We analyze the effects of CP violating phases in a fully left-right extension of the minimal supersymmetric model. These phases appear from both the heavy and light neutrino sectors: two CKM-type phases, and four Majorana phases. We study observable effects of these phases in lepton flavor violating decays, such as the T-odd asymmetry in $\mu^+
\rightarrow e^+e^+e^-$ , as well as in the leptonic electric dipole moments. We impose the experimental constraints from the mixing of light neutrinos and analyze cases in which the heavy and light neutrinos are either degenerate, or hierarchical, and highlight the dominant variables in each case. CP violating phases in both the heavy and light neutrino sectors of the left-right supersymmetric model have unique features which, if tested in the charged lepton sector, may distinguish the model from other supersymmetric scenarios.
