Abstract
It is shown that B. W. Lee's relation for nonleptonic hyperon decay can be derived from invariance and , and that the vanishing of requires the additional assumption of invariance. The vanishing of cannot be derived from these symmetries, and since there are no others applicable to weak interactions in , it must result from weak-interaction dynamics. A comparison is made between this theory and those of Cabibbo and Coleman, Glashow and Lee. Mathematical aspects of invariance are discussed in an appendix.
