PurposeThe paper aims to extend deliberation on legal and political aspects of debate over globalisation versus cosmopolitanism into the field of jurisprudence – philosophy of law. It gives particular attention to questions of the legitimacy of international law and emerging forms of economic governance for business enterprises, soft law, rule of law, accountability and human rights.Design/methodology/approachIn terms of research method, the paper proceeds from normative, as opposed to empirical studies. The paper develops arguments connected with cosmopolitan jurisprudence, a value-based frame of reference for corporate social responsibility. In legal and moral philosophy, normative statements derive from arguments concerning what states of affairs ought to be, how they are to be valued, which things and actions are good or bad. Normative claims contrast with positive (descriptive or explanatory) claims with respect to types of theories, beliefs or propositions. Value is both independent of fact and, at the same time, of an objective nature.FindingsA cosmopolitan jurisprudence frame of reference for economic governance treats human communities as interdependent and takes seriously the human rights obligations and ethical and legal responsibilities of international business enterprises presupposed by international rule of law. In contrast to globalisation jurisprudence, the cosmopolitan philosophy of international law seeks justificatory ground, not only exclusively for traditional forms of centralised governmental authority but also for decentralised, polycentric, private and hybrid public–private forms of authority.Research limitations/implicationsThe paper demonstrates the insufficiency of just describing, as political science and economics does, the emergence of new arrangements for global economic governance. As well, it is insufficient for management theory to propose instrumental strategies for managing various stakeholder interests at play in emerging forms of governance. Efforts of empirical researchers in documenting, classifying and providing empirical analysis of power shifts do not provide moral justifications or groundings of legitimacy from human rights and rule of law. The paper shows how a cosmopolitan jurisprudence standpoint is a fertile theoretical source for addressing such justificatory issues.Practical implicationsIn the context of a rapidly globalising economy, the justification of responsible business conduct across borders and cultures is more and more becoming a pressing practical concern. Increasingly, private actors are operating in authoritative positions, fulfilling governing functions once perceived to be the exclusive domain of nation-states.Social implicationsThe paper suggests that more important than focusing exclusively on descriptive, coercive and instrumental features of law, and seeking some overarching sanctions system that would necessitate pledging allegiance to a global super-sovereign, is cultivating social awareness of the importance of non-instrumental internal dispositions of actors to respect the normative obligatory nature of norms. The intrinsic value of rule of law and human rights provides a vital intellectual pathway for surmounting legitimacy gaps in global economic governance.Originality/valueThe paper breaks new ground by developing a cosmopolitan jurisprudence as an alternative to globalisation jurisprudence. This new articulation of cosmopolitan jurisprudence serves to provide analysis of philosophical justifications for emerging soft law syndicates that purport to establish obligations for business enterprises and other participants towards soft law regimes touching upon sustainability and human rights responsibilities.
