  Lagrange multipliers are present in any gauge theory. They possess peculiar
gauge transformation which is not generated by the constraints in the model as
it is the case with the other variables. For rank one gauge theories we show
how to alter the constraints so that they become generators of the local
symmetry algebra in the space of Lagrange multipliers too. We also discuss the
limitations on using different gauge conditions and construct the BRST charge
corresponding to the newly found constraints.
