Only King Abdullah II has the legal ability to break the recently signed multibillion-dollar gas deal with Israel, according to Jordan’s Constitutional Court.

The court’s decision came in response to a parliamentary proposal to terminate its natural gas deal with Israel, reported The Jerusalem Post on Tuesday.

Under Jordan’s constitution, only the king can amend or cancel any ratified international agreements, and in addition, the proposal is “completely inconsistent” with obligations stipulated in the 1994 Jordan-Israel peace agreement, the court said as cited by the Post.

In January, Israel began pumping its first supply of natural gas to Jordan via the Leviathan gas field, off the Israeli coast, under the terms of a $10 billion dollar gas deal agreement with the kingdom.

The Leviathan is the largest natural gas field ever discovered off the coast of Israel, lying some 77 miles west of Haifa. It is estimated to have 22 trillion cubic feet of gas, enough to make the country a gas exporter for the first time in its history, which would bring billions of shekels into state coffers.
