| Abstract: | The S-matrix is invariant with respect to the variation of any (global) parameter involved in the gauge-fixing conditions, if that variation is accompanied by a certain redefinition of the basis of polarization vectors. Renormalizability of the underlying gauge theory is not required. The proof is nonperturbative and, using the “extended” BRS transformation, quite simple.
