Abstract
It is well established that majority rule is transitive on some restricted domain and that majority rule is the unique social welfare function satisfying some standard axioms on the universal domain. We prove that majority rule is the unique social welfare function satisfying these axioms on a standard restricted domain over which majority rule is transitive. That is, the only profiles which are used to derive majority rule belong to the restricted domain.
