The substantive constraints of privatization initially deal with the question of
whether a certain privatization is constitutionally permitted in the first place, or not,
because many countries like France, protect the public services by the provis
ions of
the constitution, and It is a common feature of constitutional texts that they include
provisions defining the main branches of government - the executive, the legislature
and the judiciary - and these provisions may be interpreted, that it would not be
possible to completely privatize this functions.
