  A recent paper by Peshkin [1] has drawn attention again to the problem of
understanding the spin statistics connection in non-relativistic quantum
mechanics. Allen and Mondragon [2] has pointed out correctly some of the flaws
in Peshkin's arguments which are based on the single valuedness under rotation
of the wave functions of systems of identical particles. We examine carefully
the claim that is made in the title of [2] that there can be ``no
spin-statistics connection in non-relativistic quantum mechanics''. We show
that we can derive the spin statistics connection for non-relativistic quantum
field theories which have equations of motion of the Hamiltonian type based on
SU(2) invariance of the Lagrangian. The formalism and machinary of
non-relativistic quantum field theory as opposed to usual quantum mechanics is
necessary for constructing our proof.
