  The plebiscitary theorists appeal to occupancy rights may turn out to be a double-edged sword, however. Those who oppose a particular secession might argue that they have occupancy rights in the whole territory of the state in which they are citizens and that to have occupancy rights to a particular portion of it they need not actually be present in it. If a state has a valid claim to a territory and it allows freedom of movement within its boundaries, all citizens are usually understood to have occupancy right to the whole extent of the territory, not just that portion in which they presently reside.
