The Queensland Court of Appeal has dismissed a union challenge to the state government's industrial relations legislation. The court found the laws do not breach the constitution.
The ABC reports amendments to the Public Service and Industrial Relations Acts by the state government, remove job security clauses in agreements for public sector employees.
The Australian Workers Union and the Together Union argued the changes were unconstitutional.
But the court ruled the laws did not impinge in any way on the decision making or impartiality of the state's Industrial Relations Commission.
The ABC reports the Together Union has vowed to continue legal action against the State Government.
The union said it has spent about $200,000 on legal fees for this case and others against the state government.
Secretary Alex Scott said further challenges to state laws are due to go to court next year.
