We use the available information on the solar and atmospheric mixing parameters |V_e2| and |V_mu3| provided by neutrino oscillation data. We conclude that large values of |V_e3| are preferred at 95% confidence level. This, in turn, favours large values for J_lepton compared to CP violation in the quark sector.10 pages, 6 figuresHigh Energy Physics - Phenomenologytext
