Is the current structure of international law still adequate to solve global problems such as child labour? This book argues for more coherence between human rights and trade law, analysing the world trade law compatibility of topical trade measures on (forced) child labour such as the US Tariff Act of 1930 or the proposal for an EU Forced Labour Regulation, mainly under the GATT non-discrimination principles and the policy exceptions clause. Discussing theories such as constitutionalism and pluralism, Franziska Humbert develops the idea of a New Legal Humanism as a cognitive frame for the global legal order.
