Justice-constrained libertarian claims and Pareto efficient collective decisions

This paper discusses justice-constrained libertarian claims that were proposed as a way to circumvent the impossibility of the Paretian liberal. Since most of the results are negative in character, we suggest an alternative route: A requirement on the structure of individual orderings should be combined with the idea that under particular circumstances individual decisiveness should be controlled by higher-order principles.Helpful suggestions from an anonymous referee of this journal are gratefully acknowledged.
