Craig Thomson case back in court

The Fair Work Commission is seeking to settle the last of its legal action against disgraced former MP Craig Thomson.

Mediation between the commission and Thomson's lawyers will begin in the Federal Court in Melbourne on Thursday.

Federal Court action against the former Labor member for Dobell and HSU official started in October 2012 after a three-year investigation by the commission.

The initial action alleged Thomson, the HSU's national secretary between 2002 and 2007, committed 37 breaches of industrial law and another 25 of HSU rules.

The commission has been seeking compensation for the union's alleged losses and civil penalties.

The remaining unsettled matters are understood to relate to Thomson's alleged use of union money to fund election campaigning in the NSW federal seat of Dobell.

In separate court action, Thomson was found guilty in February this year of 65 dishonesty charges and in March he was sentenced to one year in jail, with nine months suspended.

His appeal of the conviction and sentence is due to go before court in November.

The parliament's privileges committee is also investigating whether Thomson, in a statement in May 2012, deliberately misled the House of Representatives.
