Abstract
We report a study of τ lepton decays to three charged hadrons and a π

. We use (7.56 ± 0.15)
fb
-1
of data collected with the CLEO III detector at the Υ
(4S)
resonance, which corresponds to a total of (6.90 ± 0.14) × 10
6
τ-pairs. Using both a Ring Imaging Cherenkov (RICH) detector and measurement of specific ionization energy loss (
dE/dx
) for particle identification, we report the first observation of the decay τ
