Robert Alexy

Alexy's definition of law looks like a mix of Kelsen's normativism (which was an influential version of legal positivism) and Radbruch's legal naturalism (Alexy, 2002), but Alexy's theory of argumentation (Alexy, 1983) puts him very close to legal interpretivism. In The Argument From Injustice, Alexy defends Radbruch's formula that injust or evil laws only lose their legal validity when they deliberately disavow justice and equality. He formulated law's relationship to morality on three theses: • The thesis of incorporation; each legal system contains principles. • The moral thesis; law must be related to a common moral. • The correctness thesis; law must be related to a just moral. At the heart of his theory is the claim to correctness: Law must necessarily claim to be correct, no matter how corrupt, lest it be self-contradictory and fundamentally illogical. As law coerces behaviour and gives individuals decisive reasons for acting, the correctness it claims must also be moral. == Publications ==
