In this paper I argue that Kant’s political and juridical philosophy justifies a type of normative legal positivism that implies specific notions of law and legal freedom which determine and restrict the sphere of action of judges and jurists. Finally, I defend that, according to Kant’s practical philosophy, the normative connection between justice and law is not supposed to be carried out at the juridical level, as a meta-juridical theory, but at the political one, making it a meta-political theory.
