The　quantal　symmetry　property　in　the　CP1　non-linear　sigma　model　with　Abelian　Maxwell　-　Chern　-　Simons　(AMCS)　term　in　2　+　1　dimensions　is　studied.　In　the　Coulomb　gauge,　the　system　is　quantized　in　the　Faddeev　-　Senjanovic　(FS)　path-integral　formalism.　The　canonical　Ward　identities　for　proper　vertices　under　local　gauge　transformation　are　derived.　Based　on　the　quantal　symmetries　of　a　constrained　Hamiltonian　system,　the　fractional　spin　at　the　quantum　level　of　this　system　is　also　presented　as　those　of　the　system　without　Maxwell　term.
