Nonleptonic decays of hyperons are investigated in terms of the constituent rearrangement (CR) model by assuming i) dominance of 15 and 20'' components of the weak Hamil-tonian in SU(4), ii) universality of d/f ratios and iii) spin non-flip along spectator constituent lines. We analyze the CP invariant CR amplitudes and obtain Σ_+^+ =0 as well as the Lee-Sugawara relation for s-wave decays. It is shown that the contribution of 15 is much larger than that of 20'' in the s-wave decays, while the 20'' component is important for describing the p-wave amplitudes.
