From the abstract for Marc O. DeGirolami, The Traditions of American Constitutional Law (Notre Dame Law Review, Forthcoming):
This article identifies a new method of constitutional interpretation: the use of tradition to inform constitutional meaning. It studies what the Supreme Court means by invoking tradition and whether what it means remains constant across the document and over time. The task is worth pursuing inasmuch as traditional interpretation is pervasive, consistent, and recurrent across the Court’s constitutional doctrine. So, too, are criticisms of traditional interpretation. There are also more immediate reasons to study the role of tradition in constitutional interpretation. The Court’s two newest members, Justices Neil Gorsuch and Brett Kavanaugh, have indicated that tradition informs their understanding of constitutional meaning. The study of traditional interpretation seems all the more pressing to understand certain possible jurisprudential moves in the Court’s future.
The article concludes that when the Court interprets traditionally, it signals the presumptive influence of political, legal, or cultural practices of substantial duration for informing constitutional meaning. Traditional interpretation is thus constituted of three elements: (1) a focus on practices, rather than principles, as informing constitutional meaning; (2) a practice’s duration, understood as a composite of its age and continuity; and (3) a practice’s presumptive, but defeasible, interpretive influence. Traditional interpretation’s emphasis on practices that are given tangible form in a people’s lived experience suggests that it is preferable to speak about politically, legally, and culturally specific traditions rather than an abstracted concept of tradition. Hence, “the traditions of American constitutional law.”
The article identifies traditional interpretation as its own method; shows its prevalence and methodological consistency across the domains of constitutional interpretation; isolates and examines its constituent elements, comparing them against other prominent interpretive approaches; and infers and explains the justifications of traditional interpretation from the doctrinal deposit. While there may be some irony about a claim of novelty in an article about tradition, what this article identifies as new is not the invocation of tradition as such, but the isolation of a recurrent and consistent method—traditional interpretation—adopted by the Court across its interpretive work. It aims to bring to light an overlooked and yet frequently used interpretive practice, and to understand its structure, situation, and purpose within the Court’s constitutional doctrine.
