The most import current debate in originalism is between those who believe that judiciary in the course of judicial review can engage only in interpretation and those who believe it can also fill in a “construction zone” when the semantic meaning of a provision runs out. The latter originalists, such as Randy Barnett, Larry Solum and Jack Balkin, make a strong distinction between clear and unclear language in the Constitution. For clear language, judicial review can find a precise original semantic meaning for a provision and there is no need for the judge to consult anything but the semantic meaning. Unclear language, in contrast, creates a construction zone. Within that zone, the judge may appeal to materials other than its original meaning in the course of judicial review.
Mike Rappaport in a recent post poses an important question for the latter camp, wondering how they can really be acting as originalists when engaging in construction. Whatever their theoretical arguments about the necessity of construction, how can constructionists be claiming to deciding a matter based on the Constitution? As Mike lucidly puts it:
If the Constitution is defined as the original meaning of the words in the document – the standard definition of originalists – then the answer appears to be no: the judge who decides a matter in the construction zone is not deciding the matter based on the Constitution. And if the judge is not deciding based on the Constitution, then his decision is not enforcing the supreme law of the land
Mike then notes that one possible response of those who believe in construction is to claim that the “judicial power” gives judges the authority to engage in construction. But in my recent paper, The Duty of Clarity, I show why the Constitution’s understanding of judicial power is inconsistent with construction. There I demonstrate that judicial review was thought to permit judges the authority not to follow a statute only if it were, in Alexander Hamilton’s words, in “irreconcilable variance” with the meaning of the Constitution.
