Nowadays in France developments in the system for regulating the econ omy are causing a recomposition of institutions and a transformation of professional role models. A good example of these trends is provided by changes in the judiciary. The latter, which previously remained on the periphery of the business world, is playing an increasingly central role in a new system. As a result, it has been obliged to redefine the principles on which it has traditionally based its autonomy and legitimacy. The judge's position (and that of all legal experts operating in a segment of economic regulation whose structure has not yet been established) depends on the success of what the President of the Supreme Court has called a 'cultural revolution' (Drai 1 988). 1 What is at stake is even greater, since we are witnessing the birth of a new means of regulating society, in which jurists practising private law will have to improve their professional situation.
