  Neutrino physics is nowadays receiving more and more attention as a possible
source of information for the long--standing investigation of new physics
beyond the Standard Model. This is also supported by the recent change of
perspectives in neutrino researches since the discovery period is almost over
and we are entering the phase of precise measurements. Despite the limited
statistics collected for some variables, the three--flavour neutrino framework
seems well strengthening. However some relevant pieces of this framework are
still missing. The amount of a possible CP violation phase and the mass
ordering are among the most challenging and probably those that will be known
in the near future. In this paper we will discuss these two correlated issues
and a very recent new statistical method introduced to get reliable results on
the mass ordering.
