In conditions of political and constitutional uncertainty, administrat
ive law requires reassessment. Three analyses of the once neo-liberal
EU market (non-majoritarian, deliberative, heterarchical) show how its
evolving socialization has resulted in politically pluralist market a
dministration. Governmental, EU and private actors all voice their vie
ws within this administrative framework, but EC law does not determine
which single view is legitimate. EU administration should therefore b
e viewed as entailing a complex process of interest accommodation rath
er than the simple execution of legislative mandates. Constitutional p
rinciples to 'civilize' debate are needed, ensuring that EU market man
agement is not dominated by the strongest interest.
