Based on Cohen \& Glashow's very special relativity [A. G. Cohen and S. L.Glashow, Phys. Rev. Lett. {\bf 97} (2006) 021601], we propose an anisotropicmodification to the Friedmann-Robertson-Walker (FRW) line element. Anarbitrarily oriented 1-form is introduced and the FRW spacetime becomes of theRanders-Finsler type. The 1-form picks out a privileged axis in the universe.Thus, the cosmological redshift as well as the Hubble diagram of the type Iasupernovae (SNe Ia) becomes anisotropic. By directly analyzing the Union2compilation, we obtain the privileged axis pointing to\((l,b)=({304^\circ}\pm{43^\circ},{-27^\circ}\pm{13^\circ})\)(\(68\%~\rm{C.L.}\)). This privileged axis is close to those obtained bycomparing the best-fit Hubble diagrams in pairs of hemispheres. It should benoticed that the result is consistent with isotropy at the \(1\sigma\) levelsince the anisotropic magnitude is \(D=0.03\pm 0.03\).
