  We analyze the effects of CP-violating phases on the electric dipole moment
(EDM) of electron and neutron in the constrained minimal supersymmetric model.
We find that the phases phi_{\mu} and phi_{A_0} have to be strongly correlated,
in particular for small values of the SUSY mass parameters. We calculate the
neutron EDM in two different models, the Quark-Parton Model and the Chiral
Quark Model. It turns out that the predictions are quite sensitive to the model
used. We show parameter regions in the M_0-M_1/2 plane which are excluded by
considering simultaneously the experimental bounds of both electron and neutron
EDM, assuming specific values for the phases phi_{\mu} and phi_{A_0}.
