The requirement of lattice BRS invariance is argued to successfully replace local gauge invariance to any order in a perturbative expansion. In a nonperturbative setting, however, one encounters an obstacle which, on a formal level, exists also in the continuum formulation. The origin of the problem and possible ways to avoid it are discussed.
