We consider the production of [tau] pairs by electron-positron colliding beams at the maximum cross section near the threshold. At this energy [tau] pairs are produced mostly in the [ital s] wave which implies that the spin of the [tau] pairs is almost always pointing in the beam direction independent of the production angle. When both electrons and positrons are longitudinally polarized in the same direction, for example, 90%, one can obtain [tau] pairs with 99% polarization in the direction of the polarization vectors of the incident beams. Tests of [ital CP] violation and study of the structure of weak interactions using such polarized [tau] pairs is discussed.
