Legal arrangements rest on behavioural, cognitive, social, and other assumptions regarding their role and function in society and the legal system. The identification and subsequent evaluation of these assumptions is an important task for legal scholarship. In this article, we focus on the identification and categorisation of these assumptions, providing conceptual distinctions and methodological guidance. We distinguish between assumptions about the value(s), norm(s), or interest(s) underlying a legal arrangement, which can be legal or non-legal, and assumptions about the relationship between the legal arrangement and its underlying value(s), norm(s), or interest(s), which can be logical, causal, or contributory. Regarding the identification, we consider explicit references and inference to the best explanation and theory-driven evaluations as possible methods. Inference to the best explanation, we posit, functions as a manner of reconstructing the theory that the person(s) creating a legal arrangement had in mind regarding the place and function of that legal arrangement in society. Given this, we offer a step-by-step approach to reconstructing this theory in use, drawing from theory-driven evaluations and its sources in the social sciences. These distinctions and guidelines can contribute to understanding the context and untangling the complexities involved in identifying the assumptions that underlie legal arrangements.

Developing the capacity for moral judgment is an essential professional competence for lawyers. What teaching and learning activities in the law curriculum can be used in order to contribute to students’ moral reasoning and moral judgment? Four teaching methods were tried out in the period 2019 to 2021 at the Utrecht University School of Law: teaching methods that either work with (hypothetical) dilemmas (I); in-class reflection papers (II); experiential learning based on own experiences in a simulation situation (III); or clinical teaching in a real law firm (IV). The effects of these methods on the development of moral reasoning were measured using the Defining Issues Test (DIT). Additional information on the effectiveness and utility of the method was gathered using semi-structured interviews with teachers. The DIT results were compared at the beginning and at the end of the courses and related to the teaching methods. This article presents the outcomes of this study and formulates some recommendations for further research on the topic.

Many doctrinal legal research questions require making use of other academic disciplines or perspectives. This article explains the relevance of legal philosophy for doctrinal research projects. Often legal research questions have conceptual or evaluative dimensions that presuppose philosophical understanding. For research on the concept of democracy, the function of constitutional rights, or the possible introduction of a referendum in the Netherlands, questions of a philosophical nature need to be answered. Legal philosophy can supplement and enrich doctrinal research in various ways. In this article, we present seven purposes that legal philosophy may serve in the context of a doctrinal research project: conceptual clarification, exposition and reconstruction of fundamental normative principles and values, theory building, providing creative perspectives, structural critiques, evaluation, and recommendations. For each objective, we illustrate how to use relevant philosophical methods. Thus, this article complements our earlier publication ‘Legal Philosophy as an Enrichment of Doctrinal Research – Part I: Introducing Three Philosophical Methods’.¹x http://www.lawandmethod.nl/tijdschrift/lawandmethod/2020/01/lawandmethod-D-19-00006.
