Another member, film director Khaled Youssef, said the panel should now work as a body promoting national unity and working to safeguard the alliance of liberal and secular groups that supported Morsi's ouster.
The draft leaves uncertain which would be called first after its adoption—the parliament elections or presidential election.
It says only the first must be held within 90 days of its adoption, with the next within six months after.
The ambivalence is thought to be designed to give Mansour legal leeway to decide which to call first, though the original roadmap for the transition set by the military after Morsi's ouster called for parliamentary first.
The charter requires presidents to declare their financial assets annually, and empowers lawmakers to vote out an elected president with a two-third majority.
It also bans parties founded on religion or sect and unequivocally states the equality of men and women.
It also guarantees the rights of Egyptians with special needs and the elderly.
But it also leaves the military with unfettered freedom to choose the country's defense minister from within its ranks and grants him immunity for two, four-year presidential terms.
