After the occupation of East Jerusalem in 1967, Israel issued a law that sought to illegally annex the newly captured territory. This law transmitted administrative responsibilities and the power of government to the State of Israel, effectively enabling Jerusalem authorities to extend Israeli laws, jurisdiction and administration to East Jerusalem.
Moreover, the new municipal borders of East Jerusalem were expanded from 5.6 square kilometers to approximately 72 square kilometers.
Later in 1980, the Israeli Knesset issued the “Basic Law: Jerusalem as Capital of Israel,” which declared that a “full and unified Jerusalem is the capital of Israel.”
This action was rejected and resisted by the Palestinians as well as the United Nations Security Council and General Assembly, who considered Jerusalem occupied territory.
Accordingly, any claim made by the occupying power to extend its sovereignty and influence over East Jerusalem is void under international law.
