In his book The State in Capitalist Society, Ralph Miliband registers those different elements, which together constitute the state. The first, but by no means the only element of the state apparatus, is the government. The second is the administrative element, the civil service or the bureaucracy. This administrative executive is, in liberal-democratic systems, supposed to be neutral, carrying out the orders of politicians who are in power. In fact, however, the bureaucracy may well have its own authority and dispose of its own power. Third, in Miliband’s list come the military and the police, the ‘order-maintaining’ or the repressive arm of the state; fourth the judiciary. In any constitutional system, the judiciary is supposed to be independent of the holders of government power; it can act as a check on them. Fifth, come the units of sub-central or local government. In some federal systems, these units have considerable independence from the central government, controlling their own sphere of power, where the government is constitutionally debarred from interfering.
