We establish a sufficient condition for a subgroupofto be discrete, where the pair of isometries (A,B) is-decomposable. This discreteness criterion is a complex hyperbolic version of Gilman’s result in Gilman (Contemp Math 211:261–267, 1997). Furthermore, we give an example to show that one can use our method to ascertain the discreteness of groups that do not pass the classical discreteness test on isometric spheres.
