We present the first measurement of the correlation between the Z0 spin and the event-plane orientation in polarized Z0 decays into three jets in the SLAC Linear Collider Large Detector experiment at SLAC utilizing a longitudinally polarized electron beam. The CP-even and T-odd triple product SZ(k1×k2), formed from the two fastest jet momenta k1 and k2 and the Z0 polarization vector SZ, is sensitive to physics beyond the standard model. We measure the expectation value of this quantity to be consistent with zero and set 95% C.L. limits of -0.022<0.039 on the correlation.
