  It has been shown in the past that the real part of the e'/e ratio is
particularly sensitive to anomalous gauge couplings that modify the Standard
Model Lagrangian. Due to the loose bounds on these couplings coming from low
energy processes and to the poor sensitivity of hadron colliders to couplings
such as $\Delta g_Z$, it has been argued that anomalous couplings could still
produce an enhancement of Re e'/e bringing this observable closer to the
experimental value obtained by KTeV, NA31 and NA48. The impact of the new
measurements done at LEP2 in these years is discussed and new severe
constraints to this hypothesis are determined.
