The {tau}{sup {plus_minus}}, highly polarized in the direction of the incident beam, can be obtained from the {ital e}{sup {plus_minus}} collider with the polarized incident {ital e}{sup {minus}} beam. This polarization vector {ital w}{searrow}{sub {ital i}} can be used to construct the {ital T} odd rotationally invariant product ({ital w}{searrow}{sub {ital i}}{times}{ital p}{searrow}{sub {mu}}). {ital w}{searrow}{sub {mu}}, where {ital p}{searrow}{sub {mu}} and {ital w}{searrow}{sub {mu}} are the momentum and polarization of the muon in the decay {tau}{sup {minus}}{r_arrow}{mu}{sup {minus}}+{bar {nu}}{sub {mu}}+{nu}{sub {tau}}. {ital T} is violated by the existence of such a term. {ital CP} can be tested by comparing it with a similar term in {tau}{sup +} decay. One can test whether {ital T} (and {ital CP}) violation is due to the charged Higgs boson exchange by doing a similar experiment for the {mu}{sup {plus_minus}} decay. {copyright} {ital 1996 American Institute of Physics.}
