Abstract
Extending the argument of Gisin we show that the superluminal signals in th e nonlinear quantum mechanics are not a specific difficulty of Weinberg's a pproach, but a generic phenomenon in all nondissipative quantum theories wh ich try to enlarge the unitary motion group while incorporating the traditi onal structures of states and observables. The implications exceed the prob lem of causality. (C) 2001 Elsevier Science B.V. All rights reserved.
