We examine the possible resolution of the recently observed polarization anomaly in B{sup 0}(B{sup 0}){yields}{phi}K*{sup 0}(K*{sup 0})-decay within R-parity violating (Re{sub p}) SUSY. We show that a combination of the superpotential trilinear Re{sub p}-interactions, with the couplings {lambda}{sup '}, and the soft SUSY breaking bilinear Re{sub p} sneutrino-Higgs mixing, proportional to {mu}-tilde{sup 2}, can potentially generate the effective operators with the chirality structure necessary to account for this anomaly. However, we demonstrate that the existing experimental data on B{sub s}{yields}{mu}{sup +}{mu}{sup -}-decay lead to stringent upper limits on the Wilson coefficients of these operators, which are about 2 orders of magnitude below the values required for the resolution of the B-decay polarization anomaly, and, therefore, it can hardly be explained within the Re{sub p} SUSY framework. As a byproduct result of our analysis we derive new limits on the products of the soft bilinear and the superpotential trilinear Re{sub p}-parameters of the form {mu}-tilde{sup 2}{lambda}{sup '}.
