Last fall many high‐energy physicists felt that the phenomenological description of CP violation in K meson decay was at last complete (PHYSICS TODAY, November, page 73). Now the situation is up in the air again. At the Chicago APS meeting, in a special session on $K^{0}$ decay, two new experiments suggest that we still do not know the value of ${|η}_{00} |^{2}$ the ratio of the two‐neutral‐pion decay rate of $K_{2}^{0}$ to the two‐neutral‐pion decay rate of $K_{1}^{0} .$
