A natural theoretical framework is presented which allows for small departures from quark-lepton universality such that different G_F and sin^2(theta_W) values are applicable for different processes. In particular, the inequality (G_F)^{NC}_{lq} < (G_F)^{CC}_{lq} < (G_F)^{CC}_{ll} < (G_F)^{NC}_{ll} holds. New physics is predicted at the TeV scale.
