We consider one-loop radiative corrections from Lorentz- and CPT-violating extended QED to address the specific problem of finding explicitly an effective action describing the amplitude of photon triple splitting. We show that it is not possible to find a nonzero photon triple splitting effective action, at least by using the derivative expansion method (at zero external momenta), up to leading order in the Lorentz- and CPT- violating parameter.
