Melbourne Corporation v Commonwealth
Melbourne Corporation v Commonwealth, also known as the Melbourne Corporation case or the State banking case,[1] is an important case in Australian constitutional law.

SignificanceThis constitutional protection is one of the few reliable protections in the Australian Constitution against legislative and executive power, the other main protection being the Chapter III Separation of Powers Doctrine. Recent developmentsThe recent case of Austin v Commonwealth[3] conflated the original two-limbed test of the original case into an expanded 1st limb so that a commonwealth law that affects a state's ability to administer itself is constitutionally invalid.
