The parity-non-conserving. V-A form of Fermi interaction is derived from a principle of invariance under a continuous group of transformations, in analogy wlth the ordinary gauge-invariance derivation of the minimal electromagnetic interaction of charged particles. This assumption is a stronger restriction on the form of Fermi interactions than that invoked by Sudarshan and Marshak, Gell-Mann and Feynman, and Sakural, and leads to additional predictions that are subject to experimental check. If these transformations were symmetry transformations of the entire Lagrangian, then the BETA - and mu -decay coupling constants would be precisely equal. The implications of extending this Fermi gauge invariance to a group depending on space-time functions is discussed. The possibility that Fermi interactions involving change of strangeness are unallowed is considered, and the results of assuming a universal Yukawa V-A parity-non-conserving interaction are tabulated. Such a Yukawa interaction, involving one new coupling constant, leads to reasonable K-meson and hyperon decay rates and allows pi -meson decay into mu + nu without any appreciable decay into e + nu .
