In 2021, the court outlined very narrow circumstances under which a Basic Law can be annulled. A number of petitions were filed challenging the constitutionality of the Nation State Law. While the court did not strike down the law, Supreme Court President Esther Hayut said that “there is one restriction, exceedingly narrow, which is incumbent on the Knesset in its function as the constituent authority, that it is unable to revoke Israel’s essence as a Jewish and democratic state through a Basic Law.”
The court could strike down a Basic Law if it endangers democratic principles such as those that deal “a mortal blow to free and fair elections, core human rights, the separation of powers, the rule of law, and an independent judiciary,” Hayut said.
