Abstract
This chapter defends the principle of collective self-determination as a second principle of natural resource justice. This defence emerges from consideration of the principle of natural resource sovereignty, which appears to be a candidate for agreement from the perspective of Contractualist Common Ownership. The responsible stewardship defence of resource sovereignty is rejected. The collective self-determination defence, however, is shown to get something right. Parties to the original position would indeed accept a principle according to which resource rights must support political communities in the legitimate exercise of collective self-determination, because such self-determination promises to further individuals’ interests in freedom as non-domination. But the principle of collective self-determination appears to support merely a presumptive right of exclusive territorial jurisdiction over natural resources, rather than resource sovereignty. This presumptive right must be abnegated or moderated if it conflicts with basic needs satisfaction, or with the self-determination of other political communities.
