Third PILAGG Seminar – 16th October – Global Law and Interdisciplinary Inquiry, Alexander Panayotov


The interdisciplinary collaboration between law and social science has often been hailed as a promising avenue for studying law and globalization. In reality, however, this collaboration has been stymied by diverging disciplinary discourses, conflicting research practices, and incompatible methods for evaluating scholarly findings. I elucidate the possibility conditions for a productive engagement between law and social science. After laying out the obstacles to this engagement, I offer arguments for reconciling the differences.

Specifically, the “Legalization in World Politics” (LWP) framework is used as a starting point to evaluate both the strengths and weaknesses of the social science approaches to law. I contend that both law and social science can engage in a productive cross-fertilization by identifying common unifying themes such as jurisdictional politics. This theme combines social scientists’ strive for generalizations and legal scholars’ fine-grained analysis of complex technical legal issues. The paper defines jurisdictional politics, lays out a generic model for its constitution, and positions it in a transnational context. In this context, I also investigate the promise of deploying social mechanisms to explain both the process of legal change and the emergence of legal order. Four such mechanisms are identified: assertion, diffusion, layering, and conversion. Subsequent examples illustrate their operation. Hopefully, this contribution will stimulate scholars to partake in interdisciplinary work and formulate alternative strategies for exploring their research puzzles.

First PILAGG meeting of 2015-2016 seasson!!! (UPDATE)

The new seasson of PILAGG is going to be launched. We will discuss on Horatia Muir Watt’s framing paper.HMW-Framing paper PILAGG 2015-2016

Discussant: Loïc Azoulai (SPLS)

What are the specific insights of the discipline of the conflict of laws in respect of some of the most significant issues which challenge contemporary legal theory, in its attempts to integrate the radical changes wrought by globalisation in the normative landscape beyond (framed outside, or reaching over) the nation-state. Indeed, remarkably, these changes have brought complex interactions of conflicting norms and social systems to the center-stage of jurisprudence. This means that the conflict of laws has a plausible vocation to contribute significantly to a “global legal paradigm” (Michaels 2014), that is, a conceptual structure adapted to unfamiliar practices, forms and “modes of legal consciousness” (Kennedy 2006). Conversely, however, private international legal thinking has all to gain from attention to the other legal disciplines that have preceded it in the effort to “go global”. Thus, it needs to undergo a general conceptual overhauling in order to capture law’s novel foundations and features. In this respect, it calls for an adjustment of its epistemological and methodological tools to its transformed environment. It must revisit the terms of the debate about legitimacy of political authority and reconsider the values that constitute its normative horizon. From this perspective, the ambition of this paper is to further the efforts already undertaken by various strands of legal pluralism, as an alternative form of “lateral coordination” in global law (Walker 2015), towards the crafting of a “jurisprudence across borders” (Berman 2012). Societal constitutionalism (Teubner 2011), which has explicitly made the connection between transnational regime-collison and the conflict of laws, provides a particularly promising avenue for unbounding the latter, which might then emerge as a form of de-centered, reflexive coordination of global legal interactions.

 When? On Friday 25 September at 2.30pm

Where? At Sciences Po Law School, 13 rue de l’Université, 75007 Paris, Salle de réunion (4th floor).
