The recent experimental data on Coulomb breakup of the nucleus {sup 31}Ne are interpreted in terms of deformation. The measured large one-neutron removal cross section indicates that the ground state of {sup 31}Ne is either an s halo or a p halo. The data can be most easily interpreted as the spin of the ground state being 3/2{sup -} coming from either the Nilsson level [330 1/2] or the Nilsson level [321 3/2] depending on the neutron separation energy S{sub n}. However, the possibility of 1/2{sup +} coming from [200 1/2] is not excluded. It is suggested that if the large ambiguity in the measured value of S{sub n} of {sup 31}Ne, 0.29+-1.64 MeV, can be reduced by an order of magnitude, say to be +-100 keV, one may get a clear picture of the spin-parity of the halo ground state.
