It is often claimed in the media and in political and academic debates that more law nurtures more research, which in turn should generate more information. However, the question researchers are left with is: What does this mean for comparative law and its methods? This paper takes the context of European consumer sales law as an example of the web of rules applicable at both European and national level. In this context, the main idea behind this article is that looking at law and research as data to be built upon and used in further analysis can revolutionise the way in which legal research is understood. This is because current research methods in European consumer sales law fall short of systematically analysing the essential weaknesses of the current regulation system. In this contribution, I argue that the volume of regulation in European consumer law is large enough for it to be considered Big Data and analysed in a way that can harness its potential in this respect. I exemplify this claim with a case-study consisting in the setting up of a Convergence Index that maps the converging effect of harmonizing policies adopted by the European legislator in the field of

Comparative methodology is an important and a widely used method in the legal literature. This method is important inter alia to search for alternative national rules and acquire a deeper understanding of a country’s law. According to a survey of over 500 Dutch legal scholars, 61 per cent conducts comparative research (in some form). However, the methodological application of comparative research generally leaves much to be desired. This is particularly true when it comes to case selection. This applies in particular to conceptual and dogmatic research questions, possibly also allowing causal explanations for differences between countries. This article suggests that the use of an interdisciplinary research design could be helpful, and Hofstede’s cultural-psychological dimensions can offer a solution to improve the methodology of selection criteria.

In the last few decades, we have witnessed the renaissance of Comparative Constitutional law as field of research. Despite such a flourishing, the methodological foundations and the ultimate ratio of Constitutional comparative law are still debated among scholars. This article starts from the definition of comparative constitutional law given by one of the most prominent comparative constitutional law scholars in Italy, prof. Bognetti, who defined comparative constitutional law as the main joining ring between the historical knowledge of the modern law and the history of the humankind in general and of its various civil realizations. Comparative constitutional law is in other words a kind of mirror of the “competing vision of who we are and who we wish to be as a political community” (Hirschl), reflecting the structural tension between universalism and particularism, globalization and tradition.
The article aims at addressing the main contemporary methodological challenges faced by the studies of the field. The article argues that contemporary comparative constitutional studies should address these challenges integrating the classical “horizontal” comparative method with a vertical one - regarding the international and supranational influences on constitutional settings - and fostering an interdisciplinary approach, taking into account the perspective of the social sciences.

The purpose of this article is to investigate whether the notion of an interest should be taken more seriously than the notion of a right. It will be argued that it should; and not only because it can be just as amenable to the institutional taxonomical structure often said to be at the basis of rights thinking in law but also because the notion of an interest has a more epistemologically convincing explanatory power with respect to reasoning in law and its relation to social facts. The article equally aims to highlight some of the important existing work on the notion of an interest in law.

By conducting methodological assessments, legal researchers decide which lines of inquiry are worth pursuing. Two aspects of such assessments are highlighted in this article. The first aspect is to construct promising lines of inquiry. The second aspect is to clarify provisionally the potential of various promising lines of inquiry. Clarifying and calibrating such potential through discourse with fellow researchers are essential. Increased awareness of how legal researchers decide which lines of inquiry are worth pursuing is vital to contemporary discourse about legal methodology.
