Signature of spin-state transition at 30K clearly manifests in magnetization, supported by Co L_3,2-edge XAS data on the doped-specimen as consistent with its suppressed T_SST vs. ~150K for pure LaCoO3. Dispersive activation-step {\\Delta}{\\epsilon}'(T_{\\omega})~O(10^2) and relaxation-peak {\\epsilon}\"(T_{\\omega}) reflect the allied influence of coexistent spin-states on the dielectric character.
