  Relations between the form factors that parametrize the hadronic matrix
elements, in spectator decays of heavy mesons, have been derived by Stech
within the constituent quark model. In here, we examine these relations using a
slightly modified description of the meson states. We find new and very general
relations for some of the form factors. For the other form factors, we obtain
small modifications to the relations previously derived by Stech, in the case
of heavy-to-light transitions.
