We study the decay {omega}{sup -}{yields}{xi}{sup -}{pi}{sup +}{pi}{sup -} in heavy-baryon chiral perturbation theory. At leading order, the decay is completely dominated by the {xi}*{sup 0}(1530) intermediate state, and the predicted rate and {xi}{sup -}{pi}{sup +}-mass distribution are in conflict with currently available data. It is possible to resolve this conflict by considering additional contributions at next-to-leading order.
