Joseph Story was, above all, a scholarly justice devoted to the expansion of national power and the common law. These aspects of his jurisprudence are highlighted in various documents. As Dane Professor of Law at Harvard University, Story published many of his lectures to educate young lawyers in what he viewed as the proper legal foundations of a republic. The chapter ”Privileges of Citizens—Fugitives—Slaves” in Commentaries on the Constitution of the United States (1833) is an example. In this essay, Story discusses the privileges and immunities clause, the extradition clause, and the fugitive slave clause of Article IV of the Constitution.
