Introducing Regulatory Standards
The three global regulatory standards seen in the disputes studied in this book comprise: a regulatory coherence standard calling for certain relationships between regulatory measures and their purposes, a standard requiring that a regulating State has demonstrated due regard for the interests of other States, and a standard requiring the exercise of due diligence in the exercise of States’ obligations to prevent transboundary harm. These three core regulatory standards consistently characterise the environmental and health disputes in this book, and they appear to be gaining status as global regulatory standards for the future. The appearance of regulatory standards is best understood as an aspect of the functioning of the plural world legal order rather than as a constitutionalisation of this order in a stronger sense. Theories of legitimate authority in plural legal orders cast valuable light on the legitimacy of the emerging standards-enriched international law.
