The standard justifications for control over territory appeal to goods that are delivered to persons who inhabit the territory (self-determination, justice). This raises the question: What justifies territorial rights in unoccupied places? This question is relevant to a pressing practical question concerning the permissibility of national and corporate interests in mining or gas drilling and other resource extraction activities in unoccupied places, some of which were either technologically impractical or prohibitively expensive in the past, but which now are possible. The territorial rights literature does not focus on unoccupied places, treating resource rights there as an extension of rights in occupied places, thereby suggesting that these activities could be justified in the same way. This article examines the distinctive normative contours of unoccupied spaces, and so considers a number of possible arguments to justify such rights. It focuses on rights to resources in relation to three different kinds of unoccupied places and suggests that the stewardship justification is the most promising (although there is some role for other arguments in relation to certain kinds of unoccupied places).
