A search for pair-produced  charged Higgs bosons is performed with the
  L3 detector at LEP using data  collected  at  centre-of-mass  energies
  between 192 and 202~GeV,  corresponding to an integrated luminosity of
  233.2~$\mathrm{pb^{-1}}$.  Decays into a charm and a strange  quark or
  into a tau  lepton  and its  neutrino  are  considered.  The  observed
  events  are  consistent  with the  expectations  from  Standard  Model
  background  processes.  Including  data taken at lower  centre-of-mass
  energies,  lower  limits on the charged  Higgs mass are derived at the
  95\% confidence  level.  They vary from 67.4 to 79.9~GeV as a function
  of the $\mathrm{H^\pm\rightarrow \tau\nu}$ branching ratio.
