CAIRO (AP) — Islamists approved a draft constitution for Egypt early today without the participation of liberal and Christian members, seeking to pre-empt a court ruling that could dissolve their panel with a rushed, marathon vote that further inflames the conflict between the opposition and President Mohammed Morsi.

The vote by the constituent assembly advanced a charter with an Islamist bent that rights experts say could give Muslim clerics oversight over legislation and bring restrictions on freedom of speech, women’s rights and other liberties.

The draft, which the assembly plans to deliver to the president Saturday, must be put to a nationwide referendum within 30 days. Morsi said Thursday it will be held “soon.”

The Islamist-dominated assembly that has been working on the constitution for months raced to pass it, voting article by article on the draft’s more than 230 articles for more than 16 hours. The lack of inclusion was on display in the nationally televised gathering: Of the 85 members in attendance, there was not a single Christian and only four women, all Islamists. Many of the men wore beards, the hallmark of Muslim conservatives.

For weeks, liberal, secular and Christian members, already a minority on the 100- member panel, have been withdrawing to protest what they call the Islamists’ hijacking of the process.
