We study the semileptonic decays of the lowest-lying be baryons to the lowest-lying cc baryons (Xi((t*))(bc) -> Xi((*))(cc) and Omega((t*))(bc) -> Omega((*))(cc)), in the limit mb, m(c) >> Lambda(QCD) and close to the zero recoil point The separate heavy quark spin symmetries make it possible to describe all these decays using a single form factor We also show how these constraints can be used to test the validity of different quark model calculations bb to bc baryon decays are also discussed.
