Thus, only in its elaboration by neoliberal constitutionalists in the 1960s did the EEC offer a realization of the double government dreamed of by Hayek since the 1930s. Mestmäcker, in par­tic­u­lar, offered a crucial bridge between the ideas of the first generation of Geneva School neoliberals and thoroughgoing theories of multilevel governance—­a link more often asserted than proven by scholars. What is crucial is that Mestmäcker went further. In the Treaty of Rome as self-­executing constitution and the Eu­ro­pean Court of Justice as guardian, he pioneered a model of supranational governance that had not only liberal princi­ples at its core but a mechanism of enforcement capable of evading contamination by demo­cratic claims-­making.
