Abstract
A generalized Lagrangian BRST formalism is used to study the quantum s tructure of the simple supergravity, whose classical gauge algebra is not closed. It is shown that in this approach one can naturally introd uce a set of auxiliary fields as certain combinations of ghosts and an tifields, so that the resulting theory has the closed classical gauge algebra.
