CAIRO (Reuters) - Egyptian President Mohamed Mursi negotiated with senior judges on Monday to try to defuse a crisis over his seizure of new powers which set off violent protests reminiscent of an uprising last year that led to the rise of his Islamist movement.
The justice minister said he believed Mursi would agree with Egypt's highest judicial authority on its proposal to limit the scope of the new powers. Mursi's spokesman said the president was "very optimistic Egyptians would overcome the crisis".
But the protesters, some camped in Cairo's Tahrir Square, have said only retracting the decree will satisfy them, a sign of the deep rift between Islamists and their opponents that is destabilising Egypt two years after Hosni Mubarak was ousted.
"There is no use amending the decree," said Tarek Ahmed, 26, a protester who stayed the night in Tahrir, where tents covered the central traffic circle. "It must be scrapped."
One person has been killed and about 370 injured in clashes between police and protesters since Mursi issued the decree on Thursday shielding his decisions from judicial review, emboldened by international plaudits for brokering an end to eight days of violence between Israel and Hamas.
The stock market is down more than 7 percent.
Mursi's political opponents have accused him of behaving like a dictator and the West has voiced its concern, worried by more turbulence in a country that has a peace treaty with Israel and lies at the heart of the Arab Spring.
Mursi's administration has defended his decree as an effort to speed up reforms and complete a democratic transformation. Leftists, liberals, socialists and others say it has exposed the autocratic impulses of a man once jailed by Mubarak.
"President Mursi is very optimistic that Egyptians will overcome this challenge as they have overcome other challenges," presidential spokesman Yasser Ali told reporters, shortly before the president started his meeting with members of Egypt's highest judicial authority, the Supreme Judicial Council.
The council has hinted at a compromise, saying Mursi's decree should apply only to "sovereign matters". That suggests it did not reject the declaration outright. It urged judges and prosecutors, some of whom went on strike, to return to work.
Justice Minister Ahmed Mekky, speaking about the council statement, said: "I believe President Mohamed Mursi wants that."
The presidential spokesman said two Mursi aides had asked to resign over the crisis, but Mursi had yet to accept.
The protesters are worried that Mursi's Muslim Brotherhood aims to dominate the post-Mubarak era after winning the first democratic parliamentary and presidential elections this year.
A deal with a judiciary dominated by Mubarak-era judges, which Mursi has pledged to reform, may not placate them.
A group of lawyers and activists has also challenged Mursi's decree in an administrative court, which said it would hold its first hearing on December 4. Other decisions by Mursi have faced similar legal challenges brought to court by opponents.
Banners in Tahrir called for dissolving the assembly drawing up a constitution, an Islamist-dominated body Mursi made immune from legal challenge. Many liberals and others have walked out of the assembly saying their voices were not being heard.
Only once a constitution is written can a new parliamentary election be held. Until then, legislative and executive power remains in Mursi's hands, and Thursday's decree puts his decisions above judicial oversight.
One Muslim Brotherhood member was killed and 60 people were hurt on Sunday in an attack on the main office of the Brotherhood in the Egyptian Nile Delta town of Damanhour, the website of the Brotherhood's Freedom and Justice Party said.
The party's offices have also been attacked in other cities.
One politician said the scale of the crisis could push opponents towards a deal to avoid a further escalation. Mursi's opponents have called for a big demonstration on Tuesday.
"I am very cautiously optimistic because the consequences are quite, quite serious, the most serious they have been since the revolution," said Mona Makram Ebeid, former member of parliament and prominent figure in Egyptian politics.
Mursi's office repeated assurances that the steps would be temporary, and said he wanted dialogue with political groups to find "common ground" over what should go into the constitution.
Talks with Mursi have been rejected by members of a National Salvation Front, a new opposition coalition that brings together liberal, leftist and other politicians and parties, who until Mursi's decree had been a fractious bunch struggling to unite.
"There is no room for dialogue when a dictator imposes the most oppressive, abhorrent measures and then says 'let us split the difference'," prominent opposition leader Mohamed ElBaradei said on Saturday. He has said he expected to act as the Front's coordinator.
The military has stayed out of the crisis after leading Egypt through a messy 16-month transition to a presidential election in June. Analysts say Mursi neutralised the army when he sacked top generals in August, appointing a new generation who now owe their advancement to the Islamist president.
Though the military still wields influence through business interests and a security role, it is out of frontline politics.
Egypt had hoped to stop the economic rot by signing an initial deal last week for a $4.8 billion loan from the International Monetary Fund. As well as tumbling share prices, yields at a Sunday treasury bill auction rose, putting even more pressure on the government that faces a crushing budget deficit.
"We are back to square one, politically, socially," said Mohamed Radwan of Pharos Securities, an Egyptian brokerage firm.
