Cairo (CNN) -- Whether a draft constitution approved by an assembly will move Egypt toward being a freer and more open society is still in question, experts say.
The assembly early Friday approved dozens of amendments as delegates worked through the night to cobble together the draft. Citizens will vote in two weeks to determine if the constitution will go into effect.
The outcome of the vote will set the tone for the future of one of the most important countries in a region that is quaking amid the conflict in Syria, violence still smoldering in Iraq and a continuing volatile standoff between Israelis and Palestinians.
It will also be a reflection of President Mohamed Morsy's government, experts say. Morsy was voted into office after the popular uprising in 2011 that toppled President Hosni Mubarak. Some have said Morsy's push for a new constitution is a power grab that echoes Egypt's past.
Seeds of Egypt's past sown long ago
Morsy's Muslim Brotherhood party pushed through the 234-article draft in just 21 hours from Thursday into Friday. Frustrated Coptic Christians and liberals earlier had walked out, complaining their views were not getting enough consideration.
Members voted on each article separately, discussed objections by dissenters and made alterations.
Morsy was expected to receive a copy of the constitution Friday.
Opinion: Don't blame Muslim Brotherhood for Morsy power grab
A quick glimpse at the articles show that the language deals with individuals' civil rights, particularly how security forces and the justice system treats them. There's wording that prohibits arbitrary arrest and detention and ensures due process, a sensitive topic in Egypt. Mubarak and his loyalists are blamed for jailing and harshly mistreating innocents in the years before and especially during last year's uprising.
Protesters to Morsy: Roll back your decree or leave
Anyone jailed cannot be interrogated without an attorney present, and if detainees don't have one, the judicial system must appoint one, one article stipulates, and phone conversations, electronic correspondence and other communication cannot be tapped without a warrant.
Friday morning, the assembly's head, Hossam al-Ghiriyani, asked if everyone agreed to the 234 articles. After a show of hands, he said, "Agreement by consensus. May God bless you." The room broke into applause, and everyone stood while the national anthem played.
While the articles sound democratic, the fine print indicates otherwise, some independent rights experts say.
"Moving a flawed and contradictory draft to a vote is not the right way to guarantee fundamental rights or to promote respect for the rule of law," said Joe Stork, deputy Middle East and North Africa director at Human Rights Watch.
He told CNN on Friday that key rights are ignored in the draft.
"It guarantees 'freedom of expression,' but you cannot insult the Prophet. You cannot defame the Prophet," Stork said.
While it might be all right for such action to be considered a civil offense, it should not be "a criminal one as this document suggests," he said.
The draft addresses freedom of religion, Stork notes, "but you have to be a Christian, Jew and Muslim."
It doesn't address the Baha'is, he said, a group that has been persecuted in various countries for their faith.
Opinion: A new Egypt must learn political compromise
Other observers were more optimistic.
"The draft constitution will end the state of political division, because it will cancel the constitutional decrees that the president issued," said Dawood Basil, a Cairo University constitutional law expert. "I feel overwhelming joy after hearing the final wording of the articles."
Some critics argue the constitution could move Egypt closer to Sharia law.
A 1971 constitution in place under Mubarak was "more open and protective of individual rights," said Mustapha Kamel Sayed, a professor of political science at Cairo University.
The preamble includes language pertaining to women, stating that they are equal to men but also accentuating their role as mothers.
The constitution says: "There is no dignity for a nation which does not honor women; women and men are equal, for they are the fort of motherhood, half of the society and partners in all the gains and national responsibilities."
Citing the family as "the foundation of society," the document guarantees free maternal health care and promises to reconcile "a woman's duties toward her family" and her job.
But Heba Morayef, the Egypt director for Human Rights Watch, argued that the language regarding women is too vague. She worries that the mention of women's family role will trump other freedoms.
The United Nations' high commissioner for human rights, Navi Pillay, urged Morsy to reconsider the draft, saying a number of measures contained in it are incompatible with international human rights law. She called them "not yet sufficient."
Some people in Egypt are also doubtful the draft will bring them the freedoms they fought so hard for last year.
Tens of thousands of protesters Friday packed Tahrir Square, the epicenter of 2011's revolution. They prayed and listened to a cleric call Morsy a "pharaoh." Women in the crowd spoke of their concerns about possible discrimination resulting from the constitution.
Demonstrations have become violent at times, and protesters pitched a tent city at a traffic roundabout. Food vendors have set up stands in the middle of the street and protest leaders have walked across a sound stage leading chants.
Opposition factions have called for another mass demonstration in Tahrir Square starting near daybreak Saturday.
The Muslim Brotherhood has called for its own demonstration outside Cairo University on Saturday, in what would be the biggest public show of support for Morsy.
