Legal Positivism and Natural Law Reconsidered, Again

Abstract

In my article “Legal Positivism and Natural Law Reconsidered” I suggested that we might be able to effect an interesting reconciliation of legal positivism (LP) and natural law theory (NL) by distinguishing two possible LP-NL debates. In particular, I suggested that we should distinguish, within legal philosophy, between theories of legal validity – that is, accounts of the existence conditions for valid law and theories (as I now would put it) of legal interpretation – and theories of adjudication – that is, accounts of how judges should decide cases. We can use this distinction to formulate two possible LPNL debates, one involving legal validity (LP1-NL1) and one involving adjudication (LP2-NL2). NL1 asserts and LP1 denies that the existence conditions for valid law and the theory of legal interpretation ensure that legal standards satisfy true or sound political morality to some significant extent. NL2 asserts and LP2 denies that the content of the correct or justifiable judicial decision must satisfy true or sound political morality to some significant extent. I sketched my own view of the relevant details of the theories of legal validity and adjudication and argued that these claims seem to vindicate LP1 and NL2 and so to allow a kind of reconciliation of LP and NL.
