It is shown that the π0-pole term predicts a large difference by nearly two to three orders of magnitude for the branching ratio of the Σ0→Λ0+2γ decay mode, depending upon the value of the Σ-Λ relative parity. It is further argued that this difference is not masked, even if we include other diagrams. It is thus suggested that a study of the branching ratio of the Σ0→Λ0+2γ decay may serve to determine the Σ-Λ relative parity.
