Purpose
This paper aims to explore the role of public and private international law and how they are used differently in regulation of global markets. Data were sourced from both primary and secondary materials – journal papers, court decisions, textbooks and international legal instruments to gain insights into the role of law and the varied contexts in which it is used in regulation of markets. In an ordinary sense of the word, law sets operational limits to protect normative values and practices in a state – trade, peace, security, just to mention but a few. However, law cannot be confined to deterring undesired behaviours or to settling disputes, but more importantly, a good law should prevent disputes from happening. Law dictates the way of life of a society and its efficacy often depends on how well it is used to order the proper functioning of the system. International law is the set of rules which govern and foster effective relations of states. The paper explores the chasm between public and private international law, with a view to demonstrate how they are used differently in regulation of markets. Public and private international law encompass norms evolved by multilateral treaties, customs, judicial decisions, model laws and soft law instruments by different oversight bodies governing states and other stakeholders in their relationship with each other. These norms/rules create a platform for interstate cooperation on varied regulatory issues of shared interests. While treaties create a uniform framework of rules in all signatory states, their implementation often depends on individual states willingness to transpose them into national law. Owing to the inherent challenges of public international law (interstate practice), it has become imperative for markets to use rules of private international law. While public regulates the relationship of states and their emanation, private international law helps to bridge gaps in the mainstream international legal systems of states and in so doing enhances their co-existence on overlapping regulatory issues. The engendered trans-national norms will over time generate a positive impact on local sustainability and co-existence of different regulatory domains.
Design/methodology/approach
This paper uses cases studies and experiences of countries to demonstrate the complimentary relationship of public and private international law and how they work in tandem in international legal practice. The paper has also used the varied experiences of states to demonstrate how public and private international law interact in regulation of global markets. Data were sourced from both primary and secondary sources – journal papers, court decisions, textbooks and international legal instruments – to gain insights into the law and the varied contexts in regulation of markets. The case law and experience of states alluded to undertaking this research reflect the complimentary relationship of states for markets to operate effectively.
Findings
The findings of the paper comport with the hypothesis that markets cannot effectively work unless they are pursued within the framework of rules of public and private international law. The paper has alluded to the experience in national jurisdictions and global to highlight the chasm between different regulatory domains for markets to operate effectively. The paper articulates important practical issues relating to public and private international law in regulations of markets.
Research limitations/implications
The practical implication of the paper is that it underscores significant legal issues relating to regulation of markets drawing examples within national jurisdictions and globally.
Social implications
The paper has social implications because markets affect people, jobs and social life in varied ways. It addresses pertinent issues related to the complementarity of public and private international law and how they are manifested in national jurisdictions.
Originality/value
The paper is original because it nuances the interrelationship of public and private international law, teasing out their interaction in regulation of global markets in a distinctive way.
