In this paper I discuss and reply to Malcolm Thorburn's important article 'Justifications, Powers, and Authority', Yale Law Journal 117 (2008), 1070. My discussion raises a wide range of conceptual and doctrinal questions about Thorburn's account of justification defences, and about the theory of justfication defences more generally. The paper also trespasses on some broader questions about the nature of law and its relationship to morality.
