Legal metamorphoses between persons/things have been recurrent in history: Persons can become things, animals can turn into persons, and even ghosts can obtain personhood in the legal domain. Law would work then as a form of magic, a powerful instrument to create realities that, although fictional, have very real effects. Drawing on anthropology and legal scholarship, I will show the links between law and magic. In this endeavor, I examine two groups of legal cases from Argentina where people and animals respectively obtained personhood through the magic of law. First, I analyze the so-called human rights trials that are judging the crimes of the last military dictatorship (1976–1983), and I argue that these are working to restore the legal personhood of those who enforcedly disappeared. Second, I examine a series of judgments that have recently ruled—for the first time in modern legal history—that orangutans, chimps, and elephants are “nonhuman persons.” I conclude this Paper by contrasting legal magic with shamanic practices. I argue that even if these two are linked, it is possible to find in some forms of shamanism a different way of framing the relationship between persons/things that can offer an alternative (to) law.
