Declarations of State Land in the West Bank are declarations by Israeli authorities that Palestinian land is "state land", that is, land that may be legally administered by an occupying power on a temporary basis under international law, on the theory that the occupier is holding the territory in trust until sovereignty can be restored. It was and is the principal method used by the governments of Mandatory Palestine and Israel respectively, to acquire land from Palestinians and sell it to Israeli settlers. According to B'Tselem, it was used to expropriate 16% of the West Bank.
