In a previous paper [G. Yoneda, Proc. R. Soc. London A445 (1994), 221.], we proved the no-interaction theorem for four particles with the assumption that the (linear and angular) momentum on space-like planes is invariant. In this paper, we assume that the momentum on null cones is invariant and prove that there is no interaction for four particles.
