Non-leptonic decays of Ω--hyperon are discussed in a way consistent with those of octet baryons and K10 meson (see Part I), under the pole approximation in which the parity-conserving and violating effective interactions are assumed to be λ6-like and iλ7-like, respectively. As for the modes of Ω- → Ξ0 + π- and Ξ- + π0, their decay rates are consistent with experiment, and owing to the P-wave dominance their asymmetry parameters are very small as follows:
