Communis Opinio and the Methods of Statutory Interpretation: Interpreting Law or Changing Law
Healy, Michael P., William and Mary Law Review
Interpretive methodology lies at the core of the Supreme Court's persistent modern debate about statutory interpretation. (1) Supreme Court Justices have applied two fundamentally different methods of interpretation. One is the formalist method, (2) which seeks to promote rule-of-law values and purports to constrain the discretion of judges by limiting them to the autonomous legal text. (3) The second is the nonformalist or antiformalist method, which may consider the legislature's intent or purpose or other evidence as context for understanding the statutory text. (4) The debate within the current Court is commonly framed and advanced by Justices Stevens and Scalia. Justice Scalia is now famous for his rigid adherence to formalism. (5) Justice Stevens rejects the formalist method, grounded as it is solely on the abstract meaning of statutory text, and employs instead the contextual, nonformalist method that seeks to interpret statutes by reference to the legislature's intent and purpose. (6) This debate about methodology is important because different interpretive results may well follow from the interpretive method that is employed. (7)
This Article provides a context for assessing the Court's debate about interpretive methodology through an examination of the past and contemporary place of the communis opinio canon in cases of statutory construction. The Article begins by describing Brogan v. United States, (8) a recent case in which Justices Scalia and Stevens debated the modern relevance of the ancient canon of communis opinio. (9) The Court, in an opinion by Justice Scalia, employed the formalist method to reject a narrow interpretation of a broad criminal prohibition on making false statements to federal officials. (10) Justice Stevens, invoking the communis opinio canon in his nonformalist dissent, relied on a long-standing practice that had developed under the statute, and was accepted by the Department of Justice and several courts, to impose substantial limits on the scope of the criminal prohibition. (11) Justice Scalia derided this resort to the communis opinio canon, contending first, that the canon simply did not apply to the interpretation of a statutory text and second, that the canon resulted in an error being adopted as law because of its wide acceptance. (12)
The second part of the Article considers the validity of Justice Scalia's claim that the communis opinio canon has no proper application to the interpretation of statutes. The Article addresses the source of the communis opinio canon and a closely related canon in Coke's Institutes, hypothesizes reasons for the articulation of the canons by Chancellor Coke, and considers the easy acceptance and application of the hybridized canon in early American cases. (13) This section will show how the canon, whose value was ridiculed by Justice Scalia, was commonly accepted by American courts. The Article then considers the conventional requirements for the application of the canon and examines how effectively those requirements have constrained the use of the canon in statutory interpretation. (14) Finally, this part of the Article considers the varying interpretive effects that courts have given to the canon when it is applicable. (15) One of these interpretive effects, employed in two notable cases, one decided by Chief Justice Marshall (16) and the other (17) decided five years before the Court famously "endorsed countertextual interpretive techniques" (18) in Holy Trinity Church v. United States, (19) has been to reject the clear, determinate meaning of the statutory text and to accept instead the common practice that developed under the statute. (20) In short, far from being inapplicable to the interpretation of statutes, the communis opinio canon has been employed by the Supreme Court to reach countertextual interpretive results.
Given that the communis opinio canon has been used by the Supreme Court to present interpretations that conflict with the apparent meaning of the text, the last part of this Article considers whether a court acts properly when it accords legal significance, including a determinative effect, to communis opinio. …
