We explore one aspect of the structure of a codified legal system at the national level using a new type of representation to understand the strong or weak dependencies between the various fields of law. In Part I of this study, we analyze the graph associated with the network in which each French legal code is a vertex and an edge is produced between two vertices when a code cites another code at least one time. We show that this network (...) distinguishes from many other real networks from a high density, giving it a particular structure that we call concentrated world and that differentiates a national legal system (as considered with a resolution at the code level) from small-world graphs identified in many social networks. Our analysis then shows that a few communities (groups of highly wired vertices) of codes covering large domains of regulation are structuring the whole system. Indeed we mainly find a central group of influent codes, a group of codes related to social issues and a group of codes dealing with territories and natural resources. The study of this codified legal system is also of interest in the field of the analysis of real networks. In particular we examine the impact of the high density on the structural characteristics of the graph and on the ways communities are searched for. Finally we provide an original visualization of this graph on an hemicyle-like plot, this representation being based on a statistical reduction of dissimilarity measures between vertices. In Part II (a following paper) we show how the consideration of the weights attributed to each edge in the network in proportion to the number of citations between two vertices (codes) allows deepening the analysis of the French legal system.

In Simple Rules for a Complex World, Richard Epstein claims to be focusing on legal simplicity, and on the link between legal simplicity and a legal system less intrusive on individual liberty. It turns out, however, that Epstein's conception of simplicity is itself soaked with the substantive idea of individual liberty. The consequences of this are that the claim that legal simplicity brings individual liberty becomes true by definition, and that Epstein avoids taking on the important and interesting questions of (...) whether and when legal simplicity, more conventionally understood, produces less legal instrusiveness and thus, under Epstein's own conception, more liberty.

Einstein’s razor, a corollary of Ockham’s razor, is often paraphrased as follows: make everything as simple as possible, but not simpler. This rule of thumb describes the challenge that designers of a legal system face—to craft simple laws that produce desired ends, but not to pursue simplicity so far as to undermine those ends. Complexity, simplicity’s inverse, taxes cognition and increases the likelihood of suboptimal decisions. In addition, unnecessary legal complexity can drive a misallocation of human capital toward comprehending and (...) complying with legal rules and away from other productive ends. While many scholars have offered descriptive accounts or theoretical models of legal complexity, most empirical research to date has been limited to simple measures of size, such as the number of pages in a bill. No extant research rigorously applies a meaningful model to real data. As a consequence, we have no reliable means to determine whether a new bill, regulation, order, or precedent substantially effects legal complexity. In this paper, we begin to address this need by developing a proposed empirical framework for measuring relative legal complexity. This framework is based on “knowledge acquisition”, an approach at the intersection of psychology and computer science, which can take into account the structure, language, and interdependence of law. We then demonstrate the descriptive value of this framework by applying it to the U.S. Code’s Titles, scoring and ranking them by their relative complexity. We measure various features of a title including its structural size, the net flow of its intra-title citations and its linguistic entropy. Our framework is flexible, intuitive, and transparent, and we offer this approach as a first step in developing a practical methodology for assessing legal complexity. (shrink)

This review of Madhav Kkhosla’s book, India’s Founding Moment, sees his approach as one of “best lights” understandings, that is, an effort to identify and explain the conceptual underpinnings of India’s founding constitution in their best lights. Khosla emphasizes as key the ways in which the constitution’s requirements of full adult suffrage, its intense specificity of language, and its strongly centralized government form, all contribute conceptually to the creation of the democratic citizen of India—a citizen whose rights across the country (...) were secured by a common constitution and central government, whose knowledge of and ability to exercise rights were enhanced by the constitution’s codified approach, and a citizen whose capacities to participate in democratic processes would be developed by the exercise of democratic rights. The review focuses attention on choices about suffrage, comparing India’s with the less inclusionary founding impulses of the United States constitution. It explores nuances of how codification would and would not promote exercises of citizenship rights, noting the importance of adjudication in the construction of the “common knowledge” to which the founders aspired. And the review argues that today, as more illiberal, authoritarian regimes are on the rise, the book’s emphasis on the importance of ideas, words, and common knowledge in constructing liberal, democratic politics is of urgent contemporary importance.
