Victoria’s Andrews government is facing a serious political challenge from the state’s militant construction union, which is preparing to sue Victoria Police for forcing union officials to leave a worksite.

The court action could wedge the Andrews government and force Premier Daniel Andrews to mediate between the CFMEU – a powerful financial and political player in the Labor movement – and the state’s police force, or to even pick a side.

Relations between the militant union and the Andrews government have become increasingly fractious over the past two months, and came to a head last Wednesday in a meeting between the Premier and some of his ministers and unions.

Those in the room included the CFMEU, the Electrical Trades Union and the Australian Manufacturing Workers' Union, which met to discuss the government’s Fair Jobs Code election promise.
