The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g\ensuremath-2 is promising to probe a theory involving supersymmetry. We have studied the constraints on the minimal anomaly mediated supersymmetry breaking (AMSB) model using the current data of muon g\ensuremath-2 from Brookhaven. A scenario of seeing no deviation from the standard model is also considered, within a 2\ensuremathσ limit of the combined error from the standard model result and the Brookhaven predicted uncertainty level. The resulting constraint is found to be complementary to what one obtains from \stackrel\ensuremath→bs+\ensuremathγ bounds within the AMSB scenario, since only a definite sign of \ensuremathμ is effectively probed via \stackrel\ensuremath→bs+\ensuremathγ. A few relevant generic features of the model are also described for disallowed regions of parameter space.
