We consider the process $e^+e^- -> \chi^+_i \chi^-_j$ at a linear collider with transverse beam polarization. We investigate the influence of the CP phases on azimuthal asymmetries in this process with subsequent chargino two-body decays. We show that triple product correlations involving the transverse beam polarization vanish if at least one subsequent chargino decay is not observed. We derive this result within the Minimal Supersymmetric Standard Model (MSSM) with complex parameters, however, it holds also in the general MSSM with SUSY flavour violation.
