Netanyahu, who is on trial for corruption, has made the legal changes the centerpiece of his new government's agenda and the surging opposition to them is presenting an early challenge for the Israeli leader.

The overhaul would weaken the power of the Supreme Court, granting legislators the ability to pass laws the court has struck down with a simple majority, as well as give the government greater power over the appointment of judges and limit the independence of government legal advisers.

The proposed changes have sparked an outcry from the Supreme Court's top justice, who in rare criticism called the overhaul an ``unbridled attack on the justice system.'' The country's attorney general has also spoken out against the plan, as have many of her predecessors.

Despite the opposition, Netanyahu told a meeting of his Cabinet that voters cast their ballots in the November elections in support of his campaign promise to overhaul the justice system.

``We will complete legislating the reforms in a way that will correct what needs correcting, will totally protect individual rights, and will restore the public's faith in the justice system that so much requires this reform,'' Netanyahu said.

There have been calls in the past to reform Israel's justice system, which was given greater clout in the 1990s and has been seen since by critics as being too interventionist in the process of lawmaking.

But the sweeping changes sought by Netanyahu's justice minister have raised an alarm among opponents who see them as a death knell to Israel's system of checks and balances and in turn, its democratic fundamentals.

Netanyahu and his allies see the changes as a way to ease the process of governance and recalibrate what they say is an imbalance between the country's executive and judicial branches.

The proposed changes tabled weeks after the government was sworn in, have exposed how deeply polarized Israeli society is, torn between preserving the country's liberal and democratic ideals or shifting away from them.

They have also shown how quickly the country's government, it's most right-wing ever, is intent on advancing its policies, many of which have sparked criticism, including from unexpected quarters.

Netanyahu heads a government of ultranationalist and ultra-Orthodox parties who at times in the past have seen their agendas thwarted by Supreme Court decisions or unfavorable counsel by government legal advisers.

That prompted them to make sure the legal changes were a top priority during negotiations to form the government. Netanyahu, eager to return to power under the shadow of his corruption trial, appeared to be generous to his partners in the talks.

Israel's ceremonial President Isaac Herzog has stepped it to try to bridge the divide over the judicial changes and has been holding meetings to try to reach some consensus on the way forward. In a statement, Herzog said he was working to avert ``a historic constitutional crisis'' that could emerge over the legal changes. Hundreds protested outside his residence in Jerusalem on Saturday.

Netanyahu has claimed the overhaul will be carried out cautiously and with parliamentary oversight. But critics say such a profound change to the system requires a more delicate and thoughtful approach.

Critics also say the changes could help Netanyahu evade conviction in his corruption trial, or make the trial disappear altogether. Netanyahu denies wrongdoing.
