Police minister and hard-right politician Itamar Ben-Gvir wrote on Twitter that Galant had cracked under pressure from the media and protesters. "I call on the prime minister to dismiss him immediately."
Meanwhile, opposition politicians Yair Lapid and Benny Gantz - a former Israeli prime minister - issued a joint statement saying Netanyahu had "crossed a red line." They called on other members of Likud "not to participate in the destruction of national security."
Organizers of mass protests against the judicial reform are planning week-long daily protests against the proposed law, and demonstrators remain undeterred and are calling for a "week of disruption."
Several Israeli universities on Sunday evening announced a strike in response to Galant's dismissal and the government's reform plans. Several Israeli mayors went on hunger strike demanding an immediate end to the national crisis.
Experts believe that the month-long mass protests are not only about judicial reform, but that the liberal camp is also venting its anger over other serious problems.
It is still unclear how critics of the reform within the government will vote. The coalition has a majority of only four seats in parliament.
Netanyahu's government accuses the Supreme Court of excessive interference in political decisions. In future, the parliament will therefore be able to overturn decisions of the Supreme Court with a simple majority. Critics see the separation of powers as a cornerstone of democracy and warn of a state crisis
