This flavour violation can still be reconciled with the experiment if the gaugino mass, $M_{1/2}$, is large enough to yield (through the renormalization group running) a sufficiently small $Δm^2 / m^2$ at low energy. This leads to a gaugino dominance framework (i.e. $M_{1/2}^2\gg m^2$), which permits a remarkably model--independent analysis. We study this possibility focussing our attention on the $μ\rightarrow e,γ$ decay. In this way we obtain very strong and general constraints, in particular $\frac{M_{1/2}^2}{Δm} \simgt 34\ {\rm TeV}$.6 pages, latex+sprocl.sty, 2 figures uuencoded. Based on a talk given by J.M.
