Should we worry about bill requiring Knesset supermajority to negotiate on Jerusalem?

 Of course, the bill has a political dimension, and not an innocuous one. Its purpose is to thwart the peace talks. The introductory notes show that the bill's intention is to even prevent "a debate” on the status of Jerusalem. What is more, today the Basic Law on Jerusalem, the Capital of Israel requires a 61-MK majority to cede portions of the city to a foreign entity - but there is no restriction on raising the issue in peace negotiation.
Other than that, this bill also has several legal flaws. Since the issue of Jerusalem is one of the core issues that will be addressed, in one way or another, in a final-status agreement with the Palestinians, the bill contradicts previous commitments Israel made. The Oslo Accords, for one, stipulate that Jerusalem will feature - alongside other issues like the Palestinian refugees, the settlements, security arrangements and borders - in the final-status stage of the talks.
