## Abstract Let __M__ be an arbitrary structure. Then we say that an __M__ ‐formula __Ο†__ (__x__) __defines a stable set in__ __M__ if every formula __Ο†__ (__x__) ∧ __Ξ±__ (__x__, __y__) is stable. We prove: If __G__ is an __M__ ‐definable group and every definable stable subset of __G__ has __U__ ‐
