JERUSALEM (AP) — Israel's parliament was set to vote Monday on whether to renew a temporary law first enacted in 2003 that bars Arab citizens of Israel from extending citizenship or even residency to spouses from the occupied West Bank and Gaza.

Critics, including many left-wing and Arab lawmakers, say it's a racist measure aimed at restricting the growth of Israel's Arab minority, while supporters say it's needed for security purposes and to preserve Israel's Jewish character.

The law creates an array of difficulties for Palestinian families that span the war-drawn and largely invisible frontiers separating Israel from east Jerusalem, the West Bank and Gaza, territories it seized in the 1967 war that the Palestinians want for a future state.

“You want your security, it’s no problem, you can check each case by itself,” said Taiseer Khatib. His wife of more than 15 years, from the West Bank city of Jenin, must regularly apply for permits to live with him and their three children in Israel.

“There’s no need for this collective punishment just because you are Palestinian," he said.

Israel's dominant right-wing parties strongly support the law, and it has been renewed every year since being enacted. But Israel's new government includes opponents of the measure, and the right-wing opposition led by former Prime Minister Benjamin Netanyahu — aiming to embarrass the government — has warned it won't provide the votes needed to renew the law.

Ahead of the vote, Israel's new prime minister, Naftali Bennett, called on Netanyahu to join him in renewing the law. “Harming state security for a quarter of a political point is not the right thing to do,” he said.

Parliamentary debates stretched late into the night Monday, and it remained unclear when the vote to renew the temporary law would be held. It was set to expire Tuesday night.

Dozens of families held a demonstration outside the Knesset, Israel's parliament, ahead of the vote, which was expected late Monday.

“We want stability in this country, like anyone else,” said Maryam Abu Arar, from the West Bank town of Bethlehem, who requires a permit to live with her husband and four children in Israel. “We want to live in a democratic country, with peace and security for us as well.”

The Citizenship and Entry into Israel Law was enacted as a temporary measure in 2003, at the height of the second intifada, or uprising, when Palestinians launched scores of deadly attacks inside Israel. Proponents said Palestinians from the occupied West Bank and Gaza were susceptible to recruitment by armed groups and that security vetting alone was insufficient.

The law has been continually renewed even after the uprising wound down in 2005 and the number of attacks plummeted. Today, Israel allows more than 100,000 Palestinian workers from the West Bank to enter on a regular basis.

“It was passed in the middle of the intifada, and now we are in a very different period in time," said Yuval Shany, a legal expert at the Israel Democracy Institute. Not only are attacks far rarer, but Israel has vastly improved its technological abilities to monitor Palestinians who enter, he said. “I don’t think the security argument is very strong at this point in time.”

Because of the law, Arab citizens have few if any avenues for bringing spouses from the West Bank and Gaza into Israel. The policy affects thousands of families.

Male spouses over the age of 35 and female spouses over the age of 25, as well as some humanitarian cases, can apply for the equivalent of a tourist permit, which must be regularly renewed. The holders of such permits are ineligible for driver's licenses, public health insurance and most forms of employment. Palestinian spouses from Gaza have been completely banned since the militant Hamas group seized power there in 2007.

The law does not apply to the nearly 500,000 Jewish settlers who live in the West Bank, who have full Israeli citizenship. Under Israel's Law of Return, Jews who come to Israel from anywhere in the world are eligible for citizenship.

Israel's Arab minority, which makes up 20% of the population, has close familial ties to Palestinians in the West Bank and the Gaza Strip and largely identifies with their cause. Arab citizens view the law as one of several forms of discrimination they face in a country that legally defines itself as a Jewish nation-state.

“This law sees every Palestinian as an enemy and as a threat, just because of his ethnic and national affiliation," said Sawsan Zaher, a lawyer with Adalah, an Arab rights group that has challenged the law in court. "The political message is very racist and very dangerous.”

Palestinians who are unable to get permits but try to live with their spouses inside Israel are at risk of deportation. Couples that move to the West Bank live under Israeli military occupation. If their children are born in the West Bank, they would be subject to the same law preventing spouses from entering Israel, though there is an exception for minors.

The citizenship law also applies to Jewish Israelis who marry Palestinians from the territories, but such unions are extremely rare.

Human Rights Watch pointed to the law as an example of the widespread discrimination faced by Palestinians — both inside Israel and in the territories it controls — in a report earlier this year that said such practices amount to apartheid.

Israel rejects such allegations and says Jewish and Arab citizens have equal rights. Arab citizens have the right to vote, and the new government for the first time includes an Arab faction, which is opposed to the citizenship law.

But even as Defense Minister Benny Gantz, a political centrist, recently urged the right-wing opposition to support the law on security grounds, he also evoked demographic concerns.

“This law is essential for safeguarding the country’s security and Jewish and democratic character, and security considerations need to be put before all political considerations,” Gantz said in a statement.

Ahmad Tibi, a prominent member of an Arab opposition party, called on fellow lawmakers to strike the law down.

“They should look at the eyes of these children and these families and then vote to prevent this most racist law," he said as he met with the demonstrators. "These families should be allowed to live normally as all other families, wherever they decide to live.”
