We present generalized scattering theory for multi-terminal spin transport insystems with broken SU(2) symmetry either due to spin-orbitinteraction,magnetic impurities or magnetic leads. We derive equation for spincurrent consistent with charge conservation. It is shown that resulting spincurrent equations can not be expressed as difference of potential pointing to{\it non applicability of linear response for spin currents} and as aconsequence equilibrium spin currents(ESC) in the leads are non zero. Weillustrate the theory by calculating ESC in two terminal normal system inpresence of Rashba spin orbit coupling and show that it leads to spinrectification consistent with the non linear nature of spin transport.
