We generalize the BRS method for the (finite-dimensional) quantum gauge theory involved in the zero modes of the monodromy extended SU(2) WZNW model. The generalization consists of a nilpotent operator Q such that Qh=0 (h=k+2=2,3,... being the height of the current algebra representation) acting on an extended state space. The physical subquotient is identified with the direct sum \oplusinfh-1n=1ker(Qn)/\im(Qh-n).
