On Tuesday, Arab-Israeli leaders filed a petition with the country's Supreme Court against the nation-state law. Opponents say the law legitimizes discrimination against Israeli Arabs, who make up roughly 20 percent of the population.
Regarding the collective rights of Palestinian citizens of Israel and the status of the Arabic language, attorneys argue in the petition that "the Nation-State Law - in violation of global law - does not recognize any collective right of the Arabs as a homeland minority, as opposed to enshrining broad exclusive collective rights for the Jewish population, as if Jews were a minority requiring special protection".
The law includes legally preserving Israel's "democratic" character, its state symbols (national anthem, flag, icon), Jerusalem as the capital of Israel, Hebrew as the official language and the right of return for Diaspora Jewry.
Livni apologized to members of the Druze community "not just for the problematic and discriminatory law, but for the fact that he (Netanyahu) didn't bother showing up here for the discussion, to talk, to stand here and give the answers he owes not just you, the Druze community, but to the entire State of Israel".
The petitioners stress that "a law that denies the civil and national rights of Palestinians in their homeland is racist, colonialist, and illegitimate".
Israel has come under worldwide criticism since passing the Basic Law, which has also come to be known as the "Jewish Nation-State" law.
In a almost 60-page petition, the petitioners maintain that the Israeli Supreme Court must annul the Jewish Nation-State Basic Law as it is racist legislation that contradicts all norms of global law.
But critics, both at home and overseas, say it undermines Israel's commitment to equality for all its citizens outlined in the constitution.
Protesters wave Israeli and Druze flags at a demonstration in Tel Aviv against the nation-state law, on August 4, 2018.
The plenum on "The nation-state law and the harm it does to the values of equality and democracy" was called by the opposition after successfully obtaining the necessary 25 Knesset member (MK) signatures.
The nation-state law does not "contradict or supersede the basic laws that protect and guarantee individual rights of all citizens regardless of ethnicity, religion or gender", she wrote. "The Knesset is the constituent assembly, which defines and determines the Basic Law".
Druze leaders, including three MKs, were first to demand the High Court strike down the "extremist" law.
Prime Minister Benjamin Netanyahu has been trying to placate the Druze with a package of benefits, but efforts to negotiate it have stalled.
It is also argued that, in violation of the United Nations charter, the Jewish Nation-State Basic Law negates the right of the Palestinian people to self-determination.
