We search for pair production of doubly charged Higgs particles (H{sup {+-}}{sup {+-}}) followed by decays into electron-tau (e{tau}) and muon-tau ({mu}{tau}) pairs using data (350 pb{sup -1}) collected from pp collisions at {radical}(s)=1.96 TeV by the CDF II experiment. We search separately for cases where three or four final-state leptons are detected, and combine results for exclusive decays to left-handed e{tau} ({mu}{tau}) pairs. We set an H{sup {+-}}{sup {+-}} lower mass limit of 114(112) GeV/c{sup 2} at the 95% confidence level.
