A 1986 experiment involving a two-particle entangled system is analyzed, and it is shown that: (1) the measurement results of that experiment are in contradiction to the discrete degenerate form of the quantum measurement postulate (DDQMP) and (2) the measurements done in the experiment are of the positive operator valued measure (POVM) type. Thus there exist POVM measurements which contradict the DDQMP. A modification to the DDQMP is provided which agrees with the experimental results. The modified DDQMP is then applied to a proposed experiment involving a three-particle Greenberger-Horne-Zeilinger state.
