Abstract : IF THE GROUP PROPERTY (macroscopic causality of the Umatrix (Smatrix computed between finite initial and final times) is postulated, the proof of its unitarity reduces to a most simple verification on the propagation kernels of the theory. The Appendix gives an explicit proof of that property for electro and mesodynamics by means of perturbative expansions, which may be easily generalized. (Author)
