It has been claimed by Patil et al., that Ce_{3}Cu_{3}Sb_{4} is the first Ce-based semiconducting ferromagnet. In this paper it is shown, mainly with Hall effect and far infrared spectroscopy that no gap in the excitation spectrum exists, as well above as below the magnetic ordering temperature. A maximum in the resistivity near T_{C} is due to trapped magnetic polarons. The resistivity is an effect of the mobility of the charge carriers. The structure of the magnetic unit cell has been determined with elastic neutron scattering.
