Extraterritoriality in Private International Law

Abstract

The paper questions the extraterritorial nature of foreign private law applied by the national law enforcement body in the regulation of cross-border private law relations. In view of the use of common terms “exterritorial” and “extraterritorial” in the framework of international public and private law regulation, it seems necessary to study the extraterritorial effect of foreign private law provisions through the prism of the substantive characteristics of extraterritoriality, formulated in the context of public international law. To this end, the author refers to the definition of extraterritorial jurisdiction as an international legal category and raises the question of how appropriate it is to admit, within the framework of a single definition, “extraterritorial” both the presence and absence of the manifestation of the sovereign will of the state on the territory of which any of the types of jurisdiction of a foreign state is exercised. Taking into account that the manifestation of the extraterritorial jurisdiction of one state in relation to another is realized in the absence of the latter’s sanction for its implementation, the author debates the admissibility of designation as extraterritorial foreign private law, the admissibility and limits of application of which are sanctioned by the national state.
