Enforcement of Multilateral Trade Regulation by Non-State Actors - Desirable and Feasible?

Since its inception, the inter-state dispute settlement system of the World Trade Organisation has generally been praised for effectively protecting the rule of law in international trade relations. While the relatively recent dismantling of this system does not necessarily mean the end of the WTO nor of the binding nature of its rules, the current crisis may be a good opportunity to reconsider the role of the rule of law in international trade relations and the ways in which it could further be accommodated. One suggestion, occasionally raised in the past, would be strengthening the enforcement of WTO rules by opening it to private action, either before national courts or through international adjudication. After all, the latter has been widely available to foreign investors covered by thousands of international investment agreements in force for decades. This contribution recalls the reasons behind the current lack of private enforcement of WTO law and argues that developments in international trade relations and experiences with investor-state dispute settlement are likely to work against rather than in favor of its introduction in the foreseeable future. Increased transparency and institutionalisation of non-state actors' role in trade enforcement is therefore recommended instead.
