The Islamic law provisions would not apply in the Kurdish north, negotiators said.
Kurdish negotiators this week criticized Khalilzad, a Muslim who helped draft a constitution last year as U.S. envoy to his native Afghanistan, for allegedly supporting the Shiite push for a heavy emphasis on religion in Iraq's new charter.
Both Sunnis and Kurds accused Khalilzad of pushing negotiators too hard to make Monday's deadline, already extended once, and keep the country on a strict timeline that calls for the October constitution referendum and new national elections in December. The United States has viewed the timeline as critical to its hopes of scaling back its 138,000 troops here by spring.
But negotiators credited Khalilzad on Monday with persuading Shiites and Kurds to take more time to try to bring Sunnis into support of the draft.
Mutlak expressed shock at how close other negotiators seemed to have come Monday at passing the draft without further consulting Sunnis. ""Frankly, I don't trust them anymore," he said afterward.
"Congratulations on your constitution," Mutlak told Hamoudi, the Shiite committee chairman, early Tuesday after the session. "Yours," Hamoudi said. Mutlak disagreed, grimly: "Yours."
Defeating the constitution in an Oct. 15 referendum would require two-thirds of voters in three of Iraq's provinces to reject it. Sunnis are thought capable of securing such a vote in at least two provinces in a fair election. If the parliament had failed to submit a draft Monday, it would have dissolved and elections would have been held for a new assembly to try to devise a new draft. If the referendum fails Oct. 15, it will trigger the same series of events.
Because of insurgent threats and boycott demands from their leaders, the majority of Iraq's Sunnis stayed out of January national elections that seated the current parliament and government. The move greatly diminished their clout in the government and in the constitutional talks. Many Sunni leaders said they recognize that was a mistake, and have been mobilizing followers to vote "no" in the constitutional referendum.
