“…As we shall see this analysis provides new insights on the community structure of codes we have found in the Part I. So doing, we pursue the process of defining measures of the complexity of the law (Bourcier and Mazzega, 2007b) based on an analysis of its formal structure and content. If we do not have X but the distance matrix D (and consequently the matrix W, the eigen decomposition of which is W =QΛQ (Table 4) are highlighted: the one with twelve codes is in pink (and in italic), the one with eleven codes is in blue (and in bold).…”

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.

“…El nivel de interdependencia de la LIVA pasó de 61 en 1978 a 448 en el primer trimestre de 2016, siendo éste el componente con mayor crecimiento relativo desde que esta ley entró en vigor (en 2016 representa más del 600% que el nivel registrado en la versión de 1978), lo que reafirma el concepto expresado por Bourcier y Mazzega (2007), referente a que la interdependencia entre elementos es lo que mayor ambigüedad genera en la comprensión de una ley.…”

Quartely analysis of the legal complexity of the Value AddeaTax law in the periodo from 1978 to 2016 ResumenSe estudia la complejidad legal a través del modelo de Katz y Bommarito, de la ley del impuesto al valor agregado, desde su versión original publicada en 1978, hasta la versión vigente actualmente (2016). Los datos revelan que la ley se ha vuelto más compleja a través del tiempo, en términos de las variables estructura, entropía e interdependencia; utilizadas en el estudio para conformar el índice de complejidad.Palabras clave: complejidad legal, impuesto al valor agregado.Clasificación JEL: E62. AbstractThrough the Katz and Bommarito's model, we studied the legal complexity of the Value Added Tax Law, from its original version published on 1978,

“…Within the limited scope of our paper, Bourcier and Mazzega propose a vision to represent legal documents using networks, wherein legal articles are nodes connected by edges that represent either "legal influences" or quotations, called "legal selection" [3]. They advocate for content-based measures that account for legal effects produced by normative statements [3].…”

Information systems are increasingly distributed and pervasive, enabling organizations to deliver remote services and share personal information, worldwide. However, developers face significant challenges in managing the many laws that govern their systems in this multi-jurisdictional environment. In this paper, we report on a computational requirements document expressible using a legal requirements specification language (LRSL). The purpose is to make legal requirements open and available to policy makers, business analysts and software developers, alike. We show how requirements engineers can codify policy and law using the LRSL and design, debug, analyze, trace, and visualize relationships among regulatory requirements. The LRSL provides new constructs for expressing distributed constraints, making regulatory specification patterns visually salient, and enabling metrics to quantitatively measure different styles for writing legal and policy documents. We discovered and validated the LRSL using thirteen U.S. state data breach notification laws.
