摘要：
Based on the global canonical symmetry of the path integral in phase space, the quantal conserved angular momentum and BRS charge for non-Abelian Chern-Simons (CS) theories have been derived. The possibility of the occurrence of fractional spin properties for non-Abelian CS theories cannot be always preserved at the quantum level.
