  Charged Higgs production in association with staus in electron positron
annihilation is a signal of supersymmetry with bilinear R-Parity violation. In
this model, neutrino masses and mixing angles are generated due to mixing with
neutralinos. We show how parameters related to neutrino physics can be
determined at a $500 {\mathrm fb}^{-1}$ Linear Collider from measurements of
charged Higgs and stau production cross sections and decay rates. This can be
achieved in AMSB where charged Higgs and stau can have similar masses.
