Is territorial jurisdiction over natural resources justified? This paper argues that a freedom-based account of self-determination coupled with ‘functionalist’ justifications of territorial right support territorial jurisdiction over natural resources. This justification simultaneously gives rise to limits on the permissible exercise of the right: the principles of reciprocity and generality, and of equal freedom. This ‘reciprocal’ view on territorial jurisdiction over natural resources, defended here, differs from two alternatives: the traditional sovereignty view on the one hand and the transnational jurisdiction view—which (...) favours the transfer of sovereignty over natural resources from states to transnational institutions—on the other hand.
