JERUSALEM, March 12 -- Israel's parliament approved on Wednesday a basic law which requires a referendum in order to relinquish sovereign Israeli lands amid any future peace agreement.

The law was authorized by 68 parliament members from the coalition. The members of the Israeli opposition did not take part in the discussion and the vote as they are boycotting the discussion of overall three bills pushed for approval this week by the coalition, over what they dubbed the coalition's "political brutality."

There is already a law in place requiring holding a referendum on giving up sovereign lands. However, this amendment to the status of the bill makes it a basic law, which means a key constitutional law that dictates the roles and the conduct of the Israeli authorities and overall state policies.

There are only 14 other basic laws intact since the establishment of the state of Israel and those rules could not be revoked or appealed without a special majority.

The bill, which was pushed by members of the nationalistic and settlements-advocating Jewish Home party, includes the Golan Heights up north, Jerusalem and other parts.

It does not pertain to the West Bank lands that were occupied by Israel amid the 1967 Mideast War but does pertain to east Jerusalem, which Israel annexed following the same war.

This is the third bill that the Israeli parliament approved in recent days in a marathon to approve three controversial bills. The first one, the governance bill, raises the electoral threshold to 3.25 percent and makes it hard for the opposition to overthrow a presiding government.

The second bill, approved earlier on Wednesday, calls for criminal sanctions against ultra-Orthodox draft dodgers. Up until 2012, ultra-Orthodox youths were exempt from military service. The bill calls for the enlistment of thousands of ultra-Orthodox by the beginning of 2017.
