Deconstructing blocking statutes : why extraterritorial legislation cannot violate the sovereignty of other states

Abstract

Blocking statutes are national provisions that aim to combat the legal consequences of foreign, extraterritorial legislation. They are often justified by an alleged necessity to protect domestic sovereignty. This article challenges this assumption based on an in-depth discussion of the sovereignty principle and its interplay with the exercise of state power regarding foreign facts. In particular, it shows why a distinction between the law’s territorial scope of sovereign validity and its potentially extraterritorial scope of application is warranted and why, based on these foundations, extraterritorial legislation cannot violate foreign sovereignty. Since Blocking Statutes cannot be understood to protect domestic sovereignty, the article also discusses how they serve to enforce international principles on extraterritorial legislation instead.
