Resumen: This chapter outlines the judicial history of the federal market of Australia¿the Commonwealth of Australia¿through the role of the High Court of Australia (High Court) in the constitutionalisation of free trade in that non-unitary market jurisdiction. It analyses the shift of Australia¿s constitutional court from an interpretive theory of free trade as a right to an interpretive theory of free trade as a principle. The chapter translates this historical exercise into a call against discrimination in market access on the argument that freedom of trade can, as a constitutional norm of non-discrimination, implement a scheme of political economy to integrate separate market jurisdictions for the greater equity of all market actors. The idea at the core of this argument is that of trade without barriers.
