Israel’s borders and territorial scope are a source of seemingly endless debate. Remarkably, despite the intensity of the debates, little attention has been paid to the relevance of the doctrine of uti possidetis juris to resolving legal aspects of the border dispute. 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 the disputed areas of the “West Bank”, East Jerusalem and (potentially) the Gaza Strip.
