Israel's laws prevent Palestinian refugees and IDPs from returning to their homes of origin. Palestinians must be able to prove that they were in the state of Israel on or after 14 July 1952, or the offspring of a Palestinian who meets this condition. Due to the fact that most Palestinian refugees were displaced outside the territory of the state of Israel on or after this date, they are unable to resume domicile in their homeland. Israel's longstanding occupation of the West Bank, eastern Jerusalem, and Gaza Strip and related military orders and administrative procedures prevents refugees from returning to these areas.
