Supersymmetric (SUSY) theories include many new parameters, some of which are CP-violating. Assuming that SUSY is found at a future high-energy collider, we examine the decay t-tilde{sub 2}{yields}t-tilde{sub 1}{tau}{sup -}{tau}{sup +} with an eye to obtaining information about the new CP phases. We show that there are two CP-violating asymmetries which can be large in some regions of the SUSY parameter space. These involve measuring one or both of the {tau} spins. These asymmetries are particularly sensitive to {phi}{sub A{sub t}}, the phase of the trilinear coupling A{sub t}.
