The Government of Victoria is the executive administrative authority of the Australian state of Victoria. Functioning within the scope of Victoria's status as a sub-national parliamentary constitutional monarchy, the Government was first formed in 1851, when Victoria first gained the right to responsible government. Since the Federation of Australia in 1901, Victoria has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth. Under the Australian Constitution, Victoria ceded legislative and judicial supremacy to the Commonwealth, but retained powers in all matters not in conflict with the Commonwealth. The Victorian Government enforces Acts passed by the state Parliament through its vast array of government departments, statutory authorities and other related agencies. The Government is formally presided by the Governor of Victoria, who exercises their executive authority granted by the Constitution through the Executive Council, a body consisting of senior cabinet ministers. In reality, both the Governor and the Council are mostly ceremonial, with the Premier and their ministers having the real power over policy decisions, appointments and other executive orders made by the Governor-in-Council.
