Assuming the existence of a gauge boson $X$ which couples to ${B\ensuremath{-}3L}_{\ensuremath{\tau}},$ we discuss the present experimental constraints on ${g}_{X}$ and ${m}_{X}$ from $\stackrel{\ensuremath{\rightarrow}}{Z}{l}^{+}{l}^{\ensuremath{-}}$ and $\stackrel{\ensuremath{\rightarrow}}{Z}\overline{f}fX(f=q,{\ensuremath{\nu}}_{\ensuremath{\tau}},\ensuremath{\tau}).$ We also discuss the discovery potential of $X$ at hadron colliders through its decay into ${\ensuremath{\tau}}^{+}{\ensuremath{\tau}}^{\ensuremath{-}}$ pairs. In the scenario where all three charged leptons (and their neutrinos) mix, lepton flavor nonconservation through $X$ becomes possible and provides another experimental probe into this hypothesis.
