Using Noether's theorem, the conservation laws for the general Lagrangian in Einstein-Cartan theory are derived. The general covariant energy-momentum conservation law for the general Lagrangian including torsion is obtained from the general displacement transformation x/sup '//sup ..mu../ = x/sup ..mu../+e/sup ..mu..//sub a/b/sup a/. It is shown that in such a case, the superpotential V/sup ..mu..//sup ..nu..//sub a/ must exist. This result is a natural extension of the theory in Refs. 1 and 2
