The hypothesis that massive neutrinos dominate the mass of galactic systems is examined within the context of the theory of violent relaxation of stellar systems. Phase-space considerations, based on the validity of the original version of this theory, require a prohibitively large neutrino mass, m103 eV, if neutrinos are to dominate galactic halos. Similar arguments show that neutrinos can be bound in galaxy clusters if m10 eV.
