  The recent results from Belle of the $\tau^-\to\nu_\tau\pi^-e^+e^-$ analysis
has incentivated us to make a reanalysis of a former work where the Structure
Dependent parts are obtained using Resonance Chiral Theory. Here we rely on the
same theory accounting for effects that explicitly break such symmetry. A
motivation is the involved $W\pi\gamma^\star$ vertex, utterly relevant in
computing $\tau^- \to \nu_{\tau}\pi^-$ radiative corrections.
