We show how a Becchi-Rouet-Stora-Tyutin constant charge can be used to determine the asymptotic states of an anomalous theory when the quantization is defined through a functional integral over all the configurations. We also prove the equivalence of possible alternatives, which correspond to the decoupling of longitudinal modes, to cure nonrenormalization problems appearing in the Abelian (3+1)-dimensional case.
