Netanyahu has dismissed the protests, now in their third week, as a refusal by leftist opponents to accept the results of last November's election, which produced one of the most right-wing governments in Israel's history.
The protesters say the future of Israeli democracy is at stake if the plans, which would tighten government control over judicial appointments and limit the Supreme Court's powers to review government decisions, go through.
As well as threatening the independence of judges and weakening oversight of the government and parliament, they say the plans will undermine the rights of minorities and open the door to more corruption.
