Nodland Ralston (PRL,1997) investigated the cosmological anisotropy of electromagnetic fields.In this paper we show that it is possible obtain a torsion correction to Nodland-Ralston action starting from the massive Proca electrodynamics in Riemannian spacetime and performing the minimal coupling with torsion.We end up with an action which contains the Nodland Ralston action without breaking the gauge invariance.This mechanism however gives a photon a mass generated by the nonlinear torsion terms.The torsion vector is along the cosmic rotation axis and interacts with the massive photon.This method which breaks conformal invariance allow us to determine a primordial torsion of the order 10 −29 eV from the well-known photon mass limits.
