N2 - Data collected by ALEPH in the years 1990, 1991 and 1992 have been used to update a previous search for CP violation in the decay of the Z into τ+τ−. The measurement of the weak dipole form factor of the τ lepton has been performed by studying correlations between the τ leptons. No signal of CP violation was found. The weak dipole form factor is found to be · cm, obtained with 19628 identified τ+τ− events. This gives an upper limit on the weak dipole form factor of · cm at the 95% confidence level.
