The path integral for randomly forced incompressible fluids is shown to havean underlying Becchi-Rouet-Stora (BRS) symmetry as a consequence of Galileaninvariance. This symmetry must be respected to have a consistent generatingfunctional, free from both an overall infinite factor and spurious relationsamongst correlation functions. We present a procedure for respecting this BRSsymmetry, akin to gauge fixing in quantum field theory. Relations are derivedbetween correlation functions of this gauge fixed, BRS symmetric theory,analogous to the Slavnov-Taylor identities of quantum field theory.
