Query: Can The Majorana neutrino CP-violating phases be restricted ?   We reanalyze the constraints in neutrino masses and MNS lepton mixing
parameters using the new data from the terrestrial (KamLAND) and astrophysical
(WMAP) observations together with the HEIDELBERG-MOSCOW double beta decay
experiment. It leads us to the almost degenerate or inverse hierarchy neutrino
mass scenario. We discuss the possibility of getting the bound for the Majorana
CP violating phase.
