  We propose an analysis of LEP constraints on radiative neutralino decays into
a light gravitino, based on the plane of the Higgs mixing parameter mu and the
SU(2) gaugino mass M_2. The preliminary LEP 2W constraints in the (mu, M_2)
plane are considerably stronger than for supersymmetric models in which the
lightest neutralino is stable. A significant portion of the parameter space in
which chargino or selectron decay into a final state containing a light
gravitino could provide an interpretation of the CDF ee gamma gamma + E_T,miss
event can now excluded by the preliminary LEP 2W data.
