A detailed description is given of the analysis of neutral kaons decaying to , based on the complete set of data collected with the CPLEAR experiment. Using a novel approach involving initially strangeness-tagged K0 and , the time-dependent decay-rate asymmetry has been measured. This asymmetry, resulting from the interference between the KS and KL decay amplitudes, has enabled both the magnitude and phase of the CP-violation parameter, , to be measured, with a precision comparable to that of the current world-average values.
