Gadamer’s attitude to Collingwood was marked by ambivalence: while promoting the Englishman on the one hand, Gadamer claimed on the other that the fundamental dimension of “hermeneutical mediation” had simply escaped him. In this paper, I aim both to assess Gadamer’s debt to Collingwood and the prima facie strength of his objections. First, I reconstruct steps by which ideas of Collingwood found their place in Gadamer’s hermeneutics in the 1950s, including the central “axiom of all hermeneutics”: the thesis that “we can understand a text only when we have understood the question to which it is an answer.” Second, I examine Gadamer’s main objections to Collingwood, the first one being based on a misunderstanding of Collingwood’s stance, while the second one hits home, and I argue in the final section that at issue here is Collingwood’s claim that it is possible to rethink exactly the same thought as that of, say, an historical agent, while Gadamer holds precisely the opposite view, that this is never possible.

The purpose of this chapter is to discuss the role of judicial dialogue between international courts in the interpretation of customary international human rights law. Judicial dialogue refers to international courts’ spontaneous practice of referencing other international courts’ decisions or international instruments that are outside the international court’s own judicial system. International courts engage in this practice in order to both identify rules of customary international human rights law and reach common interpretations on the meaning and scope of norms protecting human rights. Through the analysis of international courts’ case law, this chapter discusses the impact of judicial dialogue consisting in cross-references to legal norms and judicialdecisions on the interpretation of rules protecting human rights, especially when judges use case law from other courts in support of their interpretation.

Effectiveness and efficiency in judicial decision-making are the most important objectives of any court. While this concerns primarily the final decisions that are rendered, it is also relevant to the judicial process and the legal reasoning that a court or tribunal carries out to reach its decision, in order to ensure continuity and coherence. Traditional understandings of the international judiciary have seen the judges’ role as one where they discover and declare the law by applying it at face value to the legal issues that have arisen within the case, thereby achieving effectiveness through what is said to be direct and clear application of the law. This sits rather uneasily with the identification of customary international law (CIL), which is by its very nature unwritten and established by identifying evidence of state practice and opinio juris. The aim of this chapter is to examine instances of judicial activism in the decision-making of international courts and tribunals during the determination and application of CIL and how that allows for either judicial effectiveness or ambiguity.

The uncertain character of customary international law (CIL) has been discussed time and time again among academics and practitioners. To most of them, the uncertain character of CIL entails a twofold defect: first, uncertainty is perceived with respect to the identification of the rule, since we may not know whether there is a valid legal rule; and second, uncertainty is perceived with respect to the content of the rule, since we may not know the precise meaning of the rule. Yet, what seems to be missing from the entire discussion is the mechanism by which CIL functions. Although a number of theories have been formulated, there are no persuasive answers that would explain when and how changes in CIL occur. In other words, the dynamics of CIL, as the driving force behind its evolution remain essentially unexplored. Providing answers to these questions requires an in-depth understanding not only of the structure of CIL but also of the processes that occur in and out of CIL during its operation as a social system. This chapter uses complexity science to describe the functioning of CIL and explore CIL’s construction as a social system.

The interpretation of unwritten norms is fraught with difficulty, as the boundaries between the existence of a norm and the determination of its content can become blurred. Interpreters may return to the evidence of the norm’s existence in order to determine its content or it may be that interpretation itself is part of the constitutive process of unwritten norms. This confusion is exacerbated by a lack of established methods and procedures for the interpretation of unwritten international law, which includes not only custom but also general principles of law. While it is commonplace to speak of custom and general principles under the umbrella of ‘general international law’, it is unclear whether questions of interpretation are to be approached in the same manner for both categories of norms or whether custom and general principles may assist in the interpretation of one another. The central objective of this chapter is to examine the interactions between these two categories of norms in the context of interpretation. More specifically, it considers whether general principles of law may play a role in the interpretation of customary rules.

In its case law the International Court of Justice has repeatedly suggested the idea that rules of customary international law (CIL) do not operate in a vacuum but, instead, are to be understood against the background of other rules of the international legal system. This observation, although somewhat unsurprising, shows that the sources of international law exist in close interconnection – something that is also visible if one looks at the rules of interpretation contained in Article 31 of the Vienna Convention on the Law of Treaties. Accordingly, ‘any relevant rules of international law applicable in the relations between the parties’ must be taken into account, together with the context, when interpreting treaty provisions. The question addressed in this chapter is whether or not the same can be said of the interpretation of customary rules. In other words, if we look at the practice of international courts and tribunals, is it possible to reach the conclusion that CIL rules, too, must be interpreted with the cognizance of any relevant rules of international law applicable between the parties?

The process of identifying and interpreting norms of customary international law, while appearing to be primarily based on an inductive analysis of state practice and opinio juris, is sometimes a deductive exercise based on logic and reason. Logic permeates every decision in international law. Logic manifests itself inherently throughout the process and can be identified in all steps of reasoning in identifying, interpreting and applying customary international law. Logic, however, can constitute the application of either an inductive or deductive inference. This chapter focuses on situations in which the International Court of Justice (ICJ) and the Permanent Court of International Justice (PCIJ) applied a deductive approach, identifying or interpreting norms of customary international law without seeming to consult state practice and opinio juris. Specifically, it considers whether norms that can be reasonably inferred or deduced from existing rules, or that are simply logical for the operation of the international legal system, can be identified as norms of customary international law under a complementary, supplementary or distinctive interpretive approach.

When faced with the inevitable task of interpreting customary international law (CIL), what should a court do and what should it consider? Should it engage in an ‘inductive’ process of sifting through available evidence of state practice and opinio juris or a deductive process designed to reason logically from principles embedded in the rule? Should the court invoke something like the rules of treaty interpretation with their focus on good faith, ordinary meaning, context, and object and purpose? International law doctrine falls short here. Figuring out how to interpret and apply custom requires a theory of custom, a focus on the normative stories we tell. This reveals that there is not just one story explaining why custom should be a source of law, but multiple stories. What we call ‘custom’ may represent or draw from at least three different sources of law: Negotiated Law, Legislated Law and Adjudicated Law. This chapter aims to show that the non-treaty rules derived from each draw on different sources of legitimacy, operate according to different logics, dictate different methods of interpretation, and favour different methods for resolving disputes.

Customary international law (CIL) is particularly vulnerable to the accusation that it is no more than ‘mere assertion’, a creation of the courts, if not downright fantasy. Yet it is in CIL that one finds the strongest claim to objectivity in international law. It is expressed in the doctrine that one of the elements of CIL is state practice, which represents the ‘objective’ element of CIL. It is thought to supplement the ‘subjective’ or ‘psychological’ element of CIL: opinio juris. This chapter argues that the notion of state practice as a set of ‘material facts’ that should be ‘identified’ and from which customary norms can be ‘induced’ is grounded in obsolete epistemology. The identification of state practice is more adequately described as a selection of what deserves to be counted as state practice. It is argued that the starting point for this selective process is opinio juris. Opinio juris does not come after the fact, as a subjective feeling of obligation that is superadded to a set of otherwise objective facts. Opinio juris is the indispensable conceptual framework without which habits and usages cannot even be ‘seen’ as state practice.

Interpretation is ubiquitous in everyday life. We constantly interpret a variety of objects. Interpretation is central to the practice of international law, too. Arguing about international law’s content is the everyday business of international lawyers, and this often includes arguing about the existence and content of norms of customary international law (CIL). Although a number of scholars recognise that CIL can be interpreted, disagreements remain as to the precise methods and extent of CIL interpretation. Such disagreements are born of a common concern to secure competently made, coherent and accurate interpretations of CIL, given the latter’s non-textual nature. This chapter aims to explore in a preliminary manner two related questions regarding CIL interpretation: (1) Is it necessary, or even possible, to strive towards coherence in the interpretation of CIL? (2) Are there any possible indicators of (in-)coherence in that respect? Providing answers to these questions depends on how one understands coherence in the first place, including its relation to legal reasoning. A substantial part of the chapter will therefore deal with that as well.

Chapter 8 examines regulatory rules, beginning with an examination of written rules. It underlines the inescapability of interpretive uncertainty and considers ways in which that uncertainty can be addressed, including varying the precision of rules, how they are specified, the publication of interpretive ‘guidance’ (sometimes called ‘soft law’) and the delegation of detailed standard-setting to ‘technical experts’.

This chapter advocates an ethic of “symmetric interpretation” as a solution to the challenges outlined in Chapter 1. To prevent undue politicization of constitutional law, judges should favor, when possible, constitutional understandings that are “symmetric” in the sense of conferring valuable protections across both sides of the nation’s major political and ideological divides. By the same token, they should disfavor understandings that frame constitutional law as a matter of zero-sum competition between rival partisan visions. Favoring symmetric understandings in this sense will not always be possible. When it is possible, however, favoring symmetry may provide a point of common orientation for judges with differing policy preferences and interpretive outlooks. Reflecting this approach's inherent appeal, an inchoate preference for symmetry is already evident in judges’ opinions, oral argument questions, and reasoning.

This chapter advances theoretical reasons to support symmetric interpretation. First, favoring symmetry accords with the Constitution’s character as a comparatively terse, “framework” document focused on establishing democratic procedures rather than definitive policies. Second, an ethic of symmetric interpretation accords with widely accepted features of judicial role-morality. Finally, symmetric interpretation accords with the framers’ own constitutional aspirations and interpretive methods. Multiple widely accepted theoretical considerations in constitutional law thus support preferring symmetric understandings when possible.

Originally established by “we the people,” as its preamble majestically states, the Constitution belongs to us all. But Americans increasingly treat it as the property of one political faction or the other. In keeping with their own preferences, conservatives interpret the Constitution to protect religion, limit gun control, and obstruct administrative governance while allowing state-level regulation of moral questions like abortion. Progressives see a mirror-image constitution that advances social justice, confers broad federal power, and allows flexible administrative regulation while at the same time limiting state and local police authority and guaranteeing sexual and reproductive autonomy. As national politics have grown ever more divided and polarized, preventing either side from implementing its goals through federal legislation, both coalitions have dreamed of capturing the courts and implementing their vision instead through constitutional interpretation. A document that should be a source of unity and shared commitments has become a vehicle for extending political conflict.

Brennan Breed’s “The Reception History of Isaiah: Unsealing the Book” takes a single theme attested in just a few verses (Isa 8:16; 29:11; and 30:8) and shows how it has been reinterpreted by readers ceaselessly across the centuries, all the way from later biblical authors to modern times, in response to everything from sectarian divisions to African-American slavery to the trauma of the Holocaust. These verses refer to the words of the prophet being sealed, especially to those who are ignorant, until the time comes for their meaning to be revealed. This theme brings into focus the ways in which Isaiah has been used polemically, and it also points to the text’s power as a seemingly inexhaustible well of meaning.

The presence of race is seemingly obvious in American literature. Yet many readers either misunderstand the role it plays or simply don’t pay attention to it as a subject worthy of analysis. Written in language accessible for both the undergraduate and graduate classroom, this chapter targets such misapprehension. It first makes a series of arguments diagnosing the phenomenon of racial misapprehension, including the way whiteness purports to racelessness, the overreliance on a Black–white binary, the multiple different meanings of race across time, and the influence played by race and racialization within histories seemingly distanced from racial identity. Second, it suggests methods for apprehending and interpreting racial meaning, focusing specifically on genres and tropes. Both constitute key pathways through which race enters literary texts and through which literary texts, in turn, come to inform how their readers think about and perceive race.

Over the past three decades norms research has become a subfield that matters beyond the boundaries of International Relations (IR). Like other such generative processes this subfield’s path is marked by debates over conceptual and methodological preferences. This book argues that irrespective of how we understand these divides, the critical question for today’s norms researchers is how have our understandings of norms developed over this period? To address this question this book brings together a range of junior, mid-career, and senior scholars, working at the leading edge of norm research, across a diversity of issues and subfields, and using different epistemological perspectives. Two lenses feature in this endeavour: the first considers the history of norm research as a series of three distinct and theoretical moves, and the second examines the potential of practices of interpretation and contestation (which we term the ‘interpretation-contestation framework’) as a way of bringing together a range of theoretical tools to understand norm change, evolution, and replacement. In short, this book focuses on the past trajectory of the field to argue that norm research continues to hold significant potential and promise for theorising within IR and studying current issues and problems.

Over the past two decades, we have seen a significant shift in the norms literature away from the idea that a norm reflects a fixed and universally accepted shared understanding to notions that any norm – even those which appear to be widely institutionalised in international organisations of global governance – remains subject to contestation and interpretation at multiple sites in world politics. In this chapter, we take up the challenge of studying these diverse types of norms and their meaning, use, and role in practice. We begin by returning to the three moves laid out in the introduction and use as a vignette the forced landing of Ryanair Flight 4978 in Belarus in May 2021 to explore how each of these three moves can explain these events. We then draw out three sets of conclusions from the book, focusing on the process of contestation. We end by noting that the distinct approaches to norm research developed over the past thirty years do speak to one another in meaningful and innovative ways. By focusing on contestation in a holistic way, we can not only understand norms in a unique way but also how they constitute the world.
