Based on experimental data by Bell Collaboration, we present a phenomenological analysis of the angular distributions in tau- -->K_S pi-nu_tau decay. Our study shows that the angular analysis could lead to some interesting observables, and the future experimental investigation of these obseverables might be very helpful to reveal the nature of the scalar components of the decay. New physics contributions from two-Higgs-doublet model to this decay have also been examined.
