We investigate the muon anomalous magnetic dipole moment (MDM), the muon electric dipole moment (EDM) and the lepton-flavor-violating decays of the \ensuremathτ lepton, \stackrel\ensuremath→\ensuremathτ\ensuremathμ\ensuremathγ and \stackrel\ensuremath→\ensuremathτ3\ensuremathμ, in the CP-violating minimal supersymmetric standard model with nonuniversal soft-supersymmetry breaking. We evaluate numerically the muon EDM and the branching ratios B(\stackrel\ensuremath→\ensuremathτ\ensuremathμ\ensuremathγ) and B(\stackrel\ensuremath→\ensuremathτ3\ensuremathμ), after taking into account the experimental constraints from the electron EDM and muon MDM. Upon imposition of the experimental limits on our theoretical predictions for the aforementioned branching ratios and the muon MDM, we obtain an upper bound of about 10^\ensuremath-23ecm on the muon EDM which lies well within the explorable reach of the proposed experiment at BNL.
