                                    If the connection between the fundamental theory and neutrino mass
matrices M_
u is sufficiently complicated all traces of underlying
symmetries might be erased and an 'anarchical' M_
u, with random
entries, can arise. It has been claimed that such random matrices
generically prefer large mixing making unnecessary to invoke flavour
symmetries to explain the observed pattern of neutrino mixing angles. A
critical analysis of this idea (paying particular attention to the role
of unphysical phases and coordinate dependence) shows that
basis-independent, random M_nu's are not biased towards large values of
the neutrino mixing angles, contrary to previous claims. As a result,
the case for anarchy in the neutrino sector is considerably weakened.
