Israel's high court narrowly upheld on Sunday a controversial law that bars West Bank Palestinians from living with spouses and children who are Arab citizens of Israel.

The law, passed in 2002 at the height of Israeli-Palestinian fighting, is believed to have kept hundreds, and possibly thousands, of Palestinians from moving to Israel to live with their families. An expanded panel of 11 judges voted 6-5 against a petition to strike it down.

"This is a very black day for the state of Israel and also a black day for my family and for the other families who are suffering like us," said Muad el-Sana, an Israeli-Arab attorney who is married to a Palestinian woman from the West Bank town of Bethlehem.

"The government is preventing people from conducting a normal family life just because of their nationality," el-Sana told Israel Radio, minutes after the ruling was announced.

The government has repeatedly said the law was based on security concerns, but the restrictions also cut to a more sensitive demographic issue -- the fear that the country's Jewish majority could be threatened if too many Palestinians are granted citizenship.

Critics of the law have slammed it as racist and discriminatory. Amnesty International called on Israel to repeal the law, calling it "explicitly discriminatory."

"I had hoped and expected the high court to be the last arena for protecting democracy," lawmaker Zehava Galon of the dovish Meretz Party told Israel Radio. "In essence we are talking about a means to halt the demographic threat. There are no real security issues."

Orna Kohn, an attorney from Adalah, a group that fights for the rights of Israeli-Arabs, said the court's ruling causes "grave damage to the basic rights of thousands of people."

"I am afraid the message the Supreme Court relayed today will allow additional racist legislation," she told Israel Radio.

The court had granted el-Sana's wife, Abir, a temporary injunction preventing her deportation. But el-Sana said the high court's ruling made it almost impossible for them and their two children, aged 2 and five months, to live together.
