Gibbard [4) has recently introduced a Pareto-consistent libertarian claim, designed to explicate Sen's Liberal Paradox . The question this paper asks is whether all—or any—social choice functions satisfying Gibbard's claim are worthily of libertarian approval. This paper argues that there is a unique such social choice function.
