An object composed of a spinless electrically charged particle and a spinless magnetically charged particle may bear net half-integer spin, but the wave function of two such clusters must be symmetric under their interchange. Nevertheless, a careful study of the relative motion of the clusters shows that this symmetry condition implies the usual connection between spin and statistics.
