Abstract
We have searched for lepton flavour violation in Z boson decays into l epton pairs using all data collected with the L3 detector during the 1 990, 1991 and 1992 runs on an event sample corresponding to 1 500 000 Z's produced. At the 95% confidence level the upper limits on the bran ching ratio for Z --> emu is 0.6 x 10(-5), for Z --> etau this is 1.3 x 10(-5) and for Z-mutau this is 1.9 X 10(-5).
