Assume a finite integer l greater than or equal to 2 and a social choice correspondence Phi mapping each (p, Z) into a nonempty subset Phi (p, Z) of Z, where p is a profile of individual preferences and Z is a set of outcomes of cardinality l or more. Suppose that Phi satisfies Arrow's choice axiom, independence of infeasible alternatives, and the Pareto criterion. If the preference domain is the family of profiles of classical economic preferences over the space of allocations of public goods, then Phi is dictatorial.
