Larry Alexander, University of San Diego School of Law, is publishing Legal Positivism and Originalist Interpretation in the Revista Argentina de Teoria Juridica (2015). Here is the abstract.
The topic I have been assigned for this keynote address is the relationship between legal positivism and originalist theories of interpretation. Fortunately for me, there is indeed a relationship between these two things, and a strong one at that. Or so I shall contend. My plan is as follows: I shall first give an account of legal positivism. That account will be brief, no more than a sketch, but hopefully not a caricature. But it will be sufficient for demonstrating the relationship between legal positivism and originalist interpretation. After my brief portrayal of legal positivism, I shall turn my attention to originalist interpretation. I shall show why legal positivism supports originalism. And I shall conclude by discussing various objections to originalism, objections that nevertheless can be successfully parried.Download the article from SSRN at the link.
