Libertarian theories of law

Libertarian theories of law are a family of approaches that build on the classical liberal and individualist doctrines and treat the protection of individual liberty and private property as the organizing purpose of law. Their unifying promise is that the legitimate use of coercion is narrowly bounded: law exists to define and defend property rights, enforce voluntary agreements, and provide redress for aggression.
