  The generalized version of the chiral Schwinger which contains both the
vector and axial-vector interaction with unequal weight is exactly solvable. It
contains a massive and a massless boson in its theoretical Spectra. However,
after imposition of a chiral constrain it loses exactly solvability. So the
theoretical spectrum can not be determined precisely and consequently, the mass
generation and confinement aspect of fermion becomes unsettled which is in
sharp disagreement with the recent publication [18].
