We discuss the possibility of observing non-Fermi-liquid behavior in a system of three coupled quantum dots embedded between two conduction channels. The regime where the system approaches the two-channel Kondo model fixed point in a wide temperature interval occurs when the magnetic ordering competes with Kondo screening. We study the robustness of the system with respect to various perturbations.
