Larry Solum’s “Legal Theory Lexicon” blog posts at his site are exceedingly valuable at introducing basic and advanced legal theory concepts to readers–many of whom are law students and lawyers. His post on originalism is typically excellent, and well worth a read. Of particular note is Professor Solum’s discussion of Original Public Meaning Jurisprudence, which ought to receive specific attention, since it is so pivotal in shaping decisions driven by the conservative wing of the Supreme Court, and of the various federal appeals courts:
The original-meaning version of originalism emphasizes the meaning that the Constitution (or its amendments) would have had to the relevant audience at the time of its adoptions. How would the Constitution of 1789 have been understood by an ordinary adult citizen at the time it was adopted? Of course, the same sources that are relevant to original intent are relevant to original meaning. So, for example, the debates at the Constitutional Convention in Philadelphia may shed light on the question how the Constitution produced by the Convention would have been understood by those who did not participate in the secret deliberations of the drafters. But for original-meaning originalists, other sources become of paramount importance. The ratification debates and Federalist Papers can be supplemented by evidence of ordinary usage and by the constructions placed on the Constitution by the political branches and the states in the early years after its adoption. The turn to original meaning made originalism a stronger theory and vitiated many of the powerful objections that had been made against original-intentions originalism.
This sets the stage for what is sometimes called “the New Originalism” and also is called “Original Meaning Originalism.” Whatever the actual origins of this theory, the conventional story identifies Antonin Scalia as having a key role. As early as 1986, Scalia gave a speech exhorting originalists to “change the label from the Doctrine of Original Intent to the Doctrine of Original Meaning.” The phrase “original public meaning” seems to have entered into the contemporary theoretical debates in the work of Gary Lawson with Steven Calabresi as another “early adopter.” The core idea of the revised theory is that the original meaning of the constitution is the original public meaning of the constitutional text.
Randy Barnett and Keith Whittington have played prominent roles in the development of the “New Originalism.” Both Barnett and Whittington build their theories on a foundation of “original public meaning,” but they extend the moves made by Scalia and Lawson in a variety of interesting ways. For the purposes of this very brief survey, perhaps their most important move is to embrace the distinction between “constitutional interpretation” understood as the enterprise of discerning the semantic content of the constitution and “constitutional construction,” which we might tentatively define as the activity of further specifying constitutional rules when the original public meaning of the text is vague (or underdeterminate for some other reason). This distinction explicitly acknowledges what we might call “the fact of constitutional underdeterminacy.” With this turn, original-meaning originalist explicitly embrace the idea that the original public meaning of the text “runs out” and hence that constitutional interpretation must be supplemented by constitutional construction, the results of which must be guided by something other than the semantic content of the constitutional text.
Once originalists had acknowledged that vague constitutional provisions required construction, the door was opened for a reconciliation between originalism and living constitutionalism. The key figure in that reconciliation has been Jack Balkin, whose influential 2006 and 2007 essaysAbortion and Original Meaning and Original Meaning and Constitutional Redemption have argued for a reconciliation of original meaning originalism with living constitutionalism in the form of a theory that might be called “the method of text and principle.” Balkin has called his position on the relationship between originalism and living constitutionalism “comptibilism,” but it is important to understand that this means that an originalist approach to interpretation is consistent with a living constitutionalist approach to construction.
