cash's office in October last year, claiming the businessman was being shunned and excluded by friends, employees and professional colleagues as a result of her comments and feared reprisals against himself and his family.

Mr Palmer had previously launched a case seeking $10 million in compensation, but reduced it to $500,000 from the Prime Minister and Senator Cash in April, plus another $500,000 in interest.

The appeal against the June ruling, which was lodged in the Supreme Court on Tuesday, objected to the strike-out order and the delay between the ruling being lodged on June 5, and Mr Palmer receiving a copy on July 3.

Mr Palmer's legal team argued the decision meant he must "plead foreign law in circumstances where the Applicant should not be required to do so ... (and) invites further unnecessary pleading objections by the respondent".

They also believed Justice James Douglas's decision meant they would have to "further distil the imputation when the material complained of does not permit further distillation".

The date when the appeal would be heard in Brisbane had not yet been decided.

Queensland Nickel collapsed in early 2016 with debts of about $300 million, leaving close to 800 people out of work.
