Illegal occupation settements

Uti possidetis juris is widely acknowledged as the doctrine of customary international law that is central to determining territorial sovereignty in the era of decolonization.

The doctrine provides that emerging states presumptively inherit their pre-independence administrative boundaries.

Applied to the case of Israel, uti possidetis juris would dictate that Israel inherit the boundaries of the Mandate of Palestine as they existed in May, 1948.

The doctrine would thus support Israeli claims to any or all of the currently hotly disputed areas of Jerusalem (including East Jerusalem), the West Bank, and even potentially the Gaza Strip (though not the Golan

Heights).
