THE HAGUE : The UN’s top court, in a sweeping opinion on Friday, said that Israel’s decades-long occupation of Palestinian territory was “illegal” and needed to end as soon as possible.The advisory opinion by The Hague-based International Court of Justice was immediately slammed as a “decision of lies” by Israel, but welcomed by the Palestinian presidency, which called it “historic”.

The ICJ’s statement, called an “advisory opinion”, is not binding, but it comes amid mounting concern over the death toll and destruction in Israel’s war against Hamas sparked by the group’s brutal October 7 attacks.

It is also likely to increase diplomatic pressure on Israel, whose lawmakers on Thursday voted to oppose a Palestinian state, calling it an “existential threat”. In The Hague, ICJ presiding judge Nawaf Salam said: “The court has found… that Israel’s continued presence in the Palestinian Territories is illegal.”

Israel is “under the obligation to bring to an end its unlawful presence as rapidly as possible,” the judge said in its finding, read at the Peace Palace, seat of the ICJ. The ICJ added that Israel was “under an obligation to cease immediately all new settlement activities and to evacuate all settlers” from occupied land.

Israel’s policies and practices, including the maintenance of a wall between the territories, “amount to annexation of large parts” of the occupied territory, the court said. Israeli Prime Minister Benjamin Netanyahu slammed the ICJ’s opinion as a “decision of lies”.

“The Jewish people are not occupiers in their own land -– not in our eternal capital Jerusalem, nor in our ancestral heritage of Judea and Samaria” (the occupied West Bank), Netanyahu said in a statement.  Palestinian foreign minister Riyad Al-Maliki called it a “watershed moment”.

A separate, high-profile case that South Africa has brought before the court alleges that Israel has committed genocidal acts during its Gaza offensive.

South Africa, in a statement, called upon the international community “to bring an immediate end to the occupation and the gross violations of international humanitarian and human rights law being perpetrated by Israel against the Palestinian people”.

 In late 2022, the UN’s General Assembly asked the ICJ to give an “advisory opinion” on the “legal consequences arising from the policies and practices of Israel in the Occupied Palestinian Territory, including East Jerusalem”.

The ICJ held a week-long session in February to hear submissions from countries following the request — supported by most countries within the Assembly. During the hearings, most speakers called on Israel to end its 57-year occupation. They warned a prolonged occupation posed an “extreme danger” to stability in the Middle East and beyond.

But the United States said Israel should not be legally obliged to withdraw without taking its “very real security needs” into account. Israel did not take part in the oral hearings.

The ICJ’s statement, called an “advisory opinion”, is not binding, but it comes amid mounting concern over the death toll and destruction in Israel’s war against Hamas sparked by the group’s brutal October 7 attacks.

Far-right groups that block aid to Gaza receive tax-deductible donations from US and Israel.  Firstly, the court should examine the legal consequences of what the UN called “the ongoing violation by Israel of the right of the Palestinian people to self-determination”.

In its answer, the ICJ’s judges said Israel’s “unlawful policies and practices are in breach” of its “obligation to respect the rights of the Palestinian people and their right to self-determination”.

In June 1967, Israel crushed some of its Arab neighbours in a six-day war, seizing the West Bank and East Jerusalem, at the time annexed by Jordan, the Golan Heights from Syria, and the Gaza Strip and Sinai Peninsula from Egypt.

Israel then began to settle the 70,000 square kilometres (27,000 square miles) of seized Arab territory. The UN later declared the occupation of Palestinian territory illegal, and Cairo regained Sinai under its 1979 peace deal with Israel.

The ICJ also was asked to look into the consequences of what it described as Israel’s “adoption of related discriminatory legislation and measures”.  In this finding, the ICJ said a “regime of comprehensive restrictions imposed by Israel on Palestinians consisted of systemic discrimination based on race, religion or ethnic origin.”

The ICJ rules in disputes between states. Normally, its judgements are binding but it has few means to enforce them. In this case, however, the opinion is non-binding, although most advisory opinions are in fact acted upon.

The ICJ has previously issued advisory opinions on the legality of Kosovo’s 2008 declaration of independence from Serbia and apartheid South Africa’s occupation of Namibia. It also handed down an opinion in 2004 declaring that parts of the wall erected by Israel in the occupied Palestinian territory were illegal and should be torn down. Israel has not complied with that ICJ ruling.
