I argue that transnational law has a formal legal character. To do so, I build on socio-legal scholarship in this domain, but apply a jurisprudential perspective. Specifically, I argue that public fiduciary theory is well-placed to explain the nature of authority evoked by transnational legal orders, as well as their legal features and constitution. This theory claims that the fiduciary character of an organization - that is, its other-regarding purpose and adherence to certain procedural standards - is a necessary feature of its claim to legitimate authority. By addressing these jurisprudential questions, public fiduciary theory contests scholars who deny transnational law’s formal legal character. Ultimately, I argue that despite the private constitution of some transnational lawmaking bodies, and their lack of express public authorization, by fulfilling a transnational fiduciary role they exercise authority that either is or closely resembles public authority. This, in turn, contributes to the legal character of the transnational norms these bodies generate. I use the International Organization for Standardization as an illustrative case study. The implications of this approach include acknowledging that law can exist beyond national or international state regulation, and a denial that coercion is an essential element of law.

What would it mean to say that the public trust doctrine is transnational law? This chapter addresses that question. My main conclusion is that the public trust doctrine is a transnational legal norm but not a transnational legal order. To unpack this claim, I apply concepts from Gregory Shaffer and Terence Halliday’s theory of transnational legal orders (TLOs). My claim is that the public trust doctrine is not a transnational legal order in the way that, say, the rule of law is a transnational legal order. In using the public trust doctrine as a case study of the transnational dimensions of public fiduciary law, this chapter aims to introduce an empirically focused socio-legal approach into conversations about public fiduciary theory. Some scholars have made the conceptual claim that public fiduciary law is transnational in scope. In response, this chapter suggests the need for rigorous analysis of normative settlement (or lack thereof) around public fiduciary norms. To the extent that public fiduciary theory aims to reform transnational law, it must confront the challenges of achieving normative settlement in legal practice. The public trust doctrine’s transnational career is a case study in these challenges.

This chapter explores the concept of ‘entangled legalities’ in the context of pre-modern and (post-)modern localised legal orders: regional, imperial, national, international, transnational and postnational. The first section explores the juridification of the international legal sphere; it contrasts private international law approaches with postnational law approaches, exploring the ways in which the recent postnational shift from hierarchical to heterarchical governance structures in fact leads us back to fundamental questions first posed by (Classical) Roman law. The second section focuses on the striking predominance of ‘strong’ legal norms in current analyses of transnational and postnational legal entanglements. The third section, in contrast, argues for a shift in scholarly emphasis away from ‘strong’ legal norms towards a more explicit focus on the importance of strategic legal argumentation in the constructing localised legalities, via a case study of the multiple juris(dictional)-generative practices revealed in the record of a specific, sixth-century, Roman (Byzantine) dispute settlement: P. Petra IV.39.

This chapter reflects on the diversity of usages of the notion of transnational law in legal scholarship. To do so, it focuses on the lex sportiva as a fruitful empirical field to study in concreto the use of the concept. Indeed, the regulation of international sports is nowadays often referred to as lex sportiva and deemed an example of transnational law. The first part of this chapter retraces how lex sportiva has been used as empirical evidence for a ‘pure’ theory of transnational law, a conception of transnational law as denationalized legal order of a transnational community. The second part will aim to show how lex sportiva can also be used to support an ‘impure’ theory of transnational law, which might better capture the messy process of transnational interactions between multiple levels, norms and institutions that characterizes much of contemporary legal practice.

This chapter maps the law concerning pesticide use in China. It deals with international and regional agreements, international standards, and national and selected provincial and municipal measures. It show the interconnection between transnational law and Chinese law, and emphasises the interconnection between hard law and soft law.As local examples, it examines the provinces of Shandong and Shaanxi and the city of Xi'an.It also shows that, though the law concerning pesticide use in China exemplifies the concept of transnational law order, there are also specific features of Chinese society which affect this area of law.
