EMBATTLED federal MP Craig Thomson is confident that civil charges brought against him by Fair Work Australia will be dropped.
FWA announced on Monday it had launched the action in an attempt to recoup money the Member for Dobell allegedly misused while national secretary of the Health Services Union.
He could face fines of up to $450,000 and other substantial costs.
Mr Thomson stands accused of misusing hundreds of thousands of dollars on prostitutes and other expenses, allegations he strenuously denies.
"I look forward to having this particular set of actions thrown out, which we fully expect to happen," he told ABC radio on Tuesday.
Mr Thomson, who was suspended from the Labor Party at the height of the scandal in May, said in a statement on Monday he believed FWA had been "pressured" into laying the charges.
Attorney-General Nicola Roxon said in an interview on Monday night the Labor Party was unlikely to provide Mr Thomson with financial help to pay his mounting legal bills.
The NSW branch of the ALP had helped Mr Thomson with his legal expenses up until April.
Meanwhile, shadow attorney-general George Brandis entered the fray describing the case as "very grave".
"The fact that Fair Work Australia, after conducting such a thorough investigation, has now taken it to the next step - to progress this civil claim against him to recover the half a million dollars' worth of union members' money that he took - I think is a very grave matter," Senator Brandis said on Sky News.
"They wouldn't have taken this step unless they had been advised on an objective, clinical, forensic analysis of the evidence that they would succeed in that claim."
Prime Minister Julia Gillard would not be drawn on the matter when asked by reporters in India.
"I am not going to comment on a matter that is before the courts, and I am also not going to war-game a lot hypothetical questions about a matter that is before the courts," Ms Gillard said.
