On the Interpretability of Law: Lessons from the Decoding of National Constitutions

Published online by Cambridge University Press:  09 October 2012

Abstract

An implicit element of many theories of constitutional enforcement is the degree to which those subject to constitutional law can agree on what its provisions mean (call this constitutional interpretability). Unfortunately, there is little evidence on baseline levels of constitutional interpretability or the variance therein. This article seeks to fill this gap in the literature, by assessing the effect of contextual, textual and interpreter characteristics on the interpretability of constitutional documents. Constitutions are found to vary in their degree of interpretability. Surprisingly, however, the most important determinants of variance are not contextual (for example, era, language or culture), but textual. This result emphasizes the important role that constitutional drafters play in the implementation of their product.

1 Such efforts to clarify language at the end of constitutional negotiations are not unprecedented. The framers of the US Constitution created a Committee on Style to ‘revise the style of, and arrange, the articles which have been agreed to by the House’. The Committee, however, made substantive proposals, such as to include a bill of rights, and most of its suggestions were rejected.

7 One might argue that it is the interpretability of the constitutional order that really matters, not the interpretability of the constitutional text. By this logic, our whole enterprise would seem trivial. We disagree. Not only is it impractical to assess each countries’ constitutional order over time, but more importantly, the constitutional text is the foundation of the larger constitutional order. As a result, one can learn much about the constitutional order from a systematic study of constitutional texts. At the very least, whether the interpretability of the constitutional text or the constitutional order should be given priority is an empirical question that requires a firm understanding about the causes of both.

30 We have employed a set of graduate students (both in law and political science) and highly competent undergraduates to assist in the data collection. In total, 97 individuals have worked with us as coders, and of this group, 18 have become reconcilers. The coders and reconcilers include a number of graduate students from foreign countries, and native speakers of more than a dozen languages.

31 We exclude codings of slightly more than 250 constitutions that have not yet been reconciled.

32 For the most part, the rulings are treated as settled law, although on several occasions a principal investigator has overturned a prior decision, an action which has then precipitated the retroactive coding of affected cases.

41 We include the Bill of Rights as a single amendment, since all ten amendments included in the Bill of Rights were passed at the same time.

42 Some aspects of context are measured at the country level and some at the constitution level.

44 Equation 3 suggests that we use a three-level model, with random intercepts for both the country and the constitution. We do not report the results from a three-level model, because when we did estimate such a model, the country-level random-intercept was statistically insignificant.

45 The language variables are also jointly insignificant (Pr(χ 2 = 0) = 0.87).
