Very interesting article from Professor Krishnakumar

How do canons of statutory interpretation come into being? What qualifies a court’s method of reasoning in a statutory case as a rule or canon of construction? Last week, I wrote about the Supreme Court’s use of the passive voice as an interpretive guide in two somewhat recent criminal cases. Does this mean that we now have a “passive voice” canon of statutory interpretation, at least in criminal cases?

In a recent article, The Hidden Legacy of Holy Trinity Church: The Unique National Institution Canon (forthcoming, 51 William & Mary Law Review __ (2009))—in which I argue that the Supreme Court quietly has employed a “unique national institution canon” to give preferential legal treatment to certain special/unique American entities (Christian churches, baseball, railroads, tobacco, Native Americans)—I touch on this question of how different interpretive methodologies become canons or rules of statutory construction.

One position might be that any time the Supreme Court, as the highest court in the land, uses an interpretive methodology, that methodology becomes a rule or canon of statutory construction. This seems to be the view taken by William Eskridge, Philip Frickey, and Elizabeth Garrett in their Legislation casebook, which contains an appendix compiling “The Supreme Court’s Canons of Statutory Interpretation.” More generally, I would suggest that interpretive methodologies rise to the level of canons of statutory construction when they can lay claim to one or more of the following: (1) frequent use by the Supreme Court; (2) longevity, as when the methodology originated in English courts or long has been listed in Sutherland’s definitive treatise on Statutes and Statutory Construction;(3) grounding in some fundamental tenet of the American legal system (e.g., the Constitution); or (4) fostering consistency with longstanding judicial treatment of particular words or subject matters.
