The real legacy of american legal realism

The most important promise of the legacy of legal realism is its robust understanding of law, which is irreducible to one or another more or less familiar jurisprudential school, as a set of institutions distinguished by the difficult accommodation of three constitutive yet irresolvable tensions: between power and reason, between science and craft, and between tradition and progress. This article defends this view through a critical analysis of Brian Leiter's ambitious and provocative account of legal realism, whose legacy he describes as naturalised jurisprudence. I argue that Leiter understates the realist indeterminacy critique of pedigreed sources, misses the realist distinction between doctrine (or pedigreed sources) and law, and errs in classifying legal realists as tacit hard positivists. By studying these mistakes and refining his naturalistic claims, I reveal why Leiter must also be incorrect in reducing legal realism to a descriptive theory of adjudication. Leiter's account obscures the real legacy of legal realism.
