  We propose T-odd and CP-odd odd asymmetries in order to analyze the impact of
CP violating phases in neutralino production and subsequent leptonic two-body
decays. We present numerical results of these asymmetries and of the cross
sections for complex parameters \mu, M_1 and A_\tau, which may be present in
the neutralino and stau sector of the Minimal Supersymmetric Standard Model if
CP is violated. The asymmetries arise on tree level and thus could be large
enough to be observed at a linear e+e- collider in the \sqrt{s}=500 GeV range
with high luminosity. We discuss the feasibility for measuring the asymmetries
by analyzing their statistical errors. Moreover we study the beam polarization
dependence of the asymmetries and of the cross sections and show that they both
can be enhanced considerably.
