In theories with gauge-mediated supersymmetry breaking, the scalar {tau}, ({tilde {tau}}{sub 1}) is the lightest observable superpartner for part of the parameter space. At CERN LEP 2, the production of such a {tilde {tau}}{sub 1} pair and their subsequent decays give rise to a pair of {tau} leptons plus missing energy from the unobserved gravitinos. The angular distributions of the {tau}{close_quote}s are different from those arising from the production and decay of W pairs, and thus will constitute an interesting signal for supersymmetry. We also consider {tilde {tau}}{sub 1} pair production in the complementary part of parameter space where the lightest neutralino is lighter than the {tilde {tau}}{sub 1}. {copyright} {ital 1997} {ital The American Physical Society}
