A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the \swave Kπ amplitude as a function of Kπ invariant mass. These are compared with results from \Km\pip elastic scattering, and the prediction of the Watson theorem, that the phase behavour be the same below Kη′ threshold, is tested. Contributions from I=\half and I=3\over 2 are not resolved in this study. If I=\half dominates, however, the Watson theorem does not describe these data well.
