• We consider the four-body semi-leptonic decays of charmed mesons. Assuming that the effective Hamiltonian H_w〜J_h<otimes>J_l and that J_h transforms as a 15-dimensional representation of SU(4), we expand the transition amplitude < M_2, M_3|J_h|M_1> in terms of the eigenamplitudes of SU(4). By the help of SU(4) invariance of the amplitudes we obtain sum rules for the various decay rates.
