Under-siege federal MP Craig Thomson expects civil charges brought against him by Fair Work Australia (FWA) will be thrown out.
The suspended Labor man turned independent faces fines of up to $450,000 and compensation payments after the workplace watchdog filed civil charges in the Federal Court on Monday.
The charges broaden existing claims Mr Thomson spent hundreds of thousands of dollars of union funds on prostitutes and other personal expenses while national secretary of the Health Services Union.
Mr Thomson is maintaining his innocence.
'Absolutely,' he told ABC radio on Tuesday.
'I look forward to having this particular set of actions thrown out, which we fully expect to happen.'
Mr Thomson believes FWA has been pressured into filing the civil claims, and is trying to save face after taking years to investigate his union activities.
